Which of the following is NOT a contributing factor to large losses in industrial occupancies?

Proper labeling of containers is indeed not a contributing factor to large losses in industrial occupancies. In fact, proper labeling is essential for ensuring safe handling and storage of hazardous materials. It helps identify the contents of containers clearly, reducing the risk of accidental fires, spills, or chemical reactions that can lead to significant losses.

On the other hand, inadequate fire protection systems, temporary storage in aisles, and improper maintenance can all lead to increased risks and potential for large-scale losses in industrial settings. An inadequate fire protection system may fail to control or extinguish a fire effectively, while temporary storage in aisles can obstruct access to emergency exits and firefighting equipment. Improper maintenance can lead to malfunctions in fire safety equipment or failure to detect hazards, which could exacerbate a crisis situation. Therefore, while proper labeling serves as a preventative measure, the other factors mentioned are associated with a higher risk of loss.
