Maximizing Safety: Guidelines for Using Red Phosphorus Flame Retardant & Fire Prevention Measures

I. Precautions for safe use of red phosphorus flame retardant

1. Control the dosage: the adding amount of red phosphorus flame retardant must be strictly controlled, and excessive use may lead to excessive smoke density. Therefore, in the process of use, the appropriate additive amount should be selected according to the nature of the material and the requirements of the processing technology.

2. Avoid contact with skin and eyes: red phosphorus flame retardant has a certain degree of irritation, prolonged contact may cause damage to skin and eyes. Therefore, in the process of use, try to avoid direct contact of skin and eyes with red phosphorus flame retardant. The masterbatch is less affected.

3. Maintain ventilation: Red phosphorus flame retardant is prone to produce dust during use, which may cause harm to the respiratory system if inhaled for a long time. Therefore, good ventilation should be maintained to reduce the concentration of dust. The masterbatch has less influence.

4. Keep away from open fire: Since red phosphorus flame retardant is flammable, it should be kept away from open fire during use to prevent fire accidents.

5. Storage safety: red phosphorus flame retardants should be stored in dry, cool and ventilated places, avoiding direct sunlight and high temperature. Meanwhile, the storage place should be far away from fire source and flammable objects. The storage temperature should not exceed 40℃ and relative humidity should not exceed 80%.

II. Possible fire in the process of mixed use

1. Fire caused by high temperature: red phosphorus flame retardant is easy to burn at high temperature, and if the mixed materials contain flammable substances, it may cause fire during high temperature processing.

2. Fire caused by friction sparks: When red phosphorus flame retardant is mixed with other materials, if friction sparks are generated, it may also cause fire. Therefore, sparks should be avoided as much as possible during the mixing process.

3. Fire caused by residue: If red phosphorus flame retardant is mixed with other materials and left in the equipment or pipeline, it may also cause fire when encountering suitable conditions. Therefore, the equipment should be thoroughly cleaned after use.

III. How to extinguish fire after catching fire

1. Cut off the fire source immediately: If the red phosphorus flame retardant is on fire, cut off the fire source immediately, stop heating or turn off the heat source.

2. Extinguish the fire with fire extinguisher: For small-scale fire, you can use magnesium hydroxide, aluminum hydroxide, dry powder, carbon dioxide and other fire extinguishers to extinguish the fire. The fire should be extinguished by spraying downward from the top of the fire source to give full play to the effect of the fire extinguisher.

3. Extinguish the fire with a large amount of water: For large-scale fires, a large amount of water should be used to extinguish the fire. At the same time, care should be taken to prevent water from entering the interior of the fire source so as not to increase the risk of fire.

4. Seek professional help: If the fire cannot be controlled, call the police immediately and seek help from the professional fire department. While waiting for help, measures should be taken to control the spread of the fire as far as possible.

IV. Conclusion

It is relatively safe to use paste and granular red phosphorus flame retardants.

First of all, paste red phosphorus flame retardant needs to be evenly applied to the surface of the material when used, and attention should be paid to the control of the dosage to avoid over-application leading to overheating of the material and causing fire. In addition, paste red phosphorus flame retardant should avoid contact with open flame and high temperature during storage and use to prevent fire accidents.

Secondly, granular red phosphorus flame retardant needs to pay attention to even mixing when mixing and using to avoid friction and static electricity causing fire. At the same time, attention should be paid to controlling the mixing time and temperature to avoid fire caused by overheating of the material. During storage and use, granular red phosphorus flame retardants should also be kept away from open flames and high temperatures, and well ventilated to minimize dust concentration and respiratory risk.

In conclusion, the safety of the process can be maximized by observing the safety regulations and operating guidelines and using paste and granular red phosphorus flame retardants correctly.
