SAFETY ?
Answer is :by adopting
Risk Management
Risk Management study
Recommended by :9th Conference on Safety in mines
New Delhi 2nd & 3rd Feb. 2000.
DGMS (Tech) (S&T) Circular No.13 of 2002
Dt 31.12.2002
Why Risk Management
is Needed ?
1. Accident in Indian Mines are not in reducing trend since a long
period ( Say last 20 Yrs approx.)
2. Statutory provisions can never be fully comprehensive,
appropriate and site specific.
3. Process of Legislation Making, is often slow, these often trail
behind the technological innovations.
4. To make, the statutory provisions, ‘Flexible’ by switching
over from the regime of ‘Prescriptive Regulation ’ to ‘Self
Regulatory’ or ‘Goal Setting Legislation’.
Risk Management
Risk Management
is the process
to eliminate / reduce
Hazards
that may take place
to an
acceptable / desired level.
• Hazard : Source of potential harm,
injury or loss.
• Risk : Combination of the likelihood
of a specific unwanted event and the
potential consequences if it should
occur.
Hazard
A live tiger is always a hazard.
 A live tiger has the potential to cause you
harm and is, therefore, always a hazard.

RISK
• Tiger is always a hazard
• Loose tiger is a risk
• Risk is measured in
terms of Chance & Effect
Severity (Consequence)
Likelihood ( Chance )
Is it possible for all ?
Risk
The Chance of something happening that will
an impact on objectives.
It is measured in consequences and
likelihood.
Risk
= Consequence
X Exposure
X
Probability
Consequence
It is the outcome of an event or situation.
In terms of health and safety, it is the
degree of harm that could be caused to
people exposed to the hazards
