GCAP INDUSTRIAL AMMONIA
REFRIGERATION TEST PAPER
EXAMINATION TEST PRACTICE SOLUTION
2026 100% CORRECT.
⫸ 1 Kitchen Match. Answer: The heat released by burning a kitchen
match from end to end is equivalent to 1 BTU.
⫸ NH3 Evaporation. Answer: Evaporating 1 lb of ammonia absorbs
561 BTU of heat, making it effective for cooling.
⫸ NH3 Efficiency vs. Freon. Answer: Ammonia is 7x more efficient
than Freon, reducing energy costs.
⫸ Ammonia Detection. Answer: Humans can smell ammonia at 2-5
ppm.
⫸ PPM Conversion. Answer: 1% = 10,000 ppm.
⫸ 0.5% NH3 (5000 ppm). Answer: This concentration can be lethal
without PPE.
⫸ PEL for NH3. Answer: OSHA's Permissible Exposure Limit (PEL)
for ammonia is 50 ppm.
