The storage of flammable gases must be reported in accordance with which municipal law?

The correct answer is based on municipal laws that govern the reporting and storage of hazardous materials, including flammable gases. Law 209-U specifically pertains to the storage and reporting requirements for certain flammable substances, including compressed gases. This law establishes guidelines that ensure public safety by enforcing proper handling, storage, and reporting protocols for flammable materials.

Understanding the importance of Law 209-U is crucial for compliance and safety in various applications, particularly in settings where flammable gases are handled or stored. The law aims to minimize the risk of incidents related to fire hazards and explosions by mandating the proper reporting of quantities and storage practices to relevant authorities.

In other jurisdictions and laws, such as 201-A, 300-B, and 250-C, different safety standards and reporting requirements may apply, but they do not directly address the specific needs and conditions set forth in Law 209-U related to flammable gas storage. This is why 209-U is the relevant choice in this context.
