OEL Testing and Installation

The trend of using high potency compounds in drug manufacturing is increasing. This presents safety, health and environmental issues, and operator exposure levels (OELs) are becoming more and more rigorous. PSL can provide a full OEL certification programme by defining OELs for each containment system. Our containment solutions can be tested and validated to achieve guaranteed containment to nanograms level.

In conjunction with our clients, PSL generates an OEL test protocol, following industry best practice guidelines such as Risk-MaPP. PSL uses a third party industrial hygienist to monitor testing and generate a final OEL testing report. Micronized lactose is typically used as the surrogate powder.

An operator mimics the client process wearing a personal air sampler near their breathing zone. In addition air samples are taken of the background and at various relevant equipment locations. An unmarked dummy sample is used as a control check on the laboratory results. An independent analytical testing laboratory is used where lactose detection resolution is as low as two nanograms.
