Is there an IICRC method for handling sewage backup or toilet overflow?
The procedures for processing sewage backflows are complicated and fraught with many health hazards. As such, we cannot in good conscience recommend that this work be undertaken by consumers without specialized training and experience. It must be dealt with by a professional. The good news is that professional help is available. An IICRC-certified firm with trained water damage restoration technicians may be located through the IICRC web site, www.certifiedcleaners.org, or through the IICRC toll-free referral service by calling 800.835.4624. Procedures for processing sewage contamination are covered in the IICRC’s Water Restoration Technician and Applied Microbial Remediation Technician certification categories. Further, the IICRC S500 Standard and Reference Guide for Professional Water Damage Restoration covers Category 3 (e.g., sewage) restoration.
