AIM OF THIS SESSION Is to equip all participants with
the know-how of JSA & RA Is to assist SHU in the above
processes and to guide other staff in carrying out JSA & RA

Part IJSA
JOB SAFETY ANALYSIS
JSA- technique to indentify all steps in the job & accident prevention measures
Two types of JSAJSA- can be : job base (lab tech)
: activity base (using a fume hood)
STAGES IN JSAInitial JSA
Total JSA
INITIAL JSA The following information is required:1. job title2. department or section 3. job operations ( stage by stage break
down of mental and physical task)4. machinery & equipment used5. material used 6. protection needed7. the hazard encountered8. degree of risk involved9. work organisation including
responsibilities of each
TOTAL JSA From the initial stage proceed to TJSA to examine the following:
1. operations2. hazards3. skill required-
knowledge,behavoiur
TOTAL JSA
4. external influence on behaviour: nature of influences, e.g.
noise Source of influences, e.g.
machinery activities, e.g. loading
5. learning method
SAMPLESJSA/RA form-to be distributed
Part II- Risk Assessment
& Management
WHAT IS RISK ASSESSMENT
Def: Involves identification of hazards-
in activities or layout of premises
evaluating the extent of risk
taking into account of precaution already present
WHY RISK ASSESSMENT To be in compliance with section 10 & 11 of Occupational Safety and Health Act 2005
Give some more reasons:
EXPLANATION OF TERMS ACOP states:
hazard-something with potential to cause harm;
risk-express likelihood that harm from a particular hazard
might realised ; extent of risk- covers population which might be affected by risk.
THE RISK ASSESSMENT PROCEDURE
Evaluate the Risk
Decide on control measures
Record all findings
Hazard Identification
Identify people at risk
IDENTIFICATION OF HAZARDS Mechanical hazards: e.g. injury by
moving parts. Physical hazards: slipping on a wet
floor or tripping on uneven flooring or trailing wires.
Chemical hazards: spillage of corrosive acid which can severely damage skin and eyes through contact.
Environmental hazards: in the global environment water can be polluted by chemicals and or by toxic waste.
IDENTIFICATION OF HAZARDSBiological hazards: this includes bacteria and micro-organisms of the type encountered
Organisational hazards include: working with unreasonable timescales or excessive workloads; using an unsafe way of working where instructions are not provided or not followed
QUANTIFYING THE RISKS(RISK EVALUATION)
Range Formula Risk Rating =
Probability (P)x Severity (S)x
Frequency (F) Range from 1-1000
QUANTIFYING THE RISKS Risk Priority of action in respect of
Range Action required
Below 200 No immediate action keep under review
200-400 Within next year
400- 600 Within next 3 month
600-800 With next month
800-1000 Immediate/prohibition of use
QUANTIFYING THE RISKS(PROBABILITY INDEX)
Probability index Descriptive phase
10 Inevitable
9 Almost certain
8 Very likely
7 Probable
6 More than even chance
5 Even chance
4Less than even chance
QUANTIFYING THE RISKS(PROBABILITY INDEX)
Probability index Descriptive phase
3 Improbable
2 Very improbable
1 Almost impossible
QUANTIFYING THE RISKS (SEVERITY INDEX)
Severity index Description phrase
10 Death
9 Permanent total incapability
8 Permanent severe incapability
7 Permanent slight incapability
6 Absent for more than 3 weeks with a recurrence of incapability
5 Absent from work for more than 3 weeks but with subsequent complete recovery
4 Absent from work for more than 3 days but less than 3 weeks with subsequent recovery
QUANTIFYING THE RISKS(SEVERITY INDEX)
Severity index Description phrase
3 Absent form work for less than 3 days with complete recovery
2 Minor injury with no lost time and complete recovery
1 No human injury
QUANTIFYING THE RISKS(FREQUENCY INDEX)
Frequency Descriptive phase
10 Hazard permanently present
9 Hazard arises every 30 seconds
8 Hazard arises every minutes
7 Hazard arises every 30 minutes
6 Hazard arises every hour
5 Hazard arises every shift
4 Hazard arises once a week
QUANTIFYING THE RISKS(FREQUENCY INDEX)
Frequency Descriptive phrase 3 Hazard arises once a
month
2 Hazard arises every year
1 Hazard arises every five year
MANAGEMENT OF RISK
You are expert in your fields so manage the risks and make your
workplace safer and healthier.
A safer and healthier workplace might lead to increase in
productive and performance.
