Gallium highly reactive (rubidium and caesium) nor highly toxic (mercury) and can therefore be used in metal-in-glass high-temperature thermometers. It is also notable for having one of the largest liquid ranges for a metal, and for having (unlike mercury) a low vapor pressure at high temperatures. Gallium's boiling point, 2673 K, is more than eight times higher than its melting point on the absolute scale, the greatest ratio between melting point and boiling point of any element. Unlike mercury, liquid gallium metal wets glass and skin, along with most other materials (with the exceptions of quartz, graphite, and Teflon), making it
Explosives safety and surrounding facilities exposed to A&E facilities is a key element of the explosives/toxic chemical site planning process. This management process also ensures that risks above those normally accepted for A&E activities are identified and approved at the proper level of command. Explosives Safety Specialist must often travel to different storage sites to verify that the military installation is meeting the service explosives safety regulations. Explosives Safety Specialist often works with other safety professionals. They are required to know OSHA, EPA, NFPA and other consensus standards when looking at safety and if these regulations are stricter than their service regulation
