Electric wiltondrillpress pressure washers deliver 1,300 to 1,400 psi, require about 1-1/2 gpm and are the best choice for light-duty cleaning like washing cars (Photo 3), outdoor grills and garage floors (Photo 4). They generally cost less than $200 and are quieter, lighter in weight and more portable than gas-powered washers. Many have built-in tanks for optional detergent use. Always connect electric washers to power outlets that are protected by a ground fault circuit interrupter (GFCI) and use only 12- or 14-gauge extension cords.

Model 71773 concrete chain saw cuts reinforced concrete, brick, block, concrete pipe, etc., up to 14 in. deep, in one pass. Powerful and portable, it quickly cuts mechanical openings, irregular shapes, and square comers. Saw can be hand-held or used with the optional SpeedHook guide to make straight cuts through walls and other surfaces. A rugged air-powered saw and flexible track system that mounts onto vessels, tanks and any other flat or curved surface to assure perfectly square cuts is available. The APS-138 Air Powered Saw features a mounting trolley that glides along the FLEX-track, a flexible tracking system, which attaches securely by tack welds onto any size vessel or tank requiring service. Eliminating the use of torches, this saw and track produces cuts with [+ or -] 1/8 in. accuracy and is a suitable system for cutting window sections out of a vessel. Suitable for cutting stainless steel, inconel, aluminum, and carbon steels up to 4 in. thick, the APS-438 has a 3 HP motor, can be supplied with reinforced fiberglass, or abrasive cutting blades, and rigidly fits onto the track by flour ''V'' grooved wheels on the mounting trolley. After cutting, no further rework is needed and the track is reusable. This air mini-saw is a compact, light-weight (1.8 lb.) reciprocating saw that works in limited clearance areas. It produces 500 strokes per minute and is able to cut through mild steel, aluminum, plastic, fiberglass and wood. It features a lock-on mechanism for continuous applications. Sears Industrial. Arborists and landscape maintenance people now have a power pole saw available whose engine meets California''s stringent GARB II as well as EPA standards without the need for a catalytic wiltondrillpress converter. The PSZ2500S is powered by RedMax''s 25.4cc StratoCharged two-cycle engine, which meets clean air standards by introducing fresh air into the wiltondrillpress engine between the exhaust gases and the fresh charge of air/fuel mix.

Now, a relatively new technology shows promise of adding an element of certainty to an otherwise uncertain rescue.Downed firefightersOrange County (Fla.) Fire and Rescue has completed initial field tests of a Global Positioning System - based rapid-deployment, in-building personnel geo-location and tracking system for use by firefighters on the fireground. The system is designed by MeshNetworks of Maitland, Fla., a mobile broadband networking firm, with systems integration assistance from IBM.This Mesh Enable Architecture system, a spin-off of the company''s sophisticated military battlefield geo-location solution, employs three or four routers mounted on 6-foot tripods positioned around the burning building. Once the routers obtain their exact latitude and longitude via GPS, they are able to perform wireless radio triangulation to fix the location of any firefighter within the perimeter who''s equipped with a cell phone - sized transponder device.
