The Complete Guide to Fire Extinguisher Classifications: What Santa Rosa Businesses and Residents Need to Know

Understanding fire extinguisher classifications is crucial for proper fire safety in Sonoma County. As your local fire safety experts in Santa Rosa, we'll break down each fire extinguisher class and help you ensure your property has the right protection.
Understanding Fire Classifications
Every fire extinguisher is labeled with letters (A, B, C, D, or K) that indicate which types of fires they can safely extinguish. Using the wrong type of extinguisher can be ineffective or, worse, dangerous.
Class A: Ordinary Combustibles
These extinguishers are designed for fires involving:
- Wood and paper products
- Cloth and textiles
- Many plastics and rubber materials
- Common office and household materials
For Santa Rosa businesses, California Fire Code requires Class A extinguishers in most commercial spaces, with specific placement requirements based on square footage and occupancy type.
Class B: Flammable Liquids
Class B extinguishers are essential for:
- Gasoline and oil
- Paint and solvents
- Grease
- Other flammable liquids
Given Santa Rosa's proximity to wine country, Class B extinguishers are particularly important in wineries and processing facilities where flammable liquids are present.
Class C: Electrical Equipment
Critical for fires involving:
- Computers and servers
- Electrical panels
- Appliances
- Any energized electrical equipment
With the growing tech presence in Sonoma County, Class C extinguishers are increasingly important in office environments and data centers.
Class D: Combustible Metals
Specialized extinguishers for:
- Magnesium
- Titanium
- Sodium
- Other combustible metals
These are primarily needed in manufacturing and industrial facilities.
Class K: Commercial Cooking Fires
Essential for:
- Restaurant kitchens
- Commercial food service operations
- Cooking oils and fats
Per Santa Rosa Fire Department regulations, all commercial kitchens must have Class K extinguishers readily accessible near cooking areas.
Multiple Ratings
Many modern fire extinguishers carry multiple ratings (like ABC) to handle different fire types. This is particularly useful for:
- Small businesses
- Home environments
- General office spaces
Local Compliance Requirements
Santa Rosa businesses must comply with both California Fire Code and local ordinances regarding fire extinguisher placement and maintenance. Key requirements include:
- Annual professional inspections
- Clear access and visibility
- Proper mounting height and locations
- Regular staff training on proper use
