The background color used from the source to the outlets of a nitrous oxide medical gas system is blue. This is the standard color coding for nitrous oxide cylinders and pipelines in medical gas pipeline systems12. The color coding helps to identify the gas type and prevent accidental misconnections or cross-contamination3. The color coding also indicates the pressure and flow characteristics of the gas system4. References:

NFPA 484: Standard for Combustible Metals, 2020 Edition, provides requirements for the storage and handling of aluminum powders, flakes, and pastes. This standard covers the production, processing, finishing, handling, recycling, storage, and use of all metals and alloys that are in a form capable of combustion or explosion. It also covers operations where metal or metal alloys are subjected to processing or finishing operations that produce combustible powder or dust.NFPA 484 includes specific chapters for various metals and alloys, including aluminum and aluminum alloys12

The duration of required fire flow in public supply systems depends on the type of occupancy, construction, and exposure of the building, as well as the availability and reliability of the water supply. According to NFPA 1, Fire Code, Table 18.4.5.1.2, the minimum duration of fire flow for most occupancies ranges from 1 to 4 hours, with some exceptions for high-rise buildings, health care facilities, and special hazards. The fire flow duration is intended to provide enough water for fire suppression and exposure protection until the fire is under control or extinguished.References: NFPA 1, Fire Code, 2023 Edition, Section 18.4.5.1.2 and Table 18.4.5.1.2; NFPA Fire Protection Handbook, 21st Edition, Chapter 9, Section 9.2.2.

Two-dimensional models are not a common type of road tunnel fire models. Most road tunnel fire models are either one-dimensional, zone, or field models. One-dimensional models use a simplified approach to describe the fire and smoke behavior along the tunnel axis, assuming uniform conditions across the tunnel cross-section. Zone models divide the tunnel into two or more zones, each with uniform properties, and apply mass and energy conservation equations to each zone. Field models use computational fluid dynamics (CFD) to solve the governing equations for mass, momentum, energy, and species transport in a three-dimensional grid, capturing the spatial and temporal variations of the fire and smoke phenomena. Two-dimensional models are rarely used for road tunnel fire simulations, as they cannot account for the complex three-dimensional effects of fire and ventilation in tunnels.

An as built plan review is a type of plan review that may provide information about a modification such as the removal of an abandoned underground flammable liquid tank. An as built plan review is conducted after the construction or alteration of a building orsystem is completed and before the final approval or acceptance by the AHJ. An as built plan review verifies that the building or system conforms to the approved plans and specifications and complies with the applicable codes and standards. An as built plan review may also identify any changes or deviations from the original plans that occurred during the construction or alteration process, such as the removal of an underground tank.References:
