Can Fire Extinguishers Explode? What Circumstances Could Lead to an Explosion? All these questions will be answered in the article below.
Important Notes When Using Fire Extinguishers
Can Fire Extinguishers Explode?
You may not know that fire extinguishers typically contain high-pressure gas. For CO2 extinguishers, the pressure ranges from 80 to 120 bar. Under normal temperature conditions, these gases are safe. This is why it is essential to store extinguishers in a cool environment and avoid direct sunlight. This principle is crucial for proper storage. However, there are still instances where fire extinguishers can explode. So, what are the causes?
High Temperatures
If you keep up with the news, you may have noticed an increase in incidents of fire extinguishers exploding. Manufacturers have also issued numerous warnings about this phenomenon. Most often, the cause of these explosions is high temperatures or improper placement of the extinguishers.
Manufacturer warnings about safe temperature factors on fire extinguishers.
Most fire extinguishers can withstand temperatures up to 55 degrees Celsius. However, when the outdoor temperature reaches 40 degrees Celsius, the greenhouse effect can raise the temperature inside a vehicle to around 60 degrees Celsius. Additionally, the plastic dashboard absorbs heat, making the temperature in that area rise to 70-80 degrees Celsius. This level exceeds the tolerance of many fire extinguishers, thus significantly increasing the risk of explosion.
Improper Placement of Extinguishers
As mentioned earlier, if you are wondering whether fire extinguishers can explode, the answer is yes. To minimize this risk, it is crucial to place the extinguishers correctly. In areas exposed to direct sunlight, the temperature can rise significantly. Therefore, you should avoid placing extinguishers in these areas as it could lead to explosion risks.
Using Low-Quality Fire Extinguishers
One of the main causes of fire extinguishers exploding is the use of low-quality products. Using subpar extinguishers can diminish their firefighting effectiveness and may result in unfortunate incidents or even casualties.
Proper Use of Fire Extinguishers
Do not place fire extinguishers in direct sunlight.
After understanding whether fire extinguishers can explode, you should also be aware of some essential notes for their usage to maximize their effectiveness, especially during emergencies. Here are the important points to consider when using fire extinguishers:
What to Avoid
- Do not place fire extinguishers in areas exposed to direct sunlight, especially on dashboards, under the rear windshield, or in A-frame areas, as these spots often exceed 50 degrees Celsius.
- Avoid using fire extinguishers without a verified origin, as this may impact their firefighting capability.
Recommended Practices
It is advisable to place fire extinguishers inside vehicles, prioritizing locations within the driver’s reach. This allows the driver to react quickly in case of an emergency. Ideal spots include under the driver’s seat or beside the front passenger’s footwell. Of course, ensure that the extinguisher does not obstruct the driver’s movement.
- If placing the extinguisher outside, ensure it is in an accessible location, while keeping it out of reach of children.
- Regularly check the fire extinguisher to familiarize yourself with its operation and verify its expiration date.
- Select the correct placement for the fire extinguisher, especially when positioned outside, ensuring proper spacing.
If you still have questions about whether fire extinguishers can explode, the answer is yes. Such incidents can occur, but they typically arise from improper usage.
