ଛାଞ୍ଚ:NFPA 704 diamond
ଛାଞ୍ଚ ଡକ୍ୟୁମେଣ୍ଟେସନ୍[view] [ସମ୍ପାଦନ କରନ୍ତୁ] [ଇତିହାସ] [purge]This template produces a NFPA 704 fire diamond with optionally four hazard codes. It is designed to be used in a table. Outside of a wikitable, showing is not controlled.
Primary use is through {{Chembox}}, the {{NFPA 704}} box and {{OrganicBox complete}} (chemical data pages).

Input options[ସମ୍ପାଦନା]
Main rule: if the quarter must be blank, input is the hyphen, -. Do not depend on default behavior in this situation.
Basic 0–4 and - (hyphen)[ସମ୍ପାଦନା]
for |F=, |H=, |R=
| |||||
=0 |
=1 |
=2 |
=3 |
=4 |
=- (hyphen)
|
| |||||
|F=, |H=, |R= accept codes 0, 1, 2, 3, 4, -. Code - (hyphen) produces a blank ("no hazard code").
A blank can be set (enforced) by entering =-, a hyphen. This is the preferred way to reflect what the source states (don't depend on the default blank in this situation).
Default code (blank)[ସମ୍ପାଦନା]
= <blank>
|
|
All four codes default to blank, that is: no NFPA code is present or shown. There is no specific text (just a link to the NFPA color section). Note that a blank is not the same as code "0". Code "0" is an explicit statement, while a blank is the absence of any statement.
A blank can also be enforced by entering =- (hyphen). This is the preferred way to reflect what the source states (do not depend on default).
From the input, spaces and even newlines (all whitespace) are treated as blank. Note that = code produces an error, but entering the nbsp character (>= <) is accepted as a space (blank).

For W OX|S=W+OX, |S=W OX or |S=WOX.
The "Special" quarter is sometimes called "Other".
Unknown codes (error)[ସମ୍ପାଦନା]
The diamond template checks for unknown codes.
=abc |
= |
=abc|cat=no
|
F=abc NFPA code error. H=klm NFPA code error. R=pqr NFPA code error. S=XYZ NFPA code error.
|
F= NFPA code error. H= NFPA code error. R= NFPA code error. S=&NBSP; NFPA code error.
|
|
Articles with unknown codes are listed for maintenance (correction) in Category:Articles with unknown NFPA 704 code. Other pages (like this documentation) are not categorized, but have a message instead. This categorizing can be switched off by setting |cat=no
Note that = code produces an error, but entering the nbsp character (= ) is accepted as a space (blank).
Adding references[ସମ୍ପାଦନା]
References can be added using |ref=.
|ref=<ref>{{cite web|url=http://chemlabs.uoregon.edu/Safety/NFPA_White.html|title=More on white codes}}</ref>
The <ref> ... </ref> tags should be added. Multiple references can be entered. Depending on cell width, the links show above or next to the diamond. While technically possible to enter plain text, this is not supported (and this could be disallowed in the future).
Code description[ସମ୍ପାଦନା]
These are the title texts (mousehover texts), shown for a code used in the diamond. They are plain text; not links or styles can be entered.
| Code descriptions | |||
|---|---|---|---|
| input type | quarter | code | text |
| code | F | 0 | Flammability code 0: Will not burn. E.g., water |
| code | F | 1 | Flammability code 1: Must be pre-heated before ignition can occur. Flash point over 93 °C (200 °F). E.g., canola oil |
| code | F | 2 | Flammability code 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). E.g., diesel fuel |
| code | F | 3 | Flammability code 3: Liquids and solids that can be ignited under almost all ambient temperature conditions. Flash point between 23 and 38 °C (73 and 100 °F). E.g., gasoline) |
| code | F | 4 | Flammability code 4: Will rapidly or completely vaporize at normal atmospheric pressure and temperature, or is readily dispersed in air and will burn readily. Flash point below 23 °C (73 °F). E.g., propane |
| code | H | 0 | Health code 0: Exposure under fire conditions would offer no hazard beyond that of ordinary combustible material. E.g., sodium chloride |
| code | H | 1 | Health code 1: Exposure would cause irritation but only minor residual injury. E.g., turpentine |
| code | H | 2 | Health code 2: Intense or continued but not chronic exposure could cause temporary incapacitation or possible residual injury. E.g., chloroform |
| code | H | 3 | Health code 3: Short exposure could cause serious temporary or residual injury. E.g., chlorine gas |
| code | H | 4 | Health code 4: Very short exposure could cause death or major residual injury. E.g., VX gas |
| code | R | 0 | Reactivity code 0: Normally stable, even under fire exposure conditions, and is not reactive with water. E.g., liquid nitrogen |
| code | R | 1 | Reactivity code 1: Normally stable, but can become unstable at elevated temperatures and pressures. E.g., calcium |
| code | R | 2 | Reactivity code 2: Undergoes violent chemical change at elevated temperatures and pressures, reacts violently with water, or may form explosive mixtures with water. E.g., phosphorus |
| code | R | 3 | Reactivity code 3: Capable of detonation or explosive decomposition but requires a strong initiating source, must be heated under confinement before initiation, reacts explosively with water, or will detonate if severely shocked. E.g., fluorine |
| code | R | 4 | Reactivity code 4: Readily capable of detonation or explosive decomposition at normal temperatures and pressures. E.g., nitroglycerin |
| code | S | OX | Special hazard OX: Oxidizer. E.g., potassium perchlorate |
| code | S | W | Special hazard W: Reacts with water in an unusual or dangerous manner. E.g., cesium, sodium |
| code | S | (see code W)
| |
| code | S | SA | Special hazard SA: Simple asphyxiant gas. E.g., nitrogen, helium |
| code | S | COR | Special hazard COR: Corrosive; strong acid or base. E.g., sulfuric acid, potassium hydroxide |
| code | S | BIO | Special hazard BIO: Biohazardous. E.g., smallpox virus |
| code | S | CRYO | Special hazard CRYO: Cryogenic. |
| code | S | ACID | Special hazard ACID: Acid. |
| code | S | ALK | Special hazard ALK: Alkaline. |
| code | S | RA | Special hazard RA: Radioactive. E.g., plutonium |
| code | S | W OX | Special hazard W+OX: Reacts with water in an unusual or dangerous manner AND is oxidizer. |
| code | S | WOX | Special hazard W+OX: Reacts with water in an unusual or dangerous manner AND is oxidizer. |

Better not to use RGB colors named red, blue, yellow, because these produce a bad contrast with the text.
