Protective Measures:

Engineering Control:Be airtight during the production process and enhance ventilation.

Respiratory Protection:No special protection is needed generally.It is recommended that a self-priming gas mask(half-mask)should be worn in special cases.

Eye Protection:No special protection is needed generally.Wear a pair of chemical safety goggles when contacting high-concentration triethyl orthoformate.

Body Protection:Wear antistatic overalls.

Hand Protection:Wear rubber oil-proof gloves.

Other Protection:It is forbidden to smoke,eat or drink at the work site.Take a shower and change clothes after work.Attention should be paid to personal hygiene.

 

First Aid Measures:

Skin Contact:Take off contaminated clothing and rinse skin thoroughly with soap and water.

Eye Contact:Lift the eyelid immediately and rinse with fluid water or saline solution for at least 15 minutes and then seek medical advice.

Inhalation:Withdraw from the scene to places with fresh air rapidly;in case of respiratory arrest,give artificial respiration;and in case of dyspnea,give oxygen.

Ingestion:Seek medical advice immediately.

Fire Fighting Methods and Extinguishing Agent:Foam,carbon dioxide,dry powder,1211 or sand.

Fire Fighting Precautions and Measures:When putting off a fire,stand windward and wear a gas mask or a self-contained breathing apparatus.

 

Emergent Leakage Processing:

Withdraw from the contaminated area to safe area and implement isolation and strict restrictions on access.Cut off source of ignition.Emergency processing personnel are suggested to wear self-contained positive pressure breathing apparatus and fire protective clothing.Don’t contact leakage directly.Try to cut off the source of leakage as far as possible and prevent the leakage from entering sewers,flood discharge trench and other restrictive space.

A Small Amount of Leakage:Adsorb or absorb with sand or other non-combustible material or rinse with plenty of water,dilute with water and discharge it into the wastewater system.

A Large Amount of Leakage:Build a causeway or trenching to take in and cover with foam to reduce the steam disasters.Transfer it to tankers or exclusive collectors with anti-explosion pump and then recycle or transport it to the waste disposal site.
