Section 3. Hazards identification

Primary routs of entry: inhalation, ingestion

Health hazards: effect on the skin, causing dermatitis, acne, folliculitis, phototoxic dermatitis, toxic dermatosis, hernia, and cancer, causing nasal septal injury.

Environmental hazards: harmful to the environment and causing pollution to the atmosphere.

Explosion hazard: flammable, where vapors mix with air to form explosive mixtures.


Section 4. First aid measures

Skin contact: remove contaminated clothing and rinse thoroughly with soapy water and water. If you feel uncomfortable, seek medical advice.

Eye contact: lift the eyelid and rinse with running water or saline solution. If you feel uncomfortable, seek medical advice.

Inhalation: get out of the scene quickly and into the fresh air. Keep the airways open. If you have difficulty breathing, give oxygen. call

Inhalation, cardiac arrest, immediately cardiopulmonary resuscitation. Go to a doctor.

Injection: drink water, if you feel uncomfortable, make stomach wash as soon as possible, seek medical advice.


Section 5. Fire-fighting measures

Hazardous characteristics: Its vapor and air can form an explosive mixture, and can easily burn and explode in case of fire or high heat, violent reaction when contacting with oxidants. In case of high heat, the internal pressure of the container increases, causing cracking and explosion.

Specific hazards during fire-fighting: Carbon monoxide, carbon dioxide.

Fire-fighting methods: Firefighters must wear a filter-type gas mask (full face mask) or an isolated respirator, wear a full-body fire-resistant and protective clothing, and extinguish the fire in the upwind direction. Move the container from the fire as far as possible to the open space. The water spray keeps the fire container cool until the fire is over. If the containers in the fire are discolored or produce sound from the safety pressure relief device, they must be evacuated immediately.

Extinguishing agents: water spray, foam, dry powder, carbon dioxide, sand.

Precautions for fire extinguishing: Do not spray water directly on the melt, as this may cause serious drooling or severe boiling.


Section 6. Accidental release measures

Emergency action: Rapidly evacuation of personnel from leaking contaminated areas to safe areas, and isolation, strict restrictions on access. Cut off the fire. It is recommended that emergency personnel wear self-contained positive pressure breathing apparatus and wear protective clothing. Cut off the leak as much as possible. Prevent restricted space such as sewers and flood drains. A small amount of leakage: Adsorption or absorption with sand or other non-combustible materials. A lot of leaks: constructing embankments or digging pits for containment, covered with with foam to reduce vapor disasters. The pump is transferred to a tanker or a dedicated collector for recovery or transport to a waste disposal site for disposal.


Section 7. Handling and storage

Handling instructions: Closed operation, full ventilation, operators must be specially trained to strictly observe the operating procedures. It is recommended that operators wear self-priming filter-type gas masks (full face masks), wear protective clothing, and wear rubber-oil resistant gloves. Keep away from fire and heat sources and smoking is prohibited in the workplace. Use explosion-proof ventilation systems and equipment. Prevent vapors from leaking into the workplace air. Avoid contacting with oxidants. It should be lightly loaded and unloaded to prevent damage to the packaging and containers. Equipped with the appropriate types and quantities of fire-fighting equipment and emergency response equipment. Empty containers may leave harmful residues.

Storage precautions: Store in a cool, ventilated warehouse. Keep away from fire and heat sources. Keep away from oxidizer, not storing together. Use explosion-proof lighting and ventilation facilities. Do not use mechanical equipment and tools that are prone to sparks. Storage areas should be equipped with spill emergency treatment equipment and suitable containment materials.


Section 8. Exposure controls/personal protection

Protective measures: Enzi's viscosity method, extraction method, distillation method, burning method

Engineering measures: The production process is closed and fully ventilated. Provide safety showers and eyewash equipment.

Respiratory protection: When the concentration in the air exceeds the limit, a self-priming filter gas mask (full face mask) must be worn. Emergency resuscitation or evacuation should be done with an air respirator.

Eye protection: Protection from respiratory protection.

Skin and body protection: Wear protective clothing.

Hand protection: Wear rubber oil resistant gloves.

Other protection: Smoking is strictly prohibited on the job site. After work, take a shower. Pay attention to personal hygiene.
