There are many kinds of air sampling equipment. Most require calibration before and after use to be sure they are operating properly. Piston or bellows hand pump used with color-changing gas/vapor detector tubes. These are easy to use, relatively inexpensive, give short-term, direct reading area sampling results but are inaccurate plus or minus 25% or more. Hazard evaluation is currently often done by sampling. However, evaluation can be performed by observing visible contaminants, noting odors, predicting exposure from situations such as open containers or spraying operations, or from interviewing workers about their health symptoms and complaints. Industrial hygiene often has misplaced emphasis on technical sampling methods rather than good investigations into health hazards and innovative problem solving. Learn more about sampling at Industrial Hygiene Fact Sheet 13 at state.nj.us/health/surv/documents/ihfs.pdf. For a valuable and enlightening guide to how industrial hygiene can be helpful to workers in identifying, evaluating and recommending controls for health hazards on the job, read PLAYING INDUSTRIAL HYGIENE TO WIN (2011) written by Eileen Senn, MS available at nycosh.org/uploads/control_of_hazards/Playing%20IH%20To%20Win%20Winter%202011%20(2).pdf .
