Topic 8 Coating industries  1. Safety, environment protection Contents and health 2. Industrial standards & specifications Safety, environment protection and health When working with any coating or coating material, it is essential that workers strictly follow manufacturer’s guidelines for the success of the process and the safety of workers. Every manufacturer publishes specific and concise directions regarding the safe handling of coating materials Applications Building materials including decking systems, engineering roofing, and architectural products Consumer packaged goods including plastics, commercial containers, and canning Walking surfaces and industrial machinery Reactors Columns Agitators Valves Vessels Pressure filters Piping Baffles Level gauges Wheels/rims Iron fencing Automotive frame Patio furniture Hazard The presence of flammable or toxic preservative coatings creates serious hazards during hot work. A toxic substance is defined as any chemical substance that has yielded evidence of an acute or chronic health hazard or is the subject of a safety data sheet indicating that the material may pose a risk to human health The hazards include: Fire Explosion Inhalation hazards - including gases, vapors, and aerosols Coating technology potential risk 1. Electroplating – can potentially have asphyxiants such as hydrogen in the workers' breathing zone. 2. Anodization – Spilling can cause contact with skin and eyes 3. Hot-dipping - poses risks to worker safety because involve molten solutions, which. Exposure to fumes from zinc oxide or magnesium oxide can cause metal fume fever/’zinc shakes” 4. Thermal spraying - bright UV light can burn skin or eyes, and the intense heat can pose a fire or explosion hazard. 5. Chemical conversion - Known or suspected carcinogen for humans. hazardous when inhaled and/or touched that may cause skin and eye irritation. Sources of hazards in coating 1. Hazardous Material Handling 2. Hand and Power Tools 3. Abrasive Blast-Cleaning Equipment 4. Spray Equipment 5. Welding and Cutting of Coated Steel Most common health and safety concerns of traditional coatings 1. Volatile Organic Compounds and Hazardous Air Pollutants 2. Flame Resistance 3. Microbes, Bacteria, and Other Germs Volatile Organic Compounds and Hazardous Air Pollutants VOC is an organic chemical compounds which contain carbon, including methylene chloride, benzene, and formaldehyde. VOCs are found in vehicle emissions, man-made consumer products, and, notably, anti- corrosion coatings and paints. Their high vapor pressure allows molecules to evaporate into the surrounding air, causing humans near breathe them in as vapors or gases. Hazardous air pollutants (HAPs)—which are suspected to cause cancer and other serious health problems—are released into the atmosphere at the rate of millions of pounds per year Compounds including benzene, chlorobenzene, ethylbenzene, acetone, chloroethane, styrene, vinyl chloride, toluene, and xylene are among the common HAPs found in traditional paints and coatings. Flame Resistance Many traditional anti-corrosion paints use organic compounds that fuel a fire in the workplace. These compounds are far more likely to ignite or melt than inorganic compounds, contributing to the growth of a fire, so they cannot offer flame- spread protection on their own Microbes, Bacteria, and Other Germs The danger of microbes lurks on surfaces and substrates, particularly where moisture is present. for instance, the environments of an offshore oil rig, livestock feeding areas, railroad cars, or freighters and cargo ships. These largely steel structures are breeding grounds for bacteria, viruses, protozoa, and fungi, which can cause everything from allergic reactions to serious health problems for those who work in proximity to them.  1.

Industrial standards & specifications INDUSTRIAL COATING Industrial standards & specifications The coating specification will determine the entire scope of any coating project. Example: for a steel structure painting project, specifications need to be developed for the following areas: the product to be used, the surface preparation required, and the application of the product. ASTM's paint and related coating standards are instrumental in specifying and evaluating the physical and chemical properties of various paints and coatings that are applied to certain bulk materials to improve their surface properties.  List coating standards in oil Discuss and gas industry and give List coating feedback standards in aerospace in the ecampus List coating standards in automotive
