Update and status of the ANSI/ASSE Z117.1-2009
Standard: Safety Requirements for Confined Spaces
As secretariat of the Z117 ANSI Accredited Standards
Committee (ASC) for Confined Spaces, ASSE has continued to receive
a number of inquiries related to the ANSI/ASSE Z117.1-2009 American
National Standard titled: Safety Requirements for Confined Spaces.
During committee revision meetings regarding the 2003
version of the Z117.1 standard, the Z117 ASC reviewed current available
data and information addressing confined space incidents, and noted
that evidence suggests that the cause of death associated with confined
space entry has not changed appreciably during recent years.
According to the Z117 ASC, a review of 200 confined space fatality
cases from the U.S. Department of Labor (DOL) Occupational Safety and
Health Administration (OSHA) database occurring between 1993 and 2004
confirmed that the distribution of causes had not changed to any significant
degree. The committee also noted that approximately 65 percent of incidents
with fatalities involved atmospheric contamination and engulfment accounted
for less than 10 percent of the identified causes. However, the fatality
cases in this sampling do not represent all U.S. confined space incidents
resulting in fatalities.
The aim of the newly
revised Z117 Standard is to provide for the minimum
performance requirements necessary in developing and implementing a
comprehensive confined space program for the protection of workers.

There are usually numerous questions addressing
the newly revised ANSI/ASSE Z117.1 Standard (Confined Spaces) and how
it has been used in the past related to OSHA and the General Duty Clause. We
know this standard is used by SH&E Professionals on a consistent
basis, and this is always a common question. The link below is
to a matrix which includes a collection of examples
from 1999 to 2009. You
can also get this information from the OSHA stats page, but we put
it together in one file.
It is important to note these
are Federal OSHA examples. The standard is used and recognized
by a wide variety of public and private sector organizations and companies
at the international, national, state, and local levels. Click
