Description


The ChromAir badge is a patented direct-read colorimetric device to indicate the presence of mercury at relevant exposure doses. The badge is constructed from five cells attached on one side to a colorimetric sensor and on the other side to a series of different diffusive resistances. Mercury vapor diffuses through the different diffusive resistances and reacts with the sensor, producing color change from white to purple. The color produced on the sensor is a direct measure of the exposure dose. Observe the formation of the threshold color on the individual cell and read the corresponding exposure dose.

Mercury is a silver-white, heavy, mobile, liquid metal with no specific odor. It is readily absorbed through the skin, the gastrointestinal tract and the respiratory tract. Chronic exposure may cause inflammation of the mouth and gums, kidney damage, muscle tremors, depression and nervousness. Mercury spills and heated mercury are particularly hazardous. OSHA PEL (permissible exposure limit) in the general industry for mercury is 1 mg/10 m3(TWA). NIOSH REL (recommended exposure limit) for mercury is 0.05 mg/m3(TWA). Mercury is used in barometers, thermometers, hydrometers, pyrometers, and in mercury arc lamps producing ultraviolet rays. It is also used in pharmaceuticals, agricultural chemicals and antifouling paints.

Instructions

  1. Allow the badge to warm to room temperature prior to removing the badge from its protective pouch.
  2. Enter all pertinent information on the label before monitoring is started (i.e. name, location, date and start time).
  3. Prior to exposure, remove the protective strip from the first cell on the front of the badge.
  4. For personnel monitoring, attach the badge near the user’s breathing zone (i.e. collar) with the front side exposed to the surrounding atmosphere.
  5. For area monitoring, attach the badge to a stand and mount in a centralized area with the front side exposed to the surrounding atmosphere.heck the back side of the badge periodically to determine the exposure dose (mg/m3•hr).
  6. To read the monitor, locate the highest level cell with threshold color.
  7. To obtain the average concentration (mg/m3), divide the exposure dose (mg/m3•hr) by the exposure time in hours.

Example: If the sampling time is 2 hours and the badge reads 0.5 mg/m3•hr, the average concentration is determined by: 0.5 mg/m3•hr Therefore the average concentration is 0.25 mg/m3. 2hr
