This technical memorandum describes the evaluation of the power stun gun as a personal protection device in the following two situations; 1. Measurement of generated current and comparison with simulated threshold levels. 2. The effects of current pulses on animals such as pigs. It was found that in the first situation that the units tested delivered a net charge of 27.5 which could induce fatal fibrillation to the human heart. The second situation evaluated the effect of current pulses on pigs in two stages. The first stage analyzed the effects of the stun guns on a normal open chested pig, while the second analyzed the effects of stun guns on pace-maker implanted pigs. The stage one results were: 1. Stun gun could create permanent burn marks on the skin. 2. With the pigs skin moistened with water the guns paralysing effects were increased. 3. The pigs heartbeat during excitation changed but returned to normal when the excitation was removed. 4. The use of the smallest stun gun (no. 3) caused short stoppages of the heartbeat, the heart resumed normal operation once excitation was removed. 5. The larger, stronger guns (nos. 4 & 5) resulted in repeated heart stoppages, the heart had to be defibrillated. During the second stage the effects of the stun guns on a pace-maker implanted pig were recorded. Stun gun no. 3 (the smallest) had little effect on the heartbeat rate whereas gun no. 5 (the largest) stopped the heart during excitation. Once the excitation was removed the heart
