Sample questions

What is the main purpose of a standard fuse or circuit breaker?

  1. To keep the voltage steady when loads change
  2. To provide a path to ground for fault current
  3. To protect conductors and equipment from overcurrent
  4. To protect workers from shock at any current level
Show the answer

C. To protect conductors and equipment from overcurrent

Overcurrent devices open the circuit when current exceeds the rating of the conductors or equipment, preventing overheating and fire. They trip at many amperes, far above the fraction of an ampere that can kill a person, so they are not shock protection.

Which statement about an exit route door is correct?

  1. It must open from the inside without keys, tools or special knowledge
  2. It must be a sliding or roll-up door wide enough for a forklift to pass
  3. It may be locked from the inside if a key hangs beside the door
  4. It may be chained shut after hours if an alarm is installed
Show the answer

A. It must open from the inside without keys, tools or special knowledge

Employees must be able to open an exit door from the inside at all times without keys, tools or special knowledge; a panic bar that locks only from the outside is acceptable. A key hanging nearby still requires a key and can be lost in smoke or darkness.

Reference: 29 CFR 1910.36(d)

A worker splashes a solvent on her arm and wants to know what to do right away. Which safety data sheet section covers this?

  1. Section 6, Accidental release measures
  2. Section 4, First-aid measures
  3. Section 8, Exposure controls and PPE
  4. Section 2, Hazard identification
Show the answer

B. Section 4, First-aid measures

Section 4 describes first-aid measures by route of exposure, along with the most important symptoms. Section 6 is the tempting wrong answer, but it deals with cleaning up spills and leaks, not treating a person.
