NSC Hazard Recognition 2 — Questions and Answers
Question 1: Which of the following is an example of an ergonomic hazard in the workplace?
- Spilled chemicals on the floor
- Repetitive motion tasks performed daily (Correct answer)
- Loud machinery noise above 85 dB
- Exposed electrical wiring
Correct answer: Repetitive motion tasks performed daily
Ergonomic hazards include repetitive motions, awkward postures, and forceful exertions that can lead to musculoskeletal disorders.
Question 2: A worker notices a colleague using an angle grinder without a face shield. What type of hazard does this represent?
- Chemical hazard
- Biological hazard
- Physical hazard from flying debris (Correct answer)
- Ergonomic hazard
Correct answer: Physical hazard from flying debris
Angle grinders produce sparks and flying debris that pose a physical hazard to unprotected eyes and face.
Question 3: Which condition would MOST likely be identified as a slip hazard during a workplace inspection?
- A frayed electrical cord near a workstation
- A wet floor near the building entrance without signage (Correct answer)
- An improperly labeled chemical container
- An overloaded electrical outlet
Correct answer: A wet floor near the building entrance without signage
Wet floors without warning signs create slip hazards because workers cannot anticipate the loss of traction.
Question 4: In a confined space entry scenario, which hazard should workers check for FIRST before entering?
- Noise levels
- Atmospheric hazards such as oxygen deficiency or toxic gases (Correct answer)
- Lighting adequacy
- Temperature extremes
Correct answer: Atmospheric hazards such as oxygen deficiency or toxic gases
Atmospheric hazards are the leading cause of confined space fatalities and must be tested before entry.
Question 5: Which of the following best describes a 'near miss' in safety terminology?
- An injury requiring medical treatment beyond first aid
- An incident that could have resulted in injury but did not (Correct answer)
- A hazard identified during a formal audit
- A recordable OSHA illness or injury
Correct answer: An incident that could have resulted in injury but did not
A near miss is an unplanned event that did not result in injury or damage but had the potential to do so.
Question 6: Which action is part of the 'recognize' step in the NSC hazard recognition process?
- Implementing engineering controls
- Identifying potential sources of harm in the work environment (Correct answer)
- Evaluating the severity of an existing injury
- Reporting an incident to OSHA
Correct answer: Identifying potential sources of harm in the work environment
Recognizing hazards means identifying sources of potential harm before an injury or illness occurs.
Question 7: A storage rack is overloaded beyond its rated capacity. This is BEST classified as which type of hazard?
- Biological hazard
- Chemical hazard
- Structural/physical hazard (Correct answer)
- Radiation hazard
Correct answer: Structural/physical hazard
An overloaded storage rack poses a structural failure risk, making it a physical hazard that can cause injury from collapse.
