Il problema della corrosione degli ancoraggi nelle falesie marine è purtroppo sempre presente e di attualità. Ne avevamo già parlato in altri articoli http://www.sicurezzainmontagna.net/attenzione-agli-ancoraggi-nelle-falesie-marine/
Allego di seguito un post di Maurizio Oviglia su FB che a sua volta riporta una lettera di Michel Piola su un incidente avvenuto in Sicilia (fortunatamente senza conseguenze) che riporta quanto possa essere pericolosa la situazione. Continua a leggere
Attenzione ABS segnala problemi per alcuni modelli di ABS Vario della stagione 2011/12.
“ABS RECOMMENDATION FOR RETROFITTING
We have recently received frequent indications that the airbag compartments in Vario base units from the 2011/12* production series may rip or tear when the airbags are activated. Tests have shown that during prolonged, closed storage, the Velcro fasteners sometimes develop such a large holding force that the inflating airbag tends to rupture the airbag compartment rather than tear away from the Velcro and then unfolds inside. If the the serial number starts with 612 or 712, please contact us using this contact form. Please make sure you use this form so that we can immediately send you the precisely tailored Velcro strips and instructions for free.”

Attenzione richiamo per il sistema di attivazione wireless.
“ABS recalls its Wireless Activation system. During training activations a fault has been discovered in the light detection mechanism. Therefore ABS offers its customers an upgrade of the Wireless Activation system by December 15th 2013. The self-activation mechanism of the airbags is not affected.
During training activations particular problems with the remote activation of the ABS Wireless Activation have been discovered. This remote activation system offers an additional function: Group members can activate their airbags among each other. All current ABS avalanche airbags can be optionally equipped with the Wireless Activation.
The self-activation mechanism of the airbags is not affected by the Wireless Activation system. An intensive analysis showed the following result: The photo detection in the activation handle that converts the flash of the gun powder cap into a remote signal is not able to detect major deviations due to aging processes. Those deviations only occurr in some case. To ensure their safety ABS will offer an upgrade to all customers.
ABS customers, who own a Wireless Activation unit are asked to send it including the
by December 15th 2013 to the following address:
After a comprehensive upgrade of the light detection the unit will be returned to the customer 6 weeks after inbound.
All ABS systems which are not equipped with additional Wireless Activation are not affected.
What is the Wireless Activation?
The Wireless Activation is a radio-controlled remote activation for ABS® TwinBags. If configured appropriately, a single member of the group can activate all other group members’ airbags in the event of emergency. Your own ABS® backpack can always be activated independently, regardless of this.”
