What is one of the elements included in hangar protection systems?

Draft curtains to manage heat is an essential component of hangar protection systems. These curtains help control the airflow within aircraft hangars, which can be crucial in maintaining temperature and minimizing the risk of fire. By preventing heat from escaping or cooling air from entering, draft curtains contribute to the overall effectiveness of the hangar’s environment, particularly in protecting against combustible materials that may be present.

In contrast, while manual fire hoses and fire extinguishers are important safety equipment in hangars, they are not specific elements of a protection system designed to manage the internal environment. Special coatings on walls can enhance fire resistance but do not directly address heat management in the way that draft curtains do. The focus on heat management through systems like draft curtains is a proactive measure aimed at reducing fire hazards, making it a key element in maintaining safety standards within aircraft hangars.
