    I would readily help someone to came to me for help in the station, versus someone who was given an assignment to research these answers, and instead asks for forum members to answer the questions for him. He even admits it...

    Part of pasing the test is proving that you can find the answers yourself
    My wise and profound comments and opinions are mine alone and are in no way associated with any other individual or group.

    Rescue rope must be dynamic, meaning it will stretch somewhat under a load and absorb shock. Utility rope is static, meaning it will not stretch under a load. Also the composition of the rope differs. And yes, used rescue rope can be used as utility rope.

    What do Fire Investigators Carry? My dept, coffee, donuts, and a can of chew. I don't know what they are looking for.. a camera maybe?

    Epic Fail sir. Don't know if you are leading this guy astray just to mess with him, or if you honestly believe this.

    Most life safety rope, or rope used in a rescue operation will be static kern-mantle. Dynamic rope is used primarily by the rock climbing community. Due to it's elastic nature it has been deemed by most spec ops to be difficult to work with in rescue situations.

    You don't want to fall or absorb a shock with rescuing someone, littering a patient, or picking someone off. Imagine creating a high-line with that much sag in the line, wouldn't be practical and you'd probably get stuck in the middle.

    The argument can be made for Dynamic during very specific rescue situations, but I believe you will find that most places will be able to use static in those very situations that would justify having a dynamic bag.

    I can appreciate if you are messing with the OP, as he should look this information up rather than try to get the info off of a forum (basic information at that)

    heat202: Fuel Ratio refers to the ratio of fuel (gasoline) to lubricant (petroleum or synthetic oils) that are used to power two cycle engines that are not "Oil Injected". At a ratio of 50 : 1 the usual blend is 2.5 oz of lubricant to 1 gallon of fuel. Lubricants used are specially formulated NOT to cause "carbon bridging" of the gap in the spark plug thus shorting out the plug and shutting down the engine. The higher ratios (50:1) suggest synthetic lubricant (like Optimol) while the lower ratios (32:1, 25:1) suggest petroleum based oils. The air and fuel mixture leaving the carburator passes through a "flutter valve" that closes due to crankcase pressure when the piston is in the power stroke. Partway through the powerstroke, the exhaust valve is opened and exhaust gasses are vented from the cylinder. This allows the slightly compressed fuel/air mixture in the crankcase to be forced into the cylinder, flushing the burned gasses out the exhaust valve. Slightly after the bottom of the power/exhaust stroke, both intake and exhaust valves are closed causing the fresh fuel/air mixture to be compressed and readied for ignition at the top of the stroke. It also creates a slightly negative pressure in the crankcase drawing in a fresh fuel and air supply. The heated surfaces in the crankcase, vaporize the gasoline portion of the mixture leaving behind the lubricant on bearing and piston sleeve surfaces thus providing lubrication to critical engine parts. This is probably more than you wanted to know, but it points out theneed to follow manufacturers recommendations concerning the type and amount of lubricant needed in the "Fuel Ratio".

    No to both here. Rescue rope can be used continuously unless; it takes a shock load, gets damaged or past your department's service life. Be sure to inspect and clean as needed after each use.

    Static kernmantle rope is used for most rescue situations, not dynamic rope. Dynamic rope is used sometimes if you are expecting a fall... like tower or rock climbing.
