Part 3: Hazard Overview

Category: Invasion route: Skin, eye contact, inhalation, ingestion. Health hazards: Its pyrolysis products have a stimulating effect on the respiratory tract. It is essentially non-toxic. Environmental hazard: Does not decompose in soil. Explosive hazard: This product is flammable.

Part 4: 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.

Part 5: Fire Protection Measures

Hazardous Characteristics: When heated, it decomposes and releases flammable gases that can form explosive mixtures with air.
. Powder can form an explosive mixture with air, and when it reaches a certain concentration, it will explode upon contact with 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.

Part 6: Emergency Response to Leakage

Emergency Response: Isolate the leakage 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 up 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 waste disposal sites for disposal.

Part 7: Handling and Storage

Precautions for Handling: Sealed Handling.
. Sealed operation, providing good natural ventilation conditions. Operators must undergo specialized training and strictly adhere to 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 with corresponding types and quantities of fire-fighting equipment. The storage area should be equipped with suitable materials to contain leaked materials.
