Inspection
1.
Shock loading should be avoided at all costs, however,
the system has been designed to have a large
strength safety margin. In the event of shock loading,
damage to the rope is likely and any rope subjected
to shock loading must be removed from service.
2.
Use only equipment included with the MSA
SuretymanRescue Utility System or MSA approved
accessories. If this warning is ignored by the end user,
the user and the users management accepts all liability.
3
. Reduction of the rope strength can result from
sharp edges, overloading, shock loading and/or
incorrect storage. Care of the rope is critical to avoid
damage to the rope which could greatly reduce
system strength.
4.
The system should be used as supplied by the
manufacturer. Only qualified individuals are to re-rig
or re-rope the MSA Suretyman Rescue Utility
System.
5.
A small force of approximately 7 % is all that is
required to hold or lower a load using the MSA
Suretyman Rescue Utility System. Should the rope
become heavily soiled this friction could increase.
A slightly soiled or wet rope should not effect the
systems function, however if the rope becomes
extremely soiled the MSA SuretymanRescue Utility
System may become inoperable. Always try to keep
the rope clean and dry to avoid any unwanted
increases in friction.
1.
The MSA Rescue Utility System shall be inspected by
the user prior to each installation, and additionally by
a competent person other than the user at intervals of
not more than one year. Inspections of the rope must
be recorded in the Inspection Checklist.
2.
When inspection reveals defects, damage, or
inadequate maintenance of any component in the
system, the component affected shall be removed from
service and undergo adequate corrective maintenance
before return to service. Removal from service may
imply that defects or damage will result in retiring and
replacing some components.
3.
Remove a unit from service if any of the components
fall into a catagory below:
markings (labels) are illegible or absent;
there is evidence of excessive wear or damage to
the rope;
there is evidence of defects or damage to hardware
elements including cracks, sharp edges, deformation,
corrosion, chemical attack, excessive heating,
alteration or excessive wear;
there is evidence of improper function, improper fit
or alteration of any mechanical component;
there are parts missing.
4.
MSA or persons or entities authorized in writing by the
manufacturer, shall make repairs to equipment. No
unauthorized repairs and/or modifications are allowed.
Procedure
1.
Inspect the system prior to use and each time the
system is moved to a new anchor location. Look for
evidence of cuts, wear, fraying, grease, oil, glue, tar,
or any other conditions which could affect the
performance of the controller or strength of the pulleys.
Inspect shrink seal and thimble on both ends of rope
for damage. If shrink seal is missing, knot may have
been tampered with.
