List and provide a brief description of the classes of chemical agents that are the predominant cause of dermatitis in the workplace.
Your Answer:
1) Detergents and solvents: remove the natural oils for the skin or react with oils of the skin to increase susceptibility to reaction form chemicals that ordinarily do not affect the skin
Desiccators, hygroscopic agents and anhydrides take the water out of the skin and generate heat.
3) Protein precipitants tend to coagulate the outer layers of ht skin.
4) Oxidizers unite with hydrogen and liberate nascent oxygen on the skin
5) Solvents the extract essential skin constituents
6) Allergic or anaphylactic proteins that stimulate the production of antibodies that cause skin reaction in sensitive people.

Question 20
Not yet graded / 0 pts
List and describe the three types of control methods for workplace hazards in order of preference.
Your Answer:
1) Engineering controls are used to engineer out the hazard, either by initial design specification;
or by applying method of substitution, isolation, enclosure or ventilation. In
2) Administrative controls reduce employee exposure by scheduling reduced work time in contaminant area, or during cooler time of the day for heat stress exposure. This also includes training .
3) Personal protective equipment that employees wear to protect them form their environment.

Give a brief description of biological hazards in the workplace.
Your Answer:
Biological hazards are any living organism or it properties that can cause an adverse response in humans. They can be part of the total environment or associated with a particular occupation.
