Document Summary
In a workplace, the worker may be exposed to: Based on the nature of the work, safety hazards are due to material handling, machines, energy, work practices, and confined spaces. Energy hazards: all energy sources can lead to muscle strains due to lifting and carrying materials. Work practice hazards: failure to follow safe operating procedures may lead to serious injuries. spaces (for example, silos, storage tanks, pipelines etc. ) hazards arise due to difficulty of entry and exit, build-up of hazardous materials and oxygen deficiency. The extent of occupational health hazards varies with the type of activity. However, such hazards may have the potential to cause severe discomfort, illness, and lack of efficiency among workers. Based on the nature of the causative agent (or factor), occupational health hazards can be classified as physical, chemical, biological and ergonomic. It is very important to note that the mere presence of a causative agent does not necessarily constitute a hazard.
