Always wear goggles, gloves, long sleeve shirt, long pants, and full foot protection when spraying. Never use any tool to remove the pump if there is pressure in the sprayer. Never stand with your face or body over top of the tank when pumping or loosening the pump to prevent ejecting pump assembly and/or solution from striking and injuring you.
