HVAC Systems and Laboratory Design
"Laboratory hoods and biological safety cabinets are the primary means of controlling hazardous exposures to laboratory personnel. Understanding the design process and how to evaluate laboratory HVAC Systems is the key to providing a healthy laboratory environment."
—Pam Greenley, CIH
This two-day seminar combines lecture, hands-on laboratory work, and group activities. You will learn basic airflow principles and the exhaust requirements of ventilation equipment, OSHA, ANSI, ASHRAE and NFPA regulations, Fume Hood Testing and Laboratory Controls. All course concepts are tied together in an activity where you learn the critical questions to ask when reviewing mechanical drawings.
All presentatoins are interactive, encouraging class discussion.
Participants will learn:
- to define basic ventilation terms and ventilation equations
- types and sources of pressure losses in local exhaust systems
- requirements of sizing fans
- appropriate uses for different airflow measuring instruments
- OSHA, ANSI, ASHRAE, NFPA regulations
- exhaust requirements for fume hoods and biosafety cabinets
- how to conduct a fume hood survey
- how to measure airflow in round and rectangular ducts
- basic principles of lab ventilation control
- lab pressure relationships
- the lab design process
- how to read mechanical drawings
- questions to ask when reviewing mechanical drawings
