“Further to this, sudden exposure to cold water can induce the cold water shock response, which can significantly affect the individual’s ability to hold their breath.”
Indeed, a primary reason for developing the new EBS was to take into consideration the additional air capacity required by someone under extreme stress. When people panic, their breathing is rapid and air supplies can be quickly depleted.
Parkes said: “The introduction of a 310 bar cylinder allows us to substantially increase the amount of breathable air available for use by the user in a water impact scenario. By combining

composite materials within a pocket shielded and reinforced for impact protection, our design teams have also delivered a much lighter, more resilient CA-EBS.”
This new bespoke EBS is a key integrated feature of Survitec’s Halo lifejacket, launched in September last year.
Halo, the first aviation lifejacket to
utilise Fusion 3D technology, allows for a much more ergonomic lifejacket that adapts to the shape of the wearer for enhanced comfort.
This, combined with the lifejacket’s slimline profile and the reduction in EBS size, takes into consideration the restrictive space and movement within the helicopter cabin – allowing for greater freedom of movement for the wearer during transit.
E2S Upgrades Its Signalling Beacons With Super Bright Outputs and Additional
Configuration Options E2S Warning Signals is committed to a programme of continuous product improvements in response to technology advances, regulatory changes and customer feedback.
The latest products to be upgraded are the B350TLA traffic light warning signal beacons that feature a compact 100 x 140mm housing, ideal for space constrained applications or for mounting directly onto machinery. The larger 140 x 177mm B450TLA units have also been upgraded. The light engine for both is an array of 18 high output white LEDs, which give super- bright outputs up to 356 Candela. The ultrasonic welded diffused lens determines the output light colour: Amber, Blue, Clear, Green, Red, and Yellow are standard, enabling on-site
reconfiguration of colours and greater flexibility in inventory management. There are now seven flash patterns, including a temporal pattern for greater effectiveness, in addition to a steady output for status indication.
The included connector enables multiple units to be assembled into stacks and dual pluggable terminals simplify cable installation for looped installations. The operating voltage are ranges are 10-14VDC/16-33VDC and 48-260VAC/ DC, the 1Hz flash operating current is only 88mA @ 24Vdc and the operating temperature is a wide -40°C to +70°C.
Also upgraded with the latest 18 white LED array light source are the STA and STB families of customisable stack signals, UL approved for general signalling applications such as status

indication, security and process control. The STA stacks have a SONF1 compact 100dB(A) alarm horn sounder to give an integrated audible/visual unit; the STB family are beacon-only arrays. Both versions are available with two, three or four units in a stack array which are terminated in a common junction box via a factory-fitted internal wiring loom to give a single external interconnect point. The UV stable PC lenses are available in Amber, Blue, Clear, Green, Magenta, Red and Yellow.
