What materials are check curtains made from?

Check curtains are made from incombustible materials to enhance safety in underground mining operations. The primary purpose of these curtains is to assist with air control and to minimize the movement of smoke and gas in the event of a fire or emergency. Using incombustible materials ensures that the curtains do not contribute to any fire hazards, which is critical in the underground mining environment where flammable gases and dust are present.

Choosing incombustible materials for check curtains aligns with safety regulations and best practices, aiming to protect miners and equipment during a fire incident. Such materials can withstand high temperatures without igniting, therefore maintaining the integrity of the mine's air flow system and ensuring emergency egress routes remain viable.

Materials like wooden planks or plastic sheets would not be suitable, as they can burn and potentially worsen a dangerous situation. Metal frames, while potentially useful for structural support, do not serve the specific function of acting as a barrier to flames and smoke as effectively as incombustible materials.
