The Guide to the NEBOSH National Diploma in Occupational Health and Safety

(November 2015 specification)

1. Introduction

The NEBOSH National Diploma is the flagship NEBOSH qualification and is the first UK

vocational qualification to be developed specifically for health and safety professionals. The

National Diploma has become established as the most popular professional qualification for

safety and health practitioners in the UK, with over 11000 students having achieved the

qualification since its introduction in 1988.

The NEBOSH National Diploma is the qualification for aspiring health and safety

professionals, building directly upon the foundation of knowledge provided by the NEBOSH

National General Certificate. It is designed to provide students with the knowledge and

understanding required for undertaking a career as a health and safety practitioner and it also

provides a sound basis for progression to postgraduate study.

1.1 Qualification withdrawal (transitional arrangements)

The NEBOSH National Diploma in Occupational Health and Safety (November 2015

specification) has been replaced by the NEBOSH National Diploma for Occupational Health

and Safety Management Professionals (July 2020 specification).

New learners must be enrolled and/or registered to the November 2015 specification by 30

November 2021.

Learners will then have until the following final assessment dates to complete their

qualification:

Units A, B and C – February 2026

Unit DNI – February 2026

If the learner does not complete their qualification at or before the above dates, they will need

to take the assessments for the revised Diploma if they still wish to gain the qualification.

1.2 Benefits for employers

Accidents and work-related ill-health affect all types of workplaces and occupations. In the

year 2014/15 the following UK statistics were reported by the Health and Safety Executive:

• 142 people killed at work;

• 1.2million people suffered from work-related illness;

• 2358 Mesothelioma deaths due to past exposures (2013 figures);

• 13000 deaths occur each year from work-related lung disease and cancer due to past

exposure (primarily from dust and chemicals at work);

• 76000 other injuries reported under the Reporting of Injuries, Diseases and Dangerous

Occurrences Regulations 2013;

• 611000 other injuries occurred at work (Labour Force Survey);

• 27.3million days lost due to work-related illness and workforce injury;

• Mental ill-health gave rise to most working days lost (an estimated 234000 cases);

• £14.3billion is the estimated cost of injuries (£4.96billion) and ill health (£9.46billion) from

working conditions (2013/14 figures).

In addition to the direct costs of sick pay and absence, employers can find themselves dealing

with criminal prosecution, claims for compensation, adverse publicity and harm to both

The Guide to the NEBOSH National Diploma in Occupational Health and Safety

(November 2015 specification)

business reputation and profitability. The following enforcement actions were taken in Great

Britain during 2014/15:

• 586 cases were prosecuted by the HSE in England and Wales;

• 70 cases were prosecuted by Local Authorities in England and Wales;

• 72 cases were prosecuted by the Procurator Fiscal in Scotland;

• 12430 enforcement notices were issued by all enforcing authorities.

In addition to prosecutions and enforcement notices the HSE is also able to charge Fees for

Intervention (FFI) for those organisations that are found to have made a ‘material breach’. The

FFI is currently £129 per hour.

The management of health and safety in the workplace is not only a legal obligation and a

moral imperative, it also makes good business sense. Qualified health and safety

professionals are an asset to their organisation. They can help to reduce costs by preventing

accidents and ill health of employees, while at the same time avoiding unnecessary expense

by over-reacting to trivial risks. This in turn can lead to improved productivity and the raising

of workforce morale. Effective health and safety management should be recognised as an

essential element of a successful management strategy.

Courses leading to the NEBOSH National Diploma may be taken in a variety of formats and

at a pace to fit around the needs of the individual and the business. Its unitised structure

recognises success as the student progresses. Its practical approach promotes the

application of the knowledge acquired on the course to problem solving in the student’s own

workplace.

1.3 Designatory letters

Holders of the NEBOSH National Diploma in Occupational Health and Safety may use the

designatory letters ‘DipNEBOSH’ after their name.

1.4 Professional membership

The qualification meets the academic requirements for application for Graduate Membership

(Grad IOSH) of the Institution of Occupational Safety and Health (IOSH – www.iosh.co.uk).

This is the first step to becoming a Chartered Health and Safety Practitioner as a Chartered

Member of IOSH (CMIOSH).

Holders of the National Diploma are able to waive the Board of Certified Safety Professionals’

Associate Safety Professional (ASP) examination so that, if they meet all other requirements,

they may sit directly for the Certified Safety Professional (CSP) examination.

Holders of the NEBOSH National Diploma in Occupational Health and Safety and either the

NEBOSH National or International Certificate in Construction Health and Safety meet the

headline entrance criteria requirements for Registered Construction Safety Practitioner

(RMaPS) and membership of the Association for Project Safety (APS).

The National Diploma is also accepted by the International Institute of Risk and Safety

Management (IIRSM) as meeting the academic requirements for full membership (MIIRSM).

The Guide to the NEBOSH National Diploma in Occupational Health and Safety

(November 2015 specification)

1.5 Qualification level and UK accreditation

The NEBOSH National Diploma in Occupational Health and Safety (November 2015

specification) is accredited and credit rated by the Scottish Qualifications Authority (SQA -

www.sqa.org.uk) for delivery across the UK. It is rated within the Scottish Credit and

Qualifications Framework (SCQF - www.scqf.org.uk) at SCQF Level 10 with 51 SCQF credit

points. The accreditation end date for this qualification is 30 November 2021.

For users in England, Wales and Northern Ireland, this is comparable to a Vocationally-

Related Qualification (VRQ) at Level 6 within the Regulated Qualifications Framework (RQF)

and Qualifications and Credit Framework (QCF), or Honours Degree standard.

For further information please refer to the “Qualifications can cross boundaries” comparison

chart issued by the UK regulators, available from the SQA website (www.sqa.org.uk).

1.6 Key topics covered

• Managing health and safety

• Hazardous agents in the workplace

• Workplace and work equipment safety

• Practical application of health and safety theory

1.7 Course tuition and private study time requirements

Unit A: 103 hours tuition and 85 hours private study Total: 188 hours

Unit B: 65 hours tuition and 50 hours private study Total: 115 hours

Unit C: 70 hours tuition and 50 hours private study Total: 120 hours

Unit DNI: 5 hours tuition and 72 hours private study Total: 77 hours

A programme of study therefore needs to be based around a minimum of 243 taught hours

and approximately 257 hours of private study for an overall total of 500 Hours.

A full-time block release course would be expected to last for a minimum of 7-weeks (35-

working days) and a part-time day release course would be spread over at least 30-weeks.

The tuition hours should be added to the recommended private study hours to give the

minimum number of hours for students studying by open or distance learning.

Tuition time should normally be allocated proportionate to the tuition time for each element but

may require adjustment to reflect the needs of a particular student group.

Quoted hours do not include assessment time, ie, sitting written examinations.

The Guide to the NEBOSH National Diploma in Occupational Health and Safety

(November 2015 specification)

1.8 Entry requirements

The NEBOSH National Diploma syllabus assumes that students will have knowledge of health

and safety equivalent to that provided by the NEBOSH National General Certificate (NGC).

The achievement of the NGC or direct equivalent prior to undertaking the Diploma

course is highly recommended, because of the demands of high level study, the time

commitment required and the complementary nature of the NEBOSH NGC and National

Diploma. Further information on the NEBOSH National General Certificate can be found via

our website www.nebosh.org.uk.

It should be noted that currently the assessments are offered (and must be answered) in

English only. The qualification includes a requirement to write an extended assignment based

on the student’s own workplace, which must also be in English. Students should discuss this

requirement with the accredited course provider before undertaking the qualification.

Students must satisfy any entry requirements specified by the course provider. Acceptance

on to the programme may be based on the admission tutor’s judgement on the student’s ability

to benefit from the programme.

1.9 Minimum standard of English required for students

The standard of English required by students studying for the NEBOSH National Diploma must

be such that they can both understand and articulate the concepts contained in the syllabus.

It is important to stress that it is the responsibility of Learning Partners to determine their

learners’ standards of proficiency in English.

NEBOSH recommends that learners undertaking this qualification should reach a minimum

standard of English equivalent to an International English Language Testing System score of

7.0 or higher in order to be accepted onto a National Diploma programme.

For further information please see the latest version of the IELTS Handbook or consult the

IELTS website: http://www.ielts.org/institutions/test_format_and_results.aspx.

Learners wishing to assess their own language expertise may consult the IELTS website for

information on taking the test: http://www.ielts.org/faqs.aspx.

1.10 Legislation

The syllabus refers to UK legislation. Where the syllabus refers to the legislative system of

England and Wales, learners may refer to the legislative systems and requirements that apply

in Scotland or Northern Ireland, provided that these references are clearly indicated as such.

If this qualification is delivered overseas, accredited course providers may refer to examples

of local legislation as part of the course programme but examination questions will refer to UK

legislation only.

The Guide to the NEBOSH National Diploma in Occupational Health and Safety

(November 2015 specification)

1.11 Legislative updates

Relevant new legislation will become examinable in detail six months after its date of

introduction. However, learners will be expected to be up-to-date at the time of the

examination and, whilst detailed knowledge will not be expected, reference to new or

impending legislation, where relevant to an examination question, will be given credit.

Please note, NEBOSH will not ask questions related to legislation that has been repealed,

revoked or otherwise superseded.

NB: Learning Partners are expected to ensure their course notes remain current with regard

to new legislation. NEBOSH issues bi-annual legal updates to assist Learning Partners with

this process.

1.12 National Occupational Standards (NOS) and best practice

The syllabus is mapped to the relevant National Occupational Standard (NOS). The mapping

of the syllabus against each of the above standards can be found on pages

15-18.

1.13 Qualification type

NEBOSH offers Vocationally-Related Qualifications (VRQs) in England, Wales and Northern

Ireland.

VRQs provide the knowledge and practical skills required for particular job roles through a

structured, study-based training programme that combines the testing of knowledge and

understanding in written examinations with practical application of learning in the workplace.

VRQs are a popular type of qualification because they are nationally recognised, flexible and

offer routes for progression to employment or further study.

In Scotland, VRQs are known as ‘Other accredited qualifications’.

1.14 Qualification progression

National Diploma holders with Environmental responsibilities may wish to take the NEBOSH

National Diploma in Environmental Management.

Learners who wish to continue their studies overseas may wish to consider the NEBOSH

International Diploma in Occupational Health and Safety. Unit DNI is a ‘common unit’ and

forms part of the National and International Diplomas. Therefore, learners who wish to study

the International Diploma will only need to pass three additional units to achieve this additional

qualification.

Learners who have achieved the NEBOSH National Diploma may be considering further

health and safety study. NEBOSH has entered into partnership with the University of Hull to

offer a range of Masters Degrees.

A number of other universities offer MSc programs which accept the NEBOSH Diploma as a

full or partial entry requirement. Some MSc courses may require additional

The Guide to the NEBOSH National Diploma in Occupational Health and Safety

(November 2015 specification)

qualifications/expertise such as a degree, further significant work experience or expect

learners to complete specific modules eg, in environmental management.

Further information can be found on our website: www.nebosh.org.uk/qualifications

1.15 Programmes offered by NEBOSH-Learning Partners

Learning Partners can be located using the ‘Where to study’ tab on our website:

www.nebosh.org.uk

NB: Learners are advised to check up-to-date information on course dates directly with

Learning Partners. It is also recommended that learners contact only Learning Partners which

appear on the NEBOSH website; this ensures that the Learning Partners have met NEBOSH’s

quality standards.

1.16 Examination dates

‘Standard’ examination dates for this qualification are available annually in January and July. Unit

DNI assignment submission dates are available annually in February, May, August and

November.

‘On-demand’ examinations are not available for this qualification.

1.17 Specification date

The November 2015 specification for this qualification replaces the previous February 2010

specification for all examinations from (and including) January 2017.

1.18 Syllabus development and review

The syllabus has been developed by NEBOSH following extensive consultation with key

stakeholders, notably previous Diploma learners, Learning Partners, professional bodies,

employers, standards setting organisations, enforcement bodies and subject experts.

NEBOSH would like to take this opportunity to thank all those who participated in the

development, piloting and implementation of this qualification.

1.19 Further information for learners

Further information for learners, including a qualification overview leaflet and examiners’

reports, can be found via the NEBOSH website (www.nebosh.org.uk).

1.20 Further information for Learning Partners

regarding the Unit DNI assignment, can be found in the Learning Partners’ section of the

NEBOSH website.

The Guide to the NEBOSH National Diploma in Occupational Health and Safety

(November 2015 specification)

2. Qualification structure

2.1 Student enrolment

• At the start of their studies, learners will enrol with NEBOSH. The enrolment period is 5-

years.

• On completion of the first successful unit, the enrolment start date will change to the same

as the declaration date (the date which appears on the unit certificate) of the successful

unit. The student will then have 5-years from this new date to achieve the qualification.

• All units will have a 5-year validity period. Units which are older than 5-years will no longer

be valid and will not count towards the qualification grading. Any such unit/s will need to

be retaken by the student to allow the student to complete the qualification.

• Once the oldest unit is no longer valid ie, it is 5 or more years older than the current date,

the enrolment start date will move to the declaration date of the second successful unit.

• The student’s enrolment period will end:

o when the student has successfully completed all 4 units; or

o when all successful units have expired (ie the declaration date/s are 5 or more years

older than the current date; or

o 5-years from the enrolment start date if the student has not attempted any unit

assessment; or

o 5-years from the enrolment start date if unit assessment/s have been attempted but

the student has received a ‘Refer’ result and/or has been marked as ‘absent’.

• If a student cannot complete all 4 units within the 5-year completion time-frame they may

apply for a unit validity extension for each affected unit. Please refer to the ‘Enrolment

Policy for NEBOSH Diploma Level Qualifications’ for further information.

2.2 Common unit and exemption

The NEBOSH National Diploma in Occupational Health and Safety shares a ‘common unit’

(Unit DNI) with the NEBOSH International Diploma in Occupational Health and Safety.

Learners can, therefore, take the assessments for Units IA, IB and IC and they will gain an

additional qualification.

The ‘common unit’ can be used as an exemption against the International Diploma in

Occupational Health and Safety for up to five years after the declaration date (the date printed

on the unit certification) of Unit DNI. Likewise, holders of the International Diploma in

Occupational Health and Safety will have five years to use their Unit DNI pass as an exemption

against the same unit for the National Diploma in Occupational Health and Safety.

2.3 Unit assessments

The National Diploma in Occupational Health and Safety is divided into four units. All units

are mandatory and there are no optional units. The student may choose to take the units

together or at different times.

The Guide to the NEBOSH National Diploma in Occupational Health and Safety

(November 2015 specification)

Unit A: Managing health and safety

• Unit A is a taught unit which is assessed by a 3-hour written examination

• The written examination consists of 11 questions split into Section A and Section B

• Section A consists of 6 ‘short-answer’ questions (10 marks each) – all questions are

compulsory

• Section B consists of 5 ‘long-answer’ questions (20 marks each) – the student answers 3

out of the 5 questions

• There is a total of 120 marks available for the paper; the total mark for the paper (Section

A + Section B) will then be converted to a percentage

• Student scripts are marked by external examiners appointed by NEBOSH

• A sample examination question paper can be found in Section 6.

Unit DNI: Application of health and safety management in the workplace

• Unit DNI consists of a written assignment set by NEBOSH

The Guide to the NEBOSH National Diploma in Occupational Health and Safety

(November 2015 specification)

• The report should be approximately 8000 words in total, excluding the references,

bibliography and appendices. No penalty will be applied to reports which exceed 8000

words but learners should aim to keep their word count under 12000

• Submission dates for Diploma assignments are in February, May, August and November

each year

• The assignment is marked by external examiners appointed by NEBOSH.

For more information on the assessment feedback provided for this qualification, please visit

the NEBOSH website: https://www.nebosh.org.uk/faqs/how-can-i-gain-feedback-on-my-

performance-to-assist-with-future/.

2.4 Assessment setting and marking

NEBOSH applies best practise in relation to assessment setting and marking. NEBOSH uses

external assessment for written examinations and assignments: scripts are sent to NEBOSH

and undergo rigorous marking, checking and results determination processes to ensure

accuracy and consistency.

2.5 Unit pass standards

The provisional pass mark for Units A, B and C is 45%. More information on how provisional

marks are set can be found in our FAQs: https://www.nebosh.org.uk/faqs/how-does-nebosh-

set-the-pass-mark-for-each-assessment/.

The pass standard for the assignment unit (Unit DNI) is 50%.

2.6 Unit certificates

Learners who are successful in an individual unit will be issued with a unit certificate, normally

within 40 working-days of the issue of the unit result notification. Units are not graded and the

unit certificates will show a ‘Pass’ only.

2.7 Qualification grade

When learners have been awarded a unit certificate for all four units (ie, have achieved a Pass

in units A, B, C and DNI), the percentage for each of the units are added together and a final

grade is awarded as follows:

Distinction 280 or more

Credit 240 – 279

Pass 185 – 239

2.8 Qualification parchment

Once a student has achieved a ‘Pass’ in all four units and the qualification grade has been

awarded they are normally considered to have completed the qualification. A qualification

parchment will be issued within 40 working days of the unit result declaration date for the fourth

successfully completed unit.

However, once the result of the fourth successfully completed unit has been issued the student

has 20 working days from the date of issue of that result to either:

The Guide to the NEBOSH National Diploma in Occupational Health and Safety

(November 2015 specification)

• Inform NEBOSH in writing of their intention to re-sit a successful unit for the purposes of

improving a grade

• Submit an Enquiry About Result (EAR) request (see Section 3.3).

2.9 Re-sitting unit/s

If a student’s performance in any unit is lower than a ‘Pass’, the student may re-sit the unit/s

in which they have been unsuccessful providing that this happens within the 5-year completion

period. However, each re-sit will incur an additional fee.

Learners may re-sit units at any time within their enrolment period and the qualification

transitional arrangements*. This includes re-sitting successful unit/s to try to improve the

qualification grade. When all four units have been successfully completed, learners will need

to inform NEBOSH of their intention to re-sit the successful unit/s within 20-working days of

the date of the results issue for the fourth unit. There is no limit to the number of re-sits

which can be taken within the enrolment period.

If a re-sit results in a lower mark than a previously declared mark for that unit, the highest mark

will be used when calculating the qualification grade.

For the Unit DNI assignment, there is no limit to the number of submissions within the

completion period. If a student gains lower than the pass standard in the assignment, they

may revise and submit the assignment again. However, they must re-register for the

assignment in order to do so. Please note that no feedback will be given on the referred

assignment and each additional submission will incur a fee. Marks awarded for subsequent

submissions will not be capped.

If a student registers for any unit of the National Diploma whilst awaiting a result from a

previous sitting of an examination that student may not seek a refund of the registration fee if

they retrospectively claim exemption for that unit except in the case of an Enquiry About

Result.

• Please refer see Section 1.1

The Guide to the NEBOSH National Diploma in Occupational Health and Safety

(November 2015 specification)

3. Policies

3.1 Requests for access arrangements/reasonable adjustments

Access arrangements and reasonable adjustments are modifications which are approved in

advance of an examination. They allow attainment to be demonstrated by learners with either

a permanent or long-term disability or learning difficulty, or temporary disability, illness or

indisposition.

Learning Partners must make requests to NEBOSH for access arrangements or reasonable

adjustments at least one month before the assessment.

For further details see the NEBOSH “Policy and procedures for access arrangements,

reasonable adjustments and special consideration” available from the NEBOSH website

(www.nebosh.org.uk).

3.2 Requests for special consideration

Special consideration is a procedure that may result in an adjustment to the marks of a student

who has been unable to demonstrate attainment because of temporary illness, injury,

indisposition or an unforeseen incident at the time of the assessment.

Learners who feel they have been disadvantaged due to illness, distraction or any other

reason during the assessment must report this to the invigilator (or the accredited course

provider in the case of the assignment) before leaving the examination room. They must

request that their written statement, together with the invigilator’s comments on the statement,

be sent by the accredited course provider to NEBOSH.

Requests for special consideration must be made to NEBOSH by the accredited course

provider as soon as possible and no more than seven working days after the assessment.

For further details see the NEBOSH “Policy and procedures on reasonable adjustments and

special consideration” available from the NEBOSH website (www.nebosh.org.uk).

3.3 Enquiries about results and appeals

NEBOSH applies detailed and thorough procedures to review and check assessment results

before they are issued. This includes a particular review of borderline results. This ensures

that the declared results are a fair and equitable reflection of the standard of performance by

learners.

There are, however, procedures for learners or Learning Partners to enquire about results that

3.4 Malpractice

Malpractice is defined as any deliberate activity, neglect, default or other practice by learners

and/or accredited course providers that compromises the integrity of the assessment process,

and/or the validity of certificates. Malpractice may include a range of issues. These include

collusion or use of unauthorised material by learners, the failure to maintain appropriate

records or systems by Learning Partners, and the deliberate falsification of records in order to

claim certificates. Failure by an accredited course provider to deal with identified issues may

in itself constitute malpractice.

4. Notes for tutors

4.1 Case studies / past incidents

The tutor references for Units A and C contain references to past incidents which were

previously part of the syllabus content. These references can be used during teaching to help

to illustrate the topic being taught. The references quoted are not an exhaustive list and tutors

are at liberty to use different incidents to those quoted in the syllabus.

The case studies/past incidents will not be examinable.

4.2 Decided cases

Decided cases are included in Units A and B and form part of the syllabus content; these

cases are, therefore, examinable. Learning Partners are only expected to give an overview

of the cases, the decision of the court and the legal precedent set in relation to health and

safety. Marks will also be awarded in assessments for other relevant case law which is applied

correctly to the scenario given.

4.3 Tutor references

Tutor references are given at the end of each unit and are split between statutory provisions

and guidance documents. These references are given to aid tutors with the teaching of the

syllabus content; they are not an exhaustive list and tutors can use other references to those

quoted in the syllabus.

4.4 Teaching of units

Although the syllabus sets out the Units and Elements in a specific order, tutors can teach the

Units and Elements in any order they feel is appropriate. Course providers will need to reflect

this in the timetables which are submitted for approval as part of the accreditation/re-

accreditation process.

Element A11 (the role of the health and safety practitioner) has been included within the

content for Unit A but will not be examinable by the Unit A written examination. The content

of this element will be assessed only through Unit DNI.

4.5 Conflict of interest

Accredited Course Provider staff including Head of Learning Partners, Tutors, Administrators,

Examinations Officers and Invigilators must declare in writing to NEBOSH any employment

and/or familial, spousal or other close personal relationship with any examination or

assessment candidate. Further information can be found in the ‘Instructions for Conducting

Regulations 2002, Regulation 7):

- design and operate processes and activities to minimise emission, release and spread

of substances hazardous to health

- take into account all relevant routes of exposure – inhalation, skin absorption and

ingestion – when developing control measures

- control exposure by measures that are proportionate to the health risk

- choose the most effective and reliable control options which minimise the escape and

spread of substances hazardous to health

- where adequate control of exposure cannot be achieved by other means, provide, in

combination with other control measures, suitable personal protective equipment

- check and review regularly all elements of control measures for their continuing

effectiveness

- inform and train all employees on the hazards and risks from the substances with which

they work and the use of control measures developed to minimise the risks

- ensure that the introduction of control measures does not increase the overall risk to

health and safety

• The control of hazardous substances with reference to the hierarchy quoted in ‘Working

with substances hazardous to health (INDG136)’:

- eliminate the use of a harmful product or substance and use a safer one

- use a safer form of the product, ie, paste rather than powder

- change the process to emit less of the substance

- enclose the process so that the product does not escape

- extract emissions of the substance near the source

- have as few employees as possible in harm’s way

- provide appropriate personal protective equipment (PPE)

and C is recommended in order to undertake the Unit DNI assignment. Learning Partners and

learners are reminded that Element A11 of Unit A will only be assessed in Unit DNI.

Assignment brief

The student is required to carry out a review of the arrangements for managing health and

safety in a workplace and to produce justified, proportionate recommendations to improve

performance.

The assignment will require the student to apply the knowledge and understanding gained

from their studies of elements of Units A, B and C in a practical environment and to carry out

critical analysis and evaluation of information gathered during the review.

The assignment should include the following.

• An introduction that sets the scene by stating clear aims and objectives and a

description of the methodology used to carry out the assignment. The introduction

should also include a description of the chosen workplace and the role of the health

and safety practitioner to set a context for the assignment.

• A critical analysis of how health and safety is currently managed by the organisation in

which the student reviews leadership, management, worker involvement, competence,

legal compliance and risk profile.

• An evaluation based on the review, of where improvements should be made.

• Conclusions which summarise the main issues identified.

• Justified, proportionate, recommendations based on the outcome of the review.

• An executive summary.

Assessment location

The Unit DNI assignment must be carried out in the student’s own workplace. Where the

student does not have access to a suitable workplace, the accredited course provider should

be consulted to help in making arrangements for the student to carry out the assignment at

suitable premises.

Learners do not require supervision when carrying out the assignment, but the student must

sign a declaration that Unit DNI is their own work.

Learners and employers should be aware that the status of the report undertaken to fulfil the

requirements of Unit DNI is for educational purposes only. It does not constitute an

assessment for the purposes of any legislation, regulations, or standards.

Submission of completed work

Assignment reports should be submitted before the set submission date; there are four

submission dates each year in February, May, August and November.

The actual dates will be published by NEBOSH annually. Learners intending to submit an

assignment must register through their accredited course provider using the appropriate form

and paying the appropriate fee. On registration learners will receive a submission form which

must accompany the assignment.

Assignments must be submitted electronically directly to NEBOSH. Learners are strongly

advised to keep a copy of their assignment report.

4 A risk assessment has identified the need to introduce a safe system of

work for cleaning some moving machinery. The system proposed would

allow the machinery to be cleaned by the operator whilst it was running at

normal speed with the guards removed. This would present a risk of

injury from the moving parts. To reduce this risk it is proposed that the

cleaning is undertaken with a long-handled device which would enable

the operator’s hands to be kept away from the moving parts.

(a) Outline the extent to which the proposed system of work meets

the ‘general principles of prevention’ referred to in Regulation 4

and Schedule 1 of the Management of Health and Safety at Work

Regulations 1999. Your answer should refer to the specific

‘general principles of prevention’ which are relevant to this

scenario. (5)

(b) Outline the steps that an organisation should take to ensure the

effective implementation of a new safe system of work, assuming

that a detailed risk assessment has already been undertaken. (5)
