dre April 2013 <br />Project No. 1301-0621 associates, Inc. <br />ENGINEERS, GEOLOGISTS d, <br />ENVIRONMENTAL SCIENTISTS <br />Fire and Explosion. Gas or sewer lines can contain hazardous levels of explosive or <br />toxic gases, which may pose a fire risk. The risk of fire on site may also stem from the <br />presence of vegetation, heat and fuel sources from construction equipment and site vehicles, or <br />from the presence of combustible gases or vapors in contaminated soil and/or wells. The <br />potential exposure to fire and explosion hazards is considered low. <br />Traffic Hazards. Work activities along roadways, parking areas, and entrance and exit <br />areas create exposure to traffic hazards. Field activities will occur near a loading/unloading <br />area of the facility. Vehicle traffic does occur in the area of field activities. The potential <br />exposure to traffic hazards is considered moderate. Therefore, appropriate measures, le <br />cones, barricades, will be employed to protect workers from loading/unloading area traffic. <br />GENERAL SAFETY RULES <br />There will be no eating, drinking, or smoking within the safe perimeter set up. <br />Fire extinguishers will be onsite on or near Padre Associates, Inc.'s vehicle. <br />A first aid kit is located within Padre Associates, Inc. vehicle. <br />EQUIPMENT <br />Personal Protective Equipment. On the basis of the evaluation of potential hazards, <br />the level of protection deemed appropriate for this site is Level D. If organic vapor <br />concentrations in the breathing zone exceed 40 parts per million by volume (ppmv), EPA Level <br />C personal protective equipment will be used. These concentrations are based on personnel <br />exposure limits (PELs) and threshold limit values (TLVs) of the various contaminants <br />anticipated, with some consideration given to possible contaminants encountered in <br />combination. <br />Level D equipment includes: <br />hard hat <br />steel toe and shank boots <br />safety glasses or goggles <br />gloves <br />Level C equipment includes: <br />full or half face respirator <br />dual cartridge with organic vapor/acid gas hepa filtration <br />steel toe neoprene boots <br />Tyvek suits <br />latex inner gloves <br />PVC outer gloves <br />duct tape <br />13 0621 _Kaiser Stockton_TWP-HSP <br />- A5 -
