The following principles provide the basis for managing confined space entry :
Each Location where people enter confined spaces shall develop and implement a written confined- space entry program that applies the principles of confined-space entry described in this standard, incorporates the mandatory requirements of this standard, and is compliant with local legislation.
All confined spaces must have a permit for entry unless exempted by the mandatory requirements in Section 6.6
− Confined spaces shall only be entered if no other approach to task completion is practical. Prior to entry, all possible controls shall be applied to prevent personal exposure to potential hazards.
