Dense urban setting
The refineries sit in the Mahul-Chembur area within the metropolitan region, which Wikipedia notes is surrounded by a number of chemical plants, so site access and security controls are normally strict.
Mumbai has two large refineries at Mahul and Trombay, BPCL's at about 13 million tonnes a year and HPCL's at 9.5 million tonnes a year. Refining, petroleum terminals and chemical plants create Zone 1 areas, and crude arrives from offshore fields such as Mumbai High. Distribution partners for Mumbai, Maharashtra are being identified ahead of the Q4 2026 launch of the IS-04Z1.

IECEx is the international scheme for certifying equipment used in explosive atmospheres. A certificate of conformity is issued by an accredited certification body against a specific edition of the IEC 60079 standards and carries a schedule of conditions of safe use. It is not a legal requirement in most countries on its own, but many national schemes accept it as the technical basis.
The IECEx certificate for the IS-04Z1 is in progress and has not been issued. The marking target is Ex ib IIC T4, the intrinsic safety concept for Zone 1 gas with the hardest gas group (IIC) and a 135 °C temperature class.
