Fire Safety Systems: Alarm, Sprinklers, Hydrants & Evacuation

Fire safety is the first thing a serious buyer auditor checks in a garment factory, and for good reason. A garment factory concentrates everything a fire needs: tonnes of fabric and cartons as fuel, dust and loose cuttings as kindling, electrical load from hundreds of machines, and hundreds or thousands of workers on one floor. When a fire starts in such a building, the difference between a contained incident and a tragedy is rarely the fire itself — it is the system around it. Did the alarm sound everywhere? Did workers know two ways out? Were the exits clear? Had the drill ever covered their shift?

This lesson treats fire safety as a system of five links: detection, alarm, suppression, evacuation, and maintenance. If any link fails, the chain fails. A factory can own expensive sprinklers and still fail if the hydrant pump has been out of service for three months without a repair record. It can run perfect drills on the day shift and still fail if the night shift has never evacuated. Build all five links, test them honestly, and record everything — that is what keeps workers alive and what satisfies the strictest SEDEX, WRAP, or buyer audit.

Detection is the first link. Manual call points — the red break-glass boxes — must be reachable on every floor and in every large section, so any worker can raise the alarm in seconds. Automatic detection covers the hours when nobody is watching: smoke detectors in stores, offices, and false ceilings, and heat detectors in kitchens, boiler rooms, and dusty areas where smoke detectors would false-alarm. The alarm panel must show which zone triggered, so the fire team goes to the right place instead of searching the building.

Alarm audibility is where many factories fail quietly. An alarm that is clear in the office may be inaudible over cutting machines, and a night shift with fewer supervisors may miss a single sounder. Test audibility in the noisiest sections — cutting, generator rooms, washing plants — and add sounders and flashing beacons where the alarm cannot be heard or seen. Test the alarm on a fixed day every month, rotating zones, and log the date, zones, tester, and any defect. An auditor trusts a boring, regular log far more than a perfect-looking log written the week before the audit.

Automatic sprinklers are the most effective single fire protection in a garment factory because they work without human action, including at night. A standard wet-pipe system holds water under pressure behind closed sprinkler heads; heat from a fire opens only the heads near the fire, releasing water directly onto it. This is why sprinklers control most factory fires before they spread — they attack the fire at its source while workers evacuate.

Sprinklers only work if three conditions hold: the control valves are open, the pump and water reserve are functional, and the heads are unobstructed. A pallet stacked against a sprinkler head, a valve closed after maintenance and never reopened, or a pump that has not run in months each silently defeats the system. Check valve positions weekly, run the pump on schedule per the system manual, and keep storage clear of sprinkler heads. Verify sprinkler coverage, head spacing, and water supply requirements against the current building code and buyer standard for your building type — do not guess these numbers, because they depend on occupancy, ceiling height, and hazard classification.

Hydrants and hose reels give trained fire teams water to fight a fire that sprinklers have not controlled. Test hydrant points under pressure on a schedule, confirm hoses are complete with nozzles attached, and keep access permanently clear — a hydrant behind a carton stack is not a hydrant. Record pressure readings and repair any failing point immediately with a dated record; an auditor will ask what happened to the point that failed last quarter, and "we fixed it" without evidence is not an answer.

Portable extinguishers are for trained workers attacking a small fire in its first minute. The right type matters: water and foam for ordinary combustibles such as fabric and paper, dry powder for flammable liquids and electrical fires, and carbon dioxide for electrical equipment. Check every extinguisher monthly — pressure gauge in the green zone, pin and seal intact, service tag in date, access clear — and send units for professional service as the manufacturer and code require (verify the current interval; it varies by type and jurisdiction). Train workers in their own sections on the extinguishers kept there. An untrained worker will not touch an extinguisher during a real fire, and an auditor knows it.

Every workstation needs two escape routes, because smoke or fire may block the first. Routes must be wide enough for the number of workers using them, kept permanently clear, signposted with glowing exit signs, and lit by emergency lighting that works when power fails. Staircases are the critical bottleneck: protect them with self-closing fire doors, never store anything in them, and never prop their doors open. Final exits must open outward easily, without keys, codes, or special knowledge — and they must never be locked, bolted, or chained, not for security, not for stock, not for five minutes.

Assembly points sit outside the building, far enough from falling debris and clear of fire vehicle access. Assign fire wardens for every floor and every shift, including nights, and give them visible identification and a headcount list. Workers with mobility difficulties need a personal evacuation plan, agreed in advance, not improvised during an alarm. Walk the routes yourself at night: a route that looks fine at noon may be dark, locked, or blocked at midnight.

A drill is a test, not a ceremony. Announced drills on the day shift, where everyone strolls to the assembly point, prove almost nothing. Run drills on every shift, including nights and overtime hours, and run at least one unannounced drill each year so the result is honest. Time the drill floor by floor — from alarm to last worker at the assembly point — and record attendance, timing, and every observation: blocked routes, dark stairs, inaudible alarms, wardens who were absent.

Then close the loop. Every observation becomes a corrective action with an owner and a deadline, and the next drill re-tests it. A drill report filed without fixes is worse than useless: it proves the factory knew about a failure and ignored it. Brief workers after each drill on what went well and what will change, so drills build confidence instead of cynicism. When a real alarm sounds, workers should move with the calm of people who have done this before — because they have.

Fire safety evidence is a single pack, not a drawer of loose papers: the fire risk assessment, equipment layout drawings, inspection and service logs, drill reports with corrective actions, training records, and the fire team roster for every shift. Review the pack monthly with the compliance manager, the maintenance head, and HR, and treat any gap as an open finding with a deadline.

Common audit findings tell the same story everywhere: extinguishers past service date, hydrant points with no pressure record, drills missing the night shift, exits used as storage, and fire team members who left the factory months ago but still appear on the roster. Each of these is cheap to fix and expensive to explain. Verify every numeric requirement — extinguisher spacing, hydrant pressure, travel distances, drill frequency — against the current national building code and the buyer's standard that applies to your factory, and write the source of each number into your procedures so the next safety officer does not have to guess.

Walk your factory this week with this list. Is every exit clear, unlocked, and signposted? Does the alarm reach the noisiest section? Are hydrant pressures logged and extinguishers in date? Has every shift drilled, including nights? Is the fire team roster current? If any answer is no, you have found your next corrective action — and you have found it before an auditor or a fire did.
