229 Neb. Admin. Code, ch. 2, § 005

Minimum clearance for pressure vessels at sides and back wall shall be three feet. Where a pressure vessel manufacturer identifies in the Installation Manual or any other document that the unit requires more than three feet clearance, those dimensions shall be followed. Pressure vessels having man ways shall have five feet of clearance between the man way opening and any wall, ceiling or piping that will prevent a person from entering the pressure vessel. Clearance in front of the pressure vessel shall be sufficient for operation, maintenance and repair but not less than three feet. The Chief Inspector may waive the minimum clearance requirements of this section if the following requirements have been met:

A. The installer of the pressure vessel shall make written request to, and obtain written approval from, the owner and the owner's insurance company or Authorized Inspection Agency to use the proposed minimum clearances; and

B. The installer shall make a written request to the Chief Inspector to use the agreed upon minimum clearances. This request shall include copies of the approvals noted in 229NAC005.A above; and

C. There remains adequate clearance for inspection, maintenance, operation and repair of the pressure vessel.
