Based on the preliminary site information including evaluation of the hazards at the site and Partner's experience, <br />personal protective equipment (PPE) will be required for all personnel and visitors entering the controlled portion <br />of the site. PPE for each potential level of protection is described below. Both Level C and D PPE should be <br />available on-site during all phases of the project, as conditions may change and require additional PPE. Work <br />should be conducted in Level D and no breathing protection will be required as long as monitored breathing zone <br />vapor concentrations remain in the nominal operation action level. <br />If on-site personnel find that breathing zone concentrations remain above nominal operation action level for more <br />than 5 minutes, then the SSO or PM will make a determination if breathing protection is needed. At this time, all <br />work in the affected area should be suspended until a decision is made. Implementation of Level C PPE will be <br />required if work continues during elevated breathing zone concentrations. Donning and use of respirators shall be <br />performed in accordance with manufacturer specifications. Replacement of respirator cartridges shall be performed <br />in accordance with manufacturer specifications. All respirators and cartridges shall be stored in air tight bags while <br />not in use. <br />Please refer to the PPE Levels of Protection for a detailed description of the equipment associated for each level of <br />PPE. <br />PPE Levels of Protection <br />Level D (to be used at all times) is as follows: <br />Full-length pants and shirt; <br />Sturdy steel-toe work boots; <br />Hard hat; <br />Safety glasses. <br />Modified Level D (used as appropriate) is as follows: <br />Regular Tyvek coveralls; <br />Outer gloves: leather, cotton, or nitrile; <br />Inner gloves: latex or nitrile; <br />Sturdy steel-toe work boots; <br />Hard hat; <br />Safety glasses. <br />Level B (used as appropriate) is as follows: <br />Positive-pressure, full-face piece, self-contained <br />breathing apparatus (SCBA) or positive-pressure <br />supplied air respirator with escape SCBA <br />(NIOSH-approved); <br />Disposable chemical-resistant coveralls <br />(Polycoated Tyvek); <br />Outer gloves: neoprene or nitrile; <br />Inner gloves: latex or nitrile; <br />Sturdy steel-toe work boots; <br />Petroleum-resistant covers over work boots; <br />Hard hat. <br />Level C (used as appropriate) is as follows: <br />Half-face air purifying, canister equipped <br />respirator (NIOSH-approved) equipped with <br />Organic Vapor/HEPA cartridges/filters; <br />Regular Tyvek coveralls; <br />Outer gloves: leather, cotton, or nitrile; <br />Inner gloves: latex or nitrile; <br />Sturdy steel-toe work boots; <br />Hard hat; <br />Decontamination Procedures <br />Drilling and sampling equipment will arrive decontaminated and clean. All downhole soil and groundwater <br />sampling equipment (e.g., sampling tubes, split spoons, hand augers, Hydropunch, etc.), tools, purge pumps, water <br />level indicators, etc. will be decontaminated before, between, and after use with Alconox or an equivalent <br />phosphate-free detergent solution to reduce the risk of cross-contamination.
