Answer: (C)

The recommended course of action for fighting a small fire involving a substance identified by UN/NA I.D. number 2553 can be found in the orange section of the Emergency Response Guidebook (ERG). This section is specifically dedicated to providing emergency response information for hazardous materials and includes detailed guidance on the appropriate firefighting measures for various substances.

UN/NA I.D. number 2553 pertains to substances classified as "Hydroxylamine." For such materials, the ERG offers essential guidance on fire extinguishing methods, including the types of extinguishing agents that are safe and effective to use. The orange section allows responders to quickly locate instructions regarding common hazards, emergency actions, and first-aid measures specific to that substance, ensuring a structured response during an emergency involving hazardous materials.

This information is vital for ensuring the safety of both the responders and the environment during a chemical incident.
