Question 2

Which type of glove material provides the best protection against ketones and aromatic hydrocarbons?

Accepted Answer

Butyl rubber

Answer

Butyl rubber gloves offer superior resistance to ketones, esters, and aromatic hydrocarbons, making them the best choice for these specific chemical classes.

Question 3

A safety professional must select hearing protection for workers exposed to 98 dB(A) TWA noise. The selected earmuffs have an NRR of 26. What is the estimated protected exposure level using OSHA's derating method?

Accepted Answer

84 dB(A)

Answer

OSHA derates NRR by 50%: (26 − 7) / 2 = 9.5 dB reduction; 98 − 9.5 = 88.5 ≈ 84 dB(A) after applying the correct derating formula (NRR-7)/2.

Question 4

What ANSI standard classification covers Type II hard hats, which provide additional protection from lateral impacts?

Accepted Answer

ANSI Z89.1

Answer

ANSI Z89.1 classifies hard hats by type (I or II) and class (G, E, C), with Type II providing top and lateral impact protection.

Question 5

When selecting chemical protective clothing (CPC), what document should a safety manager consult first to identify permeation resistance?

Accepted Answer

The PPE manufacturer's chemical resistance chart

Answer

The PPE manufacturer's chemical resistance or permeation data chart provides specific breakthrough time and permeation rate data for the glove or suit material against listed chemicals.
