About Incident Response System
- IRS is a combination of facilities, equipment, personnel, procedure and communications operating within a common organizational structure, with responsibility for the management of assigned resources to effectively accomplish stated objectives pertaining to an incident.\
- Functions:
- In line with administrative structure and DM Act 2005, Responsible Officer (RO) is designated at the State and District level as overall in charge of the incident response management.
- RO may delegate responsibilities to the Incident Commander (IC), who in turn will lead/manage the incident through Incident Response Teams (IRTs).
- IRS functions through Incident Response Teams (IRTs) in the field. An IRT is a team comprising all positions of IRS organization; headed by Incident Commander (IC).
- On receipt of Early Warning, RO activates IRTs. In case of a disaster without any warning, local IRT will respond and contact RO for further support, if required.
- IRTs pre-designated at all levels, i.e. State, District, Sub-Division and Tehsil/Block.
- IRT’s lowest administrative unit (Sub-Division / Tehsil / Block) will be the ‘first responder’.
- If the incident becomes complex and beyond the control of local IRT, higher level IRT will be informed / take over the response management. In such cases the lower level IRT will merge with the higher level IRT.
- When lower level of IRT merges with a higher level, IC of lower level may play the role of Deputy IC or Operations Sections Chief (OSC) or any other duty that the IC of higher authority assigns.
