The pit should be 6 to 8 in. (152.4 to 203 mm) deep and approximately 8 ft
(2.44 m) wide. The pit extends the full width of the range. If silica dust
cannot be eliminated by the ventilation system or by the use of wetted send,
the sand pit is prohibited.
2.1.5.4 Water Pit. A water pit may be constructed using the same dimensions
as a sand pit except deep enough to hold 10 to 12 in. (254 to 304.8 mm) of
water for pistol calibers and a minimum of 24 in. (609.6 mm) of water for
centerfire rifle calibers. Water is safer from a lead and silica-dust
pollution standpoint. Consideration should be given to the addition of common
laundry bleach to the water to retard algae growth.

range officer.
