Know as much as possible about the types of pumps you will be working with. Follow specific instructions on instrument operations provided by the manufacturer. Make sure all equipment is in good operating condition. Check all equipment and power sources prior to leaving the office. Before using any pump, be familiar with its operation, and for installed pumps, review procedures in the field folder for the site.
Electrical sources are potential hazards.
Electrical sources, batteries, generators, or existing AC can cause shocks. Respect the energy source and properly ground all instruments. Pumps and generators must be fueled and oiled away from the area of operation. If the site is in a well house or spring house, watch for low doorways and beams inside. As you enter, check for rotten or loose floor boards, slippery floors, snakes, and biting or stinging insects.
