Petzl statement on a special use of the Petzl Shunt… Context: Since 1999 Petzl has provided specific information regarding the special use of the Petzl SHUNT as a back-up device for industrial rope access. Petzl required that users must have received and mastered IRATA (Industrial Rope Access Trade Association) training or similar and must also use the Petzl SHUNT within the current “IRATA method”. Extract from the June 2009 statement: “Professional operatives who choose to use the Petzl Shunt as a rope-access and work-positioning back-up device must have received and mastered IRATA training or similar, and must use the Petzl Shunt with IRATA method. Responsibility for this remains with the employer and the user.” Analysis: In the light of incidents and accidents, indicative tests have been conducted, including — but not limited to — a workshop in March 2011 with rope-access experts present. The findings of these indicative tests demonstrate that releasing a towing cord while towing a Petzl Shunt as a back-up device is not consistently effective: – In an emergency situation, the natural human reflex is to increase the grip on the cord, therefore reducing the likelihood that the cord will be pulled from the hand. – Additionally, this natural reflex may override any conscious action to open the hand and release the cord. – Consequently, either of these hazards could result in overriding the braking function of the Petzl Shunt. Following these tests, working sessions with IRATA alerted Petzl to the fact that there has not been special training sufficient to minimize this potential risk. Testing and experience demonstrates that human response to emergency situations, even among expert users and highly trained professionals, is not completely predictable. Conclusions: Previous Petzl statements required special training for this specific use of the Petzl Shunt. The lack of any described methods or special training therefore makes these previous Petzl statements obsolete. As a measure of precaution, Petzl recommends to NOT use the Petzl Shunt, while towed by a cord, as a back-up device in rope access. This statement supersedes all previous statements and communications relating to this particular use of the Petzl Shunt.
