"I believe we can create systems that can detect, deter, and ultimately stop a shooter within a building for a comparable cost as, or less than, fire suppression systems."

Axon said it would use virtual reality headsets for training, and that all decisions on whether to use a Taser would be made by an "authenticated and authorized human operator who has agreed to take legal and moral responsibility for any force actions initiated."

Axon plans to develop "a remotely operated, non-lethal drone system that we believe will be a more effective, immediate, humane, and ethical option to protect innocent people," Smith said in a statement.

"Reasonable minds can differ on the merits of police-controlled Taser-equipped drones — our own Board disagreed internally — but we unanimously are concerned with the process Axon has employed regarding this idea of drones in school classrooms," the ethics board said.

Citron said that Smith has otherwise been attentive to the ethics board, attending its meetings personally and often accepting its advice. She said she believes Smith is moving ahead with the drone idea out of a genuine desire to eliminate firearms deaths.

double speed setting for fan, while the door is closed and another while open. To ensure the chemical vapours are remove when the user open the door to retrieve the chemicals.

Axon CEO Rick Smith said that he has been exploring such a system for years and even published a graphic novel about it, and that he had now run out patience with the "fruitless" national gun debate.

Designed to operate 24/7 to protect the user and chemicals.  Energy consumption of the Erlab Captair 834 Smart Chemical Storage Cabinet is only 65 W.

The board is advisory, and Axon management isn't required to follow its guidance. Its members include privacy advocates, former police chiefs, civil rights advocates and computer scientists.

The board said Axon was pursuing a "notable expansion" of what was previously under consideration, potentially making the technology available to more clients than just policing agencies and placing surveillance cameras in schools to stream real-time to police.

Axon, formerly known as Taser, is based in Scottsdale, Ariz., and has long been at the center of public debates around police and security equipment. Hundreds of people have died after police used Tasers on them, according to news media tallies, and Axon's police body cameras have raised privacy concerns.

Smith planned to answer questions about the idea Friday at 1 p.m. Eastern on the Reddit forum "Ask Me Anything," Axon said.

Three years ago, in response to a report from the ethics advisory board, Axon said it would not add a facial recognition feature to its cameras.

Erlab chemical listed of over 600 chemicals indicating the molecular filter capacity at 1% of the PEL-TWA of the chemicals.

"There's a lot of disappointment, but a lot of us don't want to be hasty and lose the chance to have an influence," she said. "If we all resign, then who's there?"

"Do not consider attaching any items such as these to a drone because operating a drone with such an item may result in significant harm to a person and to your bank account."

The company behind the Taser brand of stun guns said Thursday that it plans to put its weapons on drones and sell the devices as a way to stop shootings in American schools, an idea that drew an immediate public rebuke from the company's ethics board.

"There are over 10 million fire hydrants pre-emplaced in the United States, and every modern building has fire suppression systems to contain fires until fire-fighters can arrive," he said.

"Now is the time to make this technology a reality — and to begin a robust public discussion around how to ethically introduce non-lethal drones into schools," he said in his statement.

But an ethics advisory board that Axon set up in 2018 to guide the company's work on artificial intelligence warned that Axon was rushing the adoption.

Danielle Citron, a member of the ethics board and a University of Virginia law professor, said it was possible that some or all board members would resign because of Smith's decision.

The idea of armed, remote-controlled, flying robots appeared long ago in science fiction, and U.S. authorities have long sought to prevent their use among civilians. The Federal Aviation Administration issued a reminder in 2019 that operating a drone with a dangerous weapon attached was illegal without FAA authorization.

Investors reacted positively. Axon's share price rose 5.8 percent Thursday, compared to a 1.8 percent rise in the S&P 500.

The ethics board said that the idea of a Taser-equipped drone was brought to the board more than a year ago, and that after lengthy deliberations, a majority of the board last month voted against Axon moving forward even with a limited pilot project.

2 identical molecular filters located below and above a fan/detection chamber ensuring no chemical escape when the lower layered filter reached its saturation. Upper layered filter will replace the saturated lower layered filter. Upper layer will be replaced with a new molecular filter.

Erlab Captair 834 Smart is the 2 doors chemical storage cabinet with capacity to store up to 160 bottles of 500 ml chemical.  834 Smart adopted exclusive Erlab filter technology, that approved by  AFNOR NFX 15-211 and SEFA 9 filtration efficiency standard (classes 1 and 2).  The configurable filtering system can be adapted to filter gases, solvents, powders and particulates keeping the user, chemical and the laboratory are protected with efficiently recirculating air within the room, free from any toxic hazardous chemicals.  It achieves optimum air change per hour, to ensure the chemicals is store and segregate in a safe conditions.

"Perhaps you've seen online photos and videos of drones with attached guns, bombs, fireworks, flamethrowers, and other dangerous items," the agency said then.
