Other general industry hazards: practice questions
Our OSHA 10 General Industry bank has 19 questions on this topic. Here are 5 of them with answers; the full mock exam draws from every topic, like the real one.
Question 1
When is a fire watch required for welding or cutting?
- Only when welding outdoors in windy weather
- Only on weekends, when fewer workers are in the building to spot a fire
- Never, if the welder has an extinguisher
- When appreciable combustibles are closer than 35 feet, or other conditions where more than a minor fire might develop
Show the answer
D. When appreciable combustibles are closer than 35 feet, or other conditions where more than a minor fire might develop — Fire watchers are required where other than a minor fire might develop, including when appreciable combustible material is closer than 35 feet to the work.
Question 2
Which color designates caution and marks hazards such as tripping, falling and being caught in between?
- Red
- Orange
- Green, the color of safety and first aid equipment
- Yellow
Show the answer
D. Yellow — Yellow is the basic color for designating caution and marking physical hazards such as striking against, stumbling, falling, tripping and "caught in between."
Question 3
Under OSHA's Recommended Practices, which approach controls hazards most effectively?
- Relying mainly on PPE because it is quickest
- Warning signs only, because signs are cheaper and quicker to put up than any other control
- Following the hierarchy of controls, starting with elimination and engineering controls
- Waiting for an injury before acting
Show the answer
C. Following the hierarchy of controls, starting with elimination and engineering controls — OSHA's recommended practices tell employers to identify and evaluate control options using a "hierarchy of controls," which favors eliminating hazards and engineering controls over PPE.
Question 4
What do danger signs indicate under 1910.145?
- A possible hazard against which care should be taken
- Immediate danger requiring special precautions
- General safety instructions
- Directions to the nearest exit
Show the answer
B. Immediate danger requiring special precautions — Employees must be instructed that danger signs indicate immediate danger and that special precautions are necessary; caution signs indicate a possible hazard.
Question 5
What is OSHA's 8-hour permissible exposure limit for carbon monoxide in Table Z-1?
- 5 ppm
- 50 ppm
- 500 ppm
- 200 ppm, as a ceiling that can never be exceeded
Show the answer
B. 50 ppm — Table Z-1 lists carbon monoxide at 50 ppm (55 mg/m3) as an 8-hour time-weighted average.
