What type of protection is mandated for large amounts of combustible materials in various locations?

Master streams are mandated for large amounts of combustible materials in various locations because they provide an effective and efficient means of delivering a large volume of water to suppress a fire. Master streams are typically deployed from a fixed or portable apparatus with the capability of discharging a consistent and powerful stream of water, which is essential when dealing with extensive fire loads or when rapid suppression is critical to preventing fire spread.

This type of apparatus can effectively reach high or distant locations where the fire hazard exists and can cover a broader area compared to other options. The use of master streams is particularly crucial in scenarios where water supply must be extensive to manage the significant heat release associated with larger fires. Their design allows for quick setup and operation, making them suitable for aggressive fire control in situations with high fire load, ensuring firefighter safety and efficiency in firefighting operations.

Therefore, the emphasis on master streams aligns with the need for robust firefighting capabilities in environments with substantial amounts of combustible materials.
