NFPA 704 safety squares on containers of ethyl alcohol and acetone. "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.
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 {{}}, the {{}} box and {{OrganicBox complete}} (chemical data pages).
A sign that uses a yellow 'Instability' bar, which was never part of HMIS. ("Instability" is a NFPA 704 term.) Prior to 2002, with HMIS' third edition (HMIS III), both systems used the same colors, blue, red, yellow and white, and used the same criteria for 'flammability'/'Fire Hazard' and 'reactivity'.
Flammability 0: Will not burn. E.g. water code F: 1: Flammability 1: Must be pre-heated before ignition can occur. Flash point over 93 °C (200 °F). E.g. canola oil code F: 2: Flammability 2: Must be moderately heated or exposed to relatively high ambient temperature before ignition can occur. Flash point between 38 and 93 °C (100 and 200 °F).
Hazard pictograms form part of the international Globally Harmonized System of Classification and Labelling of Chemicals (GHS). Two sets of pictograms are included within the GHS: one for the labelling of containers and for workplace hazard warnings, and a second for use during the transport of dangerous goods.
The pictogram for harmful substances of the Globally Harmonized System of Classification and Labelling of Chemicals.. The Globally Harmonized System of Classification and Labelling of Chemicals (GHS) is an internationally agreed-upon standard managed by the United Nations that was set up to replace the assortment of hazardous material classification and labelling schemes previously used around ...
Flammability of furniture is of concern as cigarettes and candle accidents can trigger domestic fires. In 1975, California began implementing Technical Bulletin 117 (TB 117), which required that materials such as polyurethane foam used to fill furniture be able to withstand a small open flame, equivalent to a candle, for at least 12 seconds.

In the U.S., an NFPA diamond is used to identify chemical hazards such as flammability, corrosivity, toxicity, and reactivity. This label is made up of four colour-coded fields: red (flammability), blue (health hazard), yellow (chemical reactivity), and white (special hazard). The numbering ranges from 0 to 4 (for colours except white), with 0 ...
