JOB SAFETY ANALYSIS
JSA- technique to indentify all steps in the job & accident prevention measures
![Page 6: Job Safety Analysis & Risk Assessment](https://reader036.vdocuments.us/reader036/viewer/2022062223/552593624a79598a498b4b5f/html5/thumbnails/6.jpg)
Two types of JSAJSA- can be : job base (lab tech)
: activity base (using a fume hood)

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:

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
![Page 14: Job Safety Analysis & Risk Assessment](https://reader036.vdocuments.us/reader036/viewer/2022062223/552593624a79598a498b4b5f/html5/thumbnails/14.jpg)
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
