  2. Equivalence Process for Pressure Vessels at BNL • If a new pressure vessel or pressurized piping cannot be manufactured to comply with the ASME codes, what is the equivalence process at BNL? • Equivalence means the solution must provide equivalent protection. Review and documentation must meet three basic requirements: • Design drawings, sketches and calculations must be reviewed by the BNL Pressure and Cryogenic Safety Sub-Committee • Qualifications of personnel used to perform examinations, inspections, fabrications and testing must be documented • Documents such as qualification records, materials certifications, narrative descriptions of design, pressure conditions, testing, inspection, operation, repair and maintenance of the pressurized system must be retained by the Department in a formal document control system • BNL approved equivalences for pressurized systems in the past two years have resulted in use of high-pressure piping that did not meet code requirements, alternatives to welding inspections, use of new materials such as niobium, and an increase in originally allowed operating pressure for a pre-2007 system

  3. Other Equivalence-Like Processes at BNL • National Electrical Code Requirements • Request must go through the Lab Electrical Safety Committee • Example: non-tray rated cable in tray at STAR and PHENIX • Example: test GFCIs before use rather than monthly • OSHA Requirements • Formal BNL waiver needed • De minimis conditions only • Example 4-31: §1910.27(b)(1)(ii) allows 12 inches as the maximum distance between ladder rungs. Where the rungs are 13 inches apart, the condition is de minimis • NFPA Requirements • Request must go through BNL Fire Safety Committee • Example: Fire barriers at STAR and PHENIX • SBMS Requirements • Formal BNL waiver needed • Subject Matter Expert and Management System Steward must sign • Example: Na22 in soil at RHIC

  4. Safety Notes • ISO 14001 and OHSAS 18001 Registrations in May • Refresher training in late April • Bring ODH monitors to Ann Marie Luhrs for calibration • Due every 6 months • Inspect ODH escape packs monthly • Check: hose connections, fill gauge, hood • Initial tag each month after check
