Risk overview

Risk category:

Invasive approach:

Environmental hazards: on the environment can be dangerous, resulting in water contamination.

Flammable and explosive danger: it is inflammable, poisonous, irritating.

First aid measures

Skin contact: remove contaminated clothing, wash with plenty of water flow.

Eye contact: speaking of the eyelid, with the flowing water or saline rinse. Medical treatment.

Inhalation: from the scene quickly to fresh air. Keeping the respiratory tract unobstructed. If breathing is difficult, give oxygen. If not breathing, artificial respiration immediately. Medical treatment.

Ingestion: drink plenty of warm water, emetic. Medical treatment.

Fire fighting measures

Hazardous characteristics: itself does not burn. Heat released by the decomposition of toxic gases.

Hazardous combustion products: sulfur trioxide.

Fire extinguishing method: fire personnel must wear body fire suits, the wind direction on fire. When fire as far as possible the vessels to an open area. Then according to the selection of appropriate fire causes of fire extinguishing.

Emergent treatment of leakage

Emergency treatment: isolation of contaminated area, restricted access. Recommended emergency personnel wear anti-dust masks, wearing protective clothing. Do not directly contact with leakage. A small leak: avoid dust, carefully scan, collect and transport to the disposal of waste disposal sites. A large leak: collection of recycling or shipped to the disposal of waste disposal sites.

Handling and storage

Matters needing attention : closed operation, local exhaust ventilation. Prevention of dust in the air of workplace release to. The operator must go through specialized training, strict compliance with operating procedures. Recommended operating personnel wear self-absorption filter anti-dust masks, wearing protective chemical safety glasses, wear rubber acid and alkali resistant clothing, wearing rubber Naisuan Jian gloves. Avoid creating dust. Equipped with emergency treatment equipment for leakage. May be left empty containers of hazardous material.

Storage note: stored in a cool, ventilation of the treasury. Away from fire, heat source. To prevent direct sunlight. The packing must be sealed, keep away from moisture. With edible chemicals stored separately, avoid mixing reservoir. Storage areas should be equipped with appropriate materials asylum leakage.

Exposure controls / personal protection

Occupation exposure limit

Chinese MAC ( mg/m3 ): failure to develop standard

The former Soviet Union MAC ( mg/m3 ): failure to develop standard

TLVTN: is not set standards

TLVWN: is not set standards

Method: flame atomic absorption spectrometric method; catalytic polarographic method

Engineering controls : closed operation, local exhaust ventilation.

Respiratory protection: dust concentration in air exceed the standard, must wear self-absorption filter anti-dust masks. Emergency rescue or evacuation, they should wear air respirator.

Eye protection: wear protective chemical safety glasses.

Physical protection: wear rubber acid and alkali resistant clothing.

Hand protection: wear rubber Naisuan Jian gloves.

Other protective: workplace smoking, eating and drinking, to wash their hands before dinner. After work, a locker. To maintain good health habits.

Ecological information

Ecological toxicology toxicity:

Biological degradability:

Non biodegradable:

Biological enrichment or biological accumulation:

Other deleterious effects: migration: on land with the weathering into the soil, by some hydrolysate or oxidation sediments adsorption. Adsorption : some hydrolysis or oxidation of sediment adsorption; especially on colloidal soil two. Co has a very strong adsorption, in acidic soils, adsorption is not easy. Enrichment: in the natural environment, biological enrichment. The substances to the environment may be harmful, special attention should be paid to the pollution of water body.

Waste disposal

Waste properties:

Waste disposal method: safety burying method disposal. In the available local reuse of the container or provisions in place.

Waste matters needing attention:

Transport information

Dangerous goods code: no data

UN number: no data

Packing mark:

Packaging category:

Packing method: no data.

Transportation matters needing attention: departure to complete the packing, loading should be safe. Transportation process to ensure that the container does not leak, no collapse, not falling, no damage. With no food chemicals and other mixed mixed operation. Transit should prevent insolation, drench, anti high temperature. Transport vehicles should be thoroughly cleaned. Highway transportation according to the prescribed route.

Regulatory information

Regulatory information regulations on safety management of hazardous chemicals ( issued by the State Council on February 17, 1987 ), chemical dangerous goods safety management regulations implementing rules ( labour FA [1992] No. 677 ), the use of chemicals in workplace safety regulations ( [1996] labor department No. 423 ) regulations, the needle on the chemical dangerous goods safety, production, storage, transportation, loading and unloading are corresponding provisions.
