What is the required fire resistance for a load-bearing wall in a paint factory?

4 hours, as per Table 2 of the code.

What is the minimum distance required between a solvent storage tank and the factory's boundary wall?

30 meters, according to Table 1.

What kind of electrical installations are needed in a mixing area?

All electrical equipment must be of flameproof construction suitable for the specific hazardous atmosphere, as specified in Clause 8.

What is the maximum travel distance to a fire exit?

The travel distance to an exit shall not exceed 22.5 m for high hazard areas (Clause 5.4.3).

Practical Notes

Strict adherence to hazardous area classification (zoning) is crucial for selecting appropriate electrical equipment (flameproof, intrinsically safe) to prevent ignition.

Controlling static electricity through proper earthing and bonding of all equipment, containers, and personnel is a primary safety measure during solvent transfer and mixing operations.

Effective ventilation is non-negotiable to prevent the build-up of flammable vapours to explosive concentrations.
