DETERMINING SEVERITY
The degree of injury, illness, or damage to property, environment, or reputation, which is reasonably predictable. Severity in terms of: Harm to health Damage to property Damage to environment Or the combination of the above3

DETERMINING LIKELIHOOD OF OCCURRENCE OF HAZARDProbability or Likelihood, is defined as: the chance that a given event will occur. Probability is often based on historical data frequency of reported incidences; However : Just because no accident has happened for a long time does not mean it cannot happen tomorrow; CIMAH cases Just because it has happened recently does not mean that it will happen again soon; Adequacy of controls
Based on statistic & data, professional

QUANTITATIVE RISK ASSESSMENT
Where the hazards presented by the undertaking are numerous and complex, and may involve novel processes, for example in the case of large chemicals process plants, detailed and sophisticated risk assessments will be needed, and it is appropriate to carry out a detailed quantitative risk assessment.11

QUANTITATIVE RISK ASSESSMENT
Quantitative risk assessment involves obtaining a numerical estimate of the risk from a quantitative consideration of event probabilities and consequences

QUANTITATIVE RISK ASSESSMENT
In carrying out quantitative risk assessments, special quantitative tools and techniques will be used for hazard identification, and to estimate the severity of the consequences and the likelihood of realization of the hazards

SUBSTITUTION USING A LESS HAZARDOUS MATERIAL OR PROCESS, SUCH AS USING MECHANICAL DEVICES INSTEAD OF MANUAL HANDLING 3. ISOLATION ISOLATING NOISY COMPRESSORS FROM WORKERS AREA ENCLOSURE, DISTANCE GUARD 4. ENGINEERING CONTROL MODIFICATION OR RETROFIT LOCAL EXHAUST VENTILATION GUARD FOR ROTATING MACHINERY 5. ADMINISTRATIVE CONTROL PROCEDURE : ROTATION OF WORKERS REDUCING PERIOD OF EXPOSURE REDUCING NUMBER OF WORKERS EXPOSED 6.

THE NEED FOR JHA
JHA is a tool to carefully study each job or task, and come out with a Safe Operating Procedure A PTW should only be issued after JHA has been carried out In JHA, HIRARC is carried out for all the steps of the task identified; here, all possible hazards related to every step of the task is identified, and then adequately controlled.39

THE NEED FOR HIRARC
HIRARC is a proactive means of identifying and eliminating hazards, and provides an acceptable standard of safety Legal Requirement : Ensure Safe Place of Work Corporate Image : Public/Customer Confidence Moral/Ethical Consideration : Limit Worker Injuries Loss Control : Prevent Accidents / Incidents Especially When Revenue Is Maximum And Expenses Are On The Rise, Survival Mode Is Triggered Cut Down On Avoidable Losses!

JHA vs HIRARC
JHA : STUDIES THE JOB IN THIS CASE INSTALLING THE KERB BREAKS DOWN THE JOB INTO STEPS DO HIRARC FOR EVERY STEP
HIRARC : OVERSEES ALL THE HAZARDS IN THE AREA OF CONCERN VEHICLES, POTHOLES, TREE BRANCHES, POWER LINES, DRAINS A POINT IN TIME
RISK ASSESSMENT IS REQUIRED IN HIRARC42

JHA vs HIRARC
Section 15 (2)(a) of the OSHA 12614:the provision and maintenance of plant (HIRARC) and systems of work (JHA) that are, so far as is practicable, safe and without risks to health
HIRARC Hazard Identification, Risk Assessment and Risk Control are three principles used in workplaces to manage safety and health. Requirement under Management Systems ISO 9000, ISO 14000, OHSAS 1800043

SAMPLE OF A JHATARGET : MOVE THE LOAD SAFELY
LIFTING LOAD USING MOBILE CRANE :1. 2. 3. 4. 5. 6. 7. 8. 9.
Move the crane to position Extend the outriggers Extend boom and slew so that hook is directly above load Attach load to hook Lift the load Move the load to desired location If you miss one process, Put down the load will you meet the target? Retract boom, and If target is not achieved, Retract the outriggers which process could bethe culprit?
Precautions before and after.

GROUND IS SOFT 2.3. HYDRAULIC SYSTEM FAILS 3 EXTEND BOOM TO HOVER ABOVE THE LOAD 4 USE SLINGS TO ATTACH LOAD TO THE HOOK 3.1. BOOM IS EXTENDED TOO LONG 4.1. SLINGS ARE UNDER CAPACITY 4.2. SLINGS ARE DAMAGED: KINKED, FRAYED 4.3. HAND GETS ENTANGLED BY SLINGS RISK - WHAT CAN HAPPEN INCONVENIENCE, ACCIDENT INVOLVING OTHER TRAFFIC CRANE MAY TOPPLE WHEN LIFTING CRANE MAY TOPPLE WHEN LIFTING ONE OUTRIGGER MAY RETRACT, CAUSING CRANE IMBALANCE MAY HIT ADJACENT STRUCTURES, POWER LINE SLINGS MAY BREAK.

HAZARDS WHAT IF ... 5.1. LOAD IS NOT EXACTLY BELOW BOOM 6.1. PEOPLE ARE WORKING UNDER PATH OF LOAD 6.2. PEOPLE ARE STANDING TOO NEAR THE CRANE 6.3. LOAD SLIPS THROUGH THE SLINGS 6.4. MOMENTUM DESTABILIZES THE CRANE
RISKS - WHAT CAN HAPPEN LOAD MAY SWING, CAN TOPPLE CRANE LOAD MAY FALL ON PEOPLE PEOPLE MAY BE HIT BY THE CRANE AS IT TURNS LOAD MAY FALL
DAMAGE OR INJURY TO OPERATOR, CRANE, LOAD, RIGGER LOAD, OTHERS
CONTROL MEASURES ENSURE BOOM IS VERTICAL, USE TAG LINES TO CONTROL LOAD CLEAR ALL PEOPLE IN ITS PATH; CLEAR ALL PEOPLE AROUND THE ACTIVE RADIUS OF CRANE; PUT UP BARRICADES, SIGNAGE USE SPACER BARS ON SLINGS, TIE SLINGS SECURELY TO LOAD CONTROL SLEWING MOTION. CARRY OUT SLEWING SLOWLY LOWER THE LOAD ONTO TO A PALLET TRAINING, REMINDERS

PRECAUTIONS :A. B. C. D. DO NOT EXTEND BOOM OR CARRY A LOAD BEFORE EXTENDING THE OUTRIGGERS DO NOT RETRACT THE OUTRIGGERS BEFORE RETRACTING THE BOOM DO NOT LIFT OVER PEOPLE DO NOT LEAVE A CRANE WITH THE BOOM EXTENDED, UNATTENDED

JOB RISK ANALYSISJOB : Transferring pipes using an overhead craneJob Description Hazard Statement Possible Consequences Controls required
Supervisor watching pipes being moved while standing beneath the load
The sling maybe under capacityThe sling is not rigged properly A forklift is moving in that area The supervisor is standing beneath the pipes
Sling may break, and pipes can fall. The pipes can come loose and fall. People under it can be injured or killed.Forklift can knock the pipes down. Supervisor may not have time to escape Supervisor can be fatally injured
Confirm rope capacity Do rope inspectionProvide training on proper rigging and slinging techniques Forklift driver should ensure clear path before moving Stay clear of hanging loads; Crane operators should be warned never to carry loads over people
Start by identifying all the Hazards first, to ensure continuous line of thought49
