Frequently Asked Questions
Who is authorized to perform a hazardous laboratory fire safety evaluation in Florida?
In the State of Florida, complex hazardous chemical or industrial laboratory evaluations require a licensed Professional Engineer (P.E.) with proven expertise in fire protection engineering and chemical hazard classification. Due to the high-stakes intersection of the Florida Building Code, Florida Fire Prevention Code, and NFPA standards, these reviews require specialized authority to certify compliance for municipal building officials and state fire marshals.
What is a Maximum Allowable Quantity (MAQ) evaluation?
An MAQ evaluation is an inventory-based calculation of the maximum volume of hazardous, flammable, or reactive chemicals that can legally be stored and used within a specific control area and laboratory classification. Exceeding these thresholds without implementing specialized controls such as fire barriers, continuous mechanical ventilation, or robust suppression systems constitutes a severe code violation and triggers catastrophic insurance and operational risks.
When does a university or industrial facility need a revised NFPA 45 evaluation?
A revised hazardous laboratory evaluation must be performed whenever there is a change like a modification to the laboratory’s operational footprint, a change in the chemical classes or volumes being introduced, an update to the laboratory ventilation systems, or during a building occupancy classification change. Regular periodic audits are highly recommended to ensure dynamic lab spaces remain fully code compliant and prevent fire inspection violations.
