     In a painted environment, work 8 hours a day, although working in a safe environment, but everyone's sensitivity, tolerance is not exactly the same. The longer the time, accumulated over time, it is inevitable that the body is not affected by painting, paint contains a variety of solvents containing benzene and benzene compounds, such as toluene, xylene and so on. Thinners in ethanol, butanol and other commonly used industrial solvents are also toxic, and even some have highly toxic, such as methanol and other
    in
    . The presence of these toxic substances, the human nervous system, respiratory system and skin, such as a certain degree of toxicity, the most common phenomenon such as benzene poisoning and paint poisoning.
    in the car coating process, often produce a large number of volatile gases, diffused in the air. These large amounts of toxic hot gas, if inhaled by the human body, will occur neurological diseases, generally appear dizziness, palpitations and nausea and vomiting and other reactions. Fingers and other parts of frequent contact with a variety of solvents and toxic gases, but also can cause skin corrosion, skimming, itching, rough, cracking and other diseases. Therefore, in the automobile coating work place, we must take the necessary protective measures, from the following aspects of consideration: 1, establish the safety first thought, enhance the concept of protection
    First of all, we should understand the type and characteristics of paint, toxic damage to the human body, paint use precautions, as well as the possible occurrence of poisoning first aid measures. Especially in indoor, cabin, underground construction site, mine, vehicle and other poorly ventilated or no ventilation of the environment, never allowed to exceed the maximum allowable concentration of solvents and working time limits.
    construction personnel must know the packaging signs of toxic solvents in front of time, and master the safe use of solvents. In particular, the person in charge of construction and the relevant personnel responsible for safety must establish a clear post responsibility system, supervision and inspection of the implementation of safe production and labor protection regulations and related operating procedures. The construction method, the distribution and use of labor protection supplies, the normal operation of exhaust and air-breathing equipment to carry out the necessary supervision, and often to the construction personnel safety education, firmly establish the idea of safety first and labor protection concept, timely eliminate all kinds of unsafe hidden dangers, to ensure safe production.2. To ensure the normal operation of construction equipment and safety protection devices
    In the process of automobile coating construction, the correct construction process, normal and perfect construction equipment and safety protection devices are the fundamental guarantee of safe production, which is indispensable and a complete system engineering.
    in the rapid development of science and technology today, in everyone attaches importance to the safety of production of modern, general coating production site, the conditions are still relatively good. But in some maintenance enterprises, some township enterprises in poor condition, often appear in one way or another, this is a weak link, should be paid attention to. Unsafe hazards should be eliminated from the process, from construction equipment and safety protection devices. Depending on the specific conditions of the coating production, consider the configuration and use of the coating construction equipment and safety protection devices used. For example, volatile solvents used in indoor construction should be used to contain equipment or install exhaust devices to prevent leakage of equipment. If applied inside tanks and tanks, it is important to ensure that the exhaust and intake amounts are balanced. In short, the necessary construction equipment and safety protection devices should be necessary to ensure the safety of coating production.3. Improving the construction environment and ensuring normal ventilation
    is very important for spray construction sites, normal ventilation and ventilation, is the fundamental measure to prevent fire and explosion accidents, and is also an important means to prevent harmful gases exceeding the standard. In general, the window and other opening parts directly with the outside air part of the area, should be painted workshop floor area of more than 1/20, in order to be able to carry out normal breathing. If there is good performance ventilation equipment, can not be limited by the above ratio. In the actual situation of coating production, the amount and type of paint use are constantly changing, the production and discharge of volatile gases are not balanced, are with time, region, spraying conditions and no certain laws change. To this end, we should often carry out the necessary testing, strictly control the "three waste" exceeding the standard, find problems, timely solution, must not have a once and for all thought.4. Fire safety
    painting of
    automotive paint
    is a construction method that uses compressed air flow to spray paint out of the spray gun and is foggy, dispersing and depositing on the surface of a processed object. This method can not ignore fire prevention, generally should pay attention to the following problems:
    1, paint workshop should generally be set up separately, and install ventilation equipment, rapid exhaust.
    2, the workshop should be responsible for fire prevention, fire prevention system and fire extinguishing equipment.
    3, fireworks and all open flames are strictly prohibited in the workshop.
    4, the workshop should take measures to prevent sparks. Electrical equipment should meet the requirements of explosion-proof, exhaust fan imperms should be made of non-ferrous metals, and prevent friction impact, should control the speed of painting, prevent static electricity, all equipment should be grounded.
    5, should do a good job of equipment maintenance, often remove paint deposits in the workshop and exhaust pipes.
    6, strictly control the store of paint and solvents in the workshop. In addition to ensuring the use of the same day, should not be stored too much, even if there is a small amount of use of the remaining paint and solvents, should be properly stored, the cover will be covered to reduce volatility.
    7, pay attention to the fire hazard of the paint room., strengthen the construction environment testing to strictly prevent the "three waste" over-standard
    indoor construction, at least semi-annual inspection of air concentration, in order to maintain a good construction environment. This is in the car coating production is relatively normal and no difference in the case of the proposed. For large changes in coating production, such as production, process has a larger change, it is necessary to the important parts, that is, the unsafe factors of the larger parts, timely detection. Keep track of the changing state of the data in each part in order to take appropriate measures. For widely used organic mixed solvents, such as acetone, xylene, toluene, ethanol acetate, DCH, etc. must be regularly checked for contamination, to determine the sampling site. Mainly selected in the exhaust inside, exhaust port, floor, ceiling near and other parts, and determine the concentration distribution, and select the same plane interval site as the measuring point. According to the measured data and distribution status, check with the control standard. If there is a exceeding standard, appropriate measures should be taken to deal with, to prevent the occurrence of accidents, to ensure that the construction has a good and safe environment.6, the protection of operators
    in the car coating process, operators in the construction site, directly in the paint and solvents in the site of operation, a variety of toxic gases and solvents perforated, flooding the entire site. Therefore, it is very necessary and necessary to protect the operator personally. This is also an important part of coating safety technology.
    construction personnel should wear a variety of protective equipment, such as work clothes, gloves, masks, masks, glasses and shoes and hats. Do not allow solvents to touch the skin. Also rub exposed skin on medical Vraslin or other skin care products. The boiling point of solvent is low, volatile fast, toxic, easy to inhale tracheal spraying site to pay special attention to strictly prevent inhalation of the lungs.
    toxic gases emitted during the construction of the plant, at high concentrations, have a serious stimulating and harmful effect on the nerves of the human body, which can cause cramps, dizziness, coma, pupil enlarge and other symptoms. At low concentrations, headaches, nausea, fatigue and abdominal pain also occur. If not protected in time, in long-term contact can reduce appetite, damage the blood system, the occurrence of chronic poisoning.
    paint mist can not only be inhaled through the lungs, but also through the skin and stomach absorption and harmful effects. Long-term contact with paint on the human surface, can dissolve the skin surface fat, resulting in dry skin, cracking, redness and may cause skin diseases.
    paint pigments contain toxic ingredients, such as red dan, lead chromium yellow, etc. , this coating should be painted, it is best not to spray. When used, precautions should be taken, this coating can cause acute or chronic lead poisoning, it is best to choose other coatings to replace, reduce the possibility of poisoning.
    the spray-on spray, do not immediately stop the ventilation and ventilation equipment, let the operation continue for a period of time, the residual paint mist and solvent volatile gas discharge.
    spray paint, if the operator feels the tracheal dry knot, it is due to inhalation of the solvent evaporation in the paint mist, should drink more warm boiled water. When clearly spraying guns and tools, try not to touch the skin with solvents. When finished, wipe off Vashlin or other skin care products on your skin and wash your face with warm water and soap, preferably in the shower.
    shall conduct regular physical examinations on the coating operators, and give timely medical treatment to those who have been poisoned.
