- can be effectively and safely managed, and contained within the site, location or installation by the available resources;
- has no impact outside the site, location, or installation.
- Level 2: This is an emergency or an incident which –
- cannot be effectively and safely managed or contained at the location or installation by available resource and additional support is alerted or required;
- is having or has the potential to have an effect beyond the site, location or installation and where external support of mutual aid partner may be involved;
- is likely to be a danger to life, the environment, or to industrial assets or reputation.
- Level 3: This is an emergency or an incident with an off-site impact which could be catastrophic and is likely to affect the population, property, and environment inside and outside the installation, and management and control is done by district administration. Although the Level-III emergency falls under the purview of the District Authority until they step in, it should be the responsibility of the unit to manage the emergency.
