Table of Physical and Chemical Properties and Hazardous Characteristics of High Density Polyethylene

Chemical Name:

Chemical Chinese Name: High Density Polyethylene Chemical English Name: Polyethylene CAS No.: 90024

Molecular Formula: [C2H4] n Hazard Code: No Data Hazard Category: No Data UN Number: No Data Hazard Overview

Health Hazard: Its pyrolysis products have a stimulating effect on the respiratory tract. It is essentially non-toxic.

Explosive hazard: This product is flammable.

First aid measures: Skin contact: Remove contaminated clothing and rinse with running water.

Eye contact: Lift the eyelids and rinse with flowing water or saline solution. Seek medical attention.

Inhalation: Remove from the scene to a place with fresh air. Seek medical attention.

Ingestion: Drink plenty of warm water and induce vomiting. Seek medical attention.

Fire protection measures

Hazardous characteristics: When heated, it decomposes and releases flammable gases, which can form explosive mixtures with air.
. Powder can form an explosive mixture with air, and when it reaches a certain concentration, it will explode when it encounters Mars.

Harmful combustion products: carbon monoxide, carbon dioxide.

Fire extinguishing method: Move the container from the fire scene to an open area as much as possible. Extinguishing agent: fog water, foam, dry powder, carbon dioxide, sand.

Emergency response to leakage: Isolate the contaminated area and restrict access. Cut off the fire source. It is recommended that emergency personnel wear dust masks (full face shields) and general work clothes. Avoid dust, sweep carefully, place in a bag and transfer to a safe place. If there is a large leakage, cover it with plastic cloth or canvas. Collect, recycle or transport to a waste disposal site for disposal.

Handling and storage

Precautions for operation: Closed operation. Sealed operation, providing good natural ventilation conditions. Operators must undergo specialized training and strictly follow the operating procedures. It is recommended that operators wear self-priming filter dust masks and chemical safety goggles. Keep away from sources of fire and heat, and smoking is strictly prohibited in the workplace.

Use explosion-proof ventilation systems and equipment. Avoid generating dust. Avoid contact with oxidants. Handle with care during transportation to prevent damage to packaging and containers.

Equip with corresponding types and quantities of fire-fighting equipment and emergency response equipment for leaks. Empty containers may contain residual harmful substances.

Storage precautions: Store in a cool and ventilated warehouse. Stay away from sources of fire and heat. It should be stored separately from oxidants and avoid mixing storage. Equip corresponding types and quantities of fire-fighting equipment. The storage area should be equipped with suitable materials to contain leaked materials.

Contact control and personal protection

TLVTN: No standard established TLVWN: No standard established

Engineering control: Closed operation. Provide good natural ventilation conditions.

Respiratory protection: When the concentration of dust in the air is high, it is recommended to wear a self-priming filter dust mask.

Eye protection: Wear chemical safety goggles. Body protection: Wear general work protective clothing. Hand protection: Wear general work protective gloves.

Other protections: Smoking is strictly prohibited at the work site. Maintain good hygiene habits.
