Ø: Total Working Angle <br />X: Working Distance <br />Along Leading Edge <br />Y: Distance From <br />Leading Edge <br />X <br />Y <br />ø <br />X <br />Leading Edge <br />3 <br />Compatibility: When making connections with Metal Energy Absorber, eliminate all possibility of roll-out. <br />Roll-out occurs when interference between a hook and the attachment point causes the hook gate to <br />unintentionally open and release. All connections must be selected and deemed compatible with Metal <br />Energy Absorber by a Competent Person. All connector gates must be self-closing and self-locking, and <br />withstand minimum loads of 3,600 lbs. See the following for examples of compatible/incompatible <br />connections: <br />Correct Anchorage Positioning: <br />This chart details allowable working zones required <br />to reduce risk of swing falls and improper side loading. <br />ALWAYS adhere to information specified by chart. <br />Anchor Distance <br />From <br />Leading Edge (Y) <br />Working Distance <br />Along Roof Edge <br />(Either Direction) (X) <br />Working Angle <br />From <br />Perpendicular (Ø) <br />6’ <br />10’ <br />15’ <br />20’ <br />25’ <br />30’ <br />35’ <br />40’ <br />45’ <br />50’ <br />55’ <br />60’ <br />8’ <br />9’ - 9” <br />11’ - 7” <br />13’ - 3” <br />14’ - 6” <br />16’ <br />17’ - 2” <br />18’ - 3” <br />19’ - 4” <br />19’ - 10” <br />21’ - 4” <br />22’ - 3” <br />53° <br />45° <br />38° <br />33° <br />30° <br />28° <br />26° <br />24° <br />23° <br />21° <br />21° <br />21° <br />For example, if the anchorage connector is 6’ from the leading <br />edge (Y), the working distance (X) is 8’ in each direction from <br />the perpendicular, which translates to a 53° working angle. <br />Swing Falls: Prior to installation or use, make considerations for eliminating or minimizing all swing fall <br />hazards. Swing falls occur when the anchor is not directly above the location where a fall occurs. Always work <br />as close to in line with the anchor point as possible. Swing falls significantly increase the likelihood of serious <br />injury or death in the event of a fall. <br />As shown in following image, there are potential danger zones for swing falls when using a single HLL span. <br />Use multiple HLL spans to expand area of coverage. <br />Connector <br />closed and <br />locked to <br />D-ring. OK. <br />Connector <br />to integral <br />lanyard. <br />NO. <br />Two or <br />more snap <br />hooks or <br />carabiners <br />connected <br />to each <br />other. NO. <br />Two connectors <br />to same <br />D-ring. NO. <br />Connector <br />directly to <br />webbing. <br />NO. <br />Incompatible <br />or irregular <br />application, <br />which may <br />increase risk <br />of roll-out. NO.
