March 21, 2011, Rev 01
2.1.3 FALL ARREST
This tripod is designed and rated to support an ultimate static test load in excess of 5000 lbs, and is rated
for fall arrest with a Safety Factor of 2:1 for up to 3 users when used with a Self Retracting Lifeline (SRL)
or energy absorber with a Maximum Arrest Force (MAF) rating of 900lbs (4kN) or less.
Ensure that all other system components have a working load limit matching that of the winch. System
rating is equal to that of the lowest rated system component.
2.2 SITE CHARACTERISTICS, PHYSICAL and ENVIRONMENTAL FACTORS
Work sites have associated with them any of a number of hazards related to the site itself. These may
include, but are not limited to poisonous or explosive atmospheric conditions, poisonous or corrosive
chemical hazards, hot surfaces, electrical hazards, sharp edges, engulfment hazards, or moving
machinery.
All of these factors must be taken into consideration when selecting equipment for a given application.
3. GENERAL SYSTEM REQUIREMENTS
The Tripod is designed for use with a variety of accessories to perform many functions. There are
requirements common to all such systems that include, but are not limited to, the following.
3.1 ANCHORAGE STRENGTH
The Tripod is designed to be set up and used on a supporting surface (anchorage) capable of providing
the required anchorage strength. The standards governing different situations specify various anchorage
requirements. However, at no time shall the anchorage provide any less than the greater of:
-a 2:1 safety factor on the total maximum arrest force (MAF) rating of any fall arrest system(s) being used,
-a 4:1 safety factor on personnel working loads applied to the system,
-a 4:1 safety factor on material handling loads applied to the system.
All installations MUST BE used under the supervision of a Competent Person.
3.2 COMPATABILITY OF CONNECTORS
Connectors used to connect components in the system must be compatible with each other to ensure
sufficient strength and eliminate the risk of accidental disengagement or rollout during use. Connectors
supplied with products designed, manufactured, and/or approved by Tuff Built Products Inc. will meet all
applicable requirements for connectors. Any connectors not supplied by Tuff Built Products Inc. MUST
BE selected and approved by a Qualified Person.
3.3 FULL BODY HARNESS
Use only a full body harness designed, tested, and approved for fall arrest when connecting a person to
this winch. Body belts or straps do not provide adequate support to the body to prevent serious injury or
death in the event of a fall.
