How often should contaminated arc proof be removed when asbestos is present?

• A. Every 1 foot
• B. Every 3 feet
• C. Every 5 feet
• D. Once per shift

Answer: (B)

In areas where asbestos is present, you keep contamination contained by refreshing the contaminated arc-proof at regular, short intervals as you move along the work area. Removing and replacing the contaminated arc-proof every three feet creates a fresh barrier, helping prevent asbestos fibers from drifting into clean zones and making subsequent cleanup easier. If you went more often, it would slow things down without adding much safety benefit; if you went less often, fibers could spread between intervals. So, the practical and safety-focused interval is every three feet.
