Indoor air qualityIn my IAQ articles I have long fussed and fumed over the need for companies claiming to be in this business to have testing capabilities. I came across Air Quality Sciences, which provides such services to hvac contractors. The company rents you the sampling equipment, tells you how to use it and provides accurate test results.UV light kills bacteria. Ozone kills mold and bacteria. Both have been used in IAQ remediation systems for years, and several companies displayed such wares. However, I was struck by the way these concepts were put together in a well-thought-out package from Sol Aire. Its Whole House Air Purification System combines a germicidal lamp and an ozone generator in a single device. You simply cut a hole in the plenum and insert the active elements. Integral mounting magnets hold it in place. Plug it into a standard 120V outlet. The system turns itself on and off automatically by sensing air flow. Many new IAQ test tools were on display, but the one with which I was the most impressed was TPI''s Model 705 carbon monoxide analyzer. It reads CO levels out directly in ppm. It''s fast and easy to use.

A series of accidents involving air-powered nail guns last summer brought home the fact that the productive and powerful tools are also highly dangerous and need to be handled with respect. In the most tragic case, a framing nail punctured the heart of carpenter Camillo Juandelos on a home construction site in Ocean View, Md., in July, ending the man''s life at the age of 25. Police said Camillo''s brother Jesus was holding the gun that fired the deadly nail.According to reports in the Delaware News-Journal, the accident took place as the two men were framing new homes in a development in Ocean View. Jesus had been bending over a stud wall using the air nailer, and then straightened up and turned to call his brother. But Camillo was not on the other side of the room as Jesus thought; he was already standing right behind his brother. Camillo made contact with the nose of the nail gun, triggering the bump-nail mechanism and taking the nail in his chest.

WILLIAM''s new line of screwdrivers features square handles and square shanks to prevent rollaways and deliver more twist. These tools are ideal for heavy-duty work involving tough-to-budge slotted screws and holes. The square shank provides a perfect grip for pliers or wrenches in order to deliver more torque with safety. The square-shaped handle with molded-in thumb stop creates a stronger, comfortable grip for turning difficult screws by hand. It also prevents the screwdriver from rolling away when laid down. Rounded corners, a textured surface, and a resilient feel make the handle comfortable to the hand. Chrome blades resist corrosion and facilitate clean-up after the job. The drivers come in 3/16, 5/16 and 3/8 in. blades and various lengths. There''s no greater sin in gunsmithing than buggering a screw. Well, there might be, but screw-buggering is still at the top of the heap. I don''t know how I''d get along without the sets of Brownells Magna-Tip screwdrivers I use all the time. Now, Brownells has brought us some kits designed with specific guns in mind and a very handy gadget called the "Designated Driver" that will hold four -- count ''em, four -- Magna-Tip bits.
