Schedule Overview
Reference Design Preliminary Hazard Analysis
Reference Design Preliminary Hazard Analysis • 40 Hazards Identified in Reference Design PHA • Appendix to TN-0045 Enclosure Reference Design Studies & Analysis • There WILL be differences between the PHA and the design hazard analysis
Reference Design Preliminary Hazard Analysis • Personnel Safety Hazards: – Cable Wrap & Azimuth Mechanical Area • • Confined Space Pinch/Crush Hazard Electric Hazard Low Overhead Clearance – Enclosure Exterior, Catwalk, Personnel Lifts • Fall Hazard • Dropping or Falling Objects – Access Platforms • Fall Hazard • Dropping or Falling Objects (Reference Design)
Reference Design Preliminary Hazard Analysis • Equipment Safety Hazards: – Dropping Objects (tools, fasteners) • • Access Platforms Personnel Lifts Bridge Crane Jib Crane – Abandoned/Unattended Tools – Rotation Conflicts • Cranes/TMA • Enclosure/Personnel Lifts • Equipment/Equipment Fixtures (e. g. Bogie) • Rear Access (M 1 Cart) Door, Track, Guard Rails/S&O Building (Reference Design)
Reference Design Preliminary Hazard Analysis • Environmental Safety Hazards: – None Noted in PHA – Watch List: • • Lubricants Paints Coolant in Utility Wraps Construction Site Environmental Safety – Wildlife
Safety Plans Design Fabrication & Test Transportation Construction Integration, Test & Commissioning Operations
Design for Safety • Enclosure Safety Requirements – Project Documents & General Requirements • • • SPEC-0030 Conditions for Working at the Site SPEC-0031 Contractor Safety & Health Specification SPEC-0035 ATST Hazardous Material and Waste Management Program Interface Control Documents – space allocations, etc. IBC, OSHA/HIOSH, NEC, NFPA, ANSI-RIA Design Safety Factors ~ 1. 5 -2. 2 • LIC and GIS Interface • – Safe as an independent system – GIS over-ride ability – Safety-rated switches and sensors – Allen-Bradley Guard. Logix & Control. Logix hardware Safe Access for Maintenance Procedures – Walkways and Platforms – Lifts
Internal Access Walkways
Design for Safety • Failure Mode & Effects Criticality Analysis (FMECA) – Prevent personal injury – Prevent damage to telescope – Component life and reliability: spares plan • Safety Devices – – – – – Non-back-driveable motors Shock Absorbers Enabling Switches Power-off, Fail-safe components Emergency-Stops Emergency Lighting Emergency Power Egress HMI Maintenance Consoles
Example – Reliability Analysis
Design for Safety • Preliminary Hazard Analysis – Who: AEC-Idom, Marshall, Phelps, Hubbard, Bulau – When: Prior to and during every other monthly meeting – How: Review of hazards and mitigations. Planning and understanding use-cases – Results: 55 Hazards identified so far, divided by phase and zone • Navisworks/Modeling/ Visualization – “getting small”
