During transport should be prevented from direct sunlight, rain, packaging damaged. Should be stored in a cool, ventilated and dry place, away from fire, heat source to prevent direct sunlight, damp. Treasury temperature should not exceed 32 ℃, relative humidity of not more than 80%. Sealed packaging. With oxides, alkali, and other combustible items are kept separately. Summer under high temperatures were not long-term storage.
Security matters:
Chloroacetic acid for the acidic corrosive substances, there is irritating smell. Eye, mucous membrane, skin burns and so there is dangerous. And human contact is strictly prohibited. Such as skin contact, immediately wash with water. If it burns, medical treatment; such as misuse of contact with eyes, immediately filed eyelid, mobile water or normal saline flush at least 15 minutes; such as misuse of inhaled quickly from the scene to fresh air, the necessary artificial respiration, seek medical treatment. The operator should wear protective glasses, rubber gloves, rubber boots and other labor protection supplies.
Combustible in case of meeting fire or high fever. Heat generated by the decomposition of toxic corrosive flue gas. With strong oxidizer chemical reactions can occur. Chao met when there is strong for most metal corrosion.
Ask MSDS when needed.
