What hazard is created when charges accumulate to the point of an uncontrolled discharge?

• A. Static electricity
• B. Thermal burn
• C. Chemical spill
• D. Noise

Answer: (A)

When static charges build up, they store energy as an electrical potential. If nothing provides a path for that energy to dissipate, the charges will release suddenly in an uncontrolled discharge, shown as a spark. In explosive or flammable environments, that spark can ignite vapors, liquids, or dust, making electrostatic discharge a real ignition source. So the hazard created by charges accumulating to the point of uncontrolled discharge is ignition from a static spark. The other options don’t fit because a chemical spill is related to releasing chemicals, noise is a mechanical/vibrational issue, and a thermal burn is a burn from heat—not the ignition risk posed by a spark in this context.
