Read： 659 Time：12months ago Source：Transform the World with Simplicity

Polyester polyols are widely used in the field of chemical production raw materials, but due to their special chemical properties, there are certain safety risks in the process of storage and transportation. In order to ensure the safe storage and transportation of polyester polyols, strict specifications need to be established.

1. Polyester Polyol Hazard

Polyester Polyol is flammable, toxic, corrosive chemicals, the main hazards include:

1. Flammability: Polyester polyol flash point is low, the case of fire, high heat or oxidant contact, there is a risk of combustion and explosion.

2. Toxicity: Polyester polyol has certain toxicity to human body. After contact, it can cause eye, skin and respiratory system irritation. Inhalation of high concentration polyester polyol vapor can cause poisoning.

3. Corrosive: Polyester polyol has a certain degree of corrosiveness, which can corrode materials such as metals and plastics.

2. safe storage specifications for polyester polyols

In order to ensure the safe storage of polyester polyols, the following specifications need to be formulated:

1. The storage place should be dry, ventilated, and cool, away from open flames and heat sources.

2. The storage container shall be well sealed to prevent air and liquid leakage.

3. The storage area should be set up with obvious safety warning signs and equipped with corresponding fire fighting equipment.

4. During storage, the container and its seal should be checked regularly to ensure that it is intact.

5. Staff should wear protective gloves, goggles and other personal protective equipment to avoid direct contact with polyester polyol.

3. safety transportation specification

in order to ensure the safe transportation of polyester polyol, the following specifications need to be formulated:

1. Transportation vehicles should comply with relevant standards and have safety measures such as fire prevention, explosion prevention and leakage prevention.

2. It should be stable during transportation to avoid violent vibration, collision and friction.

3. During transportation, it should be away from fire, high heat and other dangerous sources, and avoid direct sunlight.

4. Transportation personnel should be professionally trained to understand the dangers of polyester polyols and safe transportation knowledge.

5. During transportation, the state of the goods should be checked regularly to ensure that the goods are intact.

4. emergency treatment measures

During the storage and transportation of polyester polyol, in case of accidents, the following emergency treatment measures should be taken:

1. In case of leakage, the leakage source should be cut off immediately, mixed with sand, dry lime or soda ash and recycled to the waste treatment site.

2. In case of fire, the fire source shall be cut off immediately, and fire extinguishers such as foam, dry powder and carbon dioxide shall be used to extinguish the fire.

3. If any person is poisoned, the poisoned person should be immediately moved to a ventilated place to keep the respiratory tract unobstructed and be sent to a doctor for treatment in time.

In short, in order to ensure the safe storage and transportation of polyester polyols, it is necessary to formulate strict regulations, strengthen management and training, and improve the safety awareness and operation skills of staff. At the same time, scientific and effective measures should be taken in emergency situations to ensure the safety of personnel and the environment.
