Choosing Fire Extinguishers for Confined Spaces

Working in confined spaces presents a higher fire risk due to restricted access, limited ventilation, and the potential presence of flammable gases, liquids, or electrical equipment. Such fire situations may result in the rapid spread of flames and smoke and make evacuation difficult. It is important to choose the right fire extinguishers for confined spaces to prevent a small fire from escalating into a major emergency.

Which Fire Extinguisher Should be Used in a Confined Space?

The type of fire extinguisher required depends on the fire hazards identified during the confined space risk assessment.

CO₂ Fire Extinguisher – Suitable for electrical fires as it does not conduct electricity and leaves no residue.
Dry Chemical Powder (DCP) Fire Extinguisher – Recommended for Class A, Class B, Class C, and electrical fires, making it a versatile choice for many confined space environments.

Always ensure the selected fire extinguisher is appropriate for the specific hazards present in the work area.

Steps to follow Before Attempting to Fight a Fire in Confined Space

Only attempt to tackle a fire if it is small, safe to approach, and you have received appropriate fire extinguisher training. If there is any doubt, evacuate immediately.

Ensure the confined space is adequately ventilated.
Raise the fire alarm immediately to alert others.
Only trained and competent personnel should use a fire extinguisher.
Always keep a clear escape route in case you need to evacuate.

Important Safety Reminders

When responding to a fire in a confined space, always put personal safety first.

Never use water on electrical or flammable liquid fires.
Leave the area immediately if the fire begins to spread or smoke levels increase.
Call the emergency services if the fire cannot be controlled safely.
Never put yourself at risk to protect equipment or property.
Follow your organization’s emergency procedures and evacuate without delay when instructed.
