Hot Work Permit: Format, Checklist and Permit-to-Work System for Malls

This guide is for the facility managers, fire officers, fit-out managers and security heads who issue or approve hot work permits in malls. Fit-outs, signage and maintenance jobs bring welding sets and grinders into a building full of shoppers, stock and combustible finishes.

For how tenants raise and route requests, see our mall work permit process guide.

What Is a Permit-to-Work System?

A permit-to-work (PTW) system is a formal written procedure for controlling high-risk work: before the job starts, an authorised person checks the hazards, sets precautions and signs a permit stating what work may be done, where, by whom and for how long.

The UK Health and Safety Executive describes the core elements: the permit states the type of work, names who authorises it, lists precautions taken before work starts (such as isolation and testing), and ends with a formal handback of the area, after which it is filed.

Types of Work Permits

A mall usually has one general permit plus specific permits for higher-risk work, and one job can need several: a welder on an atrium scaffold needs hot work and working at height permits.

• Hot work: flame, sparks or heat (welding, cutting, brazing, grinding). Controls: combustibles cleared, fire watch, extinguishers, detector isolation control.
• Cold work: no ignition source but other hazards, such as plumbing repairs, painting or false ceiling work. Controls: method statement, PPE, isolation where needed, barricading.
• Working at height: atrium light replacement, signage installation, facade cleaning, ceiling void work. Controls: inspected scaffold or MEWP, harness and anchor points, exclusion zone below.
• Confined space: STP tanks, underground water tanks, sumps, manholes. Controls: gas test, ventilation, standby attendant, rescue plan.
• Electrical isolation (LOTO): panel maintenance, tenant DB connection, busduct work. Controls: isolate, lock out, tag out, test dead, authorised electrician.
• Excavation: landscaping, underground services, parking repairs. Controls: service drawings, cable and pipe detection, shoring, barricades.

Cold work permit

In a mall the cold work permit is often merged into the general tenant work permit, with a hot work permit added for any ignition source.

Working at height permit

Set a height threshold in your safety policy; require a permit above it and for any work over a public area. Check the scaffold or platform is inspected and tagged, harnesses tied to a rated anchor, tools tethered and the area below barricaded. No work at height over open trading floors during trading hours.

What Is a Hot Work Permit?

It is the PTW permit for any job that introduces an ignition source. In a mall, treat these as hot work:

• Arc and gas welding, gas and plasma cutting
• Grinding and abrasive cutting with angle grinders
• Brazing and soldering, including copper refrigerant piping for tenant air conditioning
• Torch-applied roofing and waterproofing; heat guns and blow lamps

Take extra care near food court kitchens, where greasy ducts can turn a spark into a fire.

Hot Work Permit Format

Adapt this to your fire safety policy. Each permit covers one location and one shift at most.

Hot Work Permit Checklist

The issuer walks the site with the contractor before signing.

Before work starts

• Is hot work necessary? Consider cold alternatives first: bolting, mechanical cutting, crimped or press-fit pipe joints.
• Combustibles cleared: move combustibles at least 10.7 m (35 ft) from the work, the distance used in the US OSHA welding standard, or cover what cannot be moved with fire-resistant blankets.
• Floor swept; wooden floors wetted or covered.
• Openings sealed: gaps in floors, walls, shafts and ceiling voids covered so sparks cannot travel to the floor below or the store next door.
• Hidden spaces checked: the other side of partitions, false ceilings and ducts inspected for combustibles.
• Extinguishers at the spot: suitable extinguishers and a fire blanket within reach; nearest hose reel confirmed working.
• Fire watch named, trained to use the extinguishers and raise the alarm, and with no other duties.
• Detectors: smoke detectors in the work zone isolated only with the fire control room's agreement, logged with the zone number and time, and restored as soon as the area is safe. Keep sprinklers and hydrants in service.
• Ventilation: fume extraction or ventilation in place, especially in basements and enclosed stores.
• Gas testing where flammable gas or vapour could be present (food court gas lines, DG fuel areas, paint stores, STP areas); do not start unless the reading is within your procedure's limit.
• Equipment: cylinders upright and chained, flashback arrestors fitted, hoses and cables undamaged, welding return lead connected close to the work.
• Public protection: area barricaded with signage; work outside trading hours where possible, following your security SOP for after-hours work.

During the work

• The fire watch stays at the spot, watching the work area and the floor below or beside it where sparks can travel.
• Stop work if conditions change: new materials arrive, the gas detector alarms, or the area cannot be kept clear.
• Keep the permit displayed at the work spot.

Fire Watch: How Long After Hot Work?

A hot work fire can start well after the welder leaves, from smouldering material in a gap, void or duct. Common references:

• US OSHA 29 CFR 1910.252: a fire watch for at least half an hour after welding or cutting is completed.
• NFPA 51B (2019 edition): increased the post-work fire watch to at least one hour, and allows the permit authorising individual to require further fire monitoring of up to three hours after that.
• IS 3016:1982 (Bureau of Indian Standards, code of practice for fire precautions in welding and cutting operations): recommends a hot work permit system, inspection of the site by the person in charge before work (if possible with a fire officer), fire extinguishing equipment within easy reach, and a person other than the welder watching for sparks and hot metal.

Where your state fire service, fire NOC conditions or insurer set no duration, a practical mall standard is a fire watch during the work and for at least 60 minutes after, then a final inspection before the permit is closed and detectors restored. Petroleum installations in India follow their own work permit standard, OISD-STD-105 (Work Permit System).

Roles and Responsibilities

• Requester (tenant's contractor supervisor or mall maintenance supervisor): applies, provides worker and equipment details, keeps precautions in place.
• Permit issuer (facility manager, chief engineer or fire officer): inspects the site, sets conditions, signs and closes the permit after final inspection.
• Area owner (store manager in a unit; operations manager in common areas): releases the area and informs their staff.
• Performer (welder or technician): works within the permit's scope and time; stops if conditions change.
• Fire watch (trained person from the contractor or mall, not the welder): watches for sparks and fire during and after work, uses extinguishers and raises the alarm.
• Fire control room and security: log detector isolation and restoration, track who is working where.

Closing the Permit

1. The performer stops work and removes equipment and cylinders from the area.
2. The fire watch continues for the full post-work period set in your policy.
3. The issuer or a delegate inspects the area, including the floor below, adjacent units and ceiling voids, for heat, smoke or smouldering, and records anything found in an incident report.
4. Isolated detectors are restored and the fire control room confirms the zone is healthy.
5. The issuer signs the closure section with times, and the permit is filed with the work permit record.
6. If the job continues the next day, a new permit is issued after a fresh site check.

The fire safety checklist covers the systems a fire watch relies on; add the permit step to your preventive maintenance checklist for planned hot work.

Managing Hot Work Permits with LazyMonkey

In LazyMonkey Tenant Permits & Approvals, a hot work request can have its own no-code form, with checklist fields, signatures and uploads, and its own approval route, such as operations, then facility, then security. Approvers get reminders, contractors are logged, and every approval is time-stamped in an audit trail.

Conclusion

A hot work permit works when the issuer inspects the site, combustibles are cleared, a dedicated fire watch stays for a defined period after the work, and detectors are restored before closure. Apply the same rules to tenants and in-house teams, and file every permit.
