As temperatures drop and heaters fire up across the country, the risk of fire-related incidents rises significantly. Whether you manage a business premises or are a homeowner keen on protecting your property, ensuring your fire extinguishers are fully operational during the colder months is a vital part of winter preparedness.

In this blog, we’ll explore how to keep your fire extinguishers winter-ready this November, the risks posed by seasonal changes, and what steps you can take to maintain a safe environment.

Why Fire Extinguisher Readiness Matters in Winter

During winter, several fire hazards become more prevalent:

• Increased use of heating equipment, such as space heaters and open fires.

• Overloaded electrical systems from festive lighting and electric blankets.

• Blocked ventilation due to closed windows and insulation.

• Reduced attention to safety due to holiday distractions or reduced staff cover.

These risks make it more important than ever to ensure that your fire extinguishers are ready for action, properly maintained, and fit for purpose.

1. Check That Extinguishers Are Serviced and Compliant

British Standards recommend that fire extinguishers be serviced by a competent technician at least once a year. November is an ideal time to arrange this if your annual service is due or overdue.

At Fireline UK, our BAFE-registered technicians provide thorough maintenance checks, including:

• Pressure gauge readings

• Valve and seal inspection

• Condition of hoses and nozzles

• Weight and date verification

• Tamper tag and wall bracket checks

Fire extinguishers that show signs of corrosion, leakage, or damage should be replaced immediately.

2. Store Fire Extinguishers at the Correct Temperature

Most fire extinguishers are designed to operate in environments where the temperature remains above -5°C, though some models require warmer conditions. During winter, especially in unheated areas like garages, outbuildings or storage units, extinguishers may become too cold to function properly.

Foam and water-based extinguishers are particularly vulnerable to freezing, which can block internal mechanisms or rupture the cylinder.

To prevent this:

• Ensure extinguishers are installed in temperature-controlled areas.

• Use anti-freeze models in colder settings where necessary.

• Avoid leaving extinguishers in vehicles overnight in freezing weather.

3. Reassess Fire Risks in Your Building

Fire risk assessments should be reviewed regularly, and November is a logical time to update yours to reflect winter-specific risks.

Ask yourself:

• Are portable heaters in use, and are they kept away from flammable items?

• Are extension leads being overloaded with festive lighting?

• Have escape routes been kept clear of seasonal decorations or obstructions?

An updated fire risk assessment will help determine whether your current fire extinguisher provision is still appropriate for your premises.

4. Confirm the Location and Visibility of Fire Extinguishers

During winter, workspaces may be rearranged to accommodate seasonal stock or heating equipment. It’s important to make sure this doesn’t obstruct access to fire extinguishers.

Make sure all extinguishers:

• Are wall-mounted or in stands

• Have clear signage above them

• Are easily visible and accessible at all times

• Have not been moved without updating your fire safety plans

Even temporary storage items such as Christmas trees, boxes or portable heaters can block extinguisher access if not carefully placed.

5. Provide Refresher Fire Safety Training

Colder months often coincide with new or temporary staff members joining businesses. Take time in November to offer a refresher fire safety course or demonstration for your team.

This should include:

• How to identify different types of fire extinguishers (water, foam, CO₂, dry powder)

• When and how to use each extinguisher type safely

• What to do if a fire breaks out

• Your building’s evacuation procedure

Training not only boosts confidence but can also prevent panic in an emergency.

6. Test Your Fire Alarm System

While this blog focuses on extinguishers, it’s worth remembering that your entire fire protection system should be reviewed in winter. A working fire alarm provides vital early warning and helps people act quickly.

We recommend testing your alarm weekly and checking:

• Battery backup function

• Sounder volume in all areas

• Detection units are dust-free and unobstructed

If your alarm hasn’t been serviced recently, now is the time to book a professional check.

Winter Safety Is About Preparation

Fires don’t take a holiday. In fact, fire-related callouts often increase during winter, especially in December and January. Staying ahead of seasonal risks by keeping your fire extinguishers winter-ready is not only a legal requirement for businesses, but a common-sense measure for all property owners.

By staying proactive, arranging professional servicing, and reviewing safety measures, you’ll be giving yourself peace of mind that should the worst happen, your premises is prepared.
