Final answer:
To determine the number of fire wardens required on the floor of a Class E building, we calculate the total square footage of the floor and divide it by 7,500 (the typical square footage for one fire warden). In this case, the total square footage is 52,500 sq. ft., so seven fire wardens would be required.
Step-by-step explanation:
To determine the number of fire wardens required on the floor, we need to consider the total square footage of the floor and the number of tenants.
In this case, there are four tenants with 7,500 sq. ft. each, and one tenant with 22,500 sq. ft.
So, the total square footage of the floor is 4 * 7,500 + 22,500 = 30,000 + 22,500 = 52,500 sq. ft.
According to the National Fire Protection Association (NFPA), one fire warden is typically required for every 7,500 sq. ft. of floor space.
To calculate the number of fire wardens required, we divide the total square footage of the floor by 7,500.
52,500 / 7,500 = 7
Therefore, a Class E building with five tenants on each floor would require seven fire wardens on the floor.
