GCAP Safety Test Exam Questions &
Answers (Grade A+)
NH3 -
correct answer ✅Base: Ammonia has a pH of 11.6, making it highly
alkaline.
1 Kitchen Match -
correct answer ✅The heat released by burning a kitchen match
from end to end is equivalent to 1 BTU.
NH3 Evaporation -
correct answer ✅Evaporating 1 lb of ammonia absorbs 561 BTU of
heat, making it effective for cooling.
NH3 Efficiency vs. Freon -
correct answer ✅Ammonia is 7x more efficient than Freon,
reducing energy costs.
Ammonia Detection -
correct answer ✅Humans can smell ammonia at 2-5 ppm.
PPM Conversion -
correct answer ✅1% = 10,000 ppm.
, GCAP Safety Test Exam Questions &
Answers (Grade A+)
0.5% NH3 (5000 ppm) -
correct answer ✅This concentration can be lethal without PPE.
PEL for NH3 -
correct answer ✅OSHA's Permissible Exposure Limit (PEL) for
ammonia is 50 ppm.
IDLH Defined -
correct answer ✅Ammonia is classified as Immediately Dangerous
to Life and Health (IDLH) at concentrations above 300 ppm.
Respirators Not Effective at 300+ ppm -
correct answer ✅Full-face air-purifying respirators cannot protect
above this concentration.
100 lb NH3 Release Reporting -
correct answer ✅Notify: National Response Center (NRC), Local
Emergency Planning Committee (LEPC), State Emergency Response
Commission (SERC), EPA Regional Director.
