Under what condition can highly flammable liquids be used for cleaning near explosives?

Highly flammable liquids must only be used for cleaning near explosives when authorized by a Technical Order. Technical Orders are official documents that outline the proper procedures and safety measures for handling specific materials and equipment in military operations. These orders take into account the risks associated with using flammable substances near explosives and provide guidance based on established safety protocols.

The use of Technical Orders ensures that personnel follow standardized procedures that have been vetted for safety, minimizing the risk of accidents or hazards. This is critical when dealing with potentially dangerous materials in environments where explosives are present. Utilizing flammable liquids without the explicit approval provided by a Technical Order poses significant safety risks, regardless of other conditions like weather, personal protective equipment, or ventilation. Therefore, adherence to these orders is essential for maintaining safety protocols around explosives.
