ISOLATION
Isolation of a confined space is a process where the space is removed from service by:
- locking out electrical sources, preferably at disconnect switches remote from the equipment.
- blanking and bleeding, securing valves Cargo, ballast, IGS, pneumatic and hydraulic lines
- disconnecting mechanical linkages on shaft-driven equipment where possible, and
- securing mechanical moving parts within confined spaces with latches, chains, chocks, blocks, or other devices.
