3. CONTAIN - Close doors to limit spread
4. EXTINGUISH - Only if safe and trained

Post-Fire Actions:

• Patient assessment priority
• Equipment evaluation
• Area ventilation
• Investigation procedures
• Regulatory reporting

Common Mistakes to Avoid

1. Using ABC in patient areas - Respiratory hazard
2. Blocking extinguisher access - Equipment placement
3. Inadequate training - Staff turnover issues
4. Poor maintenance - Missing monthly checks
5. Wrong type selection - Not considering area use

Conclusion

Hospital fire protection requires careful balance between effectiveness and patient safety. Water mist and clean agent extinguishers provide the best protection for most healthcare environments, while specialized areas need specific solutions.

The investment in proper equipment and training is minimal compared to the potential for loss of life and liability. Most importantly, remember that in healthcare, evacuation is often not an option—making the right extinguisher choice critical.
