Q. Show the Sources of Ignition?

Sources of Ignition - Possible sources of ignition include the following:

• Electrical: Sparks or arcs may occur when current carrying contacts are separated or through static electricity discharge.

• Naked Lights: e.g. fired heaters, fires, smoking, hot work, or gas welding

• IC Engines: Spark-ignition systems or exhaust hot spots.

• Spontaneous Combustion: Pyrophoric materials or vapour leakage at temperatures above AIT.

• Frictional Ignition: Grit blasting, power tool grinding or mechanical failure of rotating machinery.

• High Temperature Surfaces: Transfer lines, HP steam lines or other hot surfaces.
