Work Plan—Site Sampling Page 4 West Weber Site-Stockton GPE Project 536.2 III WORKER PROTECTION Chemical Exposure Prevention Workers will be protected from direct chemical exposure by wearing appropriate personal protective equipment (PPE). Direct contact with possibly contaminated soil will be avoided by the use of boots and gloves when contacting soil or other materials that could contain elevated levels of hazardous chemicals. If wind or mechanical disturbance creates dusty conditions, sampling activities will not be continued until dusty conditions abate. Heat Stress Monitoring& Prevention Depletion of body fluids and body electrolytes should be avoided. Personnel shall eat and drink properly on and off the job during this project. Water shall be provided and drinking encouraged. The work schedule shall be adjusted as needed to respond to particularly hot days. The working day may be curtailed if temperatures reach 90 degrees. Any personnel who experience light-headedness, excessive fatigue, headaches, nausea, clamminess or other signs of heat stress will cease work, rest in a shady area, and drink water. If symptoms persist for more than a few minutes, work will cease for the day and medical attention will be sought. Noise Exposure Protection Workers in close proximity to engines or other equipment producing continuous noise in excess of 90 dB shall wear hearing protection. Workers exposed to impact noise in excess of 115 dB shall wear hearing protection. Neither of these situations are anticipated with any of the equipment that will be used. General Worker Safety Protection At a minimum, boots and gloves will be worn during sampling. During machine drilling operations, workers will don safety boots and hardhats. When conditions are dusty, sampling operations will be terminated. Medical Surveillance In view of the very limited number of personnel involved, workers will need to be responsible for self-monitoring. They should be aware of the symptoms of heat stress as described above, and report any symptoms to the site safety manager, and take steps to deal with the symptoms. In addition, if more than one person is on the site, they will be instructed to observe signs of heat stress in co-workers. Decontamination Personnel and equipment leaving the Exclusion Zone shall undergo decontamination on-site. This will consist of washing areas of skin that have been exposed to possibly contaminated soil with soap and water. Used nitrile gloves will be placed in a plastic bag, sealed, and disposed of 2937 Veneman Avenue, Suite B240 Geo-Phase Environmental Inc. Phone: (209)569-0293 Modesto, Ca 95356 Fax: (209)569-0295
