White Paper VOC Abatement Guide WWW.THECMMGROUP.COM VOC Abatement Guide What does new car smell have in common with freshly baked bread? The same thing it has in common with diesel emissions, dry cleaning solution, a can of paint, and a vast majority of manufacturing emissions. All of these are the result of volatile organic compounds (VOCs), carbon-based compounds that exist as a gas in normal temperature and pressure. Many of these compounds are responsible for adverse health, economic, and environmental effects. The CMM Group, a trusted leader in Air Pollution Control Systems for manufacturers ranging from aerospace to wood finishing, has written this VOC Abatement Guide in order to educate you about volatile organic compounds, direct and indirect health and environmental effects, the role of regulators in ensuring manufacturers cut back on VOC emissions, and some of the most effective ways to remove VOCs from your manufacturing processes. What Are VOCS? VOCs are short for Volatile Organic Compounds, which in turn can be summarized as nearly any compound containing carbon that is gas at normal atmospheric temperature and pressure—excluding certain compounds like carbon monoxide, carbon dioxide, carbonic acid, metallic carbides or carbonates, and ammonium carbonate. Volatile The designation of “volatile” occurs when the chemical compound has an initial boiling point less than or equal to 250° C measured at a standard atmospheric pressure of 101.3 kPa. In turn, these compounds are broken down into three categories: • Very volatile organic compounds (VVOC): Considered volatile at a temperature ranging from <0° C to 50-100° C. • Volatile organic compounds (VOC): Become gaseous at temperatures ranging from 50-100° C to 240–260° C • Semi Volatile Organic Compounds (SVOCs): Become gaseous/volatile at temperatures ranging from 240–260° C to 380–400° C 2 Organic Organic is a relatively simple term that means “containing carbon.” Carbon is a natural building block of the world, as it is small enough to form bonds with nearly every element. For example, carbon can bond with itself in stable rings to form diamonds, can form chains, or can form compounds of varying stability. Compound Carbon binds with many different elements to form compounds. At present, there have been over 10 million organic compounds discovered and documented. Of these, more than 12,000 are considered volatile, in that vapor degrades into the air from a liquid or that the compound exists in the form of a gas at room temperature and pressure. CMM GROUP VOC Abatement Guide WWW.THECMMGROUP.COM Why Does It Matter? Dangers of VOCS The danger of VOCs is threefold, as exposure to certain VOCs can cause direct impact on human health. Additionally, VOCs can react with each other or with hazardous air pollutants in heat or sunlight to form other dangerous compounds. Finally, VOCs react with nitrogen-based oxides (NOx) in sunlight to form ground-level ozone (O3), which has its own negative effects on humans, plants, and more. Transported through air and water, VOCs can cause a broad range of health and environmental impacts. Exposure to VOCs Causes Adverse Health Effects Indoors When emitted within a building, VOCs can cause a multitude of adverse health effects (cancerous and non-cancerous). The EPA has created the Integrated Risk Information System (IRIS) to track the impact of organic and inorganic compounds on the human body. Additionally, the Occupational Safety and Health Administration (OSHA) maintains exposure limits to specific VOCs, among other chemicals, on their “Limits for Air Contaminants” regulations page. Outdoors VOCs pose additional health, economic, and environmental impacts when emitted outdoors. As they are small enough to be carried by air, these compounds can travel with weather patterns or wind to new locations, or end up in waterways and drinking wells.
