When applying chemical fungicides or herbicides on your lawn, protect yourself by wearing long-sleeved shirts, long durable pants, closed-toe shoes, goggles, thick neoprene gloves, and a respirator. These chemicals will, at the very least, irritate your lungs, while some may even burn your skin. Be sure to follow the manufacturer's instructions.

Also, keep your synthetic weed control fluids away from kids, this stuff can be seriously harmful.
