Equipment Used to Put Off the Fire: A Comprehensive Guide

Fire incidents rarely start as “big fires.” Most begin as small fires caused by everyday risks—overloaded plugs, poor housekeeping, flammable liquids stored incorrectly, or kitchen fires that flare up fast. The difference between a close call and a major loss often comes down to two things: the right fire extinguisher for the hazard and equipment that is inspected, accessible, and supported by trained personnel. The right equipment is essential to quickly and effectively extinguish fires and prevent them from spreading. Every facility needs a clear plan for fighting fires and a reliable suite of equipment used to put off the fire. This guide is intended for facilities managers, safety officers, and anyone responsible for fire safety in commercial or industrial settings.

For facilities teams managing malls, warehouses, office blocks, parking garages, and industrial settings, fire safety equipment is not a “nice to have”—it’s part of business continuity, insurance expectations, and legal duty of care. In South Africa, building fire protection requirements (including portable fire extinguishers) link back to standards like SANS 1910 and servicing requirements under SANS 1475-1, with equipment expected to be installed and maintained by competent persons. Fire suppression equipment must also be capable of performing under extreme temperatures to ensure reliability in all fire scenarios. (SANS10400 Building Regulations)

“Portable fire extinguishers installed in a building shall comply with the requirements in SANS 1910, and shall be installed, maintained and serviced by competent persons…” (SANS10400 Building Regulations)

Introduction to Fire Safety

Fire safety is fundamental to safeguarding lives, property, and the environment from the devastating effects of fire. Effective fire safety involves a combination of preventive strategies, reliable fire safety equipment, and well-rehearsed emergency procedures. Key tools such as fire extinguishers, fire blankets, and fire sprinklers are essential for combating fires and containing them before they escalate. Fire extinguishing equipment includes handheld extinguishers, hose reels, hydrants, and fire blankets. Understanding the different types of fires—such as class A fires (ordinary combustibles), class B fires (flammable liquids), class C fires (electrical equipment), class D fires (combustible metals), and class F fires (cooking oils and fats)—is crucial for selecting the correct fire extinguisher and other fire safety equipment. By identifying potential fire hazards and equipping your facility with the right safety equipment, you can significantly reduce the risk of a fire emergency and ensure a swift, safe response if one occurs.

Fire Risk Assessment

A fire risk assessment is a structured process designed to identify and evaluate potential fire hazards within a facility. This assessment involves pinpointing sources of ignition, fuel, and oxygen that could contribute to a fire, as well as analyzing how likely a fire is to occur and what the consequences might be. It also reviews the effectiveness of current fire safety measures, such as fire extinguishers, emergency lighting, and fire alarms, and highlights areas where improvements are needed. Conducting a thorough fire risk assessment enables organizations to proactively address fire safety, reduce the likelihood of injury or property loss, and ensure compliance with fire regulations. Regular assessments are a cornerstone of responsible fire safety management, helping to keep people and assets protected.

Fire Prevention

Fire prevention is a proactive approach to fire safety that focuses on stopping fires before they start. This means implementing robust safety protocols, such as proper storage and handling of flammable liquids, routine maintenance of electrical equipment, and comprehensive fire safety training for all staff. Fire prevention also requires vigilance in identifying and addressing potential fire hazards, including combustible materials, electrical hazards, and sources of heat. By taking these steps, organizations can minimize the risk of fire, protect their workforce and assets, and maintain a safe, compliant environment. Effective fire prevention not only reduces the chance of a fire emergency but also helps avoid costly disruptions and damage.

Fire Safety Starts With Matching “Types of Fire” to “Extinguisher Types”

Before we talk equipment, align on the basics: different fires need different extinguishing agent choices. If you use the wrong extinguisher on the wrong fire, you can make the fire emergency worse—especially with electrical hazards and energized equipment. (OSHA)

A practical way to think about this is “fuel type”:

• Class A fires: ordinary combustibles (paper, wood, cloth, many plastics)
• Class B fires: flammable liquid fires (petrol, solvents, oils)—fires involving flammable liquids
• Class C fires: electrical equipment (energized electrical fires)
• Class D fires: combustible metals (e.g., magnesium, titanium)—burning metals
• Class F: cooking oils/fats—burning oil, deep fat fryers, chip pan fires, commercial kitchen risks (some regions use “Class K” for similar kitchen fires)

In some classification systems, Class C fires refer to gas fires. Fighting class C (gas) fires requires shutting off the gas supply and using appropriate extinguishing agents, such as dry powder, and personnel should be trained to recognize and safely handle gas fire situations.

Guidance and classification references vary slightly by region, but the principle is consistent: choose the correct fire extinguisher for the hazard. When selecting an extinguisher, always check the fire rating to ensure it is suitable for the specific fighting class and fire hazard. (IFSEC Global)

Right Fire Extinguisher Selection (Fast Reference Table)

Use this as a quick “first pass” when planning coverage for a building, tenant area, plant room, or kitchen.

Fire Risk / Scenario	Fire Class	Recommended Equipment	Notes
Cardboard, paper stores, general office, packaging	Class A	Water extinguishers / some foam extinguishers	Avoid on energized electrical equipment
Fuel store, solvents, paints, workshop liquids	Class B	Foam extinguishers, some dry powder extinguishers	Controls surface fires involving flammable liquids
DB boards, server racks, control panels	Electrical / Class C	Carbon dioxide fire extinguisher (CO₂)	Good for electrical fires; beware re-ignition, confined spaces
Commercial kitchens, canopies, hoods, oils/fats	Class F fires	Wet chemical extinguisher	Designed for cooking oil fires; reduces re-ignition via chemical action
Specialized metal machining / powders	Class D	Specialist metal extinguishers	Standard ABC/dry chemical may not be appropriate

Fire Blankets

Fire blankets are simple, fast “human intervention” tools for smothering small fires—particularly in kitchens or for a situation where clothing catches fire.

Where fire blankets help most:

• Small pan flare-ups (before they become full cooking oil fires)
• Clothing fires (wrap and smother, then treat burns)
• Small bin or bench-top fires where you can safely cover the combustion zone

Practical placement tips:

• Install near (but not directly above) cooking equipment so you can reach it without moving toward a heat source.
• Ensure the packaging instructions are visible and the blanket can be pulled free quickly.
• Train staff on when to use a blanket vs. when to evacuate and call the fire department.

Fire blankets do not replace a wet chemical extinguisher in commercial kitchens—especially around deep fat fryers—but they can prevent a minor incident from escalating when used early and correctly.

Carbon Dioxide Fire Extinguisher

A carbon dioxide fire extinguisher is a go-to option for fires involving equipment because CO₂ does not leave powder residue on sensitive electronics. It works by displacing oxygen supply around the flame zone (and cooling slightly at discharge).

Best use-cases:

• Server rooms, comms cupboards, control panels
• Workshops with energized equipment
• Office electrical fires where shutting power is not immediate

Key cautions:

• Confined spaces: CO₂ displaces oxygen—use carefully and ventilate.
• Re-ignition risk: if the underlying heat source remains, the fire starts again once the gas disperses.
• Always keep an exit behind you. If smoke builds, evacuate.

---

Class F Fires and the Wet Chemical Extinguisher

Class F fires (cooking oils/fats) behave differently from Class A and Class B because oils can retain heat and re-ignite easily, even after flames appear “out.” That’s why the class F wet chemical extinguisher is essential in commercial kitchens to extinguish fires.

Wet chemical is designed for:

• Cooking oil fires (including olive oil and other high-risk oils)
• Deep fat fryers
• Busy food prep areas where grease accumulation increases risk

The wet chemical agent knocks down flames, cools the burning oil, and forms a sealing layer that helps prevent re-ignition. (Safequip Pty Ltd)

If your facility has multiple tenants (food courts, cafeterias, canteens), this is often where “most likely fire starts” meets “highest disruption cost.”

---

Dry Powder Extinguishers and Dry Chemical

Dry powder extinguishers (often ABC) are popular because they cover multiple risks. They work by smothering and interrupting the chemical chain reaction—helpful across mixed areas where you may face Class A, Class B, and electrical-related incidents. (Safequip Pty Ltd)

Where they fit well:

• Plant rooms
• Warehouses with mixed combustible materials
• General industrial settings with varied ignition sources

Where to be careful:

• Highly sensitive electronics (powder cleanup + potential damage)
• Visibility-limited areas (powder clouds can reduce visibility during evacuation)
• Confined spaces (respiratory irritation)

Dry chemical is effective, but it’s not a “one-extinguisher-solves-everything” answer—especially when you have specialist risks like kitchens or combustible metals.

Fire Sprinklers and Fire Suppression Systems

Portable firefighting equipment is important, but it relies on a person being present, trained, and willing to act. Fire sprinklers and fixed fire suppression systems respond automatically—often controlling a fire before it spreads beyond the room of origin.

NFPA’s research on home fire sprinklers shows significant reductions in average property loss when sprinklers are present in reported home fires. (NFPA)

Reported home fires with sprinklers present show substantially lower average property loss compared to similar fires without sprinklers. (NFPA)

In commercial contexts (warehouses, malls, industrial sites), fixed systems can include:

• Wet pipe sprinkler systems
• Deluge systems for high-hazard areas
• Kitchen hood suppression systems (critical for cooking oil risks)
• Clean agent systems for sensitive server environments (where appropriate)

The operational rule is the same: design to the hazard, inspect regularly, and keep records.

Fire Safety Equipment Installation

Proper installation of fire safety equipment is vital for ensuring that your facility is prepared to combat fires and support safe evacuation during a fire emergency. Fire safety equipment—including portable fire extinguishers, fire sprinklers, emergency lighting, and other safety equipment—should always be installed by trained personnel who understand both the equipment and the relevant fire safety regulations. Each type of equipment, from water extinguishers and foam extinguishers to dry powder extinguishers and carbon dioxide fire extinguishers, is designed to tackle specific types of fires. Adhering to manufacturer instructions and industry standards during installation, followed by regular inspections and maintenance, ensures that all fire safety equipment remains in optimal working condition and ready for use when needed.

Fire Safety Signs

Fire safety signs are a critical part of any fire safety strategy, providing clear guidance and essential information during a fire emergency. These signs must be highly visible, easy to interpret, and compliant with current standards and regulations. Fire safety signs indicate the locations of fire safety equipment such as fire extinguishers and alarms, mark emergency exits, and provide instructions for using safety equipment and evacuating safely. By ensuring that fire safety signs are properly placed and maintained, organizations can help prevent confusion and panic, enabling staff and visitors to respond quickly and effectively in the event of a fire. Clear signage is a simple yet powerful tool for supporting overall fire safety and minimizing risk.

Fires Involving Electrical Equipment

Electrical fires are hazardous because the risk is not just flame, it’s energized conductors, arc faults, and the possibility of the extinguishing material becoming electrically live if the wrong unit is used. (OSHA)

Here are the controls you want in place to reduce the risk of electrical fires:

• Routine inspection of plugs, extension leads, and DB boards
• Housekeeping around panels (no storage blocking access)
• Correct extinguisher nearby (often CO₂)
• Clear shutdown procedure for isolating power where safe

In high-value environments like data centers, it’s also worth planning for smoke management and ensuring emergency lighting and exit routes remain visible. Electrical fires and lithium ion fires are some of the most important risks you need to mitigate in our data driven future.

Fighting Fires With Procedure, Not Panic

Equipment alone is not enough. Effective fire safety measures combine:

• Accessible equipment (visible signage, correct mounting)
• Training (who uses what, when to evacuate)
• Drills (routes, muster points, responsible person roles)
• Maintenance and inspections (proof it works before you need it)
• Regular training and drills are essential for ensuring that personnel can effectively use fire extinguishers in an emergency.
• Emergency lighting and exit or evacuation signs guide occupants to safety.
• Establish a safe evacuation route during a fire emergency.

A simple decision rule many safety bodies emphasize: only attempt to extinguish if the fire is small, you have a clear exit, and emergency services have been called or are being called. (Red Cross) If a fire extinguisher fails to put out a fire, you must get to safety immediately and call emergency services.

Use a fire extinguisher only if the fire is small, you have a clear escape route, and conditions (like smoke) aren’t making the room unsafe. (Red Cross)

Fire Safety Equipment Inspection and Compliance Records

For facilities managers and procurement teams, inspections are where compliance becomes defensible.

In South Africa, portable extinguishers are expected to comply with SANS requirements and be installed/maintained/serviced by competent persons. (SANS10400 Building Regulations) Standards-based guidance also references servicing intervals and periodic pressure testing requirements by extinguisher type. (Fire Safe)

What to log:

• Inspection dates and findings (monthly / routine)
• Service dates (annual servicing as required)
• Pressure testing schedules (where applicable)
• Replacements (expired, damaged, discharged units)
• Staff training attendance and drill records
• Monitoring and management of hazardous substances stored near combustible materials to prevent re-ignition and ensure safety

Final Checklist (Use This for Monthly Walkthroughs)

• Fire extinguishers accessible: Not blocked by stock, furniture, or locked doors
• Correct extinguisher type per area: Kitchens have wet chemical; electrical rooms have CO₂; mixed risks have appropriate units
• Pressure and tamper seals: Gauge in green (if applicable), pin and seal intact
• Condition and signage: Labels readable, bracket secure, signage visible
• Fire blankets (where installed): Correct placement, packaging intact, staff know how to deploy
• Fire doors: Not wedged open; closes properly; signage intact
• Emergency lighting / exit routes: Clearly visible, functioning, no obstructions
• Fire hoses / buckets (if present): In good condition, accessible, correct for site plan. Fire buckets are a simple, portable firefighting tool used for Class A and B fires, but are less effective on large fires or certain fire types.
• First aid kit / aid kits: Stocked for minor injuries, burn care basics present
• Records up to date: Inspection log, service certificates, training records filed
