The first was a furniture factory. The second was a tyre factory. The third specialized in hardware products, including pipes and valves. The fourth was an engineering factory.
According to the published reports, each premises suffered damage estimated at approximately 90 percent.
This figure gives an indication of how destructive the incident was. It also explains why the recovery process could be difficult even though the fire was contained relatively quickly.
A factory is more than the building that houses it. It is a combination of machinery, raw materials, finished products, electrical systems, storage facilities, documents, and equipment needed to operate a business.
When a fire destroys most of a factory, the owners may lose years of investment in a matter of hours.
For a furniture manufacturer, the damage could involve production equipment, timber, upholstery materials, workbenches, and finished furniture awaiting delivery. For a tyre-related business, inventory and specialized storage equipment may represent a substantial portion of its assets.
An engineering business may depend on expensive machinery, tools, components, and technical equipment that cannot easily be replaced.
Even when some items survive the flames, smoke, soot, water, and extreme heat can make them unusable.
This is one reason why fire damage is often more complicated than the visible destruction suggests.
The estimated 90 percent damage should also be understood carefully. It was an early assessment reported by authorities, not a final independent valuation of every business's financial losses.
The precise cost of rebuilding, replacing equipment, restoring production, and compensating affected parties was not established in the initial reports.
Why Industrial Fires Can Become So Destructive
Industrial buildings frequently contain a combination of materials that behave differently when exposed to heat.
Some materials burn readily. Others may not burn easily but can become extremely hot, weaken, or contribute to structural damage.
Storage arrangements can also influence how a fire develops.
For example, combustible goods stacked close together can allow flames to travel from one storage area to another. Packaging materials may provide additional fuel, while machinery and electrical installations can create complicated firefighting conditions.
A fire that begins in one section may therefore spread through several connected areas before emergency crews can establish effective control.
The arrangement of neighboring premises is equally important.
When factories share boundaries or are separated by relatively narrow access routes, a fire can expose nearby structures to radiant heat, flames, and burning debris.
Industrial fire safety therefore requires more than installing extinguishers inside individual buildings. It also involves planning how buildings are separated, how emergency vehicles gain access, and how water can be supplied during a major incident.
The Puchong fire demonstrated the consequences that can occur when an emergency spreads beyond its original premises.
It also highlighted the importance of early detection, clear evacuation procedures, and coordinated emergency response.
The Risk of Roof Collapse After a Major Fire
One of the most concerning details reported by firefighters was the possibility of roof and structural collapse.
This danger can remain even when the flames are no longer spreading.
Industrial buildings often use large roof structures supported by steel frames, columns, beams, and connecting components. These systems are designed to carry specific loads under normal operating conditions.
During a major fire, however, intense heat can change the mechanical properties of structural materials.
Steel, for example, loses strength and stiffness as its temperature rises. Connections can become weakened, roof components may deform, and supporting elements can be damaged.
Concrete can also suffer deterioration when exposed to severe heat. Depending on the temperature and duration of exposure, sections may crack, lose strength, or experience surface damage.
The resulting structure may look relatively stable from outside while containing hidden weaknesses.
This creates a serious risk for firefighters and anyone who might enter the premises.
For that reason, emergency personnel must assess the condition of a damaged building before attempting further operations inside it.
A roof that appears intact may still be at risk of falling. A wall that has survived the fire may have lost part of its ability to support surrounding elements.
The concern reported in Puchong was therefore not merely a technical detail. It was a central part of the emergency operation.
Even after the fire was brought under control, firefighters needed to remain alert to structural hazards while extinguishing remaining flames.
Why Firefighters Continue Working After Flames Disappear
Many people assume that a fire emergency ends once the visible flames have disappeared.
In reality, this is often only one stage of the operation.
Inside a heavily damaged factory, pockets of heat can remain beneath collapsed roofing, inside storage areas, behind walls, or among piles of debris.
Materials may continue smoldering without producing large visible flames.
If these hot spots are not identified and extinguished, they can potentially ignite surrounding combustible materials again.
Firefighters therefore carry out inspections and cooling operations to reduce the possibility of rekindling.
The process can be particularly difficult when roofs have collapsed or when the interior is filled with damaged equipment and debris.
Water must be directed carefully, while crews must avoid entering areas that may be structurally unstable.
In Puchong, firefighting operations continued around the roofs and inside the affected premises after the blaze had been brought under control.
This additional work was essential to ensure that the emergency did not develop into another fire.
The incident also illustrates why emergency crews cannot simply leave a scene immediately after the most dramatic part of a fire has ended.
Their responsibility includes ensuring that the remaining hazards are properly managed.
Chapter 3: What Could Have Caused the Puchong Factory Fire?
One of the biggest questions following the incident was how the fire started.
When a major industrial fire destroys several buildings, people naturally want to know whether it was caused by an electrical fault, machinery failure, careless handling of combustible materials, or another problem.
However, the initial reports did not establish the cause.
The Selangor Fire and Rescue Department stated that the cause of the blaze remained under investigation. It would therefore be premature to identify a particular machine, employee, electrical installation, or business as responsible.
Understanding the possible causes is nevertheless important because industrial fires can develop through several different mechanisms.
1. Electrical Faults and Overloaded Installations
Electrical problems are among the hazards that industrial facilities must manage carefully.
Factories frequently operate machinery, ventilation systems, lighting, compressors, pumps, computers, and other equipment simultaneously.
If electrical installations are poorly maintained, damaged, incorrectly installed, or operated beyond their intended capacity, they may create dangerous conditions.
Possible problems include deteriorating insulation, loose electrical connections, damaged cables, short circuits, and overheating components.
A loose connection, for example, can generate heat over time. If combustible materials are stored nearby, an electrical problem may become an ignition source.
Electrical faults do not automatically mean that a fire will occur. Proper circuit protection, maintenance, inspection, and safe operating procedures can significantly reduce the risk.
However, they remain an important area for investigators to examine after a factory fire.
In a case involving multiple premises, investigators may need to determine whether the fire originated in one building before spreading to neighboring structures or whether more than one ignition source was involved.
That determination requires physical evidence and technical examination.
2. Machinery and Industrial Equipment
Factories use machinery that can operate for long periods under demanding conditions.
Motors, bearings, electrical control systems, cutting equipment, heating devices, and other components may generate heat during normal operation.
When equipment is poorly maintained, friction, overheating, mechanical failure, or electrical malfunction can create additional hazards.
For example, a damaged bearing may generate excessive heat. A motor that is not properly ventilated may overheat. Equipment used for cutting or grinding can also produce sparks.
Industrial operators therefore need preventive maintenance programs that identify developing problems before they become emergencies.
Regular inspections should not be treated as unnecessary expenses. They are part of protecting workers, equipment, buildings, and neighboring businesses.
3. Combustible Materials and Storage Conditions
Another important consideration is the way materials are stored.
A furniture factory may contain timber, foam, fabrics, adhesives, and packaging. A tyre-related facility may hold rubber products and other materials associated with manufacturing or distribution.
