Infrasound waves cease kitchen fires, however can they change sprinklers?

“I would want to see full-scale testing that includes typical residential fires like furniture and mattress fires, cooking fires, electrical fires, and attic or exterior ember exposures,” he added. “It should also cover different conditions like open and closed doors, varying ceiling heights, crosswinds, obstructed fuel packages, and whether the fire comes back after the system shuts off.”

Similarly, Michael Gollner, a professor of mechanical engineering on the University of California, Berkeley, and an skilled 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 academic paper, which discovered that “acoustics alone are insufficient to control flames beyond the incipient stage.”

By distinction, “Fire sprinklers are extensively tested and certified by standards developed by the fire safety community over many years,” he emailed Ars. “I think this product needs to demonstrate the same or better performance with the same reliability before it can be considered to replace any existing safety measure. While I am absolutely supportive of out-of-the-box thinking, lives are truly at stake, and new technologies must carefully demonstrate effectiveness and reliability before being entrusted by society.”

Dozer time

As for the Contra Costa County firefighters who hosted the demonstration, they’re curious to see extra. Deputy Fire Chief Tracie Dutter informed Ars that the company doesn’t advocate particular merchandise, however it does attempt to perceive the makes use of that new expertise can have.

“Sonic representatives indicated they are exploring opportunities to partner with fire departments to test this technology on a bulldozer,” Dutter mentioned.

“The District would be open to testing this system on one of our dozers,” Dutter added, to “better understand its limitations and potential failure points.”

With new tech like this, firefighters additionally need to perceive what “long-term maintenance requirements” it has, whether or not “routine testing or calibration is required to ensure reliability,” and “how system failures such as a malfunctioning detector or acoustic generator are identified and communicated to an owner.”
