Weighing inThe light-rescue truck will not work for everyone depending on how much equipment is going to be carried. A complete inventory of all equipment should be done with dimensions and weights. A great tool to help you with your inventory is available from the Fire Apparatus Manufacturer''s Association Web site at www.fama.org, where you can download the Equipment Weight and Cube Calculator.Even though the GVWRs of light-duty rescues are higher than they used to be, it''s still very easy to overload the vehicle. The 2003 edition of NFPA 1901 tells us the equipment allowance for a special service fire apparatus from 10,000 to 15,000 GVWR is 2,000 pounds, and 15,001 to 20,000 pounds is 2,500 pounds. Another important consideration when determining your total weight load is your personnel. Unequipped personnel weight should be calculated at 200 pounds per person.

The author then takes the first of a number of ruminative breathers, speculating on the button. The Romans used buttons only as ornaments and even the ancient Chinese never progressed beyond the toggle and loop. Unlike the handsaw, which was refined over time, the button and its buttonhole simply appeared in northern Europe in the thirteenth century--true works of an anonymous inventive genius. Then we proceed to an influential treatise on ingenious machines published in 1588 by Agostino Ramelli, a military engineer. Among the machines is a bookstand that revolves like a Ferris wheel, holding eight books foreignautopartsisuzutrooperheatercore at a constant angle by means of a gearing system used in astronomical clocks. foreignautopartsisuzutrooperheatercore The author comments: "Of course, gravity would have done the job equally well (as it does in a Ferris wheel), but the gearing system allowed Ramelli to demonstrate his considerable skill as a mathematician." Then the author writes: "This splendid folly distracts me-I''m supposed to be looking for screwdrivers."

Odds and endsDoes your company ever install underground, insulated hot or super-chilled water lines? Then you know the process: Dig a trench and put crews of men to work long hours assembling steel pipe with foam insulation filling a steel jacket, which eventually becomes clogged and corroded with age. There is a better way.A company called Ecoflex now has pre-assembled and insulated lengths of single and dual-pipe runs -- as long as 650 ft. -- that can be laid quickly by a minimal crew. Cross-linked polyethylene pipe is available in sizes to 4 in. and all surfaces are smooth as well as non-corrodable, and the insulation doesn''t absorb water.
