CCI Safety Regulations & Compliance 3 — Questions and Answers
Question 1: Which document must an employer provide to workers before they begin work in a confined space classified as permit-required?
- A toolbox talk sign-in sheet
- A written entry permit (Correct answer)
- A site safety plan
- A confined space risk matrix

OSHA 1926.1203 requires a written permit documenting hazards, controls, and authorized entrants before entry into a permit-required confined space.
Question 2: Under OSHA 1926.403, electrical equipment used on construction sites must be listed or labeled by:
- The project electrical engineer
- A nationally recognized testing laboratory (NRTL) (Correct answer)
- The local AHJ only
- The equipment manufacturer's QA department
Correct answer: A nationally recognized testing laboratory (NRTL)
OSHA requires electrical equipment to be listed by a Nationally Recognized Testing Laboratory such as UL or ETL.
Question 3: Ground fault circuit interrupters (GFCIs) are required on construction sites for all 120-volt, single-phase, 15- and 20-ampere receptacles. Which OSHA subpart contains this requirement?
- Subpart K – Electrical (Correct answer)
- Subpart M – Fall Protection
- Subpart O – Motor Vehicles
- Subpart Q – Concrete
Correct answer: Subpart K – Electrical
OSHA Subpart K (1926.404) contains GFCI requirements for temporary power on construction sites.
Question 4: A construction inspector observes a scaffold plank with a visible crack running along its length. The correct action is to:
- Allow use if crack is less than ¼ inch wide
- Tag it out of service and remove it immediately (Correct answer)
- Reinforce it with duct tape and monitor
- Allow use only for light-duty work below 10 feet
Correct answer: Tag it out of service and remove it immediately
Cracked or damaged scaffold planks must be immediately removed from service to prevent catastrophic failure under load.
Question 5: OSHA's Silica standard for construction (29 CFR 1926.1153) requires medical surveillance for workers exposed above the action level for how many years?
- 1 year
- 3 years
- 5 years

Correct answer: 30 years or more
The silica standard requires medical surveillance when workers are exposed at or above the action level for 30 or more days per year.
Question 6: Under the OSHA Lockout/Tagout standard (29 CFR 1910.147), which step must occur FIRST in an energy control procedure?
- Apply lockout devices to all energy-isolating points
- Notify affected employees of the shutdown
- Verify zero energy state with a test
- Shut down the equipment using normal stopping procedures (Correct answer)
Correct answer: Shut down the equipment using normal stopping procedures
The equipment must first be shut down using its normal stopping procedure before energy isolation devices are applied.
Question 7: The OSHA multi-employer worksite policy states that a controlling employer is one who:
- Has the most workers on site
- Owns the land where construction occurs
- Has general supervisory authority over the worksite (Correct answer)

Correct answer: Has general supervisory authority over the worksite
OSHA's multi-employer citation policy defines the controlling employer as one with general supervisory authority over the worksite.
