BACKGROUND
The walking surfaces of the North Scrubber Complex at Orange County Sanitation District (OC San) Plant No. 2 are made of a Fiberglass reinforced plastic (FRP) grating. An investigation revealed the grating is deteriorating and replacement is the most cost-effective way to address the safety hazards.
RELEVANT STANDARDS
* Maintain a proactive asset management program
* Commitment to safety & reducing risk in all operations
PROBLEM
UV exposure to the FRP grating and bars resulted in fraying and material degradation, weakening the structure. Fiberglass particles in the air could also become a hazard to staff when working near the North Scrubber Complex.
PROPOSED SOLUTION
Replace existing FRP grating associated with the Plant No. 2 North Scrubber Complex with new gratings materials per Specification No. S-2023-1419BD.
TIMING CONCERNS
Due to structural integrity, dust, and loose fibers, the grating presents a safety hazard to personnel that need to work in the North Scrubber Complex.
RAMIFICATIONS OF NOT TAKING ACTION
Continued breakdown of the grating and escalation of health hazards will worsen.
