Document Summary

Hrm 3400 winter 2012 anna blake. Lecture 2 chemical/biological agents jan 16. D poisonous and infectious material: d1 materials causing immediate and serious toxic effects, d2 materials causing other toxic effects, d3 biohazardous infectious material. No toxicity data on about 80% of the chemicals. 80% of occupational illnesses are a result of chemical exposures: cancer, lung diseases, blood abnormalities, nervous system disorders, birth defects, skin problems and sterility. Ontario occupational health and safety act: sections 33, 35, 37-39. State is determined by temperature and pressure. Chemicals have different melting, freezing and boiling points. Liquid and gas/vapour states result in the majority of chemical related health problems. Airborne respirable contaminants, such as liquid droplets, solid particulate, or vapours dispersed in air that are of a fine enough particle size (0. 01 to 100 micrometres) to remain suspended for a period of time. Setting rate: the time in seconds that it takes for an airborne particle to fall one foot.
