ABC dry powder fire extinguishing agent can usually be used at high temperatures, but the following points need to be noted:
First of all, the dry powder fire extinguisher should have a safety diaphragm inside, when the internal pressure of the bottle increases due to high temperature, the diaphragm will break to release the pressure, which ensures its safety in a high temperature environment to a certain extent. However, it should be noted that expired fire extinguishers may be at risk of explosion after exposure to the sun, so be sure to check whether the extinguisher is expired before use.
Secondly, although the fire extinguisher can work at high temperatures, long-term exposure to high temperatures or direct sunlight may affect the fire extinguishing agent inside, resulting in poor fire extinguishing effect. Therefore, it is recommended to store fire extinguishers in a cool, dry and easily accessible place.
In addition, when using the ABC dry powder fire extinguishing agent, ensure that the fire extinguisher remains upright and cannot be used horizontally or upside down, otherwise the ABC dry powder may not be able to spray normally. At the same time, it is necessary to avoid spraying equipment such as the human body and electrical appliances to prevent secondary accidents.
Finally, in any case, you should pay attention to your own safety when using the fire extinguisher, if the fire is unsuccessful or the fire reignites, you should immediately evacuate the scene and seek professional help.
In summary, although the ABC dry powder fire extinguishing agent can withstand high temperatures to a certain extent, it is still necessary to pay attention and check its condition before use. Additionally, ensuring that it is operated correctly will guarantee safe and effective fire suppression.
