This section delineates the scope covering storage norms for paints and varnishes with flammable bases, emphasizing safety distances and quantity limits. It mandates rounding values per IS 2:1960 and references IS 1303 and IS 8757 for terminology. Annex A lists related standards. Key tables specify outdoor storage limits detailing maximum container volumes, pile heights, and minimum separation distances to property lines and public ways to ensure fire safety.
Guidelines for selecting factory location include minimum distances from railway sidings depending on locomotive type, proximity to fire brigade (within 5 km), and specifications for main gate dimensions to allow fire appliance access. Storage area lighting must have cables in screwed conduits, protected lamps fixed at least 1 meter above stored goods, and emergency cutouts outside storage. The compound must accommodate manufacturing, storage, utilities, and expansion, kept clear of combustible vegetation.
This section outlines compound size requirements to house manufacturing, storage, and utilities while allowing for future growth. Buildings must adhere to IS 1641 construction standards. Minimum separation of 20 meters is required between residential/office and manufacturing structures. The site must be maintained free of combustible vegetation, ensuring safety and compliance.
Details minimum 20 m separation between residential/office and manufacturing buildings. Construction must comply with IS 1641, using fire-resistant materials. Roofs should be directly supported by walls without intermediate columns, made of lightweight, fire-retardant materials with corrugated iron or asbestos sheets spaced every 6 meters for firefighting access. Roofs must be leak-proof with glazed skylights. Storage areas must prohibit other combustible materials.
Doors must be constructed of non-combustible, fire-resistant materials as per IS 3614 (Part 1), self-closing, and protected against vehicle impact. At least two doors per room are required. Windows in explosion-risk areas should use 3 mm wired glass, open outwards, and have devices preventing inward opening during blasts to enhance safety.
Process tanks must be elevated at least 15 cm above floor level to prevent water ingress during firefighting, constructed from metal with gas-tight sealing. Vents should allow for normal operation and pressure relief during fire, equipped with flame arrestors. Tanks should be surrounded by bunds containing 100% of contents or have drainage to safe burn areas. Metal covers must overlap tank sides by at least 25 mm and be manually closable, preferably with downward flanges for a secure seal.
Tanks should be metal and gas-tight with vents for filling, emptying, and pressure relief during fire. Surround tanks with bunds capable of containing entire contents or provide sufficient drainage to safe burning locations. Tanks exceeding 700 liters or 1 m² in surface area require overflow pipes draining at minimum 900 liters per minute. Drains for tanks over 2200 liters must be manual or automatic, ensuring safe emptying during emergencies.
Cabling in storage areas must be enclosed in heavy gauge screwed conduits. Lamps should be red pendant types protected by well-glass, installed at least 1 meter above the highest stored goods. Emergency cutout switches must be located outside storage areas. Illumination levels vary by area: 20 lux for open compounds, 70 lux in godowns, and 200 lux in processing zones. Wiring complies with IS 1646, using enclosed fittings and switches with remote control switches positioned outside doorways.
Outdoor storage limits are classified by paint/varnish types (Class A, B, C) specifying maximum container volumes, pile heights, and minimum distances between piles, property lines, and public thoroughfares. Indoor storage prohibits any combustible materials besides stored items and requires adequate ventilation to prevent vapor accumulation, especially for liquids with flash points below 26°C. Tank storage must be metal, gas-tight, vented, and protected by bunds or safe drainage.
Storage buildings must be single-storeyed with a maximum height of 10 meters and constructed without combustible flooring unless laid on concrete or masonry. No other combustible materials are allowed within storage sections. Storage quantities and distances follow limits set in Table 1. Tanks within buildings must be metal, gas-tight, vented, and surrounded by bunds or drainage systems.
Drums should be stacked with a maximum capacity of 4500 liters per stack, separated by aisles at least 1.5 meters wide for access and fire prevention. Drums must be stored on their side to prevent ingress of rainwater and corrosion. Buildings require proper ventilation to avoid accumulation of flammable vapors, especially for liquids with flash points under 26°C.
Open storage areas must be securely fenced with restricted access, prohibiting smoking and open flames nearby. Storage quantities and conditions must adhere to prescribed limits, with periodic inspection schedules developed for equipment and safety facilities. Fire prevention measures should be coordinated with local fire authorities, inspected at least monthly, and irregularities promptly addressed.
Hazardous zones must be clearly marked with fire and accident signage. Personal protective equipment including breathing apparatus and fire suits must be provided and maintained. Oil and solvent-soaked waste should be stored in closed metal containers and disposed of at least once per shift. Temperature monitoring must be fail-safe with alarms for excess heat. Fire-resistant building materials, electrical equipment, and adequate firefighting provisions are mandatory.
Ovens must be continuously monitored with automatic temperature control and excess temperature alarms. Interlock systems should shut off heating if preset limits are exceeded. Flames beneath kettles must be shielded unless using electric or muffled furnaces. Lighting of fires must be done from the opposite side of partitions and behind kettles to ensure operator safety.
Dangerous process zones require prominent hazard signage. Breathing apparatus and fire suits should be available for personnel protection. Fire fighting water supply must include hydrants and static tanks, with at least 50% of capacity from static sources located within 180 meters of risk areas. Close coordination with local fire brigades is essential, including regular fire drills and provision of specialized equipment if absent locally.
Frequently Asked

Fire-resistant walls, fire doors, and firefighting access are required to enhance safety.
Buildings must have sufficient ventilation to avoid accumulation of flammable or toxic vapors, especially for liquids with flash points below 26°C. Drum storage outdoors should limit stacks to a maximum of 4500 liters each, with aisles of at least 1.5 meters between stacks for safety and access. Drums must be stored on their side to prevent water ingress and corrosion, preserving container integrity and reducing fire hazards.
Electrical installations in hazardous areas must use flame-proof and dust-proof motors, lighting, and switches in accordance with IS 5572 (Part 1). In storage areas, cables should be enclosed in heavy gauge screwed conduits. Lamps must be red pendant types protected by well-glasses, mounted at least 1 meter above stored goods. Emergency cutout switches should be placed outside storage areas. Wiring must comply with IS 1646, employing enclosed fittings and switches.

Audible alarms should be clearly heard throughout the facility to facilitate prompt evacuation and firefighting response. Temperature monitoring with excess temperature alarms is also advised for early detection.
Tanks must be metal and gas-tight to prevent leakage. Vents should allow normal filling and emptying and safely relieve internal pressure during fire, fitted with flame arrestors. For liquids with flash points under 65°C, vents must discharge outside buildings. All other openings should be securely closed. Tanks larger than 2200 liters require bottom drains for emptying during emergencies, which can be manual or automatic if gravity drainage isn't feasible. Tanks should be surrounded by bunds or have drainage systems to contain spills and reduce fire spread.
