  1. miracle whip is made from eggs..... and eggs are considered meat... =0
  2. I'm sure admin makes make from other sources such as selling t shirts,books, EMS apparel and whatever else admin has under his sleeves. But thanks for your 2 cents of a post.
  3. If an EMT,or EMT-P makes a mistake,causing death, doesn't the liability fall into the medical director/or physcian on calls hands? Or is it every man for themselves in the field. I never understood that portion.
  4. that story was so good can you tell it again?
  5. Gmail is what 2 or 3 gigs of storage space and its free LOL
  6. Probably have to pay 19.99 to get your message limit increased.
  7. You don't know enough about Canadian EMS to be even making random bullshit statements like this.
  8. http://www.emtcity.com/index.php?showtopic=14643
  9. 1a)Sorry to hear 2b)You need to bilingual with the proper certifications current,up to date. 3c)Quebec is NOT apart of Canada.
  10. why driver fail? granted that wasnt a standard bus,seatbelts anyone? it was nice to NOT see that fat ass land on the patient.
  11. 1)wiring problems 2)spark+gas 3)high rate of impact
  12. who hasn't done this? I mean come on give your head a shake people.......
  13. Thanks for the clarification. I was given the impression you had to spend a minimum of 5 years with BCAS before you could even apply for ACP. Thanks for the info.
  14. If your doing school here in Calgary @ SAIT, why not just register with ACOP and work in the province? Oh you don't want to deal with the non sense......now I understand... I think to work for BCAS you have to put in a minimum of 5 years as a part time PCP before you can advance or apply to a fulltime job pool. I'm not to sure about the process and it's entirety. Anyways,goodluck with your program. cheers
  15. Goodluck finding work,but if that's your dream then I suggest getting on it. The economy isn't getting any better,like mobey stated, most of the work for EMS providers is in the west. cheers
  16. In regards to older diesel engines in the way of operation fuel and air is mixed in a pre combustion chamber before it was injected into the cylinder. all of the mixing and injections are mechanically,not electronic or direct inject. a good example is the first gen 5.9L cummins 12 valve And for the new engines everything is pretty much computer control/injected. and the rest i stole from wiki, read here Starting In cold weather high speed diesel engines, which are mostly prechambered, can be difficult to start because the mass of the cylinder block and cylinder head absorb the heat of compression, preventing ignition because of the higher surface to volume ratio. Prechambered engines therefore make use of small electric heaters inside the prechambers called glow plugs. These engines also generally have a higher compression ratio of 1:19 to 1:21. Low speed and compressed air started larger and intermediate speed diesels do not have glowplugs and compression ratios are around 1:16. Some engines use resistive grid heaters in the intake manifold to warm the inlet air until the engine reaches operating temperature. Engine block heaters (electric resistive heaters in the engine block) connected to the utility grid are often used when an engine is turned off for extended periods (more than an hour) in cold weather to reduce startup time and engine wear. In the past, a wider variety of cold-start methods were used. Some engines, such as Detroit Diesel engines and Lister-Petter engines, used a system to introduce small amounts of ether into the inlet manifold to start combustion. Saab marine engines, Field Marshall tractors (among others) used slow-burning solid-fuel 'cigarettes' which were fitted into the cylinder head as a primitive glow plug. Lucas developed the 'Thermostart', where an electrical heating element was combined with a small fuel valve. Diesel fuel slowly dripped from the valve onto the hot element and ignited. The flame heated the inlet manifold and when the engine was turned over the flame was drawn into the combustion chamber to start combustion. International Harvester developed a WD-40 tractor in the 1930s that had a 7-liter 4-cylinder engine which ran as a diesel, but was started as a gasoline engine. The cylinder head had valves which opened for a portion of the compression stroke to reduce the effective compression ratio, and a magneto produced the spark. An automatic ratchet system automatically disengaged the ignition system and closed the valves once the engine had run for 30 seconds. The operator then switched off the gasoline fuel system and opened the throttle on the diesel injection system. Recently direct-injection systems advanced to the extent that prechambers systems were not needed using a common rail with electronic fuel injection. [edit] Gelling Diesel fuel is also prone to "waxing" or "gelling" in cold weather, terms for the solidification of diesel oil into a partially crystalline state. The crystals build up in the fuel line (especially in fuel filters), eventually starving the engine of fuel and causing it to stop running. Low-output electric heaters in fuel tanks and around fuel lines are used to solve this problem. Also, most engines have a "spill return" system, by which any excess fuel from the injector pump and injectors is returned to the fuel tank. Once the engine has warmed, returning warm fuel prevents waxing in the tank. Due to improvements in fuel technology, with additives waxing rarely occurs in all but the coldest weather when a mix of diesel and kerosene should be used to run a vehicle. [edit] Fuel delivery A vital component of all diesel engines is a mechanical or electronic governor which regulates the idling speed and maximum speed of the engine by controlling the rate of fuel delivery. Unlike Otto-cycle engines, incoming air is not throttled and a diesel engine without a governor can not have a stable idling speed and can easily overspeed, resulting in its destruction. Mechanically governed fuel injection systems are driven by the engine's gear train. [12] These systems use a combination of springs and weights to control fuel delivery relative to both load and speed. [12] Modern, electronically controlled diesel engines control fuel delivery by use of an electronic control module (ECM) or electronic control unit (ECU). The ECM/ECU receives an engine speed signal, as well as other operating parameters such as intake manifold pressure and fuel temperature, from a sensor and controls the amount of fuel and start of injection timing through actuators to maximize power and efficiency and minimize emissions. Controlling the timing of the start of injection of fuel into the cylinder is a key to minimizing emissions, and maximizing fuel economy (efficiency), of the engine. The timing is measured in degrees of crank angle of the piston before top dead center. For example, if the ECM/ECU initiates fuel injection when the piston is 10 degrees before TDC, the start of injection, or timing, is said to be 10° BTDC. Optimal timing will depend on the engine design as well as its speed and load. Advancing the start of injection (injecting before the piston reaches TDC) results in higher in-cylinder pressure and temperature, and higher efficiency, but also results in elevated engine noise and increased oxides of nitrogen (NOx) emissions due to higher combustion temperatures. Delaying start of injection causes incomplete combustion, reduced fuel efficiency and an increase in exhaust smoke, containing a considerable amount of particulate matter and unburned hydrocarbons . [edit] Major advantages Diesel engines have several advantages over other internal combustion engines. * They burn less fuel than a gasoline engine performing the same work, due to the engine's high efficiency and diesel fuel's higher energy density than gasoline..[1] * They have no high-tension electrical ignition system to attend to, resulting in high reliability and easy adaptation to damp environments. * They can deliver much more of their rated power on a continuous basis than a gasoline engine. * The life of a diesel engine is generally about twice as long as that of a gasoline engine [13] due to the increased strength of parts used, also because diesel fuel has better lubrication properties than gasoline. * Diesel fuel is considered safer than gasoline in many applications. Although diesel fuel will burn in open air using a wick, it will not explode and does not release a large amount of flammable vapour. * For any given partial load the fuel efficiency (kg burned per kWh produced) of a diesel engine remains nearly constant, as opposed to gasoline and turbine engines which use proportionally more fuel with partial power outputs. [14][15][16][17] * They generate less waste heat (btu) in cooling and exhaust.[1] * With a diesel, boost pressure is essentially unlimited. * The carbon monoxide content of the exhaust is minimal, therefore diesel engines are used in underground mines.[18] Besides,why are you parking close to a hazmat scene?curious
  17. so why not team up cummins with allision transmission? I agree with what youve said. what about the gmc topkick?lmao
  18. The powerjoke,I mean the powerstroke diesel that ford puts out is one of the worst diesel engines in the industry. The only bonus it has really is that the parts for it are stupid cheap. The only thing I will give ford is they make one rugged ass frame,everything else is garbage. GMC has put out reliable trucks despite what people think,say or how they are looking like they are going down from the economy. Duramax 6.6L diesel puts out the most torque and its a reliable motor. 80% of our city services use GMC trucks exluding ambulance service, I think they have some sort of retarded contract. Anyways, I don't like ford,and I don't think we should be putting them on the road,thats more of a risk then a benefit to patients and providers. Or maybe we should use dodge,they are reliable LOL anything but FORD.........lol all in all.....
  19. Yes, to the respected agencies. I have a big concern for people who go into countries and utilize health care programs when they are not citizens, or are fresh off the boat so to speak and able to access the same services I can, yet I am a citizen for life, I pay my taxes I work a regular hour'd job. On the same token,has health care ever been free? In the history of health care? Should it cost you money to be healthy? To get immunizations,annual check ups,clinic visits,specialist visits,a ride in an ambulance or whatever it may be? Neither of these things are free,they are either covered by green shield,blue cross or whatever your health plan is FOR CITIZENS. I probably sound like a blue collared asshole,but that's how I roll.... haha
  20. never took the time to watch the video,but i have a sneaking suspicion whatever it is,or what people say is "brutality" is probably well deserved. chances are, if the cops are beating your ass you deserve it. I dont know any cops who randomly just beat people up and hide behind the badge,in all sincerity.
  21. It all boils down to,professionalism of course. :roll:
