Toxic gas exposure in buildings: gases, allowable

Effects of Toxic Gas Exposure to Ammonia, Arsine, Arsenic, Bromine, Carbon Dioxide, Carbon Monoxide, flue gases, heating equipment exhaust gases, Hydride, as well as odors smells. This document gives basic information about exposure to and potential health hazards from a number of common toxic gases that may be found indoors or in or around buildings.

Carbon monoxide - Wikipedia

2018-10-13Carbon monoxide (CO) is a colorless, odorless, and tasteless gas that is slightly less dense than air. It is toxic to hemoglobic animals (both invertebrate and vertebrate, including humans) when encountered in concentrations above about 35 ppm, although it is also produced in normal animal metabolism in low quantities, and is thought to have

Carbon monoxide is a dangerous, poisonous gas that kills hundreds of people each year and injures many more. The most common causes of carbon monoxide poisoning are poorly fitted or maintained domestic fossil-fuel-burning heating appliances, such as boilers.

How to choose a carbon monoxide detector - Which?

A good quality carbon monoxide detector will sniff out the danger and let you know when there’s carbon monoxide in the air. But there are plenty of ineffective alarms on sale – in fact, a fifth of all of the models we’ve tested were so unreliable and dangerous that we’ve labelled them Don’t Buys.

2018-10-1The choice of architecture comes down to one of utility. If the application cannot tolerate an expensive, failure-prone, power-intensive mechanical shutter, an interline device is the right choice.
