HAZARDS IDENTIFICATION:

This substance is nonflammable

ROUTE OF INFECTION:

Inhalation, ingestion, skin and eye contact

HEALTH   HAZARDS :

Single acute overexposure:

Inhalation: Due to low volatility, there is little chance of vapor inhalation at room temperature. One contact can't be dangerous.

Eye contact: Can cause mild temporary eye irritation. It does not cause corneal damage.

Skin contact: Long time contact can cause mild skin irritation, irritation areas become red.

Skin absorption: percutaneous absorption of a prolonged skin contact will not exceed the harmful amount.

Chronic, chronic or repeated overexposure

Other overexposure effects:  Data currently unavailable.

ENVIRONMENTAL HAZARDS :

Low toxicity to water environment.

DANGER OF EXPLOSION:

Exposure to open flame or high temperature can cause combustion or produce toxic high temperature vapor.

INHALATION:

The product is not volatile. Under special circumstances, such as fire, smoke or aerosols are inhaled and quickly leave the site to fresh air to keep the respiratory tract unobstructed. If breathing is difficult, give oxygen: if breathing stops, give artificial respiration immediately. When respiration and heartbeat stop, perform artificial respiration and cardiac compression immediately and seek medical advice.

IF SWALLOWED:

Do not let the unconscious person take anything orally and do not induce vomiting. Rinse your mouth and get medical attention immediately.

SKIN CONTACT:

Take off contaminated clothes immediately, wash with plenty of flowing water for at least 15 minutes, and seek medical advice

EYE CONTACT:

Lift the eyelids immediately and wash them thoroughly with a large amount of flowing water or normal saline for at least 15 minutes; Get medical attention.

DANGEROUS CHARACTERISTICS:

This substance is nonflammable.

HAZARDOUS COMBUSTION

PRODUCTS

It will form toxic vapor or smoke in case of open fire or high temperature.

FIRE EXTINGUISHING METHOD:

Fire fighters must wear full body fire retardant clothing, wear positive pressure self-contained breathing apparatus, and fight fire upwind.

If possible, move the container away from the fire and into the open. Spray water to keep the fire container cool until the end of the fire. If the container in the fire is discolored or generates sound from the safety relief device, it must be removed immediately.

Extinguishing agent: soluble foam, carbon dioxide, dry powder, water mist.

HANDLING:

Strengthen ventilation. Operators must be specially trained. Smoking is prohibited in the workplace. Avoid static electricity during operation. Avoid contact with eyes and skin, and wash thoroughly after operation. Handle with care to prevent damage to packaging and containers. Appropriate leakage emergency treatment equipment and appropriate materials shall be provided.

STORAGE:

Keep the container closed and store it in a cool and ventilated warehouse. The handling temperature is 10-38 ℃ . The storage area shall be equipped with leakage emergency treatment equipment and appropriate materials. When the materials are stored in liquid state, the storage tank shall be sealed with inert gas (such as nitrogen) to prevent oxygen or air from entering. Long term exposure of materials to air or oxygen will lead to oxidative decomposition of materials. The stability of material color can be maintained by sealing with inert gas, and the dew point of dry inert gas used shall be less than - 40F.

ENGINEERING MEASURES:

Provide adequate ventilation, safety shower and eyewash equipment.

PERSONAL PROTECTIVE EQUIPMENT:

Respiratory:  Wear an air respirator when possible contact with steam and fog.

Eye :  Chemical safety glassed.

Clothing:  Wear appropriate protective clothing.

Hand:  Wear acid-resistant rubber gloves.
