.. 14� 3.4.2 Pressure Washing Hazards Only trained workers will be allowed to operate the pressure washing equipment. The equipment must be inspected prior to use to ensure it is operating conditions, in particular a spring-released trigger should be present and working and the hoses should be in good condition. The lowest pressure that is effective to do the job should be used. Workers operating the equipment and those within the exclusion zone must be aware of the potential for splash from the heated water and flying objects from the washed area. Workers must use a face shield with side protection and water-proof coveralls(polycoated tyvek or rain gear that can be decontaminated). The pressure wand should never be pointed at another person. Loose or frayed clothing, rins, chains,or other dangling clothing should not be worn. If there is a sudden or slowing stopping of the water flowing through the wand, the machine should be shut off immediately before other damage may occur. All workers should have non-slip footwear that is in good condition that will also solid footing on slippy surfaces that may be created during the pressure washing. 3.4.3 Weather Hazards (Heat, Cold, Rain, Fog, Lighting, Sparks) It is anticipated that this work will be done during the fall and winter months. Work may continue in light rains and wind,but must be suspended when be suspended if the rains are heavy or wind speeds are above 20 mph. Work shall not be done if there is any potential for an electrical storm to occur. Additional, if fog interferes with workers ability to remain in visual contact,work must be suspended. In addition, workers should be aware that when humidities are very low (e.g., <20%) there is an increase chance of having sparks caused by friction. During the fall and winter, workers must be prepared for working in cold temperatures. Workers should take steps to prevent cold stress and be aware of the symptoms of cold stress. Preventative steps include: ♦ Dressing warmly: -dress, in layers with materials that insulate but also allow sweat to evaporate(e.g., cotton and wool), clothing should include items which protect the feet, hands,head, and face. However,hoods, loose fitting clothing, dangling belts and jewlery should not be worn due to the other threat of catching in moving machine parts. ♦ Keep dry: wetness greatly increases the chance of cold stress, have extra clothing available if there's a chance you could get wet. ♦ Take a break: become fatigued during physical activity reduces the body's ability to properly retain heat.
