Principles of
Safety Management
An unsafe act, an unsafe condition, anaccident; all these are symptoms of
something wrong in the management
system.
PRINCIPLE : 1
8/10/2019 1 Principles of Accident Prevention
15/52
Principles of
Safety Management
Certain sets of circumstances can be
predicted to produce severe injuries. These
circumstances can be identified and
controlled:
PRINCIPLE : 2
Unusual, non-routine
Nonproductive activities
High energy sources, certain
construction situations
8/10/2019 1 Principles of Accident Prevention

Principles of
Safety Management
Safety should be managed like any other
company function.
Management should direct the safety effort
by setting achievable goals, by planning,
organising and controlling to achieve them.
PRINCIPLE : 3
8/10/2019 1 Principles of Accident Prevention

The key to effective line safetyperformance is management
procedures that fix accountability.
PRINCIPLE : 4
8/10/2019 1 Principles of Accident Prevention
18/52
Principles of
Safety Management
The function of safety is to locate and
define the operational errors that allow
accidents to occur. This function can be
carried out in two ways:
PRINCIPLE : 5
1. by asking why - searching for root causes of accidents, and
2. by asking whether or not certain known effective controls are
being utilized.
