I. Ventilation Requirements
Work must be carried out in an open, well-ventilated outdoor area or a workspace with forced exhaust ventilation. Work in enclosed/semi-enclosed rooms is strictly prohibited. Regularly monitor the concentration of flammable gases inside and around the container to ensure it does not exceed 25% of the lower explosive limit, preventing the accumulation of flammable and explosive paint solvents that could lead to an explosion. Cleaning operations are prohibited on days with low air pressure or winds exceeding level 5, to avoid hindering the dispersion of harmful gases and creating safety hazards.
II. Personal Protective Equipment
Wear corrosion-resistant rubber gloves, goggles, and a mask with an organic vapor filter at all times. Avoid direct contact between hands and corrosive cleaning agents or paint residue to prevent inhalation of harmful gases and to protect eyes from splashing paint splatter and cleaning agents.
III. Work Safety Management
The work area must be kept away from heat sources, open flames, and high-temperature objects. Hot work operations are strictly prohibited in parallel. Use explosion-proof tools that do not produce sparks. Take anti-static measures to prevent sparks from friction and impact that could cause an explosion. The total amount of flammable organic solvents used by each person per cleaning operation should not exceed 4L to reduce safety risks.
IV. Compliant Disposal of Waste Liquids and Materials
Waste liquids containing paint, waste cotton yarn, rags, and other materials generated during cleaning must be collected in sealed containers and handed over to a professional unit with hazardous waste management qualifications for disposal. Random dumping or mixing with domestic waste is strictly prohibited to avoid environmental pollution and secondary safety hazards.
