- Current Version (2024): NFPA 45 emphasizes safety within laboratories, considering factors specific to these spaces.
- Previous Version: The 2002 edition lacked detailed provisions tailored to laboratory needs.
3. Quantity Limits:
- Current Version (2024): Provides updated quantity limits for various hazardous materials, including pyrophoric gases and phosphoric reagents.
- Previous Version: Likely had different or less specific quantity limits.
4. Safety Objectives:
- Current Version (2024): NFPA 45 aims to:
- Limit injuries to occupants at the point of fire origin.
