For a temporary installation, what is the minimum number of extinguishers required for class 2A and class 10-BC, in addition to NFPA 10 requirements?

• A. Two Class 2A and Two Class 10-BC
• B. Four Class B extinguishers
• C. Two Class 10-BC extinguishers
• D. One Class A extinguisher

Answer: (A)

In temporary installations, you need extinguishers that cover the most likely fire hazards and also provide redundancy beyond the basic placement rules. Two extinguishers with a 2A rating address ordinary combustibles, while two extinguishers with a 10-B:C rating cover flammable liquids and energized electrical fires. Having both types on hand ensures you can tackle the common fire scenarios that might arise in a temporary setup and still have backups available if one unit is in use or moved. The other options don’t provide this combination of hazard coverage and redundancy, so they don’t meet the needs of a temporary installation as described.
