“I might need to see full-scale testing that features typical residential fires like furnishings and mattress fires, cooking fires, electrical fires, and attic or exterior ember exposures,” he added. “It must also cowl totally different circumstances like open and closed doorways, various ceiling heights, crosswinds, obstructed gasoline packages, and whether or not the fireplace comes again after the system shuts off.”
Equally, Michael Gollner, a professor of mechanical engineering on the College of California, Berkeley, and an knowledgeable in hearth dynamics, informed Ars there’s merely not sufficient info but to indicate that this expertise works higher than sprinklers.
He pointed to a 2018 tutorial paper, which discovered that “acoustics alone are inadequate to regulate flames past the incipient stage.”
In contrast, “Hearth sprinklers are extensively examined and licensed by requirements developed by the fireplace security group over a few years,” he emailed Ars. “I believe this product must show the identical or higher efficiency with the identical reliability earlier than it may be thought of to switch any present security measure. Whereas I’m completely supportive of out-of-the-box considering, lives are actually at stake, and new applied sciences should fastidiously show effectiveness and reliability earlier than being entrusted by society.”
Dozer time
As for the Contra Costa County firefighters who hosted the demonstration, they’re curious to see extra. Deputy Hearth Chief Tracie Dutter informed Ars that the company doesn’t suggest particular merchandise, nevertheless it does attempt to perceive the makes use of that new expertise can have.
“Sonic representatives indicated they’re exploring alternatives to accomplice with hearth departments to check this expertise on a bulldozer,” Dutter stated.
“The District could be open to testing this technique on considered one of our dozers,” Dutter added, to “higher perceive its limitations and potential failure factors.”
With new tech like this, firefighters additionally need to perceive what “long-term upkeep necessities” it has, whether or not “routine testing or calibration is required to make sure reliability,” and “how system failures similar to a malfunctioning detector or acoustic generator are recognized and communicated to an proprietor.”
