Detailed Explanation
Fire extinguisher signage requirements come from NFPA 10 (Standard for Portable Fire Extinguishers):
1. **When Required**: Signs are required when extinguishers are not immediately visible or when cabinets/enclosures obscure them.
2. **Sign Content**: Must indicate "FIRE EXTINGUISHER" or use the standard extinguisher pictogram.
3. **Letter Size**: Minimum 1" tall letters for visibility.
4. **Mounting**: Signs should be mounted above or adjacent to extinguisher location, at a height visible from the approach path.
5. **Additional Markings**: Some jurisdictions require indicating extinguisher type (A, B, C, D, K) on the sign.
6. **ADA Considerations**: While not specifically ADA-required, tactile fire extinguisher signs improve accessibility.
