Formaldehyde Passive Sampler
|
| Detection Range | PEL 0.2 to 2 ppm STEL 0.5 to 6 ppm * |
Exposure Time | PEL 8 Hours STEL 15 Minutes |
| Precision | PEL 6.1% STEL 6.3% |
| Mean bias | Less than 1% |
| Temperature range | 15 to 26 C (59 to 78.8 F) |
| Humidity range | 20 to 80% (at 21 to 24 C) |
| Minimum Air Flow Across Surface of Sampler |
20 cm/sec |
| Interferences | None known |
| Shelf life | 1 year |
* Note: SKC STEL samplers are designed to measure the formaldehyde STEL in the U.S. of 2 ppm. These samplers do not have the sensitivity required to detect the ACGIH TLV ® Ceiling value of 0.3 ppm with a 15-minute sample.
No Technical Training Required!
- Record the date, start time, temperature, and ID number on the
badge label.
- Clip the sampler on or near the worker's collar.
- Peel the START sticker from the front of the badge, exposing
the sample opening.
- Allow the worker to wear the sampler for the full exposure period,
15 minutes for STEL and 8 hours for PEL.
- Remove the sampler from the worker.
- Peel the STOP sticker from the back of the sampler and press
it over the sample opening.
- Send the sampler to an accredited laboratory for analysis using the chromotropic acid assay method.
Formaldehyde: What Does Risk of Exposure Mean?
Formaldehyde is commonly used in pressed-wood products such as particleboard, interior-grade plywood, and fiberboard. It is also a major ingredient in urea-formaldehyde foam insulation, adhesives, dyes, inks, medicines, and embalming fluids. Formaldehyde can be released into indoor air and, over time, may accumulate to problem levels causing mild to severe health disorders in sensitive individuals.
Symptoms of formaldehyde exposure include: irritation of the eyes, ears, and throat; excessive thirst; headache; sneezing; shortness of breath; excessive phlegm; and dermatitis. Formaldehyde is an allergen and susceptible persons may become sensitized. It has also demonstrated mutagenic properties in a variety of test systems. It can react with hydrogen chloride to form bis-chloromethyl ether (BCME), a potent animal carcinogen. NIOSH recommends that formaldehyde be handled as a potential occupational carcinogen. The International Agency for Research on Cancer (IARC) has classified formaldehyde as carcinogenic. There is sufficient evidence that it causes nasopharyngeal cancer in humans.
The OSHA Action Level (AL) is 0.5 ppm (PEL) at which some action should be taken to reduce exposure to formaldehyde. Formaldehyde remonitoring must be conducted every six months if an exposure was at or above the Action Level of 0.5 ppm, and every year if exposure was at or above the STEL of 2.0 ppm. Remonitoring must also be conducted if a process change occurs and/or engineering control measures are implemented that may result in new or additional exposure to formaldehyde.
