1.1.1.1.2.17 Fire protection Reference: 1.1.1.1.2.34 Welding, 1.1.1.1.2.19 Foam and 1.1.1.1.2.25 Legal affairs. Many substances related to car maintenance are flammable substances. Some of them emit toxic or harmful gases after burning. Strict attention should be paid to fire safety when storing and using flammable substances or solvents, especially when welding or near electrical equipment. Before using welding equipment or heating equipment, make sure that there are no flammable materials around and place a fire extinguisher nearby. 1.1.1.1.2.18 First Aid In addition to meeting legal requirements, the repair shop must also be equipped with personnel trained in first aid.
Any substance splashed into the eYes must be rinsed with water for at least 10 minutes. After the skin is contaminated with chemicals, it should be washed with water and soap. After being burned by certain substances, immediately rinse with cold water to cool down. If smoke or dust is inhaled, immediately go to a place with fresh air. If it still does not work, please send to the hospital immediately. If you accidentally drink some liquids, please see a doctor immediately and tell the name and composition of the liquid. Unless specifically stated on the label, do not try to vomit. 1.1.1.1.2.19Foam-Polyurethane Reference: 1.1.1.1.2.17 Fire prevention. Foam is used to insulate sound and noise.
There is also foam in the seats and shock absorbers. Operate strictly according to the manufacturer's instructions. The unreacted ingredients are irritating and harmful to the skin and eYes. Please wear gloves and protective glasses. People with chronic respiratory diseases, asthma, bronchitis or allergies are not allowed to work on or near unvulcanized materials. Certain ingredients, vapors or sprays are irritating and may be toxic. Never breathe vapor and spray. These substances must be used in a well-ventilated area and measures to protect the respiratory system must be taken. After spraying, do not remove the mask immediately and wait until the mist is completely dispersed.
Burning uncured components and matured foam will produce toxic and harmful gases. Smoking, using open flames or power tools is strictly prohibited when handling foam. Any heating and cutting of the foam must be done in a place with air circulation. 1.1.1.1.2.20 Refrigerant Reference: 1.1.1.1.2.4 Air conditioning refrigerant. 1.1.1.1.2.21 Fuel (kerosene) Kerosene can also be used as heating fuel, solvent and cleaning agent. Kerosene is a flammable substance-the ban on smoking must be followed. Swallowing kerosene will irritate the mouth and throat. Long-term contact with such substances will make the skin dry and irritating, and it will be slightly irritating if splashed into the eYes.
Under normal circumstances, a small amount of volatilization will not produce harmful vapors. Avoid volatilization due to high temperature (acid mist will be generated during the dewaxing process). Try to avoid contact with skin and eYes and ensure good air circulation. 1.1.1.1.2.22 High-pressure gas cylinder Reference: 1.1.1.1.2.17 Fire prevention. High-pressure gas cylinders usually contain oxygen, acetylene, argon and propane at a pressure of 138 bar. Special care should be taken when handling such high-pressure gas cylinders to avoid mechanical damage to the high-pressure gas cylinder or the high-pressure gas cylinder switch device.
The gas in each high-pressure gas cylinder should be clearly 7
