Warnings And Limitations - Sperian MILLER 8172 Manuel D'utilisation

All synthetic material must be protected from
slag, hot sparks, open flames, or other heat
sources. The use of heat resistant materials is
recommended in these applications.
Never use natural materials (manila, cotton,
etc.) as part of a fall protection system.
Environmental hazards should be considered
when selecting fall protection equipment.
Equipment must not be exposed to chemicals
which may produce a harmful effect. Polyester
should be used in certain chemical or acidic
environments. Use in highly corrosive or
caustic environments dictates a more frequent
inspection and servicing program to ensure the
integrity of the device is maintained. Contact
Miller Technical Services if in doubt.

1.1 Warnings and Limitations

ROPE GRABS/WIRE ROPE GRABS
• For use by ONE person only. Maximum capacity is 310 lbs. (140.6 kg), including tools. —
DO NOT EXCEED THIS WEIGHT.
• Do not use if any part of the device appears to be damaged.
• Do not attempt to service the device or alter it in any way.
• Attach the device to appropriate vertical lifelines only.
• Use of this product is not suitable when the user is positioned on an unstable surface, fine
grain material, or particulate solids such as sand or coal.
• Maximum arrest distance: 39 in. (1m)
VERTICAL LIFELINES
• Miller vertical lifelines have a minimum tensile strength of 6,000 lbs. (27kN). [OSHA
requires a minimum tensile strength of 5,000 lbs. (22.2kN).]
• Lifelines must be kept clean.
• Never allow the lifeline to become slack or to pass under or entwine around arms, legs,
neck, or any other obstacle.
• Do not tie knots in lifelines.
• Lifelines must be attached independently of the working surface and anchored above the
user to prevent a swing fall.
• Lifeline elongation characteristics: rope stretch = 5%; wire rope stretch = 0.5%
SYSTEM
• A competent person must ensure the compatibility of all connections and that of the
system.
• Do not use the system if the device does not lock onto the lifeline or if any component in
the system does not operate properly.
• The device and lifeline should be installed and used in such a manner as to reduce the
potential for a swing fall.
• Allow sufficient clearance in the event of a free fall. For synthetic rope lifelines, add 1 ft.
(.3m) of fall clearance for each 20 feet (6m) of rope above the connection point. If a shock
absorber is used, you must also allow for an additional 3-1/2 ft. (1.06m) maximum elongation.
• System must be rigged to limit the free fall distance to 6 feet (1.8m) or less.

Do not allow equipment to come in contact
with anything that will damage it including, but
not limited to, sharp, abrasive, rough or high-
temperature surfaces, welding, heat sources,
electrical hazards, or moving machinery.
Always check for obstructions below the work
area to make sure potential fall path is clear.
Allow adequate fall clearance below the work
surface.
Never remove product labels, which include
important warnings and information for the
authorized person/user.
