-Reprinted from MSA Inspection Advisory Document Dated August 6, 2008

MSA recently received a report that the attachment handle on a 20 ft. Dyna-Lock Self-Retracting Lanyard (SRL) became loose and separated from the unit. Although the user was not injured, our inspection of the nit revealed that the ends of the two screws securing the handle were not swaged (flattened) as intended by our housing/handle supplier. The swaging process prevents the screws, which are installed from the inside of the housing, from unthreading. If a handle screw unthreads to do vibration or other means, the handle could detach from the housing and cause the SRL to separate from the anchorage resulting in loss of fall protection.
As a result of this report, we inspected other SRLs that utilize the same or similar handle design and found less than 5% of the units contained handle screws that were not swaged. All of the units found with the unswaged handle screws were manufactured or last serviced between October 2007 and June 2008.
As a result of this finding, MSA requests that users receiving this Inspection Advisory immediately inspect the 20 ft. Dyna-Lock SRLs in their possession to determine if the screws securing the handle are swaged. Any units with unswaged screws (one or both) must be removed from service and returned to MSA for repair. The repair and the shipping are free of charge. Units not exhibiting this condition may remain in use.
Dyna-Lock SRL – 20 ft. models are identified with the following MSA part numbers: 506619, 506615, 10017931, 10006447, and 10017933. Although unswaged screws were only found on units manufactured or last serviced from October 2007 to June 2008, the current supplier has manufactured the housing/handle assembly for MSA since April 2005. As a precaution, this advisory is being sent to users who purchased units manufactured or last serviced from April 2005 through June 2008.
