Carbon monoxide detector

The personal security of our citizens also benefits directly from science and technology. Our police forces are equipped with light, strong bulletproof vests made of modem synthetic materials, and fire rescue personnel wear protective clothing made from temperature-resistant polymers. The smoke detectors and carbon monoxide detectors in our homes are based on chemical processes that detect dangerous substances. Personal security is enhanced in the broadest sense by water purification and by the chemical testing procedures that assure us of clean water and food. 

Carbon monoxide detectors in all homes are highly recommended. This is a simple and inexpensive measure to avoid possible tragedy. After completing the research for this box, we immediately purchased several new CO detectors for our homes.

The 2009 edition of the IFC contains requirements for installation of residential sprinklers in all new one- and two-family dwellings and townhouses, effective from January 2011. This is a brand new requirement and is parallel to what is also required (see below) in NFPA 101 and NFPA 5000. It also contains requirements for installation of carbon monoxide detectors. 

In many areas, it is mandatory for every home to have a carbon monoxide detector, like the one shown below. If you do not have a carbon monoxide detector in your home, you can buy one at a hardware store for a modest price. It could end up saving your life. 

A carbon monoxide detector emits a sound when the level of carbon monoxide exceeds a certain limit. Find out how a carbon monoxide detector works, and where it should be placed. Present your findings as a public service announcement. 

Earlier in the chapter, you learned that poisonous carbon monoxide can form during incomplete hydrocarbon combustion. The use of carbon monoxide detectors in homes and businesses has reduced the number of deaths due to carbon monoxide poisoning. Are all carbon monoxide detectors the same Telephone your local fire department, go to a library, or search the Internet to find out about carbon monoxide detectors. 

Carbon Monoxide Pass 1050 50 mL of sample gas through a carbon monoxide detector tube at the rate specified for the tube. The indicator change corresponds to not more than 10 ppm, by volume.

Chemical sensors (i) Gases (e.g. blood oxygen electrode, carbon monoxide detector) (ii) pH and ions (e.g. pH meter, potassium-selective elecbode) and (iii) optical oximetry (e.g. pulse oximeby for non-invasive monitoring of blood oxygenation). 

How many different uses of batteries can you identify Batteries power flashlights, remote controls, calculators, hearing aids, portable CD players, heart pacemakers, smoke and carbon monoxide detectors, and video cameras, to name a few. Batteries in cars and trucks provide electric energy to start the engine and power the vehicle s many electric lights, sound system, and other accessories, even when the engine is not running.

A carbon monoxide detector reads 50 ppm at 9 a.m. and 1350 ppm at 12 p.m. This most nearly indicates that the concentration of carbon monoxide... 

Typically PPE/PS, PC/ABS, and PBT/PC blends are used in electrical applications such as lighting, meters, ballasts, electrical boxes, safety yokes on power lines, smoke and carbon monoxide detectors, etc. Important material properties for these applications include good tensile strength creep resistance high HDT... 

Carbon monoxide (CO) detectors sound an alarm when peak levels of carbon monoxide reach 100 parts per million (ppm). This level roughly corresponds to a composition of air that contains 400,000 (Jig carbon monoxide per cubic meter of air (400,000 (jLg/m ). Assuming the dimensions of a room are 18 ft X 12 ft X 8 ft, estimate the mass of carbon monoxide in the room that would register 100 ppm on a carbon monoxide detector. 

Carbon monoxide detectors are relatively inexpensive and save lives. 

Modem gas from pipelines does not cause aity problems like this, but carbon monoxide formed during imperfect combustion is still a concern. It is a good idea to have gas appliances tested regularly by a specialist. Investing in a carbon monoxide detector is not very expensive, and may make good common sense especially in rooms where babies sleep. 

This table can also serve as a crude guide to help us think about the placement of smoke detectors and carbon monoxide detectors in the home. Smoke detectors should be placed on ceihngs since, although smoke is relatively heavy in term of its constituents, it will always be very hot, which wiU always produce a relatively low density. Hot air rises is the rule of thumb in this matter. Carbon monoxide detectors, on the other hand, can be placed at any location since the CO has the same density as air. Leaking CO will likely be slightly warmer than ambient air since it is the product of some incomplete combustion but mixing and convection effects will not allow it to pool at the ceiling. CO detector manufacturers recommend eye level placement of CO detectors more to keep them away from pets and children than for any reasons related to density. 

Carbon monoxide is rarely used in the laboratory, and you are more likely to encounter risk from carbon monoxide poisoning at home. Carefully examine all potential sources of carbon monoxide to ensure that you and others are not exposed. Carbon monoxide detectors are relatively inexpensive, and, along with smoke detectors, every home that uses any gas or fuel-fired appliance should have one. 

Small wall- or ceiling-mounted carbon monoxide detectors can be useful and part of an overall home safety program. But keep in mind the following ... 

Most of today s home-use carbon monoxide detectors aren t as technologically reliable as smoke detectors, and... 

The installation and use of carbon monoxide detectors is no substitute for the proper use and maintenance of combustion devices in the home. 

If you do purchase a commercially available carbon monoxide detector, make sure that it meets Underwriters Laboratories Inc. (UL) standards. As is the case with smoke detectors, carbon monoxide detectors should be installed close to sleeping areas.
