Question 1Calculation
An SDS lists a liquid's flash point as 60 °C. Your storage procedure separates liquids with flash points below 145 °F. What is the flash point in °F, and does the liquid need separate storage?
Show answer and source
Answer: D. 140.0 °F; yes
t/°C = (t/°F - 32)/1.8, so t/°F = 1.8 x 60 + 32 = 140.0 °F, which is below 145 °F.

Question 2Calculation
An SDS lists a liquid's flash point as 38 °C. Your storage procedure separates liquids with flash points below 95 °F. What is the flash point in °F, and does the liquid need separate storage?
Show answer and source
Answer: C. 100.4 °F; no
t/°C = (t/°F - 32)/1.8, so t/°F = 1.8 x 38 + 32 = 100.4 °F, which is not below 95 °F.

Question 3Calculation
A tote's label states 500 L. Your spill plan tracks containers in U.S. gallons. Using the NIST conversion factor, what volume should be entered?
Show answer and source
Answer: A. 132.1 gal
1 U.S. gallon = 3.785412 L, so 500 / 3.785412 = 132.1 gal. 4.546 L is the imperial gallon.
