restoration period so that code-required work will not
result in their damage or loss.
Complying with health and safety codes, including
seismic code requirements, in such a manner that spaces,
features, and finishes from the restoration period are
Removing toxic building materials only after thorough
testing has been conducted and only after less invasive
abatement methods have been shown to be inadequate.
Providing workers with appropriate personal protective
equipment for hazards found at the worksite.
Working with local code officials to investigate
systems, methods, or devices of equivalent or superior
effectiveness and safety to those prescribed by code
so that unnecessary alterations can be avoided.
