In its August 4, 2026 release, UL Research Institutes’ Fire Safety Research Institute identifies water from a standard handline as its first-choice EV suppression tactic and states that added suppression agents are not required. Its guidance also addresses protective equipment, toxic exposures and persistent reignition risk.
This is EV incident guidance. It does not establish approval or test results for any Redline or Thermal Mountain product.
