Shelter in Place(SIP)

Shelter in Place (SIP) is commonly recommended during emergencies such as chemical spills, industrial accidents, severe weather events, or incidents involving potential airborne contaminants. The purpose is to reduce the risk of exposure to hazardous substances or unsafe conditions outside.
Safety studies on SIP typically evaluate the effectiveness and impact of this protective measure. They may analyze factors such as:

The Objective of this safety study is to improve preparedness, response, and decision-making related to SIP measures, ensuring the well-being and safety of individuals and communities during emergencies.

Shelter in Place (SIP) Philosophy

SIP philosophy for temporary refuge shall be developed and same shall be agreed with the company through Assumptions Register.

Identification of Failure Scenarios

SIP Study shall be in accordance with EERA Study Report and including HSE&S Risk Management best practices. All the identified failure cases and applicable failure cases shall be further assessed (as applicable) for need of a SIP

EERA Stages from accident to Rescue process are illustrated

Identification of locations for SIP

The location of SIP to be identified and marked where mustering from process area and non-process areas into designated Muster Points/safe area is not possible or if the existing/proposed muster points are not safe from all scenarios and the option is to go ahead with SIP for temporary refuge.


All identified SIPs whether existing buildings upgraded to SIP or the new SIPs (portable container type) shall be assessed for their safe use and location in case of emergency scenarios and shall be in line with the standard requirements for SIP and agreed criteria/ philosophy. Thus, it can be concluded that SIP would help in mitigating the critical risks and achieving global benchmarks on Operations & Safety systems at site.
