See basic NFPA 704 diamond documentation below.

This box has one additional parameter: |caption=Caption goes here

This template uses TemplateStyles:

Template:NFPA 704 diamond/styles.css

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.

Health code, 0-4 or - (hyphen for blank)
Flammability code
Instability (reactivity) code ("R=" is also allowed)
Special code W, OX, W+OX, ..., or - (hyphen for blank)
References. Add the <ref> ... </ref> tags.
Set =no to show text instead ('RA' only. Default: =yes, show image)
background color (e.g., =yellow or =#ff7623)
}}

Input options

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)

Parameters |H=, |F=, |I= 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)

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).

Special hazard options

`\|S=W`	`\|S=OX`	`\|S=W+OX`	`\|S=SA`	`\|S=-` (hyphen)
W	OX	W OX	SA

`\|S=ACID`	`\|S=ALK`	`\|S=BIO`	`\|S=COR`	`\|S=CRYO`
ACID	ALK	BIO	COR	CRYO

`\|S=RA` `\|showimage=<default>`	`\|S=RA` `\|showimage=yes`	`\|S=RA` `\|showimage=no`
		RA

For W enter |S=W.

For W OX enter |S=W+OX, |S=W OX or |S=WOX.

The "Special" quarter is sometimes called "Other".

Unknown codes (error)

The diamond template checks for unknown codes.

`=abc`	`= `	`=abc` `\|cat=no`
`H=abc` NFPA code error. `F=klm` NFPA code error. `I=pqr` NFPA code error. `S=XYZ` NFPA code error.	`H=` NFPA code error. `F=` NFPA code error. `I=` 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 (0). 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

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>

^[1] 2 2 2

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).

List of codes

Code descriptions ( v )
input type	quarter	code	text

code	H	0	Health 0: Exposure under fire conditions would offer no hazard beyond that of ordinary combustible material. E.g. sodium chloride
code	H	1	Health 1: Exposure would cause irritation but only minor residual injury. E.g. turpentine
code	H	2	Health 2: Intense or continued but not chronic exposure could cause temporary incapacitation or possible residual injury. E.g. chloroform
code	H	3	Health 3: Short exposure could cause serious temporary or residual injury. E.g. chlorine gas
code	H	4	Health 4: Very short exposure could cause death or major residual injury. E.g. VX gas
code	F	0	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). E.g. diesel fuel
code	F	3	Flammability 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 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	I	0	Instability 0: Normally stable, even under fire exposure conditions, and is not reactive with water. E.g. liquid nitrogen
code	I	1	Instability 1: Normally stable, but can become unstable at elevated temperatures and pressures. E.g. calcium
code	I	2	Instability 2: Undergoes violent chemical change at elevated temperatures and pressures, reacts violently with water, or may form explosive mixtures with water. E.g. white phosphorus
code	I	3	Instability 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. hydrogen peroxide
code	I	4	Instability 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, W, <s>W</s>	Special hazard W: Reacts with water in an unusual or dangerous manner. E.g. sodium, sulfuric acid
code	S	W+OX, WOX	Special hazard W+OX: Reacts with water in an unusual or dangerous manner AND is oxidizer
code	S	ACID	Special hazard ACID: Acid
code	S	ALK	Special hazard ALK: Alkaline
code	S	BIO	Special hazard BIO: Biohazardous. E.g. smallpox virus
code	S	COR	Special hazard COR: Corrosive; strong acid or base. E.g. sulfuric acid, potassium hydroxide
code	S	CRYO	Special hazard CRYO: Cryogenic
code	S	POI	Special hazard POI: Poisonous
code	S	RA	Special hazard RA: Radioactive. E.g. plutonium

Colors used

Blue	Red	Yellow	White
1	4	3	SA
`#6691ff`	`#ff6666`	`#fcff66`	`#ffffff`

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

Known issues

Is there an ENGVAR-like switch needed, eg for the order of °C - °F temperatures? (Currently, °C is first)
For documentation, could use a diamond with the four letters in the quadrants.
The non-standard S (on white) codes should be complete, and maybe listed for attention.
