Which disinfection method is specified for SCBA cleaning?

• A. 1 ml bleach to 1 liter water at 100°F
• B. 5 ml bleach to 1 liter water at 60°F
• C. Soap and water only, no solution
• D. Ammonia-based solution

Answer: (A)

Disinfection of SCBA components relies on a mild, properly diluted chlorine bleach solution applied at a warm temperature to kill microbes without harming the equipment. The specified method uses a very dilute bleach mix—1 mL of household bleach in 1 liter of water—and a temperature around 100°F. That combination provides effective disinfection while staying gentle on plastics, rubber, seals, and coatings found in SCBA components. After the contact time, thoroughly rinse with clean water to remove any chlorine residues and allow the gear to air dry. Soap and water alone won’t disinfect, so they’re not sufficient for ensuring microbes are neutralized. An ammonia-based solution can damage elastomer seals and other materials, making it unsuitable for SCBA cleaning. A stronger or differently composed solution could also risk material degradation or harmful residues.
