According to the hierarchy of hazard controls, which measure is considered the most effective?
Answer: Elimination of the hazard
Elimination removes the hazard entirely from the workplace, making it the most effective control in the hierarchy because the hazard no longer exists.
Which of the following is an example of an engineering control for noise hazards?
Answer: Installing noise barriers around machinery
Engineering controls physically modify the work environment or equipment to reduce hazard exposure, such as installing sound barriers between workers and noise sources.
What is the primary purpose of a Job Hazard Analysis (JHA)?
Answer: To identify hazards associated with specific job tasks before work begins
A JHA systematically examines each step of a job task to identify associated hazards and implement appropriate controls before work begins, preventing injuries proactively.
Which hazard category includes chemical spills, toxic substances, and exposure to corrosive materials?
Answer: Chemical hazards
Chemical hazards encompass any substance that can cause harm through contact, inhalation, or ingestion, including spills, toxic materials, and corrosive agents.
When conducting a workplace hazard inspection, which approach is most effective?
Answer: Using a systematic, planned approach with a standardized checklist
A systematic, planned inspection using a checklist ensures consistent and comprehensive identification of hazards across all areas and hazard types, reducing the chance of oversights.
What does the Risk Priority Number (RPN) in a Failure Mode and Effects Analysis (FMEA) help determine?
Answer: The relative priority of risks based on severity, occurrence, and detectability ratings
The RPN is calculated by multiplying severity, occurrence, and detectability ratings, enabling safety professionals to prioritize which failure modes require the most urgent attention.
Which type of workplace hazard is associated with repetitive motion, awkward postures, and forceful exertions?
Answer: Ergonomic hazard
Ergonomic hazards involve physical factors related to how the body interacts with the work environment, including repetitive motion, awkward postures, and forceful exertions that can cause musculoskeletal injuries.
