Final answer:
NIST has recommended alternative firefighting tactics such as drone monitoring, advanced protective gear, and indirect firefighting, which includes attacking the fire from a distance or adjacent spaces when direct entry is not safe.
Step-by-step explanation:
The National Institute of Standards and Technology (NIST) has shown alternative firefighting tactics for scenarios where personnel cannot safely make entry into the fire area.
These tactics include using technology such as drone monitoring for better situational awareness without endangering human lives. Furthermore, the use of advanced protective gear, such as lightweight breathing systems and heat-resistant materials developed from aerospace technology, enhance the safety and effectiveness of the firefighters engaged in combating such fires from a distance or in entering adverse conditions when it becomes necessary.
Including these advances, NIST emphasizes the importance of new approaches like indirect firefighting, which involves attacking the fire from an adjacent space or using the exterior of the building when direct attacks are not possible. This can involve applying water or fire suppressants from the outside or cutting off the fire's oxygen supply to contain and eventually extinguish it.
