" NFPA 704: Standard System for the Identification of the Hazards of Materials for Emergency Response " is a standard maintained by the U.S. -based National Fire Protection Association. First "tentatively adopted as a guide" in 1960, [1] and revised several times since then, it ...
NFPA 704 diamond. This template produces a NFPA 704 safety square with optionally four hazard codes. It is designed to be used in a table. Primary use is through { { Chembox }}, the { { NFPA 704 }} box and { { OrganicBox complete }} (chemical data pages). When used stand-alone (outside of a table), consider the { { NFPA 704 }} box.

They signed Calvin Ridley to a huge deal, added Tony Pollar d to their backfield and selected Alabama offensive tackle JC Latham with the seventh pick in the draft. Those are sizable investments ...
Diamond is the hardest known material to date, with a Vickers hardness in the range of 70–150 GPa. Diamond demonstrates both high thermal conductivity and electrically insulating properties, and much attention has been put into finding practical applications of this material. However, diamond has several limitations for mass industrial ...
