Construction Standards

Use the A10 standards to eliminate hazards, lower risk and protect construction and demolition workers.

Fall Prevention

Use the Z359 Fall Protection Code to prevent falls and reduce risks for those who work at height.

Note to standards users: In June 2018, American Society of Safety Engineers (ASSE) was renamed American Society of Safety Professionals (ASSP). As a result of this change, ASSE American National Standards now bear the designation ANSI/ASSP instead of ANSI/ASSE (e.g., ANSI/ASSE Z359.2 is now ANSI/ASSP Z359.2). The organization’s name change did not affect the content of those standards.
