OSH-MS (MS 1722:2003)
• Policy
• Organizing
• Planning And Implementation
• Measuring Performance
• Action for Improvement
Key Elements
![Page 5: HAZARD IDENTIFICATION, RISK ASSESSMENT & RISK CONTROL€¦ · 07/06/2017 · Introduction to HIRARC •Principles used in workplace to manage safety and health. •Section 15 (2)(a)](https://reader034.vdocuments.mx/reader034/viewer/2022052306/609210b69e95070084343518/html5/thumbnails/5.jpg)
Why We Need OSH-MS
• Our Organization to be No. 1
• Increase “Return of Investment”
- employees, money , time…..
• Safe work place
![Page 6: HAZARD IDENTIFICATION, RISK ASSESSMENT & RISK CONTROL€¦ · 07/06/2017 · Introduction to HIRARC •Principles used in workplace to manage safety and health. •Section 15 (2)(a)](https://reader034.vdocuments.mx/reader034/viewer/2022052306/609210b69e95070084343518/html5/thumbnails/6.jpg)
How To Start
• Organization should have vision
• Commitment from management
- right people
- resource
- time
![Page 7: HAZARD IDENTIFICATION, RISK ASSESSMENT & RISK CONTROL€¦ · 07/06/2017 · Introduction to HIRARC •Principles used in workplace to manage safety and health. •Section 15 (2)(a)](https://reader034.vdocuments.mx/reader034/viewer/2022052306/609210b69e95070084343518/html5/thumbnails/7.jpg)
• Should have internal audit
• Management committee to review reports
• External audit
• Specific organization policy- hazard specific
• Employee’s participation - meeting, training
• Safety as basic training
How To Start
![Page 8: HAZARD IDENTIFICATION, RISK ASSESSMENT & RISK CONTROL€¦ · 07/06/2017 · Introduction to HIRARC •Principles used in workplace to manage safety and health. •Section 15 (2)(a)](https://reader034.vdocuments.mx/reader034/viewer/2022052306/609210b69e95070084343518/html5/thumbnails/8.jpg)
Why conduct a risk assessment
• Human factors–save life, stop workplace injures, illnesses and increase staff morale.
• Legal factors–meet legislative requirements, OHS&W and WorkCover.
• Financial factors–decrease the risk of prosecution and fines incurred, lower WorkCoverlevies, reduce absenteeism, increase potential for gaining shareholders and increase productivity.

Hazard Management Process • Identify the hazards
• Assess the risks
• Evaluate risks
• Control the risks
• Monitor and review

Introduction to HIRARC
• Principles used in workplace to manage safety and health.
• Section 15 (2)(a) of OSHA 1994:
which reads “ the provision and maintenance of plants and systems of work that are,so far as is practicable, safe and without risks to health”
![Page 11: HAZARD IDENTIFICATION, RISK ASSESSMENT & RISK CONTROL€¦ · 07/06/2017 · Introduction to HIRARC •Principles used in workplace to manage safety and health. •Section 15 (2)(a)](https://reader034.vdocuments.mx/reader034/viewer/2022052306/609210b69e95070084343518/html5/thumbnails/11.jpg)
Definition • Hazard
A source or a situation with a potential for harm to humans, property and damage of environment or a combination of these.
• Danger
Relative exposure to hazard.
• Risk
A combination of likelihood of occurrence and severity of injury or damage.

Hazard Identification
• To keep workplace safe and healthy.
-employers should make sure there are no hazards to which employees could be exposed.
• Employers should look for hazards in advance
as part of their risk management plan to prevent potential hazards.
![Page 21: HAZARD IDENTIFICATION, RISK ASSESSMENT & RISK CONTROL€¦ · 07/06/2017 · Introduction to HIRARC •Principles used in workplace to manage safety and health. •Section 15 (2)(a)](https://reader034.vdocuments.mx/reader034/viewer/2022052306/609210b69e95070084343518/html5/thumbnails/21.jpg)
Actions & Recommendations

- Semi-quantitative
- Quantitative
![Page 23: HAZARD IDENTIFICATION, RISK ASSESSMENT & RISK CONTROL€¦ · 07/06/2017 · Introduction to HIRARC •Principles used in workplace to manage safety and health. •Section 15 (2)(a)](https://reader034.vdocuments.mx/reader034/viewer/2022052306/609210b69e95070084343518/html5/thumbnails/23.jpg)
How To Assess Risk
1) Look for the Hazards
2) Decide who might be harmed & how
3) Evaluate the risk and check what is
done to prevent it from happening
• 4) Record finding
• 5) Review assessment and revise it if necessary

Quantitative Risk Assessment
• In cases where hazards are numerous and complex
eg; Chemical process plant
Should have Job Safety Analysis (JSA)
- describe job in less than 10 steps
- List things that can go wrong
- eg; Changing a Car Wheel

Actions & Recommendations
• EL- Eliminate
• SL- Substitute
• IS- Isolation
• EC- Engineering Control
• AC - Administration Control
• PPE- Personal Protection Equipment
![Page 32: HAZARD IDENTIFICATION, RISK ASSESSMENT & RISK CONTROL€¦ · 07/06/2017 · Introduction to HIRARC •Principles used in workplace to manage safety and health. •Section 15 (2)(a)](https://reader034.vdocuments.mx/reader034/viewer/2022052306/609210b69e95070084343518/html5/thumbnails/32.jpg)
Actions & Recommendations
Eg;
EL - stop work, cover hazard…
SL - use other route, other material..
IS - put up temporary barrier,…
EC - construct permanent wall,..
AC - put up notice, job rotation,…
PPE - gloves, respirator,……
