• Review and comply with the USG Design Criteria for Laboratories
• Review and comply with the Georgia Tech Yellow Book Design Standards.
  • Comply with the Yellow Book building-specific laboratory controls requirements in the following buildings:
    • Ford ES&T (147) Building
    • U.A. Whitaker (165) Building 

If compliance is not met in any section of the USG Design Criteria for Laboratories or GT Yellow Book, the Design Professional must submit a variance request. Refer to EH&S Guidance Document for Requesting a Lab Variance from the Board of Regents.

• Conduct a thorough review of the chemical inventory to comply with NFPA 45 requirements

Lab Unit Fire Hazard Classification

• Determine fire hazard class
• Comply with the requirements of the fire hazard class

Safety Data Sheets (SDS)

• Chemical SDS hardcopies are not required.    

Flammable Storage Cabinets

• Cabinets do not require venting per Fire Safety Office.
• A statement at each flammable storage cabinet indicated in the drawings denoting the amount of material being stored as referenced from the Chemical List.    

• Piped Systems: Stainless steel with mechanical joints (Swagelok) or Orbitally welded joints.
• Code Compliance: Identify when specific piping materials are required.
• Cylinders: More than 4% Hydrogen (H2) in a gas mix considered dangerous and requires monitoring. H2 does not need to be inside a gas cabinet.
• A emergency gas shutoff button is required for two or more gases outlets per NFPA 45 State Fire Marshal modifications.  
• Include shut-off for two or more gases that serve a experimental equipment per GT Fire Marshall.  
• Gas shut-off is not required for inert gases per GT Fire Marshal.

Dangerous Gas Monitoring System

• Coordinate with EH&S on the DGMS toxic gas alarm Georgia Security dialers
• Ford ES&T Dialers: (4) Georgia Security dialers that should be in test when working with DGMS at ES&T 03-1501; 03-1901; 03-1633; 03-1640 
   

• Fume Hoods
  • Select between variable or constant air volume based on the building's exhaust systems.
  • Ensure ASHRAE 110 testing (see below) for all new fume hoods.
• Air Valves
  • Material selection must meet code and PI research needs.
  • Approved materials: Aluminum, Stainless Steel, Baked Phenolic Coated.
• Fume Hood Chemical Exhaust Ducts
  • Welded stainless steel construction.
  • Slope exhaust ducts back to the hood.
     

Fume Hood Certification (ASHRAE 110)

• Required for:
  • New installations
  • HVAC modifications
  • Service adjustments inside the hood
• ASHRAE Testing Procedures:
  • Face Velocity Measurement – Average airflow reading.
  • Smoke Visualization – Observing turbulence at the front.
  • Tracer Gas Test – Sulfur hexafluoride contamination detection.
• ASHRAE Test Types:
  • As Manufactured (AM): Factory testing.
  • As Installed (AI): Post-installation, empty hood testing.
  • As Used (AU): In-use testing with equipment.

Gloveboxes

• Test fit with shop drawing layout.
• Purge exhaust material must comply with code and PI research.

Vacuum Pumps

• Sch 80 PVC recommended as a cost-effective solution for exhaust.
• Specify chemicals involved.
• Selection must meet PI's vacuum level and flow rate needs.
• Confirm oil-less, diaphragm technology specifications.
• Define pump exhaust and fume hood base cabinet exhaust setup.

Snorkels, Task Exhaust and Point-of-Use Ventilation

• No in-line fans or back-draft systems.
  
   

• Classified as Class I, II (A1, A2, B1, B2), or Class III.
• Reference: Biosafety Cabinet Guidelines (Biosafety Manual by EH&S).
  
   

Casework and Fume hoods should match building standards.  Consult with the GT PDC Project Manager on the specification, material and color selections. 

• Eyewash: Cold water supply only. No mixing valve required.
