Field operations personnel will be cautioned to inform each other of the non- <br /> visual effects of the presence of toxics, such as, <br /> Headaches <br /> Dizziness <br /> Nausea <br /> Blurred vision <br /> Cramps <br /> Irritation of eyes, skin, or respiratory tract <br /> Changes in complexion or skin discoloration <br /> Changes in apparent motor coordination <br /> Changes in personality or demeanor <br /> Excessive salivation or changes in pupillary response <br /> Changes in speech ability or pattern <br /> Exposure to Cold Temperature: Hyperthermia can occur when a person is working in a <br /> cold environment. Work schedules will be adjusted to provide sufficient rest periods in a <br /> heated area for warming up. Thermal protective clothing, such as wind and/or moisture <br /> resistant outer wear is recommended to be worn. Dehydration, or loss of body fluids, <br /> occurs in a cold environment and may increase the susceptibility of the worker to cold <br /> injury due to a significant change in blood flow to the body extremities. Warm sweet <br /> drinks and soups should be provided at the work site to provide caloric intake and fluid <br /> volume. The intake of coffee should be limited. <br /> Exposure to Hot Temperature: Heatstroke and heat exhaustion can occur when a person is <br /> working in a hot environment, sitting in a hot automobile, or over-exerting while <br /> performing field duties such as monitoring or surveying. Work schedules will be adjusted <br /> to provide sufficient rest periods in a shaded area for cooling purposes. Avoiding direct <br /> sunlight will not necessarily protect a person from the ill effects of heat. It is possible to <br /> suffer heatstroke even when the temperature is fairly low. Excessive humidity can induce <br /> over-heating by interfering with the perspiration evaporation-cooling process of the body, <br /> causing excessive sweating and the loss of salt and water. <br /> Heat Exhaustion <br /> The signs and symptoms of heat stroke or heat exhaustion are variable with the <br /> developing condition. Headache,a light to severe dizziness, some mental <br /> confusion or loss of physical coordination; and pale, sweaty skin are all <br /> symptoms of heat exhaustion. To care for a person who has suffered heat <br /> exhaustion, move them to a cool place and keep them at rest. Fan the patient's <br /> body to expedite the cooling process, and watch for the signs of shock. If the <br /> patient becomes unconscious, or fails to recover rapidly, alert the local EMS <br /> service. <br /> 5 <br />
