Various gas monitors are available for use in parking structure applications. The specifics of the design determine what type of monitor or monitoring system best suits the application. This detailed, easy-to- use guideline assists the design engineer in the selection of an optimal gas detection solution.
why you want to detect the presence of carbon monoxide?
- Safety: In any facility where people are working or the public and tenants may be active, there must be due diligence on the part of the owner to assure a safe breathing environment.
- Economics: To provide fresh air in a facility where vehicles are present, a pre-determined air change per hour is required. This can be expensive for a number of reasons:1) The electrical energy required to run the fans can be high.2) The fans run continuously which incurs wear and shortens motor life.
3) The frequency of required maintenance is higher for belt and lubrication services.
4) The heat loss in a garage is higher with the high volume of air changes.
- Aesthetics: In private facilities, the outside fan noise and loss of heat within the garage can affect tenant satisfaction.
Carbon monoxide toxicity levels and related health symptoms
- Carbon monoxide poisoning is a form ofasphyxiation. Carbon monoxide combines withhemoglobin, the oxygen-carrying constituent of blood, 210 times more readily than does oxygen. Carboxyhemoglobin is then formed. Carbon monoxide lowers the oxygen carrying capacity of blood and interferes with necessary gaseous exchange functions.
- Human health effects can vary significantly based on overall state of health, sex, age and weight.
- Many studies have shown that the CO content in exhaust gases of individual vehicles varies greatly. This variation is caused by such factors as the age of the vehicle, carburetor adjustment or injector condition, quality of fuel, engine horsepower, level of maintenance, and differing driving habits of motorists.
- Levels of carbon monoxide in garages vary depending on:1) Number of cars running2) Length of travel and operation time of cars in the garage
3) Emission rate of vehicle
4) Acceptable contaminant level within a given facility
