VOC: The Invisible Toxic Compound in your House

Did you know that you and your loved ones could be exposed to harmful chemicals in the house? When common insecticides are sprayed around the neighborhood, they can be identified through the smell and color. However, some toxic compounds cannot be identified either by smell or color.

Several toxic compounds are present and they can harm pets too. These are called Volatile Organic Compounds or VOC. These compounds could also be present in your flooring and other parts of the house. We’re here today to help you discover the types of VOCs and their sources.

What are VOCs and their types?

VOCs are a large group of chemicals found in common household items. They do not have a look or smell, making it impossible to notice or sense. The effects that these compounds have on living beings are noticeable and experienced as a result of their toxic effects. VOCs could be present in flooring material as well. Therefore, it is necessary to read the labels before buying, although some companies do not disclose the VOC content.

Appropriate VOC standards have been identified by the U.S. Food and Drug Administration (FDA) and the U.S. Environmental Protection Agency (EPA). Regulations and testing have been defined and executed to determine the safe limits and whether or not a product is safe to use. This is to ensure proper health and protection in residential, industrial, and commercial settings.

The concentrations of Total Volatile Organic Compounds or TVOC are as follows.

• Low levels: Less than 0.3 mg/m3 

• Acceptable levels: 0.3 to 0.5 mg/m3

• Marginal levels: 0.5 to 1 mg/m3

• High levels: 1 to 3 mg/m3

VOC can have both short and long-term effects. The short-term effects include eye, nose, and throat irritation; nausea, vomiting, headache, dizziness, and worsening of asthma conditions. The severe long-term result of prolonged exposure to VOC affects the liver, kidney, and central nervous system. Cancer is also known to be associated with VOC exposure.

Places in the house where VOC is found

Here is a list of toxic chemicals found around the house but which we cannot see.

1. Benzene

Benzene is found in the carpet, paint, glue, synthetic rubber, and detergents. Its effects precipitate as a result of being inhaled, exposed to the skin, or swallowed. When buying the said products, the label on it should read fragrance-free, the “Safer Choice”, and have an EPA seal of approval.

2. Formaldehyde

Formaldehyde is found in floor lacquers. Floor lacquers work as a sealant and as a hard finish that enhances the look of wood. Formaldehyde is also present in space heaters, fuel-burning instruments and appliances, and molded plastics. Therefore, look for formaldehyde-free products in floor lacquers that nowadays are available as non-toxic. When buying plastic items, the label should read BPA-free. 

3. Acetone

Acetone is popularly found in nail polish and removers, lacquers, upholstery fabric, and paste waxes. The market does sell the same products that are free of acetone as an ingredient. So, look for the label that reads acetone-free on the product.

4. Toluene

Toluene is present in wall paints. So, once the paint is applied to the walls, open the windows to ensure proper ventilation. A better alternative is to buy paints that do not contain Toluene. Therefore, make sure to check the label.

Ways to reduce VOC exposure at home

These easy and effective methods can help save you and your loved ones from being exposed to VOC at home.

• Installation and ventilation: Stick to your manufacturer’s instructions on flooring installation and ventilation. This will enable the flooring to expand during warmer seasons. It will also significantly reduce the “off-gassing” lifespan. 

• Unpack toxic items: The products that you know produce toxic fumes from their chemicals should be placed open for a few days to weeks. Remove it from its packaging to place it in an open area, shed, or garage.

• Check and re-check: It’s good to be alert and prepared regarding the items you have at home. Check for their potential sources of VOC on the labels from time to time. Alternatively, consult with an indoor air-quality specialist. 

• Dehumidify the air: Maintain your home’s humidity up to 45%. Several VOCs off-gas in higher humidity.

• Renovate during the right season: Warmer weathers are suitable for home renovations, unlike the extreme winters. This is because it is easier to leave the house open during renovations and let toxic fumes escape from the products used.

• Products that smell-free: Many products contain fragrances but it would be best to avoid them. Use fragrance-free products to avoid being exposed to VOCs released from the perfumed-scented products.

Being extra cautious makes you a responsible individual for those around you and yourself. The more you know about VOCs and how to identify them, the better your chances of not allowing exposure.
