IMPORTANT SAFETY INFORMATION
At VEMCO, we make every effort to ensure all of our products are as safe as possible. However,
some hazards are unavoidable when deploying equipment underwater.
Your safety is important to us, so please read this list of cautions carefully, and follow the directions
below.
Case Pressurization
If a case leaks underwater, the inside pressure will increase to match the pressure at that depth.
This extra pressure will release as the unit is brought to the surface; however, if the leak is small,
that pressure release will be very slow. This will result in the case still being highly pressurized at
the surface.
Such a case can fly apart with explosive energy and represents a serious safety hazard.
Battery Breach
Lithium batteries contain chemicals that represent a serious health hazard
– particularly
when combined with water.
Most VEMCO receivers and acoustic releases use this type of battery. A battery breach can occur if
a VEMCO receiver or acoustic release becomes damaged and water gets into the internals.
In addition, the reaction of the released chemicals with water in the sealed case can lead to case
pressurization, which could be explosive.
Safety Features
VEMCO receivers and acoustic releases that are designed to be deployed at depth may be
equipped with a pressure release that will activate when internal pressure reaches a certain level
above external pressure. This mechanism can fail if a receiver or acoustic release has been
damaged or if the release is blocked or fouled.
More details regarding specific receivers or acoustic releases can be found in the corresponding
user manual.
