Analysis Claiming 'TASER™ Danger' Miscalculates Safety Threshold by Factor of 100
Report Applied Incorrect Standard to Evaluate TASER Output
SCOTTSDALE, Ariz. - TASER International, Inc. (Nasdaq: TASR), a market leader in advanced non-lethal devices, today responded to a report presented at the American Academy of Forensic Sciences conference in New Orleans wherein Mr. James Ruggieri presented an erroneous paper claiming that the electrical output of the TASER M26 is above the fibrillation threshold for 50% of the population.
"Mr. Ruggieri made a significant miscalculation, leading him to an insupportable conclusion," noted Max Nerheim, Vice President of Research and Development for TASER International, Inc. "Mr. Ruggieri's assertions are predicated on published safety guidelines in International Electrotechnical Commission (IEC) 479-1. Unfortunately, the standards published in IEC 479-1 are only applicable to low frequency, continuous duty cycle, AC electrical currents of less than 100 Hz, such as one would experience from an electrical wall outlet and not the output one would receive from a TASER device. Rather, the TASER M26 output is a pulsed, damped sine wave current with a frequency equivalent to 50,000 Hz. High frequency and pulsed outputs are covered under IEC 479-2, which indicates that the fibrillation threshold for currents similar to the TASER M26 are 100 times greater than the standard in IEC 479-1 errantly used by Mr. Ruggieri," continued Mr. Nerheim.
"In fact, there are three separate methodologies within IEC 479-2 which demonstrate the TASER M26 output to be significantly below the IEC fibrillation threshold. The appropriate standards under IEC 479-2 are consistent with data from both animal experiments and over 100,000 human volunteers, including myself and every other senior manager and engineer at TASER International, without a single incident of ventricular fibrillation. This is also backed by the over 66,000 actual field use applications by law enforcement. His misrepresentation was further evidenced by the remarks and questions raised by medical experts in attendance. It is disappointing that Mr. Ruggieri chose not to allow us to provide this technical feedback by reviewing his opinions before presenting them in a public forum."
"Furthermore, I was surprised that Mr. Ruggieri did not notice the error with his results as they are diametrically opposed to the dozens of independent studies of numerous government agencies that have concluded the TASER system, while not risk free, is generally safe.
