The spray bottle must be labeled with all the information from the manufacturer's original label.

Correct answer: The spray bottle does not require a label as long as it remains under the control of the employee who made the transfer and is used within that work shift.

OSHA's HCS has an exception for portable containers. According to 29 CFR 1910.1200(f)(8), employers are not required to label portable containers into which hazardous chemicals are transferred from labeled containers, and which are intended only for the immediate use of the employee who performs the transfer. If the chemical is not used up within the shift or is left unattended, it must be properly labeled.

When more than 10 workers are on a roof simultaneously
Whenever any employee works at height
Whenever scaffolding is used at any height

Correct answer: Only when conventional fall protection is infeasible or creates a greater hazard

A written fall protection plan is required under OSHA only when conventional fall protection systems (guardrails, nets, PFAS) are infeasible or would create a greater hazard, and the plan must be prepared by a qualified person.

Question 17: Which of the following workers is NOT covered by OSHA?

15

Correct answer: 2

OSHA regulations mandate that excavated material (spoil piles) and equipment must be kept at least 2 feet (0.6 meters) away from the edge of an excavation. This critical safety measure prevents materials or equipment from falling into the trench, which could injure workers below, and helps maintain the stability of the trench walls, reducing the risk of collapse.
