Set up decontamination area upwind of the drilling site. This means get water and <br /> cleaning solution in your buckets to wash off your boots and gloves prior to beginning <br /> work. You want to set up the decontamination area at a sufficient distance from the <br /> excavation or boring work to be reasonably sure you are not in an area that can become <br /> contaminated by splashing water or flying dirt. Your support area is where you park the <br /> truck, etc. It is the place you need to consider as clean. You do not want to make it <br /> "dirty" by any of your activities. It is anticipated that work will start in Level D, but be <br /> prepared to up-grade or leave the site. <br /> Inspect exclusion zone (the area where you are going to excavate, where you suspect <br /> contamination, either "on-site" or off) for spark sources, paying careful attention to <br /> electrical equipment. Do not start excavation or boring work until all possible sources of <br /> ignition have been removed. Secure the area to prevent the public from approaching <br /> within 25 feet of any sampling, digging, or drilling. <br /> i Work Limitation: <br /> - No eating, drinking, or smoking within 50 feet. <br /> - No facial hair that would interfere with respirator fit. <br /> - Level C is not to be used without two fully trained staff on- <br /> site. If monitoring results indicate than an up-grade is <br /> �✓ required, you must leave the site until conditions change or <br /> request an additional person, and not initiate work until that <br /> person arrives. <br /> - Stress breaks are to <br /> be taken at regular intervals of 2 hours, <br />{ or more frequently, if necessary. <br /> - No sparks sources within 50 feet of the work area. <br /> - All open excavations shaII be adequately fenced <br /> All open excavations shall be shored or sloped, where <br /> applicable, to prevent accidental collapse. <br /> - All employees involved with hazardous waste activity shall <br /> meet health and safety training requirements. <br /> 1 Decontamination Procedures: <br /> For sampling or sub-surface disturbance activities for personnel: Wash boots and outer <br /> gloves in cleaning solution and water, rinse, remove outer gloves.
