Heinrich’s Principles Of Industrial Safety
The occurrence of an injury invariably results from a completed sequence of factors, the last one of these being the accident itself. The accident in turn is invariably caused or permitted directly by the unsafe act of a person and/or a mechanical or physical hazard.
The persons unsafe acts are responsible for majority of accidents.
The person who suffers a disabling injury caused by an unsafe act, in the average case, has had over 300 narrow escapes from serious injury as a result of committing the very same unsafe act. Likewise, persons are exposed to mechanical hazards hundreds of times before they suffer an injury.
The four basic motives or reasons for the occurrence of unsafe acts provide a guide to the selection of appropriate corrective measures. They are:
(a) Improper attitude
(b) Physical unsuitability
(c) Lack of knowledge or skill
(d) Improper environment
Four basic methods are available for preventing accidents:
(a) Engineering revision;
(b) Personal adjustment;
(c) Persuasion and appeal; and
The severity of an injury is largely not that serious but the occurrence of an accident that results in injury is largely preventable.
Most valuable methods in accident prevention are similar with the methods for the control of quality, cost and quantity of production.
Management has the best opportunity and ability to start the work of prevention; therefore, it should assume the responsibility.
The supervisor or foreman is the key man in accident prevention. His application of the art of supervision to control worker’s performance is the factor of greatest influence in successful accident prevention. It can be expressed as a simple four-step formula:
(a) Identify the problem
(b) Find and verify the reason for the existence of the problem
(c) Select the appropriate remedy
(d) Apply the remedy
The humanitarian incentive for preventing accidental injury is supplemented by two powerful economic factors:
(a) The safe establishment is efficient productively and the unsafe establishment is inefficient
(b) The direct cost for compensation and for medical treatment of occupational injuries is but one-fifth of the total cost which the employer must pay
