TO 35-1-3 2.2.6.2 Training Requirements. There are several types of training that can be used to properly train personnel in the proper use and safe operations of the HPW equipment and processes. Regardless of the training method, all personnel shall be properly trained prior to operating equipment. 2.2.6.2.1 Manufacturer Provided Training. The equipment manufacturer may provide on-site, video, or computerbased training for the safe operations of the equipment. 2.2.6.2.2 Locally Developed Training. A locally developed training program can be used for general instruction of equipment operation and safety requirements. This training should include hands-on practical training in HPW paint removal using all appropriate safety equipment. a. The HPW equipment should have the operating parameters of water pressure not to exceed 40,000 PSI; water flow of 2.85 GPM, bicarbonate of soda blast media flow rate 1/4 to 1/2 lb. per minute. b. The nozzle standoff distance should be within the range of 2 to 4 inches from the tip of the nozzle to the working surface. c. The angle if incidence between the nozzle and the work surface should be within the range of 40 to 60 degrees from the surface being stripped. d. The nozzle should be moved across the surface at a minimum rate of 4 inches every second. • High Pressure water can cause serious personal injury if the nozzles are directed at personnel. Never point the nozzle in the direction of other personnel. • Water and blast media can create slippery conditions. Walking on top of equipment should be avoided. Use fall protection and all work stands shall have guardrails in place. 2.2.6.3 Personnel and Equipment Preparation Prior to HPW. Prior to performing the HPW paint removal process, the following measures should be taken to ensure the safety of personnel and protection of the equipment to be depainted. a. Defuel and disconnect the battery of the equipment to be depainted. b. Ensure the SE seams, and crevices are protected from water intrusion/entrapment to prevent corrosion. c. Remove and protect from the high-pressure water steam, all soft metal/non-metal components such as data plates, copper parts, hoses, etc. d. All sources of ignition shall be kept a minimum of 50 feet way from the HPW paint removal process. e. Personnel involved in the HPW process shall wear as a minimum earplugs, earmuffs, full-face shield, wetweather gear, water-resistant hood, waterproof shoes, and shin and instep guard assemblies. The skin and instep assembly should be puncture resistant aluminum with a 5-inch wide by 6-inch long instep section attached by a hinge assembly to a shin section of at least 20-inches length. 2.2.6.4 HPW Paint Removal Operation. Care should be taken in HPW paint removal operations to preclude blasting media intrusion and warpage of unsupported thin panels. 2.2.6.5 Post HPW Paint Removal Cleaning. After completing the HPW paint removal process the following steps should be taken to ensure equipment is protected again flash rust and corrosion: a. Remove any protective materials. b. Areas where the coating was shielded from the HPW process should have paint mechanically or chemically removed per TO 1-1-8. c. Open, inspect, and flush all areas where blast media may be entrapped with clean, fresh water. d. The equipment or components should be thoroughly washed in accordance with Chapter 2 of this technical order. e. Allow the equipment and/or components to thoroughly dry. f. Prepare equipment and/or components for a coating system or treat with a Flash Rust Inhibitor such as Hold- Tight 102. Flash Rust inhibitors are temporary rust inhibitors that usually allow an additional 48-hour interval before priming without flash occurring. NOTE HPW Paint Removal will present a high potential for flash rusting on equipment. Ensure equipment is primed or treated with a Flash Rust Inhibitor within a maximum of 48 hours after paint removal. HPW Paint removal operations can damage equipment and personnel if instructions and precautions are not followed. Following the requirements below are necessary to prevent damage: Change 4 2-19/(2-20 blank)
