Controls of health hazards in the workplace

Personal protective equipment (PPE) is the third category of health hazard control available to the IH or occupational health and safety professional. It is considered the last line of defense because the barrier separating the employee from the health hazard must be worn correctly and consistently. If the employee does not wear the PPE or it fails, they will be at greater risk for illness or injury. It is an unfortunate fact that for many occupational safety and health programs, PPE is the symbol of the safety program rather than a last resort. 

The main reason why administrative controls and PPE are not considered the preferred methods for protecting worker health is that the health hazards still exist in the workplace and can present a risk. In many instances, both administrative controls and PPE can be circumvented. Employees, for example, may use the wrong respirator for a particular hazard. This mistake will result in the employee inhaling toxic vapors or dusts, thus increasing their risk of occupational disease.
