ESH issues 1

• ESH must be planned from the start
• ESH can be expensive
• Its more expensive if you dont do it right

3
ESH issues 2

• Cryogenic safety
• Pressure Vessel safety
• OSHA
• Confined Spaces
• Oxygen Deficiency

4
Cryogenic Safety 1

• Material properties
• Trapped volume relieving
• Thermal expansion, but not the contents
• In a large commercial installation this comes
  along free

5
Cryogenic Safety 2

• Operating procedures
• Key to safe operation of equipment
• Manpower training
• Avoidance of injuries
• Successful physics program

6
Pressure Safety

• ASME Boiler and Pressure Vessel Code
• ANSI Pressure Piping Codes
• API 620
• Local building code
• In a large project this is also probably free

7
OSHA

• Fermilab adheres to OHSA standards
• In off-site adventures OSHA is mandatory

8
Environmental Issues

• Water
• Air

9
Oxygen Deficiency Hazard 1

• Large quantities of stored cryogens
• 26.25 Acre-ft for large detector
• Possible issues
• Tall stack for vapor release dispersion
• Dyke to manage catastropic spill
• Placement of control and machinery areas

10
ODH 2

• Near detector would also have this issue
• Vents piped outside
• Ventilation system to catch leaks that exhausts
  outside
• Potential ODH classification?

11
Confined Spaces

• Vessels must be designed with this in mind
• Will affect Installation and Maintenance
