Question 1

When selecting gloves for protection against chemical hazards, what is the most important factor to consider?

Accepted Answer

The chemical compatibility of the glove material with the specific substance

Chemical compatibility must be verified because no single glove material protects against all chemicals, and an incompatible glove can degrade rapidly and allow exposure.

Question 2

ANSI/ISEA Z41 (now ASTM F2413) governs which category of personal protective equipment?

Accepted Answer

Safety footwear including toe protection

Answer

ASTM F2413 (formerly ANSI Z41) is the standard for performance requirements for protective footwear, including impact and compression resistance ratings.

Question 3

A full-body harness used in a personal fall arrest system must be inspected by a competent person:

OSHA requires fall arrest equipment to be inspected before each use and immediately removed from service after any fall event, as internal damage may not be visible.
