offgáz

Offgáz is a term used to describe the gradual release of volatile organic compounds (VOCs) from newly manufactured products. These compounds can be present in building materials, furniture, carpets, paints, and various other consumer goods. When these products are first brought into an indoor environment, they can emit VOCs into the air. This process is known as off-gassing.

The rate and duration of off-gassing depend on several factors, including the type of material, the temperature, and the ventilation in the space. Some VOCs can have a strong odor, while others are odorless. Common VOCs that can be off-gassed include formaldehyde, benzene, and xylene.

Exposure to VOCs can lead to a range of health effects, often referred to as "sick building syndrome." Symptoms can include headaches, dizziness, nausea, eye and respiratory irritation, and allergic reactions. The severity of these effects can vary depending on the concentration of VOCs and an individual's sensitivity.

To mitigate off-gassing, it is recommended to ventilate new products and spaces thoroughly. Allowing new furniture or materials to air out in a well-ventilated area before bringing them into occupied spaces can help reduce the concentration of VOCs. Choosing products with low-VOC or no-VOC labels can also be a proactive measure. Over time, the rate of off-gassing typically decreases as the VOCs dissipate into the surrounding environment.
