The amendments to parts A and A-1 of the IGF Code amend:

• Explosion relief systems and designed accommodation of overpressure for internal combustion engines; and

• Fire protection requirements for the separation of fuel containment systems from other spaces, and for type C fuel storage hold spaces.
