Note: Contaminants are anticipated in some, if not most, areas of subsurface work; should evidence of contamination become apparent, then protective gloves, including a latex liner and chemical resistant outer gloves and Tyvek-coverall will be required(see selection criteria below). In addition, latex over- boots(disposable)or reusable chemically resistant over-boots or steel toe over the sock rubber boots will be necessary. Provisions for decontamination must be established at any exclusion zone where non- disposable outer boots are to be wom. Connection between outer boots and suit, outer gloves and suit must be sealed with duct tape whenever polyethylene or saranex-coded coveralls are in use. For operations which require work gloves to protect the hands from abrasion, sharp edges, etc., leather(or equivalent) work gloves may be worn OVER chemical resistant gloves. Such gloves will be dedicated to exclusion zone work, but must be assumed i to be chemically contaminated once put into service. ' Upgrades of additional equipment may be mandated by the FSS based upon conditions or activities. Substitutions other than those described in this section are permissible only upon approval by the FSS. i' 8.2 Level C Protection Consists of the addition of the following respiratory protection to the Level D ensemble (Section 8.1): • Full face air purifying respirators with combination HEPA/organic vapor/acid cartridges. ' Eyeglass inserts MUST be provided for those employees who require prescription eyewear. 8.3 Criteria for upgrading to level C ' The presence of any one of the following conditions shall be sufficient to require Level C PPE. ' Verified detection of combustible gas levels in the breathing zone using the combustible gas meter. The detection of methane is likely to be an indication of the presence of other contaminants. • "Verified" organic vapor levels in the breathing zone, as measured by PID: ' > 2 ppm above background, sustained for five minutes. 215 ppm above background, sustained for one minute. • The detection of readings above background at the borehole/pit shall be noted in the sampling log as evidence of environmental contamination, but only ' CRC Environmental Misr Management,Inc.
