A) Ignore the electrolyte level

C) Add any available liquid to the battery

D) Drain the electrolyte from the battery

3 / 10

What type of floor should be used in the area where emergency batteries are stored?

A) Carpeted flooring

B) Insulated and acid-resistant flooring to prevent electrical hazards and protect against acid spills

C) Wooden flooring

D) Metallic flooring

4 / 10
