The IAFF was recently contacted by members of an IAFF Local affiliate experiencing issues with SCBAs entering low-air alerts despite having adequate air remaining in the cylinder.
A scientific analysis identified a metallic substance on the air pack's O-Ring. After identifying the metallic substance, the Department conducted additional inspections and found metallic substances in most units. Other Locals have since identified substances in additional manufacturers’ SCBAs.
Samples were collected and sent to an independent laboratory for further analysis. Eighteen separate metals were found in the substance (Aluminum, Barium, Boron, Cadmium, Calcium, Chromium, Copper, Iron, Magnesium, Manganese, Nickel, Potassium, Silicon, Sodium, Sulfur, Titanium, Vanadium, and Zinc).
Many of these metals have been linked to neurological, gastrointestinal, or respiratory issues, may result in lung and kidney damage, and may be potentially carcinogenic.
The IAFF recommends that all SCBAs be inspected and evaluated by certified technicians. The IAFF is also working with independent researchers to study the issue further.
