RISK ASSESSMENTS (GENERAL) POLICY AND GUIDANCE
It is the policy of the University that a risk assessment is carried out in respect to all
activities, processes and substances and that it is regularly reviewed and documented
where necessary. This responsibility rests with Deans/Directors/Heads as stated in the
University’s Health & Safety Policy and Organisation document (revised 2010).
Deans/Directors/Heads should also nominate competent staff to carry out these
assessments.
LEGAL FRAMEWORK
The University has a responsibility under S2 and 3 of the Health & Safety at Work Act 1974
to ensure, so far as is reasonably practicable, the health and safety of employees and other
persons (students, visitors, contractors, etc.) who may be affected by the work activity. The
Management of Health & Safety at Work Regulations 1992 further amplify this duty and
impose a specific requirement upon the University to carry out a ‘suitable and sufficient’
assessment of all risks to the health and safety of employees and others arising at or from a
work activity. Furthermore, all modern legislation now contains a duty to carry out risk
assessments for specific types of hazards such as those associated with substances,
electricity, noise, manual handling, VDU work, etc. The purpose of this document,
therefore, is to:
(a)
Provide guidance to enable Schools/Services to comply with risk assessment duties as
required by relevant law.
(b)
Introduce a structured, systematic and pro-active approach to the management of
risk.
(c)
Outline the five principal steps to risk assessment.
DEFINITIONS
RISK ASSESSMENT: A structured and systematic procedure for identifying hazards and
evaluating risks in order to prioritise decisions to reduce risks to an acceptable level.
HAZARD: Something with the inherent ‘potential to cause harm’.
substances, machines, methods of work or work organisation.
This can include
RISK: Is the chance, great or small, that someone will be harmed by the hazard. The
magnitude/scale of the risk is measured in terms of its consequences, frequency and
severity. It can be expressed as:
RISK  HAZARD SEVERITY X LIKELIHOOD/PROBABILITY OF OCCURRENCE
HAZARD AND RISK : TWO EXAMPLES
Two men are five metres up identical ladders. The hazard of falling off is the same for both
men. However, Bill’s ladder is secured, while Ted’s is not. Ted’s risk of falling is, therefore,
higher. Worse yet, Ted’s ladder is jutting out into the gangway where the forklifts go by!
3
 Take a drum of MEK solvent. MEK is flammable and harmful to health. The drum is
sealed and sitting in a flammable liquids store, so while the hazards are there, the risk of
harm is much less than when the drum is opened and an operator pours some into a
container. If the operator pours it without using gloves or goggles, the risk is even
greater. If he pours it out more than once, it is greater still.
The examples demonstrate that if precautions/safeguards are built into the work activity
the risk of harm is reduced and, in consequence, the potential severity of any injury.
COMPETENCY
Assessments should be conducted by competent staff nominated by
Deans/Directors/Heads. Assessors should have an understanding of the workplace, an
ability to make sound judgements and knowledge of the best ways to reduce those risks
identified. Competency does not require a particular level of qualification but may be
defined as a combination of knowledge, skills, experience and personal qualities, including
the ability to recognise the extent and limitation of one’s own competence.
SUITABLE AND SUFFICIENT ASSESSMENT
A ‘suitable and sufficient assessment’ as required by the Management of Health and Safety
at Work Regulations 1992 is one that:
 Correctly and accurately identifies a hazard.
 Disregards inconsequential risks and those risks associated with life in general.
 Determines the likelihood of injury or harm arising.
 Quantifies the severity of the consequences and the numbers of people who would be
affected.
 Takes into account any existing control measures.
 Identifies any specific legal duty or requirement relating to the hazard.
 Will remain valid for a reasonable period of time.
 Provides sufficient information to enable the Dean/Director/Head to decide upon
appropriate control measures, taking into account the latest scientific developments and
advances.
 Enables the School/Service to prioritise remedial measures.
If an assessment has already been carried out under any other statutory provision, e.g.
Manual Handling Operations Regulations, COSHH, Noise at Work Regulations, etc. no
duplicate action is necessary as a result of this document.

CARRYING OUT THE ASSESSMENT
Step 1 :
Look For The Hazards
This necessitates an inspection of the workplace to identify what could reasonably be
expected to cause harm. Ignore the trivial and concentrate only on significant hazards
which could result in serious harm or affect several people. Involve both staff and students
in this exercise because they may be aware of hazards which are not immediately obvious.
Manufacturers’ instructions, data sheets, check lists and accident records will assist in
identifying hazards.
Step 2 :
Decide Who Might be Harmed and How
Take into account staff, students, contractors and members of the public in general as well
as those people who may not be in the workplace all the time, e.g. cleaners and
maintenance personnel. Consider how such people may be harmed. Pay particular
attention to lone workers and those with disabilities since they may be more vulnerable.
Step 3 :
Assess The Risks
Evaluate the risks arising from the hazards and decide whether existing precautions are
adequate or more should be done.
Even after all precautions have been taken, usually some risks remain. Decide for each
significant hazard whether this remaining risk is acceptable. Consider whether the existing
precautions:
 Meet the standards set by legal requirement
 Comply with a recognised industry standard.
 Represent good practice.
 Reduce risk as far as is reasonably practicable.
If the answer to any of the above is ‘NO’ then consider what further precautions can be
taken to control the risk so that harm is unlikely (see hazard/risk control page 6/7).
Step 4 :
Record Assessment Findings
An assessment should be supported by accurate record keeping unless the identified risk is
trivial and the likelihood of injury is remote or that the adverse consequences would result
in a very minor injury. The significant risks only, therefore, need to be recorded. Records
should contain at least the following information:
 A description of the process/activity assessed
 Identification of the significant risks.
5
 Identification of any staff/student/visitors at particular risk.
 Date of assessment and, where appropriate, next review.
 The name of the person carrying out the assessment.
An example of a widely used risk assessment record form is provided in appendix 2; however, any
format can be used provided it follows the principles laid down in this policy.
Step 5 :
Assessment Review
An assessment must be kept up to date and reviewed periodically to ensure that it remains valid.
Factors that may necessitate an automatic re-assessment include:

A change in legislation.

A change in control measures.

Any significant change in the work carried out.

Transfer to new technology.

Any other reason to suspect that the original assessment is no longer valid or could be
improved.
HAZARD/RISK CONTROL
The selection and implementation of the most appropriate method of risk or hazard control is
crucial to any success in reducing the risk of injury or ill health to persons affected by work activities.
A hierarchy of control options are listed but it may be necessary to implement a number of these
measures in combination to adequately reduce the risk. The list is not exhaustive:

Elimination (e.g. buying ready sawn timber rather than use a circular saw).

Substitution by something less hazardous.

Total enclosure (enclose it in a way that eliminates or controls the hazard, i.e. processing
hazardous substances in an enclosed piped system).

Partial enclosure. The use of LEV systems, fume cupboards, etc.

Guarding/segregation of people.

Permit to work systems e.g. Hot work permit to control fire risks.

Reduce the period of exposure.

Written procedures that are known and understood by those affected.

Adequate supervision.
6

Adequate training/staff and students.

Information/instruction (signs, labels, handouts).

Personal protective equipment PPE
The use of PPE should be regarded as a last resort option in the absence of any more reliable or
permanent means of control.
All these measures should be considered within the overall context of achieving ‘a safe system of
work’ that reduces the risk to an acceptable level.
EVALUATING THE RISK AND SETTING PRIORITIES
The risk assessment should enable Schools/Services to prioritise remedial measures. In many cases
it will be clear that some risks require attention before others. Where there is uncertainty a risk
rating may be attributed to each identified hazard. The factors relating to severity and likelihood of
harm are given a numerical value and then multiplied together to give a risk rating which can then
be used to prioritise remedial actions.

For the purpose of risk evaluation the matrix shown above can be used to provide an initial
breakdown of the hazards into categories, follows:

Hazards with risk ratings in the unshaded area can usually be considered as trivial.
7

Hazards with risk ratings in the shaded area below the lower double line can be considered as
adequately controlled risk.

Hazards with risk ratings above the upper double line must be considered as not adequately
controlled - further controls will be required.

Hazards with risk ratings in the darker shaded areas above the upper double line will require
consideration of whether to suspend the activity until controls are introduced.

The control measures provided for hazards with risk ratings between the two double lines must
be examined against current standards and good practice to arrive at a decision as to whether
the hazard is adequately controlled or not adequately controlled.
SEVERITY OF INJURY AND ILL HEALTH DEFINITIONS
Description

Loss Time Injury

Example
Bruising, light abrasion, etc. ‘first aid’
Burns/scalds/cuts - up to 3 days off work
More than 3 days off work – reportable under RIDDOR 1995
Serious injury/damage to health, permanent disability, loss of sight,
amputation, etc. reportable under RIDDOR 1995
It is important to note that analysing the likelihood and severity of harm is not the ‘be-all and endall’ of risk assessment. The analysis is only a systematic way of ensuring that likelihood and severity
are considered. Neither is the system illustrated above the only way of rating risk; it has been used
purely as an example.
It should be remembered that accidents and ill health cost money, whilst safety, properly
managed, saves money.

NB: THE SEVERITY X LIKELIHOOD RATINGS ARE CALCULATED AFTER TAKING INTO ACCOUNT EXISTING PRECAUTIONS.
NNB: The examples above show that it is quite possible to have a high hazard (circular saw) with a potential for serious injury but the actual risk of injury
itself is low because of the precautions taken. On the other hand it is possible to have a relatively low hazard (trailing cable in office) but the risk of injury
is quite high because no precautions to prevent the tripping hazard have been taken.
