What does NFPA 10 provide standards for in relation to portable extinguishers, including Class K?

• A. Selection, inspection, maintenance, and use of portable extinguishers
• B. Designs and installation of building fire suppression systems
• C. Training requirements for emergency responders
• D. Fire investigation procedures

Answer: (A)

NFPA 10 sets out how portable extinguishers should be chosen to match the hazards present, how they must be inspected to ensure they are charged, accessible, and in good condition, how they are maintained and serviced, and how they should be used by occupants during a fire. The inclusion of Class K means kitchens dealing with cooking oils and fats have extinguishers that follow the same standards, with considerations specific to those fires, so they’re appropriate and ready for use. This helps ensure the right extinguisher is available where needed, kept up to date, and used safely for small fires while evacuating if the situation requires it. Other topics listed in the options pertain to different parts of fire protection—such as designing and installing building suppression systems, providing training for responders, or conducting fire investigations—and are not covered by portable extinguisher standards.
