When can spark-generating tools be used near explosives?

• A. Never use any spark-generating tools near explosives.
• B. Use spark-generating tools as needed for efficiency.
• C. Use spark-generating tools only if approved.
• D. Use spark-generating tools without approval in an emergency.

Answer: (C)

Sparks can ignite explosive vapors or dust, so any use of spark-generating tools near explosives must be governed by an approved plan. The approval process ensures a proper risk assessment, defined safe conditions, and trained personnel, with appropriate controls or alternatives in place. When such authorization is in effect, tools are used only under those specified conditions; without approval, the ignition risk is too great.
