Anyone can get lead poisoning; however, the risk to children under seven years old is the highest. The chemical analysis consists of measuring seven trace elements--arsenic, antimony, tin, copper, bismuth, silver, and cadmium-that typically are present in a bullet's lead alloy.
A general recommendation is that the temperature be held constant in the range of 21-23Â°C (69-73Â°F). In summertime when outdoor temperatures are higher it is advisable to keep air-conditioned offices slightly warmer to minimize the temperature discrepancy between indoors and outdoors.
External case temperature should always be below 27*C (80*F), with the best temperatures around 18*C (65*F). Internal air temperature should be around 40*C (104*F), except for heatsinks, which require lower temperatures. As long as you're using fans, don't be worried until case air temperature exceeds 55*C(130*F).
