BYRNA TECHNOLOGIES INC. ISSUES SAFETY ALERT AND INSPECTION PROCEDURES FOR BYRNA HD PERSONAL SECURITY DEVICES *

Byrna Technologies Inc ("Byrna") has identified a limited number of Byrna HD launchers where the safety may be out of specification. Under certain circumstances, this could result in an unintended discharge of the Byrna HD launcher if the trigger tail is pulled while the safety lever is in the "SAFE" position. The atypical sequence of events that could result in the discharge of a projectile from the affected Byrna HD launchers while in the SAFE position is as follows:

  1. The trigger tail is pulled with the safety lever in the "FIRE" position without a CO2 cartridge installed or with a completely discharged CO2 cartridge. The hammer is then "cocked".

  2. The user then installs a new CO2 cartridge, places the safety lever in the "SAFE" position, and then pulls the trigger tail while the lever remains in the "SAFE" position. In the affected launchers, the hammer hits the "striker" and the launcher discharges.

The sequence of events that would allow the Byrna HD launcher to fire with the safety on is atypical (and violates Byrna's safety instructions and warnings). The Byrna HD launcher should never be directed at another person, unless that person poses a threat to the safety of the user and the discharge is necessary in self-defence. However, as Byrna's mission is to promote safety, we felt it necessary to alert our customers to this potential technical issue. Byrna will perform the factory service upgrade (at no charge) on the affected launchers for any customer who wishes to take advantage of this service program.

To determine whether a Byrna HD launcher is affected by this technical problem, the owner can perform the following test:

PROTOCOL AND TEST PROCEDURE

  1. Find a place outside and away from passers-by.

  2. Point the Byrna HD launcher in a safe direction and ensure that the safety lever on the Byrna HD launcher is pointed upwards to the "SAFE" position. 3.

  3. Keeping the Byrna HD launcher pointed downwards and in a safe direction, carefully remove the CO2 cartridge and magazine from the Byrna HD launcher.

  4. Continuing to hold the Byrna HD launcher pointed downwards and in a safe direction, place your hand under the well and press the breach indicator on the top rail. This will remove any remaining projectile from the Byrna HD launcher.

  5. DO NOT RELOAD A CO2 CARTRIDGE FOR THIS STEP. After removing any remaining rounds from your Byrna HD launcher, install an empty magazine, point the Byrna HD launcher in a safe direction, lower the safety to the "FIRE" position and press the trigger tail firmly. Pay attention to the sound of the trigger - this is the sound it makes without discharging CO2.

  6. Turn the safety lever on the Byrna HD launcher back to the "SAFE" position, load a new undrilled CO2 cartridge as described in the manual. DO NOT LOAD A PROJECTILE.

  7. Pointing the Byrna HD launcher in a safe direction, and holding the safety lever in the "SAFE" position, pull the trigger tail vigorously. If there is a pop, bang or other noise reflecting a discharge of CO2 when the trigger is pulled in step 7 (any noise other than that heard in step 5 from the trigger pull alone), this indicates a discharge of CO2 and the Byrna HD launcher is affected.

If there was no noise indicating a CO2 discharge when the trigger was pulled in step 7, the Byrna HD launcher is not affected by this technical problem and no further action is required.
