Exam 6: Biological and Chemical Agents

Differentiate between chemical and biological agents. Identify a biological or chemical agent present in your workplace or in a workplace with which you are familiar (either by knowing someone who works there or by being a customer/patient). Explain the route of entry, type(s) of toxicity involved, and the health effects that this specific agent can have on the human body. Describe the controls that should be put in place to control this hazard.

Question 1

Correct Answer:

Verified

Chemical agents are hazards created by any one or any combination of a very large number of chemicals and/or their physical reactions. Biological agents or biohazards are natural organisms or products of organisms that present a risk to humans.
The chemical and biological hazards that students may have observed/know about should reflect terminology from one of the following sources: Types of Contaminants (OH&S Notebook 6.1); Classification of Toxic Substances (OH&S Notebook 6.4); Organic Solvents (Table 6.2); or Biological Agents (Table 6.1).
Students should clearly identify route(s) of entry (inhalation (respiration), ingestion, penetration, or skin absorption) and provide a clear description of the toxicity (acute versus chronic, local versus systemic), in addition to the actual health effects (injury or illness).
Descriptions of controls should mention more than one approach (see Fig. 6.3, Engineering, Work Practices, and Medical Control Measures) for an overview of engineering, work practices, PPE, personal hygiene practices, good housekeeping, medical surveillance, and record-keeping controls.

Question 4

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 characteristic of chlorinated solvents could ultimately result in liver problems from cleaners?
