Associate Safety Professional Exam

Question 1

A workplace noise survey records the following daily exposures: 90 dBA for 4 hours, 95 dBA for 2 hours, and 100 dBA for 1 hour. Using OSHA's permissible exposure limits (PEL) and the dose equation D = (C1/T1 + C2/T2 + C3/T3), what is the noise dose?

D = 1.25 (exceeds PEL) D = 0.75 (within PEL) D = 1.00 (exactly at PEL) D = 0.50 (well within PEL)

Correct Answer:

D = 1.25 (exceeds PEL)

Question 2

A chemical has a TWA-TLV of 50 ppm. Air sampling over an 8-hour shift yields the following results: 60 ppm for 3 hours, 40 ppm for 3 hours, and 55 ppm for 2 hours. What is the 8-hour TWA concentration?

51.25 ppm — exceeds the TLV 50.00 ppm — exactly at the TLV 48.75 ppm — below the TLV 55.00 ppm — equals the highest sample

Correct Answer:

51.25 ppm — exceeds the TLV

Question 3

In toxicology, the LD50 value of a substance is used to:

Compare the relative acute toxicity of substances on a standardized basis Determine the concentration at which 50% of exposed workers will develop cancer Set OSHA permissible exposure limits for air contaminants Calculate the lethal dose for a specific individual based on body weight

Correct Answer:

Compare the relative acute toxicity of substances on a standardized basis

Question 4

A safety professional needs to calculate the dilution ventilation required to control a solvent with an evaporation rate of 1 pint/hour. The solvent has a specific gravity of 0.88 and a molecular weight of 92. The TLV is 100 ppm. Using the standard dilution ventilation formula, approximately how many cubic feet per minute (CFM) of fresh air are needed (using K=10)?

Approximately 11,300 CFM Approximately 1,130 CFM Approximately 5,650 CFM Approximately 22,600 CFM

Correct Answer:

Approximately 11,300 CFM

Question 5

A fault tree analysis assigns the following probabilities: Event A = 0.10, Event B = 0.05. If these two events are connected by an AND gate, what is the probability of the top event occurring?

0.005 0.15 0.005 or 0.15 depending on dependency 0.50

Correct Answer:

0.005
