Anheuser-Busch/Arch Road <br /> Site Safety Plan <br /> February 11, 1992 <br /> 4.3.3 Sample Preservation: <br /> When hydrochloric acid is used; skin and eye contact can occur. <br /> This hazard can be reduced with the use of Nitrile butyl rubber <br /> or neoprene gloves and the use of safety goggles. <br /> 4.3.4 Cleaning Equipment: <br /> Skin and eye contact with methanol, Alconox, or other cleaning <br /> substances can occur while cleaning equipment. This hazard can <br /> be reduced with the use of Nitrile butyl rubber or neoprene <br /> gloves and the use of safety goggles. <br /> 4.3.5 Confined Space: <br /> Manholes, subsurface vaults and sheds are examples of confined <br /> spaces that may lack adequate ventilation. Organic and/or <br /> combustible vapors may be trapped resulting in a lack of oxygen <br /> (anoxia) and/or overexposure to vapors. When site work takes <br /> place in a confined space the air must be monitored for (a) <br /> oxygen level, (b) flammable vapors, and (c) toxic vapors. The <br /> following air monitoring procedures must be followed before <br /> entering a confined space. <br /> a. OXygen Level: Monitor for % Oxygen with an OZ/LEL meter to <br /> ensure a minimum oxygen level of 19.5%. Oxygen level <br /> monitoring will be done at the top, middle and bottom of <br /> the enclosed space to determine if there is a minimum <br /> acceptable oxygen level of 19.5% PRIOR to entry. <br /> If oxygen is less than 19.5%, do not enter the space. <br /> 10 . <br />
