"Blind" samples are submitted by the laboratory' s quality <br /> assurance officer on a weekly basis. These are prepared from <br /> National Bureau of Standards or EPA reference standards. <br /> Safety Program <br /> It is important that the on-site safety program be designed to <br /> protect the worker from direct skin contact, inhalation, or ingestion <br /> of potentially hazardous materials that may be encountered at the <br /> site. It should also familiarize the worker with appropriate first <br /> aid procedures in the event of a harmful exposure. In order to do <br /> this, the potentially hazardous properties of the materials and their <br /> toxic effects must be understood. Brown and Caldwell has reviewed <br /> the results of prior chemical analyses performed on samples obtained <br /> from the similar sites. This informatiion was used to develop the <br /> following site safety plan for this work. <br /> Personnel Protection <br /> The personnel protection plan for this project is designed to <br /> prevent sampling personnel from exposure to petroleum hydrocarbons <br /> which might be encountered on site . <br /> The following clothing shall be worn by all on-site personnel: <br /> 1. Hard hat with optional face shield. <br /> 2. Steel-toed boots. <br /> 3. Gloves. <br /> To prevent direct skin contact, the following protective clothing <br /> will be available for personnel working on site and shall be worn if <br /> deemed necessary by the on-site hydrogeologist: <br /> 1. Breathable tyvek coveralls or cotton coveralls. <br /> 2. Disposable vinyl gloves, changed between samples. <br /> 3. Goggles to guard against splash unless face shield is used. <br /> No eating, drinking, or smoking will be allowed within 50 feet of <br /> the drilling and sampling operations. No contact lenses will be worn <br /> by sampling personnel. <br /> First Aid <br /> On-site personnel will be informed of the symptoms related to <br /> exposure to significant concentrations of gasoline. Immediate <br /> symptoms include irritation of the respiratory passages; headache; <br />
