Removed discharge time table

Pressurized extinguisher typical discharge time
1.1 kg	8 to 11 seconds
2.5 kg	13 to 18 seconds
4.5 kg	17 to 21 seconds
9.0 kg	20 to 26 seconds

If someone can find a place for this and some proper sourcing then it would be good to include. It sounds about right, but with data so specific, it would be good to have a source to back it up. Gigs (talk) 01:47, 25 May 2009 (UTC)

Images

Someone might want to add an image of the old Comet/grenade style single-use carbon tetrachloride extinguishers:

Add "Type of Extinguisher" column to USA table

Fire Class	Geometric Symbol		Pictogram	Intended Use	Type of Extinguisher (Extinguishing Agent)
A	Green Triangle		Garbage can and wood pile burning	Ordinary solid combustibles	Water; foam; dry chemical*
B	Red Square		Fuel container and burning puddle	Flammable liquids and gases	Carbon dioxide (CO2); halon**; dry chemical; aqueous film forming foam (AFFF)
C	Blue Circle		Electric plug and burning outlet	Energized electrical equipment	CO2; halon; dry chemical
D	Yellow Decagon (Star)		Burning Gear and Bearing	Combustible metals	Dry powder (suitable for the specific combustible metal involved)
K	Black Hexagon		Pan burning	Cooking oils and fats	Multi-purpose dry chemical (A, B, C)

_{*Dry chemicals, CO2 and halon can be used on Class A fires, but may not be effective on their own. They need to be supplemented with water.}

_{**Halon extinguishers are no longer made but some may still be in use. Dangerous gases are formed when halon is used to put out fires. Wear proper respiratory equipment, particularly in enclosed spaces. After use, do not allow anyone to enter the area until it has been well ventilated.}

Fire extinguishers as a metaphor

In Finnish, it is a common metaphor to say that someone is "the size of a fire extinguisher", meaning that said person is an infant, as infants are typically short. Should this be mentioned? JIP | Talk 19:38, 10 January 2012 (UTC)

Safety Data Sheets

The list included in the article refers to chemicals used for fire suppression; the delivery system may not be specifically a fire extingisher. These compounds mostly have their own articles. I propose a heavy deletion as being off topic here, adding the information to the compound's own article if necessary. --Old Moonraker (talk) 08:32, 24 April 2012 (UTC)

Classification

Are the UK classifications determined by EU regulations? If so, wouldn't it make more sense to have a Europe section rather than a UK section under Classification, with specific notes regarding the UK if needed? Mazz0 (talk) 20:12, 19 November 2012 (UTC)

Potassium aerosol?

I'm somewhat puzzled reading that the "Potassium Aerosol Particle Generator" indeed generates tiny particles of metallic potassium, given that it reacts explosively with water and steam, and that itself burns in air with a lillac flame... I think it might need a review.151.65.29.133 (talk) 23:10, 1 February 2013 (UTC)

History Section - Vandalism?

The history section currently (12-Jan-2016) says: "The modern fire extinguisher was invented by British Captain George William Manby in 1818; it consisted of a copper vessel of 3 gallons (13.6 liters) of pearl ash (potassium carbonate) solution contained within compressed air." If I may ask, what is "pearl ash solution contained within compressed air"?? Potassium carbonate is potash (note: pearl ash is also used for potash; I didn't know that; sodium carbonate is soda ash; even if the 1818 fire extinguisher was pressurized with compressed air, the grammar is all wrong. I hope someone can fix it up.AdderUser (talk) 11:13, 12 January 2016 (UTC)

Actual use of fire extinguishers should be included

I could find very little data on the actual use of fire extinguishers - clearly they save lives in some cases or they wouldn't be a requirement I presume? The closest I could find was a survey from 10th Feb 2022 from the FIA (Fire Industry Association) stating the results of a survey of all the industry forums in the UK. They had extinguishers being used 979 times over the year in the UK. — Preceding unsigned comment added by Mjaggard (talk • contribs) 11:22, 16 June 2022 (UTC)
