What is the maximum amount of volatile inflammable fluid allowed in an approved safety can for habitation?

The correct answer indicates that the maximum amount of volatile inflammable fluid allowed in an approved safety can for habitation is 1 quart. This regulation is in place to ensure safety in residential areas, as volatile substances can pose significant risks, including fire hazards and health risks due to fumes.

By limiting the amount to 1 quart, safety regulations aim to minimize the potential for accidents and to ensure that the risks associated with the storage of such dangerous materials are kept to an absolute minimum in areas where people live and congregate.

Higher quantities, such as 2 quarts, 3 quarts, or 5 quarts, would increase the potential danger, as larger amounts of volatile substance would result in a greater risk of ignition, explosion, and toxic exposure should a leak or spill occur. Thus, the limitation to 1 quart is a precaution to promote safety in domestic environments.
