Hi Sarah...
I take it the first sentance has been "assigned" and now you have to complete the report.
I think I would focus mainly on what can happen when you use the wrong extinguishing agent for the job and some of the risks associated with the various firefighting agents.
First and foremost is water. Water is probably the most prevalent fire extinguishing agent because we have it in abundance. Let's face it, even responding fire personnel's number one agent is water. While it's true that they also carry chemical extinguishers, foam, and other agents, water is the number one choice for extinguishing large scale fires.
Where can water cause a problem? Well, there are a variety of chemicals that do not react well with fire. A chemical storage facility, for example, may have hazards where using water could not only make the fire worse, it could cause reactions that could have serious environmental consequences from air quality to run-off.
On a smaller scale, using water to attempt to extinguish a flammable fuel fire can often spread the fuel, making the fire worse. (Fuels tend to float on the top of water.) Foams, and chemical agents would be the best choice.
Flammable metals have to be extinguished with sand or special "class D" chemicals. Again, water could just make matters worse.
Water and water-based foams also conduct electricity. If the fire is electrical, an electrocution risk is present. Dry chemcial and gaseous agents should be considered if the power cannot be shut off. Even when the power is shut off, certain pieces of equipment can carry a residual electrical charge.
Chemical agents can produce an asphyxiation risk when used in confined spaces. Carbon Dioxide lowers the oxygen level if used in small spaces. Halogenated agents can break down into potentially hazardous gasses. Care should be taken when using extinguishers in small spaces.
Gaseous suppression systems that rely on Caron Dioxide can create a deadly atmosphere. The oxygen levels are so low and the CO2 levels are so high that an occupant entering the hazard, even after the fire is out, can be immediately overcome by the gas. There have been numerous fatalities tied to CO2 suppression systems in occupied spaces. NFPA has recently revised the standards (NFPA 12) to help combat this risk. (I always laugh at the scene in Crimson Tide, when Denzel Washingtons character activates the CO2 system in the galley and then proceeds to take off his air mask. If that had been a real CO2 system, he would have collasped!)
Hopefully, that gives you some ideas. If you need to bounce something off of me, feel free to contact me direct.

Coming from a firefighter, you might want to say that if the wrong type of extinguisher is used it may spread the fire further. This is common when dealing with water extinguisher and say fuel fires, grease fires etc. When you write about fire safety you may want to stick with things like unattended cooking. This was the biggest thing we had to deal with this past summer. More people have lost kitchens and caused more damage from leaving "just for a second" while something was on the stove. a 2 minute lapse in judgement cost over 15000 to one person last month.
Writing about fire safety should focus on the causes of accidental fires not the possible misuse of an extinguisher. There isnt too many misuses of an extinguisher you could really focus on other than horseplay. Just my opnion. You can do a search on the web for National Fire Prevention Week which should bring you some helpful hints up. Its coming up in Oct. Cheers.

You'd probably be better to write about the equipment used in fire safety. The different types of canasters ie water, carbon dioxide, powder, fire blankets. What type of fires they are used on, electrical, paper, you know things like that. Also the different types of fires, and the 4 components needed to start a fire, AIR, HEAT, CHEMICAL can't remember the last one. I have to go to fire safety lectures every year as i work for NHS. The things I've mentioned above are some of the things the lecturer mentioned. The lecturer is actually a chief fireman. Hope this helps.
You should also mention fire alarms and the importance of fire exits and why its important that they should be clearly signed and never blocked by things.

You should probably mention things like not throwing water in a cooking pan with boiling hot oil in it, the way a fire extinguisher is properly used, that the wrong use of a firehose can cause serious physical injuries and such.

Your fiancee began the hearth with overheated cooking oil. Why do I say that ? with the aid of fact a range is fullyyt steel, with useful few combustibles different than slightly wiring insulation. there is not any way for a range to burn with the help of itself, sparking or no longer. as quickly as the owner's insurer and the hearth branch look into the rationalization for this blaze, you are going to have a great difficulty in case you haven't any longer have been given renter's coverage. I project that they are going to be certain that the overheated oil is the rationalization for the blaze. no remember if or no longer the hearth replaced into began by twist of fate, you would be held responsible for the expenditures of the damages. (Now you comprehend what renter's coverage is for.) with the aid of hearth, i could guess that the premises would be declared uninhabitable, so which you will ought to circulate someplace else contained on the instant. the owner is decrease than no criminal duty to locate you different residing preparations in those circumstances. lower back, renter's coverage could cover those expenditures, in case you carry it. the owner's insurer will cover the damages for the owner, yet don't be greatly surprised while you're sued with the help of the insurer to recuperate the expenditures. do no longer propose to sound rude, yet this is the way it rather is going to probable finally end up. Relative to the computerized 'overheating', in case you knew that replaced right into a danger, why replaced into your fiancee no longer watching the cooking she replaced into making waiting ? Overheated oil basically does not flare up abruptly. It smokes appreciably till now it reaches a temperature the place it rather is going to ignite.

I don't think that is on point. If you are writing about fire safety you should talk about not leaving candles lit when you leave the room or about space heaters or about not overloading your circuits.
