The recent Management of Health and Safety at Work Regulations, published in 1992, also refer to the need to have in place management arrangements for health and safety.
The recognition of the importance of safety management is not a new concept. For example, the Roben’s Report in 1972 stated that the promotion of health and safety at work is an essential function of good management.

Why are they important?
The application of scientific information
concerning humans to the design of objects,
systems and environment for human use.
The interaction of technology and people
Basic anatomy, physiology and psychology
Objective to achieve:
The most productive use of human capabilities
Maintenance of human health and well-being

The job must ‘fit the person’ and should not
compromise human capabilities and limitations.
Physical demands - musculoskeletal disorders
Psychological demands - stress
Social conditions - job satisfaction
Human error - cause of major accidents.

Health & Safety at Work
Regulations (MHSWR, 1992)
“Every employer shall make and give effect to
such arrangements as are appropriate, having
regard to the nature of his activities and the size
of his undertaking, for the effective planning,
organisation, control, monitoring and review of
the preventative and protective measures”
Robens Report, 1972
“Promotion of health and safety at work is an
essential function of good management … Good
intentions at the board level are useless if
managers further down the chain and closer to
what happens on the shop floor remain
preoccupied exclusively with production
Industrial Accident Prevention
“Underlying accident causes are faults of
management and supervision plus the unwise
methods and procedures that management and
supervision fail to correct…”
Tends to be more concerned with
Personal safety accidents
Failures of people at the sharp end
The premise is that people are free to choose
the actions they make
Human factors is based on the principle that
people are ‘set up’ to fail
