Which extinguisher is appropriate for use on flammable gases?

The blue powder extinguisher is designed specifically for use on flammable gases, among other fire types. These extinguishers typically contain a dry chemical agent, such as sodium bicarbonate or potassium bicarbonate, that effectively smothers flames and interrupts the chemical reaction fueling the fire. This makes them particularly effective in situations involving flammable liquids and gases, where other types of extinguishers might not work as effectively or could potentially exacerbate the fire.

In contrast, cream foam extinguishers are better suited for flammable liquids, while carbon dioxide extinguishers are ideal for electrical fires and some flammable liquids, but they may not be effective on flammable gases due to their mechanism of operation. Yellow wet chemical extinguishers are tailored for cooking oils and fats, making them ineffective for gas fires. Understanding the correct type of extinguisher for different fire scenarios is crucial for effective fire safety and management.
