This code establishes the fire safety practices for tea factories. It details spatial planning, construction features for compartmentation, mitigation of process-specific hazards (like drying and sorting), and the required electrical and fire protection installations.
Code of practice for fire safety of industrial buildings: Tea factories
Quick Reference Values
Fire resistance of separating wallsMinimum 2 hours
Minimum clearance of combustible materials from flues/chimneys500 mm
Maximum travel distance to exit for high hazard areas22.5 m
Practical Notes
Tea dust in the sorting and packing areas is highly combustible and prone to explosion; stringent dust extraction and ventilation systems are mandatory.
Drying sections utilizing hot air furnaces must be structurally isolated from storage and packing areas using fire-resisting walls.
Electrical fittings in dusty zones must be strictly dust-tight to prevent the ignition of airborne tea dust.
