Bioquell has enabled calibration of low-level hydrogen peroxide vapour instruments at 1 ppm verified accurately against the published OSHA 1019 method. When decontaminating a room or enclosure, entry should be prohibited until the Occupational Exposure Limit (OEL), also known as Permissible Exposure Limit (PEL), has been reached so the area can then be safely released. The level is based on a time-weighted average (TWA) over 8 hours.
