Scenario 6-1: Custodial staff (also known as janitors or cleaners) are the unsung heroes of the workplace. Going about their work while many of us are in bed, they deal with a whole host of situations that bring them into contact with a wide range of chemical and biological agents. They are exposed to residues left in the air and on surfaces from manufacturing processes, from service operations, and from human excretions (sweat, body oils, from sneezing, and so on). While employees of the firms that they service receive training about specific chemical and biological hazards, the custodial staff are often unaware of some of the hazards that they may encounter. -What two food-related biohazards could cause custodial staff to fall victim to food poisoning if they do not have a way to properly store the food they brought from home for their meal break at 3a.m.?

Toxicity is the main determinant of assessing the potential degree of seriousness of a chemical hazard.
