VOCs – volatile organic compounds (& semi-volatile). VOCs emit gases. See “do-it-yourself” at the bottom of this page.
Are you unsure about the airborne exposure levels from your workplace chemicals? Maybe exposure is in aerosol form. Or maybe fume (condensation of volatilized metal). Or maybe there’s both air and skin contact exposure.
We are skilled at anticipating, identifying, evaluating and controlling VOCs. sample for all volatile (& semi-volatile), organic compounds. Whether from raw ingredients, intermediate states, or final product, VOCs with high vapor pressures can reach high levels in air in short periods of time. Conversely, VOCs with low vapor pressures may not reach high levels for some time. However, the safe/ unsafe levels depends on the specific VOC in question and a host of other things. Sometimes VOC air testing is not necessary. Sometimes it is imperative. Federal regulations require airborne exposures to be below the PEL (permissible exposure limits) found in Table Z-1, 2 & 3).
We provide both a qualitative and, if necessary, a quantitative assessment using standard protocols outlined by NIOSH, OSHA, ACGIH, AIHA, et al. Whether you need only small assistance with your own program, an whole program, an initial screening test, or a calculation proving over-exposure is impossible, we are here to assist.
Don’t be caught off-guard, guessing, doing too much, not doing enough, or making unreasonable estimates. Call us for a free initial evaluation.
Do-it-yourself
There is a great method of determining the general levels of VOC gas exposures yourself! Read on!
First, you obtain a colorimetric direct reading charcoal tube. These are specifically designed for quick results and the good thing is they are very easy to use requiring minimal guidance. The tubes are small and thin, made of glass with special contents that react with the specific gas you are sampling for. For example, you might want to sample acetone, styrene, carbon dioxide, carbon monoxide, benzene, formaldehyde, hydrogen sulfide, MEK, ammonia, carbon tet, chlorine, amines, ethers, ethlyenes, gasoline (BTX – benzene, toluene, xylene), the list goes on (see below for a complete list). Although there are two basic kinds and manufacturers, they are similar. A small handheld pump is used and the tubes are broken on both ends and inserted into the small pump. After seconds or minutes the air entering the one side of the tube causes a reaction that colors the tube. The tube is marked so that when the reaction is finished, soon after, there is a number that represents the quantity of the contaminant your testing for. The accuracy is given on each tube but is usually about 25-35%. This makes for a great screening tool to determine if further, more involved testing is necessary.
Allow our CIH to send you a box of tubes and guide you to doing your own air testing. You will not find tubes any less than ours since we are a direct distributor.
