Hazard Identification, Risk Assessment & Control Measures (HIRAC)

RISK MANAGEMENT

WHAT IS HAZARDS ?  ANYTHING WHICH MAY CAUSE HARM ;  Injury or ill health  To employees and others  In the workplace  The environments

 May arise from “TOOLS” or “WORK PROCESSES ”

STEP 1 : HAZARD IDENTIFICATION Review legislation & code of practices

METHODS TO IDENTIFY HAZARDS

Accident data Observe

MSDS Inspections JSA ( Job Safety Analysis) etc

RISK MANAGEMENT

CLASSIFICATION OF HAZARDS PHYSICAL

 Noise/Vibration

 Electrical

 Extreme Temperature (Heat/Cold)

 Fire/Explosion

 Radiation  Machinery/Equipment  Height/Gravitational

 Confined Space  Slip/Trip/Fall  Vehicles

 Water

RISK MANAGEMENT

CLASSIFICATION OF HAZARDS  CHEMICAL     

Very Toxic Toxic Corrosive Harmful Irritant

    

Explosive Oxidising Extremely Flammable Highly Flammable Flammable

RISK MANAGEMENT

CLASSIFICATION OF HAZARDS  BIOLOGICAL

 Animals

– Wild Dogs , Snakes, Scorpions

 Plants

- Poisons, irritants, Rashes

 Bacteria

– Legionella

 Viruses

– Influenza, HIV, Hepatitis

 Yeast

– Cryptococcus

 Fungi

– Tineas

 Parasites – Ticks, Gardia,

RISK MANAGEMENT

CLASSIFICATION OF HAZARDS  ERGONOMIC  Repetitive Work - Prolonged Similar Task  Manual Handling - Lifting, Pulling, Pushing, Twisting  Computer Works - Sitting Posture, Eyes Strain  Lighting

- Adequacy of Light

 Ventilation

- Indoor Air Quality

RISK MANAGEMENT

CLASSIFICATION OF HAZARDS  PSYCHOSOCIAL 

Shift work

- Prolonged night duty



Stress

- Multifactor



Violence

- Individual, Group



Harassment

- Sexual, Bullying

RISK MANAGEMENT

STEP 2 : ACCESSING THE RISK Gather information about each hazard identified How many people are exposed to each hazard and for how long Use the information to assess the LIKELIHOOD and CONSEQUENCES of each hazards Use a risk table to work out the RISK associated with each hazards

How LIKELY is it that a hazardous event or situation will occur ?  Very likely - frequently  Likely - Occasionally  Unlikely - happen but only rarely  Highly unlikely - happen but probably never will What might be the CONSEQUENCES of a hazardous event or situations  Fatality  Major injuries ( normally irreversible )  Minor injuries ( normally reversible requiring several days off work )  Negligible injuries ( First Aid )

RISK MANAGEMENT

Is the RISK tolerable ?  IF YES !  Leave them alone,  But need MONITORING……...

IF NO !  Need CORRECTIVE /PREVENTIVE MEASURES..

RISK MANAGEMENT

STEP 3 : CONTROLLING THE RISK LEVEL 1 : ELIMINATE THE HAZARD LEVEL 2 : MINIMISE THE RISK    

Substitute with something safer Modify the workplace ( Enclosure ) Isolate the workplace or hazardous aspect Introduce engineering control

LEVEL 3 : ‘BACK-UP’ CONTROL  

Implement administrative controls & safe work practices Require Personal Protective Equipment

RISK MANAGEMENT

STEP 4 : MONITORING AND REVIEW HOW EFFECTIVE ARE THE CONTROL MEASURES ? ANY NEW HAZARDS INTRODUCED ? HOW EFFECTIVE IS THE WORK PROCESS ? KEEP IT GOING
