Question

directions: answer the following questions. 1. which of the following is a true statement? a. anticipation can be accomplished by knowing the history of the work involved b. recognition includes identifying personal protective equipment c. evaluation includes safe working practices d. control includes environmental monitoring 2. which of the following is the first preference in the hierarchy control? a. administrative b. personal protective equipment c. elimination of hazard d. engineering 3. which of the following is a suggested tip for chemical hazards? a. guarding exposed parts b. drinking plenty of fluids c. being aware of footing d. knowing compatible and incompatible substances 4. which of the following is a biological hazard? a. dust b. fibers c. mold d. noise 5. which of the following is not a top potential hazard on the job site? a. repetitive motion injuries b. scaffolding collapse c. rigging d. electrical shock

Explanation:

1. Knowing the history of work can help in anticipation of potential issues. Recognition is about identifying hazards in general, not specifically PPE. Evaluation is about assessing risks and control measures, not just safe - working practices. Control is about implementing measures to reduce or eliminate hazards, not environmental monitoring.
2. In the hierarchy of control, elimination of the hazard is the most effective and preferred method as it removes the hazard at the source.
3. For chemical hazards, knowing which substances are compatible and incompatible is crucial to prevent chemical reactions, spills, and other incidents. Guarding exposed parts is for mechanical hazards, drinking fluids is for heat - related or general health, and footing awareness is for physical slips/trips.
4. Mold is a biological hazard as it is a living organism that can cause health problems such as allergies and respiratory issues. Dust and fibers can be physical or chemical hazards depending on the material, and noise is a physical hazard.
5. Repetitive motion injuries are a long - term ergonomic hazard, while scaffolding collapse, rigging, and electrical shock are immediate and high - risk potential hazards on a job site.

Answer:

1. A. Anticipation can be accomplished by knowing the history of the work involved
2. C. Elimination of hazard
3. D. Knowing compatible and incompatible substances
4. C. Mold
5. A. Repetitive motion injuries
