OBJECTIVES:
TO HAVE A CLEAR IDEA ON HAZARD
IDENTIFICATION, RISK ASSESSMENT &
RISK CONTROL
TO UNDERSTAND THE METHODOLOGY TO
PERFORM GROUP RISK ASSESSMENT
TO ADOPT CONTROL MEASURES TO
MINIMISE SIGNIFICANT RISKS
4.3.1 Planning for Hazard Identification, Risk Assessment & Risk Control
2
4.3.1 Planning for Hazard Identification, Risk Assessment & Risk Control
• Hazard is a source or situation with a potential for
harm in terms of human injury or ill health, damage to property, damage to the workplace environment or a combination of these.
• Hazard Identification
is a process of recognizing that a hazard exists and defining its characteristics
3
4.3.1 Planning for Hazard Identification, Risk Assessment & Risk Control
Intent of the Clause 4.3.1
This processes of hazard identification, risk assessment, risk control help the organization to identify, evaluate and control its OH&S risks on an ongoing basis.
4
People (P)Equipment (E)MaterialEnvironment
OH&S Risks
The elements which are exposed to OH&S hazards are:
5
More specifically the risks to these elements have been further broken-down as follows.
People : Occupational Health (OH)Occupational Safety (OS)
Equipment/: Equipment Damage (ED)Property Property Damage (PD)
OH&S Risks
6
Occupational Health: Condition or factors that affect the well being of
human health (employees, temporary workers, contractor personnel and other) during work, in particular and in a working environment, in general.
The aspects that are primarily included affecting human health (which is NOT merely physical health but mental health also) are artificial humidification, drinking water, dust & fume, latrines, lighting, overcrowding, spittoons etc.
OH&S Risks
7
Occupational Safety :
It deals with the control of accidental loss
during work . Here the term occupational safety
primarily deals with human content
OH&S Risks
8
More specifically the word illness and injury are used frequently for Occupational Health and Occupational Safety respectively
But Occupational Health & Occupational Safety should also consider damage to other things such as properties and equipment
OH&S Risks

Illness which ultimately cause loss of life or permanent damage to body organ viz. loss of hearing, chronic diseases due to exposure to hazardous pollutants etc.

upto 1 hour or repair costs
typically upto Rs.0.5 Lakh
Rating Scale for Equipment

SEVERITY (IMPACT)
4 Extreme Risks - Unacceptable risk level. Actions required to eliminate or reduce this risk level immediately
3 High Risks - Extensive actions are required to control this risk level
2 Moderate Risks - Appropriate controls are required
1 Low Risks - Control may still be justified
18
The whole process of Hazard identification, risk assessment and risk control shall be done under all the three conditions viz :
Normal operating conditions
Abnormal operating conditions
Emergency conditions
OH&S Risks
19
The Control of significant OH&S risks involves three possible alternatives viz.
Termination Treatment Tolerance
Control of Significant OH&S Risks
20
Termination: Termination of the OHS risks by
such actions, that they cease to exist. Usually
these are specific actions that can be completed
in short term.
Examples are eliminating water circulation
for RHF, providing a platform in place of
portable ladder.
Control of Significant OH&S Risks
21
Treatment :Improvement in OHS performance can
be achieved through treatment of significant OHS
risks of different activities. Specific projects shall
be undertaken for performance improvement.
Examples are Provision of bund wall in converter
to protect the cables (property damage) in case of
spillage of hot metal, Modifying the acid loading
method to avoid exposure of personnel to acid.
Control of Significant OH&S Risks
22
Tolerance: Some of the OHS risks may not be so easily amenable for performance improvements or the present resources do not permit undertaking of improvement (Management) programmes immediately. In such an event it may be necessary to tolerate the actions. However such activities shall be carried out in a prescribed manner to contain and maintain present level of performance.Examples are exposed cable trays, unguarded ceiling fans etc.
