ISAC Laboratory Safety and Procedures 1 — Questions and Answers
Question 1: What is the purpose of a Job Safety Analysis (JSA)?
- To identify potential hazards in each step of a job and determine preventive measures (Correct answer)
- To calculate employee productivity rates
- To determine pay scales for hazardous work
- To schedule maintenance activities
Correct answer: To identify potential hazards in each step of a job and determine preventive measures
A JSA systematically examines each step of a job to identify hazards and establish preventive controls before work begins.
Question 2: Which organization sets and enforces workplace safety standards in the United States?
- OSHA (Occupational Safety and Health Administration) (Correct answer)
- EPA (Environmental Protection Agency)
- FDA (Food and Drug Administration)
- FTC (Federal Trade Commission)
Correct answer: OSHA (Occupational Safety and Health Administration)
OSHA is the federal agency responsible for setting and enforcing workplace safety and health standards.
Question 3: What is the hierarchy of controls for workplace hazards?
- Elimination, substitution, engineering controls, administrative controls, PPE (Correct answer)
- PPE, administrative controls, engineering controls, substitution, elimination
- Administrative controls, PPE, elimination, substitution, engineering controls
- Engineering controls, elimination, PPE, substitution, administrative controls
Correct answer: Elimination, substitution, engineering controls, administrative controls, PPE
The hierarchy of controls prioritizes the most effective methods first: eliminating the hazard is preferred over relying on personal protective equipment.
Question 4: What must employers provide to employees regarding hazardous chemicals in the workplace?
- Safety Data Sheets (SDS) and hazard communication training (Correct answer)
- Only verbal warnings about chemical dangers
- Chemical information only upon written request
- Nothing if chemicals are in small quantities
Correct answer: Safety Data Sheets (SDS) and hazard communication training
The Hazard Communication Standard requires employers to provide SDS and training about chemical hazards in the workplace.
Question 5: When should personal protective equipment (PPE) be used?
- When hazards cannot be adequately controlled through other means (Correct answer)
- Only during inspections
- Only when working with chemicals
- As a substitute for all other safety measures
Correct answer: When hazards cannot be adequately controlled through other means
PPE is the last line of defense and should be used when engineering and administrative controls cannot fully eliminate hazards.
Question 6: What is the purpose of a safety audit?
- To systematically evaluate workplace conditions and safety program effectiveness (Correct answer)
- To find reasons to terminate employees
- To reduce insurance premiums only
- To satisfy union requirements exclusively
Correct answer: To systematically evaluate workplace conditions and safety program effectiveness
Safety audits provide systematic evaluation of safety programs, identify deficiencies, and drive continuous improvement.
