Document Summary

Safety hazards are due to material handling, machines, energy, work practices, and confined spaces. Material handling hazards: these can lead to muscle strains due to lifting and carrying materials. The use of devices such as forklifts, cranes, etc. exposes the worker to accidental contact with the moving equipment. Machine hazards: rotating shafts, moving belts, presses, etc. can cause very serious injuries. Energy hazards: all energy sources such as electricity, steam, hydraulic pressure, etc. can lead to serious injury. Work practice hazards: failure to follow safe operating procedures may lead to serious injuries. Confined space hazards: in such 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. Vary based on type of activity, can cause discomfort, illness, and lack of efficiency among workers. Occupational health hazards can be classified as physical, chemical, biological and ergonomic.
