How do you fight an electrical fire if have no fire extinguisher?
First, if you have any doubt that you can fight it safely, get out and call 911. If it is a small fire and you can safely reach the plug-in, unplug it. If not, go to the breaker box and cut off the main breaker. Remove any combustible material that may be next to the fire that the fire could spread to. Stay away from the smoke, it could contain toxic gases. Once the power is off, get a thick blanket and throw over the appliance. This should starve the fire of oxygen and it should go out. It will still be hot and could reignite so get it outside and pour water on it.

How many B1 fire extinguishers must motorboat a between 26 and 40 feet have aboard?
Motorboats between 26 and 40 feet must have two B-I extinguishers.B-I is either 2 pounds dry chem, 4 pounds CO2 or 6 quarts foam. NOTE: According to US Coast Guard regulations. 46 CFR 25.30.
NOTE: When a fixed fire extinguisher system is installed in the machinery space(s), it will replace one B-I type portable extinguisher.
Under Canadian CG regs, it would need one Class B-II extinguisher, even if it is not a motorboat, if it has liquid or gas-fueled heating or cooking aboard, for boats 8 to 12 meters (26.2 to 39.4 feet). A B-II is a 5-pound dry chemical with proper approval labels.
Canadian regulations have the same requirement for powerboats 8 to 12 meters, or for any boat that size with liquid or gas-fueled heating or cooking.
If it is not a powerboat, but it has liquid or gas-fueled heat or cooking, under Canadian regulations it would still need at least one Class B-II extinguisher, if it is over 8 meters (26.2 ft) and under 12 meters (39.4 ft). If it were exactly 26 ft, it would only need one class B-1 extinguisher.

Is fire extinguisher is needed for a small room?
Fire extinguishers are required according to local, state or federal fire codes, as may apply to the particular structure. Some "small rooms" may need their own extinguishers.
Under the NFPA 1 Fire Code, nearly all types of occupancies other than one- and two-family dwellings are required to have at least one portable fire extinguisher, even if there are fire alarms, fire sprinklers and "fire-proof" construction. NFPA 1 (2009): Table 13.6.2 Portable Fire Extinguishers Required (by occupancy use).
For example:
There must be no less than one fire extinguisher within 75 feet of any Class A Hazard and within 30 or 50 feet of any Class B hazard (depending upon size of extinguisher and type of hazard). NFPA 1 (2009): Table 13.6.8.2.1.1 Fire Extinguisher Size and Placement for Class A Hazards and Table 13.6.8.3.1.1. for Class B Hazards.
Why should you not use a water fire extinguisher on a petrol fire?
Do not use water on any flaming liquids because they may float on the water and simply spread the fire, or the water pressure may cause the burning material to spread. In some cases, flaming liquid covered with water can cause a massive explosion of steam and flaming liquid to spread the fire rapidly.
The use of water on petrol (liquid fuel) fires should be avoided for several reasons. Initially, the fuel is a liquid, and the application of a stream of water will splash it and spread the fire. Another consideration is that the water won't cool the burning fuel sufficiently to put it out. It also won't cut off the oxygen supply as the liquid will not be "blanketed" by the water. (Fuel floats on water as it is less dense.)
Recall that the fire triangle includes fuel, air (oxygen) and heat. Water will not "break" any of the legs of the triangle if the fire is based on burning fuel. Water with a foaming agent or another extinguishing agent must be used to control a fire of burning liquid fuel.
Because if you did, then the petrol would spread and cause an even bigger fire, which would be bad!!!
When using a fire extinguisher to put out a fire you should sweet at what part of the fire?
The bottom or base- where the fuel is located.
What does the date on fire extinguisher mean?
A fire extinguisher requires routine maintenance and testing to ensure proper function during an emergency. The date, which is often found on a service tag attached to the extinguisher, will either indicate the date of the last test, or the date on which re-certification is required. For most areas in North America, Extinguishers in commercial buildings are to be inspected and re-certified annually, and extinguisher systems in food preparation/commercial kitchen areas semi-annually.
In many cases, there is a chart on the flip-side of the service tag, which is to be signed monthly by a responsible person from wherever the extinguisher is installed. This person is often an in-house health and safety representative, who simply checks that the pressure gauge of the extinguisher is in the green or 'charged' zone, and that the extinguisher is accessible and visibly in good condition.
Can you block access to a wall mounted fire extinguisher?
Yes, you can, but it would violate the fire code and common sense.
Is nitrogen gas used in a Dry powder fire extinguisher?
Yes, portable dry chemical fire extinguishers are pressurized by means of nitrogen (expellant gas used to discharge the extinguishing agent from its container). Carbon dioxide can also be used as expellant gas. Usually carbon dioxide is used for temperatures ranges of 0oC to +49oC, and nitrogen for extreme temperature ranges of -54oC to +99oC.
