Topic
Harness in lieu of guards

Question

Is it the intent of section 301.4.1, to allow for alternate methods of compliance, such as personnel tied off with a harness, when section 304.11 indicates guards "shall" be required, but are not installed.

Answer Published 07/09/2014 at 1:00 PM

No.

Commentary

The guard does not constitute a material or method of construction. It is a life safety concern for workers. While OSHA rules permit harnesses in some instances, the code does not offer this alternate.
