Re: Lead Primed Structural Steel

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Charlie Canitz,

The OSHA Lead in Construction standard 29 CFR 1926.62 provides specific
requirements for the protection of workers when disturbing
paint, including welding and burning.  Engineering controls will likely
needed (e.g., removing the paint in advance).  Paint removal can be
accomplished using mechanical methods such as vacuum-shrouded power
or less "dust-producing" methods such as chemical stripping.  If you
specific assistance, you can contact me off-line at ktrimber(--nospam--at)
