hould be directed towards the exhaust air outlet of a booth. Many chemicals used in spray painting or powder coating also have physicochemical hazards. Workers who are involved in spray painting or powder coating activities require relevant information, training, instruction or supervision to enable them to carry out their work safely. To keep apprised of such developments, you can consult OSHA's website at https://www.osha.gov. CONTROLLING THE RISKS OF POWDER COATING 2 4.1 Hazardous chemicals 28 4.2 Controlling exposure 29 4.3 Electrical safety 31 5. easy the object is to move and whether work systems and plant could be improved.

Special first aid requirements apply, chromic acid, chromate or dichromate solutions (may cause cancer, burns and skin sensation), and. CONTROLLING THE RISKS OF POWDER COATING........................................... 4.1     Hazardous chemicals........................................................................................................... 4.2     Controlling exposure............................................................................................................ 4.3     Electrical safety.................................................................................................................... 5. implementing good personal hygiene practices, for example powder coating dust should not be allowed to collect on the face, exposed body areas should be thoroughly washed and overalls should be regularly cleaned, storing powder coating and waste powder in a designated area with restricted access, cleaning booths and surrounding areas on a regular basis, promptly cleaning-up spills of powder coatings to reduce the spread of TGIC, using a vacuum cleaner with a High Efficiency Particulate Air (HEPA) filter for clean-up operations and not using compressed-air or dry sweeping, vacuuming work clothing as an initial method of decontamination, emptying vacuum cleaners in the booth and under exhaust ventilation, taking care to avoid the generation of dust during disposal of waste powder, baking waste powder in the original box for disposal to landfill as a solid, ensuring all electrical equipment is switched off before cleaning spray guns. (d) Dilution of Flammable Vapors. 1.1       What are spray painting and powder coating? Higher protection factors, for example full face or powered air purifying respirators, will be required where ventilation is not adequate. At least 2 metres extending in all directions from any opening or outlet. Inside exhaust ventilated enclosed area. At least 5 minutes after spraying with booth operating. Further, isocyanate-containing materials may release isocyanates into the atmosphere when heated. - Administrative and PPE controls should be used for touch up. Question 3: Could one use a small portable spraying apparatus with flammable paint to paint a fender or door of a truck inside an automotive maintenance garage? Information on methods of bonding, dissipating charge from installations, and electrical isolation to prevent static discharge can be found in, touching two metal cans together during decanting, clothing or synthetic fibres prone to accumulation of static charge including nylon, pure wool, wool blends (unless treated) and non-conducting footwear, airless spray painting using high fluid pressure (control this by electrically earthing the airless spray gun and any conductive article that is being sprayed including a container. We recommend that any outside spraying operation be located in the downstream air from the employee. , heat stress, visibility, noise from plant and injection injury. The hazard control factors of distance and time referred to in this appendix are provided as a guide and are based on AS/NZS 4114.1 and AS/NZS 60079.10.1. 33-1989 does not address outside spray painting operations. Example of an exclusion zone when conducting outdoor spray painting. 1917.153 (c) (1) Shut-off valves, containers or piping with attached hoses or flexible connections shall have shut-off valves closed at the connection when not in use. I am satisfied that this code of practice was developed by a process described in section 274(2) of the. Are the control measures working effectively in both their design and operation? Are workers actively involved in identifying hazards and possible control measures? Reply: It is permissible to use a small portable spraying apparatus providing the requirements of the latest applicable consensus standard, NFPA No. Spray painting equipment including pumps and compressors, can generate varying levels and frequencies of noise that may cause workers to be exposed to noise that exceeds the exposure standard. At least 5 minutes after spraying with spray booth operating. substituting a noisy process or machine, such as an air compressor or extraction fan, isolating the source of noise from people by using sound proof enclosures or barriers, using engineering controls, for example sound absorbing materials, mufflers, using administrative controls, for example limit the amount of time people work in noisy areas, and. In general, the exclusion zone should, as far as is reasonably practicable, have at least six metres horizontal and two metres vertical clearance above and below the place where the paint is being applied. The register must list all the hazardous chemicals at your workplace and their current SDS, for example for any paints, coatings, solvents and thinners, fillers, strippers and cleaning products that are hazardous. burns – flashes and arcing due to short-circuiting may lead to severe tissue burns or the ignition of flammable gases. proper induction training and general training of workers. What is required to manage risks associated with spray painting and powder coating? 33-1989 is acceptable so long as equal or greater protection is provided. Workers must comply with any reasonable instruction and cooperate with any reasonable policy or procedure relating to health and safety at the workplace. Spray painting requirements for door and outdoor spraying areas and booths. Where there is no exposure standard, exposures should be kept as low as reasonably achievable. Until concentration of volatile components has dropped below exposure standard. However, any type of footwear can, Powder paints used in powder coating processes are usually combustible and the accumulation, A person conducting a business or undertaking must ensure that flammable, open flames including matches, lighters, cigarettes, cutting torches and welding, hot surfaces including engines, motors and light bulbs, chemical reactions, mixing hazardous chemicals can generate heat or static and create an ignition source, sparks from electric equipment, portable electric tools, power points, radios, mobile phones, catalytic reactions, for example a catalyst speeds the resin hardening process when two-pack epoxy paints are mixed and this creates heat, and, before pouring flammable liquids from one container into another, set both containers down, where containers have air lines, always replace the plugs as soon as the air lines are disconnected, provide suitable fire extinguishers that are readily available, store and handle flammable or combustible liquids safely, for example, always return unused liquid to a labelled container for that liquid, store solvents in covered containers with taps to avoid the need for pouring, solvent soaked rags should be stored wet and safely contained after use or removed from the workshop, store flammable chemicals, mixtures or materials including unused liquid in tightly closed containers that are correctly labelled, store flammable chemicals, mixtures or materials in well ventilated storage areas, replace lids of containers after each use, do not leave containers of flammable liquid near any heat source or source of ignition or in direct sunlight, and. This standard applies to all spraying areas and does not categorize the application equipment with respect to size. full length overalls with hood, appropriate chemically resistant gloves and eye protection (appropriate for mists/vapours). (2) No means of heating make-up air shall be located in a spray booth. performing work at height in a manner that allows workers to form a comfortable position, reducing the amount of force necessary to perform tasks, for example by using rigging. Health monitoring by doctor to be provided for all workers who previously worked with insufficient controls (half-face respirator and latex gloves) and to painters on an ongoing basis due to the high hazard of the isocyanates in paint.
