the minimum concentration of a refrigerant that can propagate a flame through a mixture of the refrigerant and air is known as the; a. acute toxicity exposure limit (atel). b. immediately dangerous to life or health concentration (idlh). c. lower flammability limit (lfl). d. upper explosive limit (uel).
Answer
# Brief Explanations:
The lower flammability limit (LFL) is defined as the minimum concentration of a flammable substance in a mixture with air that can support combustion and propagate a flame. ATEL is related to toxicity, IDLH is about immediate danger to life - health, and UEL is the maximum concentration for explosion.
# Answer:
C. lower flammability limit (LFL)
