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
Toxic Substances Control Act of 1976 safety standard. However, the EWG regarded CSIA as moving in the right direction because the EPA would have gained more authority to review existing chemicals and order companies to provide any relevant safety data about a specific chemical in question. Earthjustice further called for the final result of TSCA reform to be one that adequately protected workers continually exposed to hazardous chemicals, vulnerable populations, and communities most at risk because of high exposure to toxic chemicals. The CSIA would have required states to co-enforce any requirements laid out by the EPA, i.e. to have funding and man-power to enforce all
