SAFETY

1. Safety is concerned with those activities that seek either to minimise or to eliminate hazardous conditions that can cause bodily injury. Safety precautions fall under two principal headings, occupational safety and public safety. Occupational safety is concerned with risks encountered in areas where people work: offices, manufacturing plants, farms, construction sites, and commercial and retail facilities. Public safety involves hazards met in the home, in travel and recreation, and other situations not falling within the scope of occupational safety.

2. Safety was not considered to be a matter of public concern in ancient times, when accidents were regarded as inevitable or as the will of the gods. Today the concern for safety is world-wide and is the province of numerous governmental and private agencies at the local, national, and international levels.

3. Several international organisations provide means by which national safety organisations can exchange information and pass on new ideas. Among them are the International Social Security Association (ISSA) and the International Labour Organisation (ILO). A number of organisations including the ILO, ISSA, the World Health Organisation, and the European Economic Community, maintain a joint information bureau in Geneva. The International Organisation for Standardisation, which is also based in Geneva, helps establish safety codes and standards for numerous areas of activity among many nations that sponsor it.

4. Among the chief activities of individuals and organisations concerned with safety are the collection of statistics on accidents and injuries and the publication of analyses of those statistics; the study of hazardous situations and environments and the development of safer designs, procedures, and materials; the development of educational programs for employers, and materials; the development of educational programs for employers, workers, drivers, and other groups at risk; and the design of machines, workplaces, and safety equipment that minimise the risk of injury.
