RST: Storage Mistakes That Spark Fires – How to Handle Flammable Materials Safely

When it comes to fire safety, few risks are as underestimated as improper storage. Warehouses, factories, and even office environments often contain materials that can ignite easily under the wrong conditions: cleaning solvents, fuels, aerosols and paper products. Although these products are highly flammable, with the right systems and awareness in place, the risk can be significantly reduced. At RST Risk and Security Solutions, we’ve seen how small oversights in storage and handling can lead to devastating fires. This guide explores the most common mistakes that spark fires, and how your business can prevent them.

1. Mixing Incompatible Materials

One of the most dangerous storage errors is keeping incompatible chemicals or substances too close together. For example, oxidisers and flammable liquids can react violently if spilled or exposed to heat, while acids and bases can cause hazardous fumes or combustion.

How to prevent it:

• Store chemicals according to compatibility groups.

• Use separate, clearly-labelled storage areas for flammables, corrosives, and oxidisers.

• Keep safety data sheets (SDS) easily accessible for all stored materials.

2. Poor Ventilation in Storage Areas

Flammable vapours from paints, fuels, or cleaning agents can accumulate in enclosed spaces, turning one spark or static discharge into a major fire.

How to prevent it:

• Ensure all flammable storage areas are well ventilated.

• Avoid storing such materials in basements or confined rooms.

• Use explosion-proof lighting and electrical fittings in designated flammable areas.

3. Overcrowding and Blocked Exits

In many workplaces, storage areas become overfilled with boxes, drums, and equipment, making it difficult to maintain clear walkways or fire exits. In an emergency, this can delay evacuation and fire suppression efforts.

How to prevent it:

• Adhere to safe stacking and spacing limits.

• Maintain a clear 1-metre clearance around fire extinguishers, exits, and control panels.

• Conduct regular housekeeping inspections to identify and remove clutter.

4. Ignoring Temperature Control

Flammable liquids and gases can become unstable when stored in high temperatures or direct sunlight. Even office supplies like aerosols and adhesives can pose a risk if exposed to heat.

How to prevent it:

• Keep flammable materials away from heat sources such as boilers, heaters, or sunlight.

• Use temperature-controlled storage cabinets for volatile substances.

• Monitor ambient temperatures, especially in warehouses and metal containers.

5. Using Improper Containers or Labelling

Transferring materials into unmarked or inappropriate containers is a recipe for confusion and disaster. Employees may unknowingly mix incompatible substances or mishandle unknown liquids.

How to prevent it:

• Always store flammable materials in approved containers.

• Label all containers with the correct name, hazard symbol, and handling instructions.

• Train staff to recognise and interpret hazard labels and pictograms.

6. Neglecting Fire Suppression Systems

Even the best storage practices need backup protection. Inadequate or poorly maintained fire suppression systems can allow a small incident to escalate rapidly.

How to prevent it:

• Install fire detection and suppression systems suitable for your storage environment.

• Regularly test and service fire extinguishers, sprinklers, and alarms.

• Train all personnel on fire response protocols and extinguisher use.
