Water extinguishers are specifically designed for Class A fires, which involve combustible materials like paper, wood, textiles, and some plastics. These extinguishers are effective for fires fueled by solid materials, making them a straightforward choice for common fire situations. They are also the most widely used and cost-effective type of extinguisher available.
A dry powder fire extinguisher is the most effective option for combating fires, as it interrupts the chemical reaction that fuels the blaze. Foam and CO2 extinguishers are also safe alternatives, as they smother the fire by cutting off its oxygen supply. It's important to note that using water on a Class B fire is extremely dangerous and should be avoided.
For a Class C fire, which involves flammable gases or electrical equipment, it's best to use a dry powder extinguisher or a CO2 extinguisher. Both of these types are effective because they do not conduct electricity and can safely extinguish the fire without posing additional risks. Always ensure the extinguisher is suitable for electrical fires before using it.
Distance and Accessibility: Fire extinguishers should be located within 30 meters of any point in a workplace where there is a risk of fire. In high-risk areas, such as kitchens or workshops, extinguishers may need to be more accessible.
Height and Mounting: Extinguishers should be mounted on a wall or in a cabinet so that the operating instructions are visible. The top of the extinguisher should not be more than 1.5 meters above the floor.
Visibility: Extinguishers must be clearly marked and easily identifiable. If they are not immediately visible, appropriate signage should indicate their location.
Unobstructed Access: There should be no obstructions blocking access to fire extinguishers, ensuring they can be reached quickly in an emergency.
Regular Inspection: Fire extinguishers must be inspected and maintained annually by a competent person, in accordance with the UK Fire Safety Order 2005 and relevant British Standards (BS 5306).
Specific Codes: Always follow guidance from the Regulatory Reform (Fire Safety) Order 2005 and consult local fire authorities for specific requirements and recommendations.
