Read： 925 Time：13months ago Source：Transform the World with Simplicity

TEP (triethylphosphoric acid) is a commonly used raw material for chemical production. Due to its corrosive and toxic properties, it is necessary to strictly comply with relevant safety regulations during storage and transportation. This article will detail the safe storage and transportation specifications of TEP.

1. the physical and chemical properties of TEP

TEP is a colorless and transparent liquid with a pungent odor. It is flammable, explosive and highly corrosive. When TEP vapor is mixed with air, it may form an explosive mixture, which may cause combustion and explosion when exposed to open flame and high heat. Therefore, during storage and transportation, special attention needs to be paid to its safety.

2. TEP storage specification

1. The storage place should choose a cool, ventilated and dry place, away from fire and heat sources.
2. The storage container must be sealed and no leakage is allowed. Storage containers shall be regularly inspected for safety to ensure that they are in good condition.
3. The storage area shall be provided with obvious safety warning signs, and equipped with corresponding fire-fighting equipment and leakage emergency treatment equipment.
4. The storage process should keep the temperature below 30 ℃, avoid direct sunlight.

3. TEP transportation specifications

1. Transport vehicles should comply with relevant standards, with explosion-proof, fire-proof, anti-leakage and other functions. The condition of the vehicle should be checked before transportation to ensure safety and reliability.
2. Keep running smoothly during transportation to avoid severe vibration, collision and friction.
3. Transport personnel should be professionally trained and familiar with the nature of TEP and safe operation procedures.
4. During transportation, traffic rules shall be strictly observed to avoid illegal acts such as speeding and overloading.

4. TEP Leakage Emergency Treatment

1. If a leak is found, the operation should be stopped immediately, and the leakage source should be closed to prevent the leakage from spreading.
2. Mix with sand, dry lime or soda ash and recycle to the waste treatment site for disposal.
3. When there is a large amount of leakage, embankment or pit shall be built and covered with foam to reduce steam disaster. Transfer to tank truck or special collector with explosion-proof pump, recycle or transport to waste treatment site for disposal.

5. protection measures

engineering control: strictly airtight, provide sufficient local exhaust or full ventilation. Mechanized and automated operation as much as possible. It is recommended that the operator wear self-priming filtering gas mask (half mask), chemical safety goggles, anti-poison penetration overalls and rubber oil-resistant gloves. Keep away from fire and heat sources. Smoking is strictly prohibited in the workplace. Use explosion-proof ventilation systems and equipment. Prevent vapor leakage into the workplace air. Avoid contact with oxidants and acids. Particular care should be taken to avoid contact with water. Handle lightly to prevent damage to packaging and containers. Equipped with corresponding types and quantities of fire fighting equipment and leakage emergency treatment equipment. Empty containers may leave harmful substances.

6. first aid measures to

skin contact: immediately remove contaminated clothing and rinse with plenty of flowing water for at least 15 minutes. Seek medical attention.
eye contact: immediately lift the eyelid, with plenty of flowing water or saline rinse thoroughly for at least 15 minutes. Seek medical attention.
inhalation: quickly leave the scene to fresh air. Keep the airway unobstructed. If breathing is difficult, give oxygen. If breathing stops, give artificial respiration immediately. Seek medical attention. Ingestion: Gargle with water and drink milk or egg white. Seek medical attention.

In short, in the field of chemical production raw materials, the safe storage and transportation of TEP is very important, and the relevant regulations and operating requirements must be strictly observed to ensure the safety of personnel and the environment.
