WHY DUCTLESS LABORATORY HOOD ORGANIC SOLVENT CARBON FILTERS MUST BE REPLACED ON TIME ?
Airborne organic solvents can have toxicological effects on human health. The severity of these effects depends on the concentration and duration of exposure, as well as the individual's susceptibility and pre-existing health conditions.
The most common route of exposure to airborne organic solvents is through inhalation. When inhaled, organic solvents can cause irritation to the respiratory tract, leading to coughing, shortness of breath, and chest pain. Prolonged exposure may result in chronic bronchitis, asthma, and other respiratory disorders.
Organic solvents can also affect the central nervous system, causing headaches, dizziness, confusion, and even seizures. These compounds have been linked to long-term neurological effects, such as cognitive impairment and dementia.
Exposure to organic solvents can also cause skin and eye irritation, and may even result in rashes, blisters, and chemical burns. Long-term exposure to certain organic solvents, such as benzene or trichloroethylene, have been associated with an increased risk of cancer.
Organic solvents can dissolve other substances to form a solution. They are widely used in the manufacturing process of many industrial products such as paints, inks, coatings, adhesives, and cleaning agents. Organic solvents have certain physical properties that make them useful in various applications, including high vapor pressure, low flash points, and high evaporation rates.
Vapor pressure refers to the pressure exerted by a liquid's vapor when it is in equilibrium with its own liquid phase. Organic solvents have a high vapor pressure, meaning that they evaporate quickly and easily. This makes them useful for applications where fast drying times are necessary or where the solvent needs to be removed quickly.
Flash point refers to the lowest temperature at which a liquid can produce vapors that ignite when exposed to an ignition source. Organic solvents have a low flash point, making them highly flammable and requiring special handling and storage procedures to prevent accidental ignitions and fires.
Evaporation rate refers to the speed at which a liquid changes into a vapor. Organic solvents have a high evaporation rate due to their low boiling points, which enables them to quickly evaporate and leave behind a dry surface. This property makes them useful in applications such as degreasing or cleaning, where residues are undesirable.
The physical properties of organic solvents such as high vapor pressure, low flash points, and high evaporation rates make them useful in many industrial applications. However it’s property to easily become suspended makes it’s a high risk occupational airborne hazard.
Airborne organic solvents can cause a range of toxicological effects that can affect human health over both the short and long term. It is important to take appropriate measures to minimize exposure to these compounds, such as using protective clothing and equipment, proper ventilation, and following safe work practices.
The above risky scenario will apply to chimney emission of organic solvent LEV systems. In the event the adsorption column expiry and poor efflux velocity discharge, DOWN WASH will be imminent causing increase of ground level concentration possibly to a significant risk level.
