As an important fire safety equipment, portable fire extinguishers play an indispensable role in various places. Their performance is affected by many factors, among which the temperature of the storage environment is particularly critical. This is not only related to the effectiveness of the fire extinguisher, but also directly affects the safety of personnel and property.
Temperature range of portable fire extinguishers
According to national standards, the applicable temperature range of portable fire extinguishers is usually set at -10℃ to +55℃. Within this range, the performance and service life of the fire extinguisher can be effectively guaranteed. However, if the storage environment exceeds this temperature range, the performance of the fire extinguisher may be significantly damaged or even fail.
Impact of high temperature environment on portable fire extinguishers
High temperature environment has a profound impact on the performance of portable fire extinguishers. The physical principle of thermal expansion and contraction causes the internal pressure of the fire extinguisher to change, which in turn affects the spraying effect. Under high temperature conditions, the extinguishing agent liquid may evaporate, thereby reducing the effective amount of the extinguishing agent, and in severe cases, the fire extinguisher may not be used normally. In addition, high temperature will accelerate the aging of the internal components of the fire extinguisher and shorten its service life. For example, in a car or outdoors in direct sunlight in summer, the performance of a portable fire extinguisher may be significantly affected. Therefore, it is recommended to store it in an environment that avoids direct sunlight and humidity. The ideal storage location should be a ventilated and dry indoor environment to avoid long-term high temperature environment.
The impact of low temperature environment on portable fire extinguishers
The low temperature environment also has a great impact on the performance of portable fire extinguishers. When the ambient temperature drops too low, the fire extinguishing agent may solidify or become viscous, which will directly affect the spraying effect, resulting in poor spraying or shortened spraying distance, thereby weakening the fire extinguishing ability. In addition, under low temperature conditions, the internal parts of the fire extinguisher may increase the internal pressure due to shrinkage, causing potential safety hazards. Therefore, in cold areas or winter, special attention should be paid to the storage temperature of portable fire extinguishers to ensure that they are not affected by low temperatures.
Recommendations for the reasonable storage of portable fire extinguishers
In order to ensure that portable fire extinguishers can perform at their best at critical moments, reasonable storage and regular inspections are essential. Here are some professional suggestions:
Storage environment: Portable fire extinguishers should be stored in a dry, ventilated environment that avoids direct sunlight and humidity. The storage temperature should always be kept between -10℃ and +55℃ to prevent it from exceeding its operating temperature range.
Regular inspection: Regularly check the validity period and service life of the portable fire extinguisher, and pay attention to whether there is damage, rust, etc. on the appearance. At the same time, check the storage status of the fire extinguishing agent to ensure that it can be used normally in an emergency.
Avoid corrosion: Avoid placing the fire extinguisher near substances that may cause corrosion, such as chemicals, to extend its service life.
Installation location: The installation location of the portable fire extinguisher should also be carefully considered, and should be away from heat sources and flammable items to ensure that it can be quickly accessed in an emergency.
