What is the recommended firestopping system to use for pneumatic tubing thru an existing concrete wall that is pre-approved by HCAI/OSHPD?
Royce,
As there is no listed system for this condition, our recommendation would be to request for a custom detail in the form of an Engineering Judgment (EJ) that will reflect your exact condition. Systems should be used only when they match your exact application, so this is a situation when an EJ is required. We provide hundreds--if not thousands--of details yearly for HCAI/OSHPD projects and should be able to support you once you submit your request.
Thank you,
