Cleaning liquids may be used in an explosive area under what condition?

• A. When safe for the environment
• B. When weather conditions permit
• C. When authorized by a TO
• D. Only under direct supervision

Answer: (C)

In an explosive area, using cleaning liquids is allowed only when someone with authority explicitly approves it. This is because liquids can release flammable vapors, react with energetic materials, or leave residues that could ignite or cause detonation if not properly controlled. The approval must come from the Technical Officer (TO), who evaluates the specific liquid, the task, and the safety controls in place—such as ventilation, elimination of ignition sources, proper PPE, spill containment, and procedures for safe handling. This authorization ensures the cleaning is necessary and conducted under documented, safe conditions. Environmental concerns, weather, or being under supervision alone do not guarantee safety in these environments; they don’t address chemical risk and required controls. Authorization by the TO is the protective step that ensures all risks are considered and managed before cleaning liquids are used.
