For 3% and 6% foaming agents, the main difference lies in their use occasions and differences in effects. When dealing with a relatively obvious fire with a strong combustion source, it is recommended to use 6% foaming agent, because its higher concentration can control the fire more quickly and form a protective layer to effectively protect the safety of the surrounding environment.
In some small or relatively simple fire situations, you can choose to use 3% foaming agent, because its cost is lower and it is more convenient to use. At the same time, according to different foaming agent concentrations, the required operating procedures and injection methods are also different. When using 6% foam liquid, it needs to be fully pre-mixed before operation, and a higher pressure is used to achieve spraying to achieve a better fire extinguishing effect. When using 3% foam agent, a relatively simple spraying method can be adopted, and the operation can often be completed with a foam gun. It should be noted that when using different concentrations of foaming agent, its dosage also needs to be adjusted accordingly to ensure that it achieves the expected chemical flame retardant effect while avoiding waste and unnecessary loss. It is recommended to carry out sufficient understanding and training before choosing a foam agent and operating it to ensure the safety and effect of use.
