What is a typical action if a regulator experiences 'regulator freeze' during use?

• A. Remove the regulator and continue using it as is.
• B. Terminate use and move to a warmer area.
• C. Increase the regulator to thaw.
• D. Shake the regulator to warm it.

Answer: (B)

When a regulator freezes, airflow can become blocked because moisture in the regulator turns to ice. The safest course of action is to stop using the system and move to a warmer area to let the regulator thaw before attempting to use it again. Forcing thaw by increasing flow, shaking the regulator, or removing it and continuing to use the system can be dangerous and may lead to a loss of breathing air or equipment damage. After relocating to warmth and thawing, inspect the regulator and test for proper operation before resuming use.
