Who is responsible for posting or changing the fire symbol?

The individual responsible for posting or changing the fire symbol is the person-in-charge of the operation. This role is critical because they have direct oversight of the specific area where operations involving munitions take place. They are tasked with ensuring that all safety protocols are adhered to and that the appropriate warnings, such as fire symbols, are correctly displayed to inform personnel of potential hazards. This ensures not only compliance with safety regulations but also the overall safety of the work environment.

While other roles, like the safety officer, the warehouse manager, or the fire chief, may be involved in broader safety practices or emergency response planning, the operational authority and responsibility for signage like fire symbols directly falls under the purview of the person managing the operation in that specific context.
