Formaldehyde Gas Detector


Formaldehyde gas detectorThese highly sensitive portable gas detectors use photoelectric photometry method with colorimetric detection tab. The sample drawing rate is controlled by a microprocessor. The FP-30 has a direct readout of measurement value on an LCD display and can detect the new World Health Organization level of 0.08 ppm average for 30 minutes.

Formaldehyde Exposure is becoming a higher profile and legitimate concern, as over exposure to formaldehyde may pose some real health risks.

Formaldehyde exposure in homes can be a concern, as witnessed by recent news stories about flooring materials. Formaldehyde is found to a certain extent in plywood, fiberboard, resins, glues, adhesives, finishing and textile products, and methods of production can influence the potential for outgassing from these materials after construction. Formaldehyde (HCHO) is an organic compound that may be used in the manufacturing of the products listed above. It is toxic and considered a carcinogen. Common symptoms from acute exposure include irritation of the throat, nose, eyes and skin. Upper respiratory tract irritation can potentially exacerbate asthma and other respiratory illnesses such as chronic runny nose, chronic bronchitis and obstructive lung disease.

Formaldehyde can off-gas from the materials in a home for some time. Emission rates can hold relatively steady for a number of months before they begin to decline. Newer homes and recent remodeling projects are at greater risk than older homes, as the formaldehyde will eventually dissipate. Temperature, humidity and ventilation will affect accumulation and exposure. Levels in homes can vary from 15ppb (parts per billion) or less to over 300ppb. The typical threshold for the development of acute symptoms from inhaled formaldehyde is around 800ppb. Some sensitive individuals can react to lower levels such as 100ppb. The odor threshold is around 500ppb, so residents can be at risk for exposure without being able to smell the formaldehyde.

Different agencies have different permissible levels of formaldehyde exposure for workers. These standards are typically expressed as a PPM (Parts Per Million) average over time (1ppm = 1000 ppb). PEL (Permissible Exposure Limit) and TLV-TWA (Threshold Limit Value-Time-Weighted Average) are calculated over an 8 hr. period.

Standard levels include:

Occupational Safety and Health Administration (OSHA) 750ppb, or .75ppm

American Conference of Governmental Industrial Hygienists (ACGIH) 300ppb or .30ppm

National Institute of Occupational Safety and Health (NIOSH) 16ppb or .016ppm
