0 0 <br />Contamination Reduction Zone: A formal decontamination zone <br />should not be required during the preliminary investigation. <br />However, an area will be designated in the event extreme <br />gasoline contamination is encountered. The decontamination <br />zone will be an area where personnel can clean protective <br />equipment. A waste container will be placed outside of the <br />exclusion zone so contaminated equipment can be placed inside <br />and covered. <br />Support Zone: A Support Zone, the outermost zone, must be <br />defined for each field activity. Support equipment is located <br />in this uncontaminated or clean area. Normal work clothes are <br />appropriate within this zone. The location of this zone depends <br />on factors such as accessibility, wind direction (it should be <br />up wind of excavation), and resources (e.g. roads, utilities, <br />shelter). <br />Decontamination Procedures <br />Petroleum hydrocarbon liquids and vapors are anticipated. Due to the <br />volatile nature of hydrocarbons that may be encountered during the <br />initial excavation and sampling operations, decontamination of <br />equipment and vehicles will be of minimal importance since the <br />volatile hydrocarbons will rapidly vaporize. Therefore, no formal <br />decontamination procedure will be followed with the exception of <br />general cleaning no eating, drinking or smoking will be permitted in <br />the exclusion zone. All personnel involved in work activities will <br />be instructed to wash their hands, face, neck and forearms at the end <br />of the work day. soap, water and towels will be provided at the site <br />for this purpose. The field personnel will also be instructed to <br />shower at home at the end of each work day. <br />As work progresses, the nature of materials handled and the extent of <br />contamination may possibly require formal decontamination procedures <br />and delineated work/clean zones. However, we do not expect that such <br />formal procedures will be necessary at this site and will only <br />proceed at the Safety Officer discretion. In the event extreme <br />contamination is encountered, decontamination of personnel, equipment <br />and vehicles will be important to insure that contamination dose not <br />spread to unsuspecting people and property. Personal decontamination <br />mainly involves personal hygiene. Contamination should not be <br />present on the skin if the proper protective methods specified in <br />this plan are used. However all field personnel will be instructed <br />to follow these guidelines to insure that contamination dose not <br />remain on equipment, sample containers or in contact with their <br />bodies. <br />i <br />
