What is the definition of injury?

Under the hazard assessment requirements of 40 CFR Part 68, Subpart B, an owner or operator must document a five-year accident history including all accidental releases from covered processes that resulted in deaths, injuries, or significant property damage on site, or known offsite deaths, injuries, evacuations, sheltering in place, property damage, or environmental damage (40 CFR §68.42(a)). For purpose of the five-year accident history, has EPA defined the term "injury"?

The definition of "injury" is borrowed from OSHA regulations regarding employee injury and illness logs. EPA interprets the term "injury" to include any effect on a human from a release of a regulated substance that requires medical treatment or hospitalization. Medical treatment includes any treatment, other than first aid, administered by a doctor or registered personnel under the supervision of a doctor (see definitions 40 CFR §68.3).
