OHD

OHD was proud to participate in the 3rd Edition of the EU CBRN CoE Academy at the United Nations Campus in Turin, Italy.

Our European Business Development Manager, Adam Marczak, represented OHD at the event, providing live demonstrations of AeroFit®, QuantiFit2™, and other OHD solutions designed to support military respiratory protection programs.

A huge thank you to the organizers for inviting us to participate. We're grateful for the opportunity to be part of this year's Academy and to share the experience alongside our partners at Recom Industriale.

Thank you as well to everyone who stopped by the booth to connect with us.

We're in Syracuse for the NYSFAC 120th Annual Conference & FIRE Expo!

Ryan Thompson is at the OHD booth this week, showcasing solutions that help fire departments strengthen their respiratory protection programs and support firefighter safety.

Stop by the booth for a demo of:
• QuantiFit2™ respirator fit testing instrument for elastomeric respirators
• AeroFit® respirator fit testing instrument for disposable and elastomeric respirators
• Gilian® air sampling pumps and calibrators
• SVANTEK noise and vibration monitoring equipment
• ION Science gas detection technology

If you're attending the conference, stop by and chat with Ryan about the challenges your department is facing and the tools available to help keep firefighters protected.

If CNP and CNC fit testing both produce a fit factor, why do the results differ?

It's a question that causes a lot of confusion and a lot of misconceptions.

In this blog, we break down how each technology works, where the differences matter, and what the research says about accuracy, consistency, and respirator fit.

Whether you're evaluating fit testing options or simply want a clearer understanding of the technologies behind your program, this article will help you separate fact from fiction.

Following a great week at AIHA Connect, we were pleased to welcome Adam Marczak, OHD’s European Business Development Manager, and Andreas Söderlund, CEO of ABT Sweden AB, to our OHD headquarters in Birmingham, Alabama.

The visit was a valuable opportunity for our team to connect in person, exchange ideas, and strengthen relationships across our global network.

We’re grateful that Adam and Andreas extended their travels to spend time with the team. It was a pleasure having them in Birmingham.

Big things ahead!

June is National Safety Month. 🦺

Led by the National Safety Council, this annual initiative serves as a reminder that safety isn't a one-time conversation. It's something we practice every day. It's the habits we build, the procedures we follow, and the responsibility we share to protect one another.

Creating safer workplaces starts with awareness, preparation, and a commitment to doing things the right way, even when no one is watching.

Here's to making safety a priority today, this month, and every day after.

Last night we had a great time hosting customers, partners, and friends at Mulate’s during AIHA Connect 2026. It was a fantastic opportunity to catch up with familiar faces, meet new people, and spend time with others who are passionate about protecting the health and safety of workers.

During the evening, our CEO, Luke Allen, shared updates on OHD's growth and how the company is evolving to better serve the occupational health and safety community. Our Regulatory and Standards Director, Stephanie Lynch, PhD, CIH, CSP, talked about the changing industrial hygiene landscape and what organizations need to be thinking about as workplace health challenges continue to evolve. Dylan Staack, our Technical Applications and Partnership Director, shared how OHD's growing portfolio of partner products is helping us become a more complete resource for occupational health and safety instrumentation.

Most of all, it was great to spend the evening with so many customers, partners, and industry friends. Thank you to everyone who joined us and helped make the event such a success.

Today is the final day of AIHA Connect. If you haven't stopped by yet, come see us at Booth 1527. We'd love to meet you!

What a great session with Stephanie Lynch, PhD, CIH, CSP at AIHA Connect!

Her presentation, Hands-On Training in Quantitative Respirator Fit Testing, generated lively discussion and questions about quantitative fit testing and respiratory protection programs.

During the session, attendees had the opportunity to participate in live fit testing demonstrations featuring OHD's QuantiFit2™ and AeroFit® respirator fit testing instruments, gaining firsthand experience with both quantitative fit testing methods.

Thank you to everyone who joined the session, asked questions, and stepped up to participate in the live demonstrations. The engagement from the audience made it a tremendous success.

Special thanks to Luke Allen and Booth Armstrong for helping bring the demonstrations to life.
