Document Summary
Physical agents: pressure & temperature, noise & vibration, radiation. Examples for each: compressed gases, flammable and combustible materials, oxidizing materials, poisonous & infectious materials, corrosive materials, dangerously reactive materials: Food poisoning, rabies, tuberculosis and hepatitis are some of the infections caused by biological agents. These include: bacteria, fungi, viruses and other micro-organisms and their associated toxins. Ergonomics can be defined as the science or study of work. It is a way of designing a work environment to fit people. The mere presence of a causative agent does not necessarily constitute a hazard. Exposure = mg/m3 and ug/m3 , ppm, ppb, % Classification for the effects of over exposure to toxicants based on: duration of the effect, organs affected and physiol. Duration of effect = 1) acute: soon to exposure (fast), brief exposure, high contaminant: chronic: late in exposure (slow), low and repeated exposure.
