Workplace Safety Grade D Breathing Air - Episode 12

What happens when the air you're breathing at work looks fine… but hasn't been properly tested? In this episode of Safety Unleashed, Drew and Chris dig into one of the most misunderstood gray areas in industrial safety: Grade D Breathing Air. They break down what "proper breathing air" really means across different applications, why testing and verification matters, and where companies get stuck between bottles, compressors, filtration, and lab results. If you've ever wondered who owns the liability, how often air should be tested, or what changes when you move a compressor on a jobsite—this episode will help you think through it with clarity (and a little humor). You'll learn how to: • When Grade D breathing air is required, and what it should be supporting on the job • The real tradeoffs between bottles and compressors, including testing and downtime • Why "tested" isn't always the same as "certified," and how that impacts responsibility • What questions to ask about filtration, CO monitoring, sampling methods, and moving equipment Proper breathing air for specific applications. Grade D is utilized for first-line break, blasting, healthcare, and more.
