The companies on site and the hazardous-area types a handset is likely to meet there.
The refinery is about 50 km from the Taj Mahal in Agra and lies in the Delhi-Agra corridor, so road logistics are straightforward. Summers are generally hot and dusty.
Mathura is inland and is supplied with crude through the Salaya-Mathura pipeline, a 2,663 km line from the Gujarat coast, so there is no marine terminal.
The refinery received the Best of All Rajiv Gandhi National Quality Award in 1998, and a corporate postal stamp was issued for its environmental contribution.
Mathura Refinery, Indian Oil's sixth refinery, was commissioned on 19 January 1982 after construction began in October 1972, so its older units are over 40 years old.
The refinery processes low-sulphur Bombay High crude, imported Nigerian low-sulphur crude and high-sulphur Middle Eastern crude, so process conditions vary between crude types.
Mathura city is 162 kilometres south-east of Delhi and about 15 kilometres from Vrindavan, on the Yamuna river.
A hazardous area is a place where flammable gas, vapour or combustible dust may be present. Standards divide these into zones: Zones 0, 1 and 2 for gas and vapour, and Zones 20, 21 and 22 for dust. Zone 1 and Zone 21 are the tier where an explosive atmosphere is likely to occur in normal operation, which is where the IS-04Z1 is designed to work. Anything carried in must be marked for the zone, gas group and temperature class of the area.
No certificate has been issued for the IS-04Z1 yet, so it must not be taken into a classified area until the certificate covering it exists and the site operator has accepted it.
