The procedure for sampling lead fumes in air involves air sampling pumps, designated as static pumps, in fixed positions along the range. These provide a background measurement and indicate the drift of lead fumes, indicative of the ventilation system. Other pumps, called personal pumps, are worn by the instructors, with the filter sampling the air placed as close to the breathing zone as possible to give indications of the lead fume inhaled. In addition, there is a program to monitor the lead levels in the blood of all officers involved in firearms instruction. Furthermore, the laboratory conducted tests of 'nyclad' ammunition, claimed to emit far fewer lead compounds than do conventional bullets. A marked drop in lead pollution was noted with the use of the inert nylon jacketed bullets, although the English test did not find the 61 to 89 percent reduction in lead fume emission claimed by initial American experiments.
