What is the correct handling rule for open flames in blast areas?

• A. Open Flames Are Prohibited
• B. Open Flames Allowed With A Permit
• C. Open Flames Allowed During Daylight
• D. No Restriction

Answer: (A)

Open flames must be eliminated in blast areas because these zones can contain flammable gases or coal dust released by blasting. A flame, even a small one, can ignite those atmospheres and cause a dangerous explosion or fire. That’s why the rule is a strict prohibition on open flames in blast areas. Permits, daylight, or no restriction would not remove the ignition risk, since any flame or spark in the area could ignite the vapors or dust. Keeping open flames out is the essential safety measure to prevent ignition sources where blasting is involved.
