Chlorine
Chlorine is a powerful oxidant and is used in bleaching and disinfectants. As a common disinfectant, chlorine compounds are used in swimming pools to keep them clean and sanitary. In the upper atmosphere, chlorine-containing molecules have been implicated in the destruction of the ozone layer.
Biogas/Greenhouse Gas, Green Fuels
This is a term for the gases evolved from decomposition of organic material, as in landfills or sewage treatment. Dominant products are CO2 and methane, accompanied by H2S. Greenhouse gases. This term applies to all the gases that potentially can modify the upper atmosphere, tending to retain the heat from the earth that is normally […]
Carbon Dioxide
While CO2 is not toxic in the same sense as CO, it has wide ranging significance to the lives of all of us, in our life processes and as a prime source of global warning. It is used in industries of all kinds, and we supply monitors using the infrared principle for concentrations ranging from […]
Carbon Monoxide
This toxic gas is a key to our business at KWJ. Our oldest and most-numerous product is a continuous monitor for compressed air, to indicate and alarm if the CO content goes above 10 ppm, a recognized limit for supplied air breathing purposes. And CO is the objective of the PocketCO, our innovative personal monitor. […]
Hydrogen Sulfide
Probably the best-recognized toxic gas, with its rotten-eggs smell and its presence wherever organic decomposition is occurring. It is toxic in small quantities, with an allowable level of only 10 ppm. But it is detected by smell at far lower levels. The treacherous characteristic is that the sense of smell soon gets degraded to the […]
Hydrogen
The simplest, lightest gas, which in burning combines with oxygen to produce only water and heat, so is an ideal fuel gas. But its production and handling entail many problems. It has the highest thermal conductivity of any gas, so can be used for cooling purposes in rotary elecrical generators. It is detected by catalytic […]
Freon
Freon is DuPont’s trade name for its odorless, colorless, nonflammable, and noncorrosive chlorofluorocarbon and hydrochlorofluorocarbon refrigerants, which are used in air conditioning and refrigeration systems. Freon was initially developed in the early 20th century as an alternative to the toxic gases that were previously used as refrigerants, such as ammonia, chloromethane, and sulfur dioxide.
Methane/Natural Gas/Propane
These gases are commonly used to heat our homes, and cook our food. As combustible gases though, they can be dangerous if they are allowed to build up in an enclosed area where a spark might ignite them. In addition, these gases can displace oxygen in the air, resulting in asphyxiation.
Nitrogen
Nitrogen composes approximately 78% of the air we breath. Rapid release of nitrogen gas into an enclosed space can displace oxygen, and therefore represents an asphyxiation hazard. This may happen with few warning symptoms, since the human carotid body is a relatively slow and a poor low-oxygen (hypoxia) sensing system. When inhaled at high partial […]
Oxygen
Oxygen constitutes 20.9% of the volume of air, and is the component of air that is essential for our respiration process. Low-levels can cause health problems, and O2 at a high partial pressure can be toxic. Further, high-concentrations of O2 can promote rapid combustion.
Hydrocarbons
A hydrocarbon is an organic compound consisting entirely of hydrogen and carbon. The majority of hydrocarbons found naturally occur in crude oil, and make for one of the Earth’s most important energy resources. The predominant use of hydrocarbons is as a combustible fuel source.
Nitrogen Dioxide
Nitrogen dioxide is toxic by inhalation. Symptoms of poisoning (lung edema) tend to appear several hours after one has inhaled a low but potentially fatal dose. Also, low concentrations (4 ppm) will anesthetize the nose, thus creating a potential for overexposure. Nitrogen dioxide is formed in most combustion processes using air as the oxidant. The […]
