precautions when purchasing paint

the most effective way to prevent paint poisoning is to maintain good ventilation conditions at the painting site to reduce the concentration of toxic and harmful substances in the air. If the ventilation conditions at the painting site are not good, you should rest in the ventilation place for an irregular time after painting for a period of time. In addition, you should try to avoid contact with skin and solvent based paint. Therefore, necessary labor protection measures should be taken during coating, such as wearing tight ear work clothes, gloves, masks and protective glasses. Avoid direct contact with the skin and harmful gases entering the respiratory system. After painting, the tools and residual materials shall be cleaned in time, and the paint barrel shall be closed. The solvent barrel shall be covered, and the silk return and waste cloth head of the paint shall be disposed of in time. Avoid washing hands with toxic solvents (such as solvents with high benzene content), do not eat at the construction site, wash hands and face with soap before meals or after work, and change work clothes
