Answer: C

Explanation:

The outdoor storage of tires is regulated because tires pose significant fire hazards due to their combustibility and difficulty in extinguishment. According to NFPA 1, Fire Code, Section 19.2.2:

Storage of more than 400 tires outdoors requires a permit.

This threshold ensures that large quantities of tires are managed under specific fire safety requirements, such as spacing, clearance, and firefighting access.

Tires can generate intense heat, dense smoke, and toxic gases when burning, requiring careful oversight.

Storage quantities below 400 tires may not require a permit but still must adhere to basic safety practices.
