ABSTRACT
This chapter addresses protocols detailing how to conduct hazard assessments for the selection of personal protective equipment (PPE), respiratory protection, protective clothing, and other protective equipment. It reviews the process and the essence of the OSHA requirements. Biological hazards include infection from agents and disease common to humans, those common to animals, and those common to the work environment. Biological hazards common to humans include pathogenic microbes such as those causing AIDS, hepatitis, TB, Legionnaires disease and others. The most common route of entry for hazardous materials in the industrial environment is by the respiratory route. There are many processes which can generate airborne particulates, vapors, and gases of concern. Oxygen-deficient atmospheres can be created naturally through oxygen displacement by decomposition, the depletion of oxygen through oxidation, the addition of other gases, or through other means.
