Can a seismic strut touch a medical gas or copper pipe

A rigid brace should not pin or rub another trade line. Stop, clear the conflict, and revise the brace angle/attachment by approved direction.

Plain-English answer

Metal-to-metal contact between a seismic brace and a high-consequence line is not acceptable field “clearance.” It can rub, wear, and damage the other system.

Hold the brace, identify the affected trade, and coordinate a revised brace angle, clamp location, anchor point, or route that keeps the brace independent of other utilities.

Ask Foreman

Our rigid seismic brace at [location] is hard against [other trade line]. I stopped tightening it. Do you want the brace angle/anchor revised and the other trade notified?
