Electric blankets

After remaining stable for many years (since mid-1940s), sales of electric blankets dropped by 11 percent... 

Eighteen congressmen asked that electric blankets be labeled as hazardous for children and pregnant women. As a result, all U.S. blanket manufacturers now include warnings with their products, advising that children not be permitted to use electric blankets. 

Some appliances, such as toasters, popcorn poppers, broilers, dishwashers, refrigerators, ovens, ranges, clothes dryers, and electric blankets are, or have been, manufacmred with asbestos-containing parts or components for thermal insulation. As a typical example, hair dryers with asbestos-containing heat shields were only recalled in 1979. Laboratory tests of most hair dryers showed that asbestos fibers were released during use.

There has been some innovative technology applied by some wineries to maintain the wines in a warm condition. Several wineries have been visited where small tanks, puncheons, or barrels were covered with electric blankets to maintain an adequate temperature for the malo-lactic fermentation. Larger wineries utilize an external heat source to warm the storage tanks in which the red wine is held. Where wineries are using ammonia refrigeration systems directly in the jacketed portion of the fermentors, these systems can be used as a heat pump. The hot ammonia gas from the compressors is desuperheated and the tank jacket used as a condenser to condense this gaseous ammonia. This has proven to be a very effective means of warming a tank. 

The largest use is for binding fibrous and granulated wood into indoor composition board. Smaller uses are for wet-strength paper and permanent-crease textiles. About 4 percent of urea-formaldehyde resin is combined with alpha-cellulose to make molding powders (Table 15.18). These find use mainly in electrical parts such as switches, wall plates and receptacles, circuit breakers, electric blankets, handles and knobs. 

Watts are units of power, and wattage is the amount of power that is dissipated when energy is used. An electric clock might require 2 watts an electric blanket, 200 a toaster, 1,000 an electric clothes dryer, 4,500 and an electric water heater, 9,000. One kilowatt is the amount of electricity needed to light a 100-watt bulb for 10 hours an average home uses between 600 and 750 kilowatts of electricity a month. 

The patient is placed in a comfortable position to be maintained for over an hour without moving, covered in a warm electric blanket or a metallic survival blanket. 

Molding Powders. Urea-formaldehyde resins are compounded with alpha-cellulose cotton fiber reinforcement to produce molding powders (4 percent) for compression, transfer, and injection molding. Typical molding conditions are 127 to 182°C and 2000 to 8000 psi. They are superior to phenolics in white color, electrical resistance, and low cost, but are limited by moisture sensitivity (Table 3.13). They are used primarily in electrical wiring devices such as wall outlets, receptacles, electric blanket controls, circuit breakers, and knob handles. Smaller amounts are used in bottle caps, housewares, buttons, and sanitary ware. 

Testing of implanted pacing systems with electric blankets, razors, drills, and citizen band radios have been conducted. In these reports, older unipolar pacing systems could inhibit a single output pulse (13). A case series involving four patients of inappropriate ICD shocks due to slot machines has been reported (112). Recently, potential interaction between pacing systems and an Apple i-Pod has been reported (113). 

Patients should avoid direct exposiu-e of the BTDS application site to heating pads, electric blankets, heat lamps, saunas, hot tubs, and heated water beds, because an increase in absorption of buprenorphine may occiu-. Caution should be used when treating febrile patients as fever may increase absorption, resulting in increased plasma concentrations of buprenorphine. 

Extremely low frequency magnetic field (ELF-MF) exposures were highest for difiusion furnace operators at over 44 mG. The lowest exposed group was the microscope workers at 3.1 mG. For comparison, it was noted in the study that electric blankets at 2" produce an exposure of 30 mG and an upright vacuum cleaner at 2-3 produces an exposure of 30 mG. 

In small appliances, PPS is used for a wide range of items such as coffee warmer rings, electric blanket thermostat controls, frying pan handles, hair dryer grills, steam iron valves and toaster switches. In large domestic appliances, PPS is used for defroster plugs, dryer switches, microwave oven turntables, washer pump impellers, motor brush holders and flue collector/transition pipes.
