The SKC 526-100 Indoor Air Formaldehyde Passive Sampler is the only sampling device designed for accurate, cost-effective indoor measurements of low formaldehyde levels in the home, office, or industrial environments over a 5 to 7 day period.
Field validated upon NIOSH Method 3500 by the Indoor Air Quality Program of Berkeley Laboratories, it's the first of its kind requiring no special equipment or trained personnel for sampling, nor liquid reagents. There are no known interferences to the formaldehyde passive sampler, thus formaldehyde may be accurately measured in the presence of other substances such as phenol, aldehydes, and aromatic hydrocarbons.
How to Use
Formaldehyde is commonly found 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 and 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, nose, and throat; excessive thirst; headache; sneezing; shortness of breath; excessive phlegm and dermatitis. Formaldehyde has also demonstrated mutagenic properties, and it can react with hydrogen chloride to form bis-chloromethyl ether (BCME), a potent carcinogen.
Formaldehyde Exposure Standards
On December 4, 1987, the U.S. Department of Labor, Occupational Safety and Health Administration (OSHA) issued a comprehensive regulation covering occupational exposure to formaldehyde at 29 CFR 1910.1048. This rule reduced the permissible exposure limits (PELs) to 0.75 part formaldehyde per million parts of air (ppm) as an 8-hour time-weighted average (TWA), and established a 2 ppm 15-minute short term exposure limit (STEL).
The comprehensive standard also included an "action level" of 0.5 ppm, measured as an 8-hour TWA, and provisions for employee formaldehyde exposure monitoring, medical surveillance, recordkeeping, emergency procedures, preferred methods to control formaldehyde exposure, selection of personal protective equipment, & hazard communication. OSHA's ruling was based upon consideration of new evidence including animal bioassays and epidemiological evidence, and the recognition of formaldehyde as a potential occupational carcinogen and its irritating and sensitizing effects.
