Administrative data

First-aid measures

Inhalation: Wash nose and throat thoroughly with gargle. Move into fresh air and keep at rest. According to symptoms, get medical attention if necessary.

Skin contact: Remove/Take off contaminated clothing and shoes. And rinse immediately with plenty of water and soap. Seek medical advice as soon as possible. Accordance with treatment of general burn and get immediate medical advice/attention, because may cause severe chemical burn as powder.

Eye contact: Immediately flush carefully with clean water for at least 15 minutes. Be necessary attention consult an ophthalmologist. In case of eye wash, rinse water into every corner with the eyeball and eyelids as eyelids often by finger.

Ingestion: Do not induce vomiting unless. Wash mouth well, immediately get medical advice/attention.

Fire-fighting measures

Suitable extinguishing media: Water spray, foam, dry chemical, inert gas.

Unsuitable extinguishing media: No data available.

Special fire fighting procedures: Evacuate non essential personnel from surrounding of the fire occurs place. Use appropriate extinguishing media for surrounding fire, and eliminate sources of ignition in the origin of fire.

Accidental release measures

Personal precautions (protective equipment and emergency measures): Wear suitable protective equipment during handling.

Environmental precautions: Do not release to the environment: Strong irritating, Take appropriate measures of report to the local residents at cause to leakage.

Methods and materials for containment and cleaning up: Evacuate non essential personnel and keep away from sources of ignition in the origin of fire. Collect into tightly closed container with process for prevent splashing dust of absorb by vacuum. Wear suitable protective equipment during handling. Prevent inhalation of vapor or skin contact.

Handling and storage

Technical measures (total or local exhaust ventilation): Take equipment measures and wear suitable protective equipment. Use local exhaust ventilation.

Precautions for safe handling: Irritating odor may cause severe chemical burn by contact with skin. Necessarily wear protective equipment.

Storage: Appropriate storage conditions: Keep in a tightly closed container; keep it room temperature or less. Take certain to temperature management. Take certain to damage of packaging materials, and wet in the water.

Exposure controls / personal protection

Administrative level: Use tightly sealed apparatus, equipment or local exhaust ventilation as possible. Also install safety shower, hand wash and eye wash equipment close to handling area and indicate their position clearly.

Personal protection equipments Respiratory protection: Wear necessarily dust mask, and use self-contained breathing apparatus (SCBA), hose mask, airline respirator, and gas mask for organic gas when high concentration processing.

Hand protection: It is effective to hand with barrier cream, when cause the skin contact.

Eye protection: Wear safety goggles for the non-contact with eye.

Skin and body protection: Use rubber protective clothes and rubber boots, if there is the case of skin contact. When there is remove protective clothes, cleaning protective clothes by air, in place installed of local exhaust ventilation.

Stability and reactivity

Chemical stability: Stable under normal conditions. If the substance is stored under high temperatures for a long time, it solidifies and reacts with oxygen in the air to cause self-heating resulting in its carbonization.

Possibility of hazardous reaction, conditions to avoid, incompatible materials and hazardous ecomposition products: No data available

Disposal considerations

Residual waste: Dispose of contents in accordance with local/regional/national/international regulations. Dispose of wastes with small amounts in incinerator. If disposal of the containers are impossible due to no treatment facility or the other reasons, dispose of by commissioning a licensed agency for industrial waste disposal.

Contaminated containers and packaging: Dispose of container in accordance with local/regional/national/international regulations.
