A construction project involves removing 150 square feet of acoustic ceiling tiles installed in 1975. Testing reveals 2% asbestos content. What Cal/OSHA notification requirement applies?
Correct Answer
B) 10-day advance notification to Cal/OSHA
Cal/OSHA requires 10-day advance notification for asbestos removal projects involving more than 100 square feet of asbestos-containing material.
Why This Is the Correct Answer
Cal/OSHA requires 10-day advance notification to the agency before beginning asbestos removal work that involves more than 100 square feet of asbestos-containing material (ACM). This project involves 150 square feet at 2% asbestos content, which exceeds the 100 square foot threshold and triggers the mandatory 10-day advance notice.
Why the Other Options Are Wrong
Option A: 30-day advance notification to Cal/OSHA
30-day advance notification is not the Cal/OSHA standard. This figure may be confused with EPA NESHAP or other environmental regulations that require 10 business days (which can approximate 14 calendar days). Cal/OSHA specifically requires 10 days, not 30.
Option C: No notification required
No notification is incorrect. With 150 square feet of ACM (exceeding the 100 sq ft threshold), notification is absolutely required. Failing to notify Cal/OSHA before beginning this work would be a serious violation.
Option D: 24-hour advance notification to Cal/OSHA
24-hour advance notification is far too short for a project of this scope. A 24-hour window applies to emergency or unplanned situations under certain hazardous material regulations, not to planned asbestos abatement projects over 100 square feet.
Memory Technique
100 sq ft = notification trigger. 10 days = notice period. Both involve the number 10. Over 100 sq ft β 10-day notice to Cal/OSHA.
