We have one SVAGRIHA Project which has a blast-proof envelope as the building is located on one of the petroleum plant campuses. This blast-proof envelope does not have any openings/windows as per their norms. However, the fresh air provision (Mechanical) is designed.
An exemption may be given to the project on submission of following documents.
Fire clearance certificate and approval plan.
Undertaking from the client on letterhead with explanation.
Codes, standards, notification for blast-proof building design located on petroleum plant campuses.
