Electrostatic Hazards
| Electrostatic hazard | Ways to overcome |
|---|---|
| Lightning | Thunderclouds are charged by friction between the water molecules in the thunderclouds and air molecules. It then ionises the air and the ionised air provides a conducting path for electric charge to be discharged to the nearest or sharpest obkect on the ground. Lightning conductors on buildings which provide a conducting path for electrons in the air allows safe discharge to the ground. |
| Fires due to sparks caused by sudden electrostatic discharge | Excess charges on a petrol tanker flow safely through a metal chain to the ground. Synthetic rubber tyres which contains graphite to aid in electric discharge to the ground |
| Damage to electronic equipment | Store electrical componenets in antistatic packaging (metallised film) |
