ENGLISH
1. FALL ARREST: Anchorages selected for personal fall arrest
systems (PFAS) shall have a strength capable of sustaining
static loads, applied in the directions permitted by the PFAS, of
at least; (A) 3,600 lbs. (16kN) when certication exists (see ANSI
Z359.1 for certication denition), or (B) 5,000 lbs. (22kN) in the
absence of certication. When more than one PFAS is attached
to an anchorage, the anchorage strengths set forth in (A) and
(B) above shall be multiplied by the number of personal fall
arrest systems attached to the anchorage. Per OSHA 1926.500
and 1910.66; Anchorages used for attachment of PFAS shall
be independent of any anchorage being used to support or
suspend platforms, and capable of supporting at least 5,000 lbs.
(22kN) per user attached, or be designed, installed, and used as
part of a complete PFAS which maintains a safety factory of at
least two, and is supervised by a qualied person.
2. RESTRAINT: Roof anchors installed for restraint applications
must be attached to a roof member capable of sustaining a static
load of at least 3,000 lbs. applied in any direction permitted by
the restraint system when in use. Each roof anchor installation
must be independently capable of sustaining this load.
Warning:
Restraint anchorages may only be used where there is no possible
vertical free fall. Restraint anchorages do not have sufficient
strength for fall arrest. Do not connect personal fall arrest systems
to restraint anchorages.
c. Lifelines
Werner Co. rope grabs are to be used with Werner Co. lifelines and
lifeline subsystems.
1. SIZE: This device is designed to be used on 5/8-inch (16mm)
diameter lifeline. Undersized rope may not allow the rope grab
to lock properly and may cause excessive stopping distances.
Oversized rope may impede rope grab mobility on the lifeline.
It is recommended that lifeline diameter be 5/8 inch, ±1/32 inch
(0.8mm).
2. CONSTRUCTION: Three-strand lay rope constructions are
recommended, but other constructions may also be acceptable.
Consult Werner Co. if you are considering using this equipment
with other lifeline constructions. Braided, double braided, hollow
