Question 1

Heat stroke is distinguished from heat exhaustion primarily by:

Accepted Answer

Loss of thermoregulation and elevated core body temperature above 104°F (40°C)

Answer

Heat stroke is a medical emergency characterized by thermoregulatory failure, core temp >104°F, and often altered mental status.

Question 2

When using a direct-reading instrument to assess solvent vapor concentrations, the instrument response factor must be applied because:

Accepted Answer

Instruments are calibrated to a reference gas and respond differently to other compounds

Answer

Photoionization detectors (PIDs) and similar instruments are calibrated to isobutylene; response factors adjust readings to actual contaminant concentrations.

Question 3

Under OSHA's confined space standard (29 CFR 1910.146), an 'attendant' is responsible for:

Accepted Answer

Monitoring conditions inside and outside the permit space and summoning rescue if needed

Answer

The attendant stays outside the permit space, monitors entrants and conditions, maintains communication, and initiates rescue procedures.

Question 4

The biological exposure index (BEI) established by ACGIH is best described as:

Accepted Answer

A reference value for evaluating biological specimens to assess worker chemical absorption

Answer

BEIs are ACGIH guidance values for biological monitoring (urine, blood, exhaled air) that correlate with TLV exposures.

Question 5

A drum labeled with a Class 6.1 DOT hazard class contains:

Accepted Answer

Toxic material

Answer

DOT hazard Class 6.1 designates toxic materials (poisons) that are hazardous to human health during transport.
