1.0 PRODUCT APPLICATION
1.1
PURPOSE: 3M Winches secure to 3M Fall Arrest systems and enable these systems to be used for other applications.
3M Winches are designed for use as part of a Work Positioning or Rescue system. Figure 1 illustrates the winch models
covered by this instruction manual. Depending on the winch model, system applications may also include material
handling, personnel riding, and climbing. For more information on system applications, refer to Table 1.
;
Never use 3M Winches as primary fall arrest devices in a Fall Arrest system.
1.2
STANDARDS: Your product conforms to the national or regional standards identified on the front cover of these
instructions. If this product is resold outside the original country of destination, the re-seller must provide these
instructions in the language of the country in which the product will be used.
1.3
SUPERVISION: Use of this equipment must be supervised by a Competent Person
be supervised by a Qualified Person
1.4
TRAINING: This equipment must be installed and used by persons trained in its correct application. These instructions
are to be used as part of an employee training program as required by national, regional, or local standards. It is the
responsibility of the users and installers of this equipment to ensure they are familiar with these instructions, trained in
the correct care and use of this equipment, and are aware of the operating characteristics, application limitations, and
consequences of improper use of this equipment.
1.5
RESCUE PLAN: When using this equipment and connecting subsystems, the employer must have a written rescue plan
and the means to implement and communicate that plan to users
site rescue team is recommended. Team members should be provided with the equipment and techniques necessary
to perform a successful rescue. Training should be provided on a periodic basis to ensure rescuer proficiency. Rescuers
should be provided with these instructions. There should be visual contact or means of communication with the person
being rescued at all times during the rescue process.
1.6
FALL CLEARANCE: When determining necessary Fall Clearance for a Fall Arrest system, each component of the Fall
Arrest system should be taken into account. There must be sufficient Fall Clearance to arrest a fall before the user strikes
the ground or an obstruction. For more information on Fall Clearance calculation, refer to the manufacturer instructions
included with your connecting subsystem.
1.7
SWING FALLS: Swing Falls occur when the anchorage point is not directly above the point where a fall occurs (see
Figure 4). The force of striking an object in a swing fall may cause serious injury or death. Do not permit a swing fall if
injury could occur. Minimize swing falls by working as directly below the anchorage point as possible. The Required Fall
Clearance (FC) of the user increases as User Work Radius (W) increases, since the total fall distance will be greater than if
the user had fallen directly below the anchorage point.
1.8
AFTER A FALL: If this equipment is subjected to fall arrest or impact force, remove it from service immediately. Clearly
tag it "DO NOT USE." See Section 5 for more information.
2.0 SYSTEM REQUIREMENTS
2.1
ANCHORAGE: Anchorage requirements vary with the Fall Protection application. The mounting structure on which the
equipment is placed must meet the Anchorage specifications defined in Table 1.
2.2
CAPACITY: The user capacity of a complete Fall Protection system is limited by its lowest rated maximum capacity
component. For example, if your connecting subsystem has a capacity that is less than your harness, you must comply
with the capacity requirements of your connecting subsystem. See the manufacturer instructions for each component of
your system for capacity requirements.
2.3
ENVIRONMENTAL HAZARDS: Use of this equipment in areas with environmental hazards may require additional
precautions to prevent injury to the user or damage to the equipment. Hazards may include, but are not limited to: high
heat, chemicals, corrosive environments, high voltage power lines, explosive or toxic gases, moving machinery, sharp
edges, or overhead materials that may fall and contact the user or equipment. Contact 3M Technical Services for further
clarification.
2.4
LIFELINE HAZARDS: Ensure the lifeline is kept free from all hazards including, but not limited to: entanglement with
users, other workers, moving machinery, other surrounding objects, or impact from overhead objects that could fall onto
the lifeline or users.
2.5
SHARP EDGES: Avoid using this equipment where system components will be in contact with, or scrape against, sharp
edges and abrasive surfaces. All sharp edges and abrasive surfaces must be covered with protective material when
contact is unavoidable.
