FLAMMABLE FUEL. Do not allow smoking within 100 feet (30.50 meters)

of the storage area. Post NO SMOKING signs around the area. Avoid

getting fuel on the body or clothing. If clothing becomes saturated with

fuel, remove the clothing immediately and wash body with hot soapy water

and soak clothing in soapy water. Avoid spillage of fuel. When spillage

occurs, cover the affected area with dry soil to reduce its rate of vaporization.
