1.1.1.1.2.5 Sealants and adhesives Reference: 1.1.1.1.2.10 Chemicals. Flammable substances - no smoking must be observed. In general, sealants and adhesives should be stored in non-smoking areas, and must be kept clean and tidy. For example, they should be placed on the shelf covered with disposable paper towel, and it is better to take them out of the packaging box and place them separately; the packaging boxes, including the sub packaging boxes, should be labeled accordingly. (1) Solvent sealants and adhesives The manufacturer's instructions must be followed.
(2) Water soluble sealants and adhesives This kind of water-soluble viscose based on polymer emulsion and rubber latex may contain a small amount of volatile toxic substances and harmful chemicals to human beings. Avoid contact with eYes and skin and good ventilation should be ensured when using. (3) Hot melt adhesive The solid state of such substances is safe. In the molten state, they can cause combustion and release toxic gases, endangering human health. During operation, correct protective work clothes must be worn, constant temperature heater with automatic power-off function shall be used, and sufficient ventilation equipment shall be provided.
(4) Resin based sealants and adhesives such as epoxide and resin formaldehyde The adhesive must be mixed in a well ventilated place, because the mixing will release harmful or toxic volatile substances. Skin contact with wet resins and hardeners can cause dermatitis, and some toxic and harmful chemicals can be absorbed by the skin. If spilled material enters the eye, it will cause eye damage. Therefore, keep good ventilation and avoid contact with skin and eYes during operation. (5) Anaerobic cyanoacrylate binder and acrylic adhesive Most of these adhesives are irritant, allergic or harmful to skin and respiratory tract. Some of them are highly irritating to the eYes.
Avoid contact with skin and eYes and follow manufacturer's instructions when working. Do not allow cyanoacrylate adhesive to contact skin and eYes. If it is accidentally touched, please put on a clean wet cloth or consult a doctor immediately. Do not touch the injured part with hands. Choose a well ventilated place because water vapor can irritate the eYes and nose. (6) Isocyanate (polyurethane) sealants and adhesives Reference: resin adhesive. No one with asthma or other respiratory diseases should be exposed to or close to these substances. Excessive exposure to these substances can irritate the eYes and respiratory system.
High concentrations can stimulate the nervous system and, in severe cases, cause unconsciousness. Prolonged exposure to these substances can have an impact on health. Long time contact with the skin will stimulate the skin, and in severe cases, dermatitis will occur. If it enters the eYes carelessly, it will damage the eYes. Any spraying action must be carried out in a well ventilated place and keep the steam and sprayed particles away from the breathing area. Proper gloves, glasses and masks must be worn during operation. 1.1.1.1.2.6 Antifreeze Reference: flammable substances, 1.1.1.1.2.31 Solvents. Antifreeze includes: isopropanol, glycol, methanol.
Highly flammable, flammable and combustible. Used in automobile cooling system, wiper spray water solution. When the antifreeze is heated, it will produce vapor. Avoid inhaling such gases. Antifreeze or other harmful substances may enter the body through the skin. If you drink antifreeze accidentally, it may be fatal. You must seek medical advice in time. The use of such substances in any cooling or industrial water system associated with food processing or drinking water systems is prohibited. 4
