HAZARD ANALYSIS The potential hazards to personnel working at this site have been identified as physical hazards of working around heavy equipment, noise and heat and/or cold stress. The potential hazard is described below. Physical Hazards On-site hazards are working around heavy equipment, noise and possible heat and/or cold stress. While working at the site, the field personnel must be aware of heavy equipment movement and general traffic, and maintain communications or eye contact with the equipment operator. Field personnel will exercise extreme caution during the frilling activities and will take precautions to stay out of the equipment path. Noise levels around heavy equipment may exceed comfortable range in which hearing protection will be required. Heat Stress The potential for heat stress is a concern when field activities are performed on warm, sunny days, and is accentuated when chemical protective clothing is worn. Heat stress prevention measures and monitoring will be implemented if site temperatures are above 70 degrees Fahrenheit. Precautions to prevent heat stress will include work/rest cycles so that rest periods are taken before excessive fatigue occurs, and regular intake of water to replace what is lost from sweating. Heat stress due to water loss can be prevented. To prevent dehydration, water intake must approximate sweat loss. An initial work/rest cycle of one hour work and fifteen minutes rest is recommended for protection of the staff when the heat stress hazard is high. The recommended cycle will be adjusted up or down based upon worker monitoring, environmental conditions, and the judgement of the site safety officer. Cold Stress Cold stress will be a potential hazard during the field activities when the air temperature at the site is below 40 degrees F. Precautions will be taken to prevent cold stress including wearing cold-protective clothing appropriate for the level of cold and physical activity, changing underclothing if it becomes wet and establishing a work and warm regimen.
