Ensure the fire safe design and operation of instructional, educational, and industrial laboratories using chemicals! NFPA 45 outlines the maximum allowable quantities of liquids and gases, as well as requirements for laboratory ventilating systems and hoods. Look to the 2000 edition of this respected Standard for:
Modified laboratory separation requirements, including more stringent requirements for non-sprinklered laboratories. Non-sprinklered laboratories of Class A or B and Class C (over 10,000 square feet) are now prohibited.
Expanded requirements and advisory information for compressed and liquefied gases. Maximum quantity requirements are clarified based on four listed gas classifications.
Modified laboratory ventilating systems and hood requirements, updated to address the use of VAV (Variable Air Volume) laboratory ventilation systems
