Warehouse Fire: Water, Bales and a Blocked Exit
At a plastic-recycling warehouse in Aba, 14 workers are sorting bales when a burning smell comes from a wall-mounted electrical distribution board. A small flame and white smoke appear at the panel. One roll-up exit is blocked by stacked bales; the other opens into a narrow alley. There is no fire alarm or evacuation plan. A 9-litre water extinguisher and a 6-kg ABC dry-powder extinguisher are mounted near the office, but the powder unit's gauge is in the red and its hose is cracked. The supervisor shouts, 'Throw water on it before it spreads - water is free.' A new worker runs toward the panel with a bucket. Two workers are still working near the bales at the back, wearing ear defenders, and cannot hear the shouting. The warehouse holds 3 tonnes of PET bales and 200 litres of cleaning solvent in unlabelled drums near the office.
1. What is the correct immediate response, and why is water the wrong choice?
Read the worked answer
Raise the alarm, tell everyone to leave by the clear exit, call the fire service and account for all 14 workers at a safe assembly point. The two workers in ear defenders must be physically alerted. If the panel can be isolated safely, do it; otherwise keep away. This is an electrical fire with nearby combustible bales and solvent drums, so water from a 9-litre extinguisher is dangerous: it can conduct electricity back to the user and spread burning solvent. The correct first-aid firefighting medium, only if the fire is small and a trained person has a clear escape route, is CO2 or ABC dry powder. The ABC unit is unreliable because the gauge is in the red and the hose is cracked; it should not be used until serviced. The priority is evacuation and calling the fire service, not saving bales. The bucket carrier should be stopped and the area kept clear.
2. Which fire-safety deficiencies should be corrected, and in what order?
Read the worked answer
First, restore two clear escape routes and remove the bales blocking the roll-up door; this is an immediate life-safety fix. Second, provide a working alarm and a simple evacuation plan with assembly point, roll call and drills. Third, service or replace extinguishers, mount them accessibly and train selected staff. Fourth, move the 200 litres of cleaning solvent to a labelled, ventilated store away from ignition sources and fit secondary containment; the unlabelled drums are a serious hazard. Fifth, improve housekeeping and separate electrical equipment from bales. Sixth, add emergency lighting and a way to alert workers wearing hearing protection. The order reflects life safety first, then fire prevention and containment, then administration. The supervisor's 'water is free' instruction should be corrected in training, not repeated.
3. What should the post-incident review cover?
Read the worked answer
The review should establish how the fire started, why the panel fault was not detected, who was at risk, why one exit was blocked and why the alarm was absent. It should check the extinguisher inspection records, the solvent storage arrangements, housekeeping, worker training and the emergency response. It should also examine the supervisor's instruction and the new worker's dash toward the panel, because both show a culture problem. Actions should be assigned with owners and dates: clear exits, alarm, extinguisher service, solvent store, electrical inspection, evacuation drill and training. The findings should be shared with the workforce and the fire service where appropriate. Disciplinary action alone would not fix the blocked exit or the unlabelled drums; the system changes are the real corrective actions.
