Even though a laboratory may on the surface be clinically sterile, it could still be contaminated by VOCs coming from either sources within the laboratory, neighbouring rooms or even the surrounding area. There are many different VOCs that can be found in a laboratory, including ethanol and isopropanol alcohol.

Ethanol, also called alcohol, is a clear, colourless liquid that is used as a principle ingredient in alcoholic beverages, such as beer and wine. Ethanol is a natural byproduct of plant fermentation and can be produced through the hydration of ethylene.

Because ethanol can dissolve in water and other organic compounds, it is an ingredient in a range of products, including personal care products, beauty products, household products, food additives, and fuel. Ethanol is effective in killing micro-organisms like bacteria, fungi, and viruses. Therefore, it is a common ingredient in many hand sanitisers.

Isopropyl Alcohol Concentrations Monitored In Laboratories

Isopropyl alcohol has numerous household uses, including antibacterial first aid cleanser and disinfectant applications. Industrial markets use the compound for solvents and fuel additives, while medical uses include DNA extraction, as a specimen preservative, and as a solvent. Certain care products, like hand sanitiser, contain rubbing alcohol as a primary ingredient.

Although typically non-toxic and quick evaporating, overexposure to isopropyl alcohol can cause a variety of health concerns, whether by direct skin contact or inhalation, including dizziness, nausea, and skin irritation.
