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
Centre for Fire, Explosive and Environment Safety processing and storage dumps and the design, testing and evaluation of safe explosive storage houses. Additionally, it trains armed forces personnel and DRDO scientists in the safe use of explosives and ordnance, and enforces compliance of safety rules. Simulation and risk modeling is also carried out, in order to aid in Disaster Management. Environment Safety - CFEES develops treatment and disposal techniques for hazardous Heavy Metal Wastes, as well as Photodegradable Polyethylene for use as packaging material at high altitudes, which prevents the pollution in mountainous areas where the Indian Army operates, such as Kargil and Siachen. CFEES also plays
