ITEC N <br /> S O ROL <br /> Entry into hazardous areas is limited to individuals who must work in those areas and are qualified to <br /> do so. Authorized visitors may be allowed to enter th work/exclusion zone only if they have read <br /> and understand this document and have agreed to abide by the requirements set forth, have the <br /> requisite OSHA certifications, are willing to follow the instructions of the SSO, and have been <br /> informed of the potential hazards and risks. <br /> Orange traffic cones and/or barricades are used to del neate an exclusion zone around the work site, <br /> including the excavation and power equipment. Barriers should be set at a 25-foot radius (as <br /> practical) around the site. <br /> At the end of a workday, excavations and work sites are secured to prevent accidental ingress by <br /> persons on foot or'in vehicles. On sites where a drill 'g is used, borings are covered or otherwise <br /> secured. Decontamination fluids are drummed, and the drums are properly marked and labeled. Soil <br /> cuttings are placed on and covered with plastic sheeting, and the sheeting labeled. Labeling includes <br /> at least the date, boring number, content of drum (i.e., soil, water, etc.), suspected contaminant, and <br /> depth interval, if appropriate. <br /> DECONTAMINATIO i PROCEDURES <br /> A high-pressure hot water washer is used for decontamination. Shovels, auger flights, and other <br /> equipment are decontaminated by brushing them and rinsing with the pressure washer. <br /> Boots and gloves are cleaned with a stiff bristle brush detergent, and water. Tyvek®coveralls and <br /> gloves are drummed on site and disposed of with drill cuttings. Waste and spent decontamination <br /> solutions are contained in drums on site. <br /> Respirators are washed, sanitized, and stored in a clean plastic bag or case. Each employee is <br /> r responsible for cleaning and maintaining his/her respirator. <br /> SAFE WORK PIP ACTICES <br /> The following general guidelines are presented. <br /> Eating, drinking, chewing gum or tobacco, and smoking are prohibited in the <br /> contaminated or potentially contaminated area or where the possibility for the transfer <br /> of contamination exists. <br /> t • A-12 <br />
