The entire purpose of an air vest is to deploy during a fall. But what happens next? The aftermath of an activation involves a strict protocol to return the vest to a safe, operational state. The usage scenario now shifts from emergency protection to a methodical reset process. Mishandling this process can render the vest permanently unusable or, worse, unreliable for future use.
The first step after a fall is to ensure you are medically sound. Once safe, carefully assess the vest. It will be fully inflated and must be deflated before removal. Most vests have a deflation valve or tube; open it to release the CO2 gas. Never use a sharp object to puncture the bladder. Once deflated, you can unclip the lanyard and remove the vest.
The deployment is a single-use event for several key components. The CO2 canister is now empty and must be replaced immediately. Never attempt to re-use a spent canister. The activation mechanism must be professionally reset. For mechanical tether systems, this often means replacing a spent cartridge within the trigger unit. For electronic systems, the trigger module may need to be sent to the manufacturer or a certified agent for resetting and diagnostics.
Furthermore, the inner airbag bladders must be carefully inspected for any damage that might have occurred during the inflation process or the fall itself. While designed for a single impact, they should be checked for integrity. Choosing to ignore this protocol and simply screwing in a new canister is extremely dangerous. The vest must be fully reconfigured according to the manufacturer's exact instructions. After any deployment, it is also a wise practice to have the entire vest inspected by an authorized dealer to ensure no hidden damage has occurred to the shell or seams. Following this strict protocol is the only way to guarantee your vest will be ready to protect you again.
