the minimum concentration of a refrigerant that can mixture of the refrigerant and air is known as the; a. acute toxicity exposure limit (atel). b. immediately dangerous to life or health conce c. lower flammability limit (lfl). d. upper explosive limit (uel).
Answer
# Brief Explanations:
The lower flammability limit (LFL) is the minimum concentration of a flammable substance (like a refrigerant) in a mixture with air below which the mixture will not burn. ATEL is related to toxicity, not flammability. Immediately dangerous to life or health is a different safety - related concept. UEL is the maximum concentration for flammability.
# Answer:
C. lower flammability limit (LFL)
