Fire Extinguishers

Sea water CAN be used to extinguish mountain fires but it isn't necessarily the best choice because it is salty enough to make it harder for plants to recover after the fire and because it may not be the closest source of large quantities of water. Also - scooping up water from the ocean with all the waves is more difficult than from a flatter body of water such as a lake.

*****

To add my bit: The water would do its job and help put out the fires. The downside is that the salt contents would affect the area and could inhibit future regeneration in the short term. It should be remembered that forest fires would happen naturally. It is only in death and the destroying of property that affects mankind. - nature will always recover. Sometimes humans believe that nature depends on them. Nature would get along quite happily without mankind.

You just click while holding it.

Usually one or more USCG-approved Class B-I or B-II are required.

According to US Coast Guard regulations (46 CFR 25.30):

At least one USCG-approved Class B-1 fire extinguisher is required on any powerboat with a permanently installed fuel tank.

A UL-listed 5-B:C extinguisher, with 2 pounds of dry chemical, may provide the basis for the extinguisher, but it must ALSO conform to USCG-approvals (proper corrosion protection, labeling, mounting bracket, etc).

A 4-pound CO2 extinguisher or 6 quarts foam extinguisher may also be rated for USCG B-1 service.

Powerboats over 26 feet may require additional extinguishers, as detailed in the related questions.

Up to 26 feet: one B-I extinguisher;

Over 26 but under 40 feet: two B-I extinguishers;

Over 40 feet but not over 65 feet: three B-I.

Note that two B-I extinguishers may be substituted for a B-II extinguisher.

NOTE: When a fixed fire extinguisher system is installed in the machinery space(s), it will replace one B-1 type portable extinguisher.

Fire extinguishers need to be located in an easy to reach place but not in the way of people trying to board or get off the boat. A good place would be near the pilots seat.

The Coast Guard requires that a class B-1 Coast Guard approved portable fire extinguisher in working condition be aboard every PWC

The act of smothering a fire is to prevent air (oxygen) from feeding the flames.

LETTER- type of fire it will extinguish

NUMBER- capacity. Higher the number, the bigger the fire it can extinguish.

Never ever use water on a gasoline fire or the fire will just spread. Smother it with sand, dirt, or a fire extinguisher specifically made for a gasoline fire.

Nitinol can be used in temperature control systems.

A class C fire extinguisher is used for electrical fires. A all purpose A, B, C extinguisher can also be used.

Where they are readily available

Fire blankets should be kept in easily accessible areas so that in the event of a fire they can be retrieved quickly. Fire blankets should be stored in locations where a fire hazard is most likely to occur.

This site provides training, including a quiz at the end to test yourself: http://ehs.okstate.edu/modules/exting/index.htm There are also videos on youtube that you may find helpful: http://www.youtube.com/watch?v=BLjoWjCrDqg&feature=related http://www.youtube.com/watch?v=gHiinGqhArw

Class A extinguishers are designed for "ordinary flammable materials" (organic solids such as paper and wood) but not liquids like gasoline, grease, electrical fires, or flammable metals.

At the base of the fire.

Direct the extinguisher at the base of the flames using a sweeping motion

Class B fire extinguishers are for fires of flammable liquids (grease, gasoline, oil, propane, paints). The numerical rating of "1" signifies the the number of square feet of the flammable fire that a non-expert could expect to put out.

So, a B1 extinguisher will help put a flammable material fire on only one (1) square foot before it runs dry.

Well, that means for OTHER PEOPLE that are answering your question to write in that space- but not a problem. As far as putting marshmallows in the fire- they are made of sugar, and will burn (they even catch on fire). You need a fork or a stick to roast marshmallows. The idea is to sort of toast them so they turn very light brown, not too much or they turn black. Really too much, it will have flames. REALLY too much, the melted, flaming marshmallow falls off the stick, sets fire to your homework, and there is a lot of yelling and screaming and mess to clean up. Marshmallow toasting is really meant for out of doors (campfire sort of thing). Listen to your parents, be careful with toasting, and never eat a marshmallow that is still on fire.
