Open windows and use an exhaust fan, making sure air is exiting outside rather than being recirculated indoors. Take plenty of fresh air breaks. Be sure to use adequate skin, eye, and respirator protection. Do not eat, drink, or smoke while using hazardous products. Traces of hazardous chemicals can be carried from hand to mouth.
Smoking can start a fire if the products are flammable.
Clean up after using hazardous products. Carefully seal containers.
