Volatile organic compounds (VOCs) are hazardous carbon-based compounds that evaporate easily at room temperature and are common in nature or industry. The VOC level is very high in the closed areas of the chemical facilities producing carpet, paint, cleaning materials, furnishings, glues, permanent markers, printing equipment, cosmetics and medicine. VOCs also available at  outdoor sources include emissions from the oil and gas industry, solvent usage and transportation.

There are thousands of VOC types we encounter in our daily life. The most common examples are:

  • Acetone
  • Benzene
  • Ethylene glycol
  • Formaldehyde
  • Methylene chloride
  • Perchlorethylene
  • Toluene
  • Xylene
  • 1,3-butadiene

Even with low VOC levels in the environment, prolonged breathing of this air by workers can increase the risk of health problems related to the respiratory tract. Several studies have proven that continuous exposure to VOCs has worse consequences for asthma or people who are particularly sensitive to chemicals.

Common symptoms of VOC exposure include:
Short Term :

  • Eye, nose and throat irritation
  • Headache
  • Nausea / Vomiting
  • Dizziness
  • Increased asthma symptoms

Long Term:

  • Cancer
  • Liver diseases
  • Kidney diseases
  • Nervous System Disorders

It is necessary to have a heathy work environment and monitor VOC levels in the environment to be safe. Prosense uses PID sensors that can monitor many different VOC gases and provide safety for workers.
