Occupational exposures

Occupational exposures include physical conditions(for example, structural insecurity ordeficient lighting), physical stress (for example,lifting heavy weights or repetitive strain injuries),physical agents (for example, noise, vibration, orradiation), chemicals (for example, dusts orsolvents), biological agents (for example, bacteriaor viruses), and psychosocial stressors (for example,low control over job tasks or poor communication with workmates, see Job strain model). Although many occupational exposures mayoccur as environmental exposures for the generalpopulation,workers are usually exposed to higherlevels and are frequently the focus of research onhealth effects of these exposures and agents.
