During minor renovations, the number of containers in a building shall not exceed what?

The correct answer focuses on the number of workers in the building. This concept is rooted in safety practices during renovations, where it's important to ensure that the quantity of hazardous materials, such as propane containers, is proportional to the amount of personnel present. It can help in mitigating risks associated with fire hazards, exposure levels, and emergency response situations.

When there is a limited number of workers in the area, it is safer to have fewer containers, thus reducing the potential risk of accidents or incidents related to propane usage. This practice aligns with broader safety regulations which often base their standards on occupancy or personnel levels to manage risk effectively.

The emphasis on this principle aligns with other safety guidelines and protocols likely found in local regulations or fire codes, but the specific requirement pertains to the workforce present. This ensures that safety measures are adequately proportional to the working conditions at hand.

The other choices pertain to broader regulations or standards that, while important, do not directly address the specific safety practice of limiting the number of containers based on worker count during minor renovations.
