Ex ia ex ib intrinsically safe cable glands designed in such a way that the energy of any spark is lower than that can ignite a flammable mixture.
Ia is designed to a higher integrity and can be used in zone 0 hazardous area locations whereas ib is only suitable for zone 1 2 locations.

Flameproof explosion proof protection methods.
In north america metal conduit must be used for field wiring.
Imposes strict requirements for wiring methods in these locations.
As you might suspect explosion proof wiring is typically much more expensive than intrinsically safe wiring.
In europe and elsewhere suitably rated cable is connected directly to the equipment using certified flame proof cable glands.
So cable glands and seals may need to be considered but they are of lighter construction as they are not required to cool exploding gases only to prevent the flow of gases.
