Knowing how to use a fire cylinder correctly can prevent a small fire from turning into a life-threatening emergency.
Many homes and workplaces own fire safety equipment, but very few people understand how to operate it safely under pressure.

This guide explains, step by step, how to use a fire cylinder, with a clear demonstration approach based on the Safepro 4.5kg CO2 fire cylinder.
By the end, you will know when to use it, how to use it, and how to stay safe while doing so.

What Is a Fire Cylinder and How Is It Used?

A fire cylinder is a pressurised fire safety device that releases a fire-suppressing agent to control or extinguish a fire at its early stage.
When used correctly, it cuts off oxygen or heat from the fire, stopping it from spreading before emergency services arrive.

CO2 fire cylinders are commonly used for electrical and flammable liquid fires because they leave no residue and do not conduct electricity.

Technical Details of a Fire Cylinder

These technical characteristics make a fire cylinder suitable for indoor and residential environments.

When Should You Use a Fire Cylinder?

A fire cylinder is designed for early-stage fires only.
Using it at the right moment is critical for safety.

Common applications include:

• Electrical panel or wiring fires
• Computer, server, or appliance fires
• Kitchen fires involving oils or gas
• Home offices and inverter areas
• Retail counters and small commercial spaces

If the fire is spreading rapidly or producing heavy smoke, evacuate immediately instead of using a fire cylinder.

Understanding the Safepro CO2 Fire Cylinder Before Use

Before operating any fire cylinder, you should understand its basic parts:

• Safety pin
• Discharge horn or hose
• Pressure-sealed cylinder body
• Operating handle

The Safepro 4.5kg CO2 fire cylinder is compact and designed for easy handling, making it suitable for homes and small workplaces.

Step-by-Step: How to Use a Fire Cylinder Safely

Step 1: Assess the Situation

Ensure the fire is small and contained.
Check that you have a clear exit behind you.

Step 2: Pull the Safety Pin

This unlocks the operating handle of the fire cylinder.

Step 3: Aim at the Base of the Fire

Never aim at flames.
Always target the base where the fuel source is.

Step 4: Squeeze the Handle

This releases the CO2 gas from the fire cylinder.

Step 5: Sweep Side to Side

Move the discharge horn slowly across the base until the fire is out.

Stop once the fire is fully extinguished and back away carefully.

The PASS Technique Explained for Fire Cylinder Use

The PASS technique is a simple way to remember how to use a fire cylinder.

• P – Pull the pin
• A – Aim at the base
• S – Squeeze the handle
• S – Sweep side to side

This method reduces panic and ensures correct usage during emergencies.

Safety Precautions When Using a Fire Cylinder

Using a fire cylinder incorrectly can be dangerous.
Always follow these safety guidelines:

• Stand at a safe distance from the fire
• Never touch the CO2 discharge horn with bare hands
• Avoid using CO2 in confined spaces without ventilation
• Do not turn your back on the fire immediately

These precautions help prevent injury while using a fire cylinder.
