Safety Support To First Responders
First responders put their lives on the line to help others, and our team helps safeguard their protection.
Our team on contract with the National Institutes of Health (NIH) Respiratory Protection Program works with staff to test respirators and establish secure fits. Similarly, they provide these fit tests for fire department personnel on a regular basis to ensure optimum safety.
In addition, during the COVID-19 pandemic, our team provided critical support to NIH healthcare personnel by performing fit tests of their N-95 masks. When fitted correctly, N-95 masks offer the highest level of protection because of their snug fit and ability to filter out large and small particles.
