Generally speaking, there is no absolutely safe job in the world, only relative safety (that is, safety under certain conditions). In other words, there are more or less dangers in all human work (that is, risks that may endanger people's health and life and property safety), but the possibility of these dangers and the severity of their consequences are different.
Obviously, occupational health and safety is related to people's life safety and the vital interests of society, families and individuals. Once an accident happens, it will cause property loss and slight personal injury, as well as mass casualties and heavy losses of social property. Therefore, compared with quality management and environmental management, occupational health and safety management has more special and important significance.
Occupational health and safety management system is a systematic and standardized modern occupational health and safety management method. It especially emphasizes accident prevention, that is, all existing dangers and hidden dangers are found comprehensively and systematically in advance, and corresponding technical and management measures are taken to eliminate or control them in time, so that production and work have always been kept in a relatively safe state. At the same time, it also emphasizes just in case, that is, for possible accidents, it is necessary to make emergency preparations in advance and strengthen emergency drills to ensure that personal injuries and property losses caused by accidents will be reduced as much as possible in the future.
