The rewards of this work are tremendous, as the BSCs are used for analyzing samples that may contain drug-resistant TB, HIV, Ebola or other pathogenic agents. In this inter-connected world, ensuring the safety of the equipment provides protection to not only the laboratory workers using the cabinets, but also the rest of us sharing this planet.
Technical Challenges
The variety of biological safety cabinets in use in the countries we visited is staggering. Our mentors helped students work with BSCs manufactured in Italy, Spain, United Kingdom, Japan, Russia, and China, some of which have as many as five HEPA filters! A large portion of the equipment encountered no longer has manuals, and in some cases, the manufacturer is no longer in business. In addition, there is the complication of testing cabinets to various standards and specifications.
The variety of situations encountered is challenging to a seasoned certifier, never mind one who is newly trained. It is crucial that a person new to the field learn broad concepts that can apply in all situations – how to analyze airflow patterns, how to develop test criteria, how to decide if the BSC passes the tests when no clear specifications exist, and—most challenging of all—how to troubleshoot and repair problems.
Logistical Challenges
Logistical challenges are equally significant. In the United States, we don’t have difficulty purchasing the testing equipment, necessary parts and filters, or transporting supplies. In countries with dirt roads and small vehicles, even transporting test equipment so that it is not jarred out of calibration becomes a challenge. If filters are shipped, it’s difficult to ensure that everyone handling them along the way understands their fragile nature. If certification uncovers a part that needs replacing, determining the closest location to purchase it and finding the money for the purchase often forces the certifier to create a creative solution that can get the BSC working quicker, and within budget.
Additional Roles
We find that the certifier’s work doesn’t end with testing and perhaps “fixing” the BSC. As is often true in the United States, laboratory workers may not understand the importance of using work techniques that don’t disrupt the BSC’s airflow patterns. Therefore, in institutions without biosafety officers, certifiers need to be able to train laboratorians on how the BSC works, where it should be located, and how to use it properly. And in many cases, certifiers have to advocate to ministry of health or other officials in order to obtain funding for the certification efforts. These additional roles require teaching and communication skills that may be new for the certifiers. They also require credibility, but it’s difficult for the new certifiers to gain credibility with lab workers or officials in countries where people often don’t know that BSCs need to be tested.
We at the Eagleson Institute have enjoyed getting to know the certifiers and their various cultures, and look forward to providing additional support to them as they face challenges unimagined by U.S. certifiers. It has truly been a learning experience for us all.
