sive heat and don't smoke when using it. Failure to do so could

cause serious injury. If you become dizzy while using cleaning

contact with skin or clothes is made, flush with large amounts of

water. If contact with eyes is made, wash eyes with water immedi-

ately, and obtain medical aid immediately.

ure to do so could cause serious injury to eyes and possible blind-

ness. If you hurt your eyes or if a foreign object is blown into

your eyes, seek medical attention immediately.
