ERMA Incident Categories
Minimal (Level 1)• Little discernable effect on people or the
environment, minor effect on property or some social disruption, controls adequate
Minor (Level 2)• Localised, short term, minor effect on people or
the environment, property damage, some social disruption to surrounding area, controls adequate
Spillage LegislationERMA Incident CategoriesModerate (Level 3)• Significant longer term damage to people, property
or the environment, one death, disruption to surrounding community, controls appear adequate but may require follow-up
Major (Level 4)• Significant irreversible damage to people, property
and the environment, more than one death, major social disruption, a system/control failure or lack of adequate controls, public and political interest
Spillage Legislation
ERMA Incident Categories
Massive (Level 5)• Major damage to property, communities and the
ecosystem, including species loss, multiple deaths, significant economic effect, substantial system/control failure resulting in public and political outrage
While not directly aligned with the CDEM levels (Section 2.3) they are similar, with increasing support required as the incident category rises.
