Template talk:NFPA 704
Appearance
The NFPA fire diamond is produced by the {{NFPA 704}} template, in the format {{NFPA 704 | Health=# | Flammability=# | Reactivity=# | Other=( W or OX) }}, where # is a number from 0-4. Risks may be W (reacts violently with water) or OX (oxidizer).
So, e.g., for the toxic and corrosive oxidizer bromine trifluoride, one ought to use {{NFPA 704 | Health=3 | Flammability=0 | Reactivity=3 | Other=OX }}, as shown below.
