Section 37 of FA, 1948 : Section 37: Explosive Or Inflammable Dust, Gas, Etc

Explanation using Example

Example Application of Section 37 of The Factories Act, 1948

Imagine a paint manufacturing factory where various chemicals and solvents are mixed to produce different types of paints. These substances can create flammable vapours. To comply with Section 37:

• The factory must ensure that all mixing machinery is properly enclosed to prevent the escape of flammable vapours into the workspace.
• Ventilation systems must be installed to remove or prevent the accumulation of any flammable dust, gas, fume, or vapour produced during the manufacturing process.
• All potential ignition sources, such as open flames, sparks from electrical equipment, or static discharge, must be either removed from the area or properly enclosed to prevent the risk of explosion.

If the factory's equipment is not designed to withstand potential explosion pressures, they must install safety devices like pressure-relief vents to minimize damage in case of an explosion.

Furthermore, if maintenance staff need to open a part of the machinery that has contained flammable gas or vapour, they must first shut off the supply and reduce the internal pressure to atmospheric levels. After maintenance, they must ensure no flammable substances can enter the machinery until it is safe.

Finally, if any welding or similar operations are required on tanks that have held flammable substances, the factory must first clean these tanks to remove all residues and wait until there is no risk of ignition due to high temperatures.
