While en route, a tractor-trailer hauling a Class 8 corrosive is involved in a crash, and the other driver is admitted to the hospital for treatment of her injuries. What must the hazmat carrier do?

49 CFR 171.15(b)(1)(ii) (notice — hospital admission trigger, within 12 hours)

Drivers are often the first person able to recognize that a reportable incident has occurred. Knowing the injury/death trigger applies regardless of whether the hazmat itself was damaged can be the difference between a legally required call being made within hours versus missed entirely.
