Burning and explosion hazard: This product supports combustion and is narcotic.

Part IV First Aid Measures

skin contact:

eye contact:

Inhalation: quickly leave the scene to a place with fresh air. Keep the airway open. If breathing is difficult, give oxygen

gas. If breathing stops, give artificial respiration immediately. Seek medical attention.

Ingestion:

Part Five Fire Prevention Measures

Hazardous characteristics: It can assist combustion when it meets with flammable gas such as ether and ethylene, which can intensify the flame burning. Hazardous combustion products: nitrogen oxides

Fire fighting method: This product is non-flammable. Firefighters must wear gas masks and full-body firefighting suits to put out the fire in the upwind direction.

Use water mist to keep the containers in the fire area cool. Cut off the power supply quickly, and cut off the gas with water spray protection

The personnel of the source, then select the appropriate extinguishing agent to extinguish the fire according to the cause of the fire.

Part VI Emergency Response to Leakage

Emergency action: Quickly evacuate personnel from the leaked contaminated area to the upper wind, and isolate them, strictly restrict access. build

It is recommended that emergency response personnel wear self-contained positive pressure breathing apparatus and general work clothes. Cut as much as possible

Source off. Reasonable ventilation to accelerate diffusion. Leaking containers should be properly handled, repaired and inspected before

use.

Part VII Handling and storage

Handling precautions: closed operation. Airtight operation provides good natural ventilation conditions. operator

Must undergo special training and strictly abide by the operating procedures. Keep away from fire, heat, and workplace

Smoking is strictly prohibited. Keep away from flammable and combustible materials to prevent gas from leaking into the workplace air. avoid

Contact with reducing agent. Lightly load and unload during transportation to prevent damage to cylinders and accessories. Equipped with corresponding products

Types and quantities of fire-fighting equipment and leakage emergency treatment equipment.

Precautions for storage: Store in a cool, ventilated warehouse. Keep away from fire and heat sources. The storage temperature should not exceed 30℃.

It should be stored separately from easily (combustible) materials and should not be mixed. The storage area should be equipped with leakage emergency treatment equipment

Prepared.

Part VIII Exposure Control/Personal Protection

Maximum allowable concentration: China MAC (mg/m3): 5[NO2] Former Soviet Union MAC (mg/m3): no standards have been established Monitoring method: Naphthalene ethylenediamine hydrochloride colorimetric method

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

Respiratory system protection: Generally, no special protection is required. Self-contained filter gas masks (half

Face mask).

Eye protection: Generally, no special protection is required.

Body protection: wear general work clothes.

Hand protection: Wear protective gloves for general work.

Other protection: Avoid high concentration inhalation. When entering the tank, restricted space or other high-concentration areas, someone must be supervised.
