Safety engineering model

- A well-known early study into safety management was undertaken by an

American engineer H.W Henrich in 1931 and is usually refers to as

Henrichs dominion theory

- He identies chain of e!ents and circumstances that ultimately lead toin"ury#1. $n!ironmental factors%. &ault of the indi!idual3. 'nsafe act or condition(. Accident). *gnorant- Henrich analyse a number of accidents and determine that ++, were due

unsafe acts and 1, due to unsafe conditions- hese ndings has formed a base of much subse/uent 0SH .- A similar nding emerged from a de!elo2ment of the safety engineering

model S$45

- *n this model de!elo2ed in the united states of America6 research conrmsthe similar balance of unsafe acts +),5 and unsafe conditions 1),5

- 7esearchers further suggested that unsafe acts are best educated through

education and enforcement whereas unsafe conditions are best 2re!ent

through im2ro!ed engineering 2ractices and enforcement of these

2ractices- he addition of management and worker beha!iour to the basic model

include a focus on the following elements#1. $m2owerment of workers%. Ado2tion of 2rogressi!e labour 2ractices3. 8romotion of health and safety as a 2ersonal and organisational !alue

(. e!elo2ment of 2ositi!e worker attitude to focus on beha!iourmodication

). A22lication of ergonomic and human factor analysis- *n addition a focus of healthy in the work2lace was introduced6 this

introduced an em2hasis on 2rotecting and 2romoting healthy and safety in

the work 2lace- :ey as2ects included#

1. 8re!ention and control of occu2ational diseases and accidents%. e!elo2ment and 2romotion of healthy and safe work 2lace3. $nhancement of 2hysical and mental of social well-being of em2loyees(. $m2owerment of em2loyees to conduct social and economically

2roducti!e li!es- hese early studies and de!elo2ments created a 2latform for the

emergence of more systematic a22roach to 0SH in the work 2lace

assessment and then selecting ha?ards controls is an im2ortant 2art of the

management of healthy and safety at work
