A Primer on OSHA’s New Walking-Working Surfaces Rule

August 8, 2017

In November of 2016, the Occupational
Safety and Health Administration
(OSHA) issued a final rule updating
its General Industry Walking-Working
Surfaces requirements, located in 29
CFR 1910 Subpart D. The new rule
also includes a new section in the General
Industry Personal Protective Equipment
standards, 29 CFR 1910 Subpart I, which
establishes requirements for using personal
fall protection systems. These standards,
which principally affect maintenance activities,
had not been updated since 1971.
The update brings the general industry
standard much closer to those provided
in OSHA’s existing 1994 construction fall
protection standard, 29 CFR 1926 Subpart
M, allowing for much more consistency
between the two. For example, the final rule
updates the general industry scaffold standards
with a requirement that employers
comply with OSHA’s construction scaffold
standards. Some small differences remain;
fall protection still is required when employees
are exposed to a fall hazard 4 feet or
greater from a lower level for general industry
as opposed to the 6-feet fall hazard trigger
height in the construction standards.
Careful review of the new rule is encouraged.
The majority of the rule became
effective in January of 2017, with most of
the remainder becoming effective at varying
dates over the next two years. This article
focuses on the building envelope consulting
industry and highlights some of the key
items to know about in the new walkingworking
surfaces rule.
The new rule reorganizes and clarifies
the 1971 standard, and more importantly, it
provides updated requirements for surfaces
where slips, trips, and falls are common.
These can occur in all general industry
workplaces, which can include walkingworking
surfaces such as floors, stairs,
roofs, ladders, ramps, scaffolds, and elevated
walkways. Employers are responsible
for ensuring their walking-working surfaces
are regularly inspected and maintained.
Hazardous conditions must be corrected or
repaired before employees can access the
walking-working surface. This means that
building owners may need to update their
facilities or install
new fall protection
systems to ensure
these hazards are
properly addressed.
Contractors employed
to perform work at a
building should coordinate
with the building
owner to see if the
existing fall protection
systems can be used
in conjunction with
any contracted work.
Fall Protection Systems
To better understand what the walkingworking
surfaces rule addresses, it is important
to understand the different types of fall
protection systems. Fall protection systems
can be organized into two categories: passive
and active systems. Passive systems are
stationary, non-dynamic, and do not require
personal protective equipment or active participation
from the user. Examples include
properly installed guardrails or safety nets.
Active systems are dynamic and require the
use of special equipment and participation
from the user. These are commonly referred
to as personal fall protection systems.
There are two types of active systems:
fall restraint and fall arrest. In both systems,
workers wear harnesses attached to
anchors via lanyards. Fall restraint systems
use fixed-length lanyards to prevent the
user from physically being able to move
beyond an edge and possibly fall. If restraint
cannot effectively be achieved, fall arrest
systems must be employed. Fall arrest systems
use shock-absorbing lanyards to safely
arrest a user’s descent in the event of a fall
(Figure 1A). Fall arrest anchor points must
be capable of withstanding 5000 pounds in
any direction for each employee attached.
They may also be designed, installed, and
used under the supervision of a qualified
person as part of a complete personal fall
protection system that maintains a safety
factor of at least two. Because fall restraint
systems (Figure 1B) are not designed to mitigate
an actual fall, their lanyards are not
required to have shock absorbers.
Greater flexibility in determining appropriate
fall protection is provided for in the
new rule. Any employer—be it a building

owner, consultant, or contractor—with staff performing work at a building
must follow this new rule. To start the selection process, employers
have the responsibility to first identify and evaluate hazards in the workplace.
This requirement has not changed. What has changed is that once
fall hazards are identified, employers can now select from conventional
and more unconventional fall protection means. Each site will have its
own special conditions that the employer must analyze to determine the
best fall protection system. Previously, OSHA only described use of guardrails
as the means of fall protection in general industry. Although still

commonly used, guardrails are not always
the most feasible fall protection selection.
After choosing the most appropriate fall
protection method or system, the employer
also must ensure that the fall protection
equipment and systems are periodically
inspected and maintained. Requirements
and systems described by the new rule
include guardrails, personal fall protection
systems, portable ladders, fixed ladders,
ladder safety systems, safety nets, rope
descent systems, and more. OSHA’s new
rule also requires that employers train
and retrain employees as required on the
identification of hazards and the use of fall
protection equipment.
Low-Sloped R oofs
Of particular note are OSHA’s new fall
protection requirements for work performed
on low-sloped roofs (a roof with a slope
less than 4 in 12). OSHA’s new regulations
describe specific fall approach distances
and their respective fall protection options
(Figure 2).
When work is to be performed over 15
feet away from an unprotected edge, fall
protection in the form of a guardrail system,
safety net system, travel restraint system,
personal fall arrest system, or a designated
area may be provided. Designated areas
are very similar to warning line systems
described in OSHA’s construction fall protection
regulations. When work in this zone is
both temporary and infrequent, the employer
also has the option to implement and
enforce a rule requiring that employees stay
at least 15 feet from a roof edge. Provided
this rule is followed, no additional fall protection
measures are required. Infrequent
work is described by OSHA as tasks or jobs
that are “performed only on occasion, when
needed (e.g. equipment breakdown), on an
occasional basis, or at sporadic or irregular
intervals.” OSHA describes temporary work
as that for which the duration of “the task
the worker performs is brief or short.” This
includes work that would take less time to
perform than setup of a conventional fall
protection system.
Fall protection options change for work
between 6 and 15 feet from a roof edge.
Options include providing a guardrail

system, safety net system, travel restraint
system, or personal fall arrest system. For
work that is both temporary and infrequent,
a designated area identified by warning
lines may again be used.
Any work within 6 feet of the roof edge
requires fall protection in the form of a
guardrail system, safety net system, travel
restraint system, or personal fall arrest
system.
It should be noted that residential roofs
are addressed briefly in the new rule. The
same standards apply to residential roofs
as commercial roofs, but often, residential
roofs are steep-sloped (slope of 4 in 12 or
greater). Commercial roofs are typically
low-sloped. OSHA’s rule provides a few
additional options for residential roofs, but
experience has shown that with a little extra
thought, conventional fall protection systems
often still work well on steep slopes.
Ladders
Although ladders are perhaps one of
the most common access tools found on a
job site, they also remain one of the leading
causes of injury. OSHA’s new rule covers
both portable ladders and fixed ladders.
Most notably, changes were made to the
requirements for fixed ladders. Cages and
wells previously allowed by the old rules
are now being phased out. The new rule
requires the use of a ladder safety system or
personal fall arrest system for fixed ladders
greater than 24 feet. Existing ladders with
cages and wells are currently grandfathered
in through the new rule for a period of
time, but new or replacement fixed ladders
greater than 24 feet must be equipped
with a fall arrest or ladder safety system.
One example of a ladder fall arrest system
would be a self-retracting lifeline secured
to appropriate anchorage at the top of the
ladder. A ladder safety system may have a
continuous steel cable running alongside
the ladder (Figure 3). A proprietary rope
grab runs along the steel cable and grips it
in the event of a fall. Obviously, the user of
the ladder must wear an appropriate harness
in both instances to clip into each fall
protection system. By November 18, 2036,
all fixed ladders greater than 24 feet must
be equipped with a personal fall arrest or a
ladder safety system.
Rope Descent Systems
In some instances, it may be necessary
to access work using a rope descent system
(RDS). OSHA defines RDS as “a suspension
system that allows an employee to descend
in a controlled manner and, as needed,
stop at any point during the descent.”
Equipment commonly used with RDSs
includes boatswain chairs (also known as
bosun’s chairs).
Not specifically defined in OSHA’s new
rule, industrial rope access (IRA) is a method
utilizing ropes and specialized equipment
to provide access and position workers in
locations where other conventional means
of access would not be practical (Figure
4). Although the two rope methods may
seem similar, IRA requires more rigorous
training and is multi-directional, allowing
rope access technicians to move upward,
downward, and, in some cases, side to side.
A worker using an RDS can only descend.
Appearing to acknowledge this, OSHA’s
new rule specifically addresses RDSs only.
The rule’s main effects on RDSs include
limiting use of RDSs to heights of 300 feet
or less in most situations and requiring
that RDS users attach to certified anchors.
Building owners must provide permanent,
certified anchorages used with RDSs (when

RDSs are used at their facility) and ensure
they are inspected, tested, and maintained
to support the specified load (as noted earlier).
Ultimately, this means that contractors
are less responsible for determining
appropriate anchorages when using RDSs.
They are responsible for obtaining the certification
information
from building
owners before using
anchorages, and
they still must utilize
their best judgment
before tying off to an
anchor.
Inspecting,
Investigating,
or Assessing
Workplaces
What if no work
is going on yet? What
if you are simply performing
an investigation,
inspection, or
assessment? In this
case, OSHA’s new
rule provides additional
guidance. The
new rule appears to
allow an exemption
negating fall protection
requirements in
certain conditions.
These conditions are
specifically outlined
as “inspecting, investigating,
or assessing
workplace conditions
or work to be performed
prior to the
start of work or after
all work has been
completed.” However, if a fall protection
system has been installed and is available
for use at any time, workers must use it.
Always remember that once any work is
performed, an appropriate fall protection
system must be used.
Summary
Similar to other OSHA requirements,
this new rule likely will be revisited and
reconsidered as it is applied to new and
varying conditions. At the moment, each
employer, including mine, has its own interpretation
of what the many facets of this
rule mean. Undoubtedly, OSHA will issue
future Letters of Interpretation to clarify the
intent and purpose of the rule.
Whatever the new rule may say, it
is important that employers and employees
always maintain the highest level of
awareness when working in any workplace.
OSHA’s rule attempts to limit the chance for
slips, trips, and falls significantly, but no
standard can completely prevent the possibility
of workplace accidents. Conditions
can change rapidly on a job site. Appropriate
training for identification of hazards and the
use of equipment are essential for dealing
with both routine day-to-day tasks and
unexpected surprises.

be found on OSHA’s website (https://www.
