PortaCount Safe Use Guidance

Your personal safety is important to you, your workers, and to us.


Kenelec Scientific and TSI have collated the following resources to provide guidance on how to best protect yourself and the people you are fit testing from possible transmission of or exposure to COVID-19*.


Proper fit testing techniques can help protect respirator-wearers from breathing in something they shouldn’t. The fit test itself shouldn’t form part of what you are trying to protect them from.


Keep reading to access resources on how the PortaCount operates to prevent flow of air back into the breathing space of the person being tested, and what measures you can put in place to ensure your equipment is safe for the next fit test.


We will add to this list as more resources come to hand – any new resources will also be posted on our Business Updates page, so please check back regularly for up-to-date information or get in touch using the contact form provided if you have any questions or concerns.
