Which type of stopping is required to separate a primary escapeway?

The requirement for a stopping to separate a primary escapeway involves ensuring the safety and integrity of the escape route in the event of an emergency, such as a fire or gas leak. A stopping that is fire resistant and anti-static serves several critical purposes.

Firstly, fire resistance is crucial in a mining environment where combustible materials and gases are present, as it helps to prevent the spread of a fire, thereby maintaining a safe passage for miners needing to evacuate. The anti-static property is equally important, as the buildup of static electricity in mine environments can ignite flammable gases or dust.

Using a stopping that meets these criteria ensures compliance with safety regulations and enhances the protective measures for miners. Therefore, this choice reflects a thorough understanding of the fundamental safety requirements within Queensland mining law regarding escapeways, emphasizing both fire safety and the prevention of ignition sources in potentially hazardous environments.

The other options do not provide the necessary safety features required for a primary escapeway separation. Lightweight materials may not withstand structural demands or resist fire properly, regular timber stops lack any specific treatment for fire or static control, and easily movable stops could potentially compromise the stability and integrity of the escapeway, making them unsuitable for this critical function.
