Fire Extinguishers

Did you know that in the UK, studies show around 60% of businesses never fully recover after a serious fire? Downtime, lost revenue, soaring insurance premiums, and massive rebuilding costs often lead to permanent closure within months or a couple of years. Portable fire extinguishers are your frontline weapon against small fires. When used correctly by trained staff, they can extinguish a blaze in its early stages—often before it spreads and causes widespread damage—preventing a minor incident from becoming a catastrophic event that endangers lives, premises, and livelihoods. Recent surveys highlight their effectiveness: up to 93% of fires are successfully put out using portable extinguishers, reducing the need for fire service call-outs and saving millions in economic losses and preventing injuries. When combined with a reliable fire alarm system, regular fire risk assessments, staff training on extinguisher use, clear evacuation procedures, and optional 24/7 monitoring, properly maintained and compliant fire extinguishers dramatically reduce the risk of a small fire escalating into a business-crippling disaster.

UK fire classes (per BS EN 3 and the updated BS ISO 3941:2026) include:

  • Class A — Solid combustibles (wood, paper, textiles, plastics)
  • Class B — Flammable liquids (petrol, diesel, oils, solvents)
  • Class C — Flammable gases (propane, butane)
  • Class D — Combustible metals (magnesium, aluminium — specialist only)
  • Class F — Cooking oils and fats (commercial kitchens, deep fat fryers)
  • Class L (new in BS ISO 3941:2026) — Lithium-ion battery fires (e.g., in EVs, e-bikes, UPS systems, power tools, solar storage, or device charging areas). These involve thermal runaway, re-ignition, and toxic gas release; standard agents often fail to fully suppress them.

Selection must follow a site-specific fire risk assessment (mandatory under the Regulatory Reform (Fire Safety) Order 2005) and BS 5306-8. Common commercial choices:

  • Dry powder (blue label, e.g., 13A:89B:C or higher) for multi-purpose coverage (A, B, C, electrical).
  • Foam (cream label) or water-based (red label) for A and B risks.
  • CO₂ (black label) for electrical and Class B (no residue).
  • Wet chemical (yellow label) for Class F in catering areas.

For premises with lithium-ion hazards (e.g., warehouses, offices with EV fleets, data centres, or retail with charging stations), supplement with specialist lithium-ion rated extinguishers (e.g., AVD — Aqueous Vermiculite Dispersion — or water-based cooling types). True Class L-rated portables are emerging; consult your risk assessor or competent technician for compliance.

Use the PASS technique:

  • Pull the pin (twist to break the tamper seal).
  • Aim low at the base of the fire.
  • Squeeze the handle to discharge.
  • Sweep side to side.

Only trained staff should use extinguishers on small, contained fires (e.g., no larger than a waste bin, no risk of escalation or blocking escape). Under the Regulatory Reform (Fire Safety) Order 2005, the Responsible Person must ensure suitable firefighting equipment is provided and that staff receive basic training. If the fire spreads, produces heavy smoke, or endangers escape, evacuate immediately, close doors, activate the alarm, and call 999. For Class L (lithium-ion) fires, prioritise evacuation and cooling with water-based agents if safe (disconnect power/charger first); re-ignition is common—alert the fire service early.

Per BS 5306-3 (the UK code of practice):

  • Monthly — The Responsible Person (or nominated staff) must conduct visual checks: confirm pressure gauge in green/charged zone, pin/seal intact, no damage/corrosion/leaks, accessible/unobstructed, correctly signed.
  • Annually — A competent technician (e.g., BAFE SP101-registered) must perform a full basic service: inspection, pressure test, partial discharge if needed, certification, and tag update.
  • Extended service/overhaul — Every 5 years for most types (water, foam, powder, wet chemical); CO₂ often 10 years. Hydrostatic testing or replacement follows manufacturer specs (typically 10–20 years total life).

Any use (even partial) requires immediate professional recharge/service. Records must be kept on-site for audits/enforcement. Non-compliance risks fines or enforcement notices under the Regulatory Reform (Fire Safety) Order 2005.

Positioning follows BS 5306-8 and your fire risk assessment:

  • Along escape routes and near high-risk areas (kitchens, workshops, electrical rooms, storage with flammables).
  • Maximum travel distance typically 30–50 m (depending on hazard level; often one per 200 m² floor area as a guide).
  • At least two Class A-capable units per floor/level as a minimum.
  • Mounted 1–1.5 m from floor (handle height), clearly visible, unobstructed, with appropriate signage.
  • Not in locked cupboards or behind doors.

For lithium-ion risks (Class L), place near charging stations or battery storage with suitable agents. The Responsible Person must review placement after changes (e.g., new equipment or layout). Professional commissioning on-site is required for new installations.

Recharge or replace immediately if:

  • Used (even partially).
  • Pressure gauge not in green zone.
  • Pin/seal missing, broken, or tampered.
  • Visible damage, corrosion, leaks, or dents.
  • Past service intervals (missed annual basic service, or extended service due per BS 5306-3).

Most units last 5–10+ years with proper care, but condemn if parts unavailable, severe corrosion, or UV/plastic degradation occurs. For specialist Class L units, follow manufacturer guidance closely. Always use a competent technician—better to inspect/replace proactively than risk failure during an incident.
