Which type of equipment should be used for breathing air only in emergencies?

The use of oxygen breathing apparatus is specifically designed for situations where the air quality is compromised, such as during firefighting or in environments with insufficient oxygen levels. This equipment is meant for emergency situations, providing a safe supply of oxygen to the user while isolating them from harmful airborne substances.

In emergencies, the oxygen breathing apparatus allows individuals to perform critical tasks without the risk of suffocation or inhalation of toxic fumes, making it essential for maintaining safety in hazardous environments. Its design ensures that users can effectively breathe and carry out operations until they can retreat to a safe atmosphere or receive assistance.

Standard breathing masks and gas masks are generally used for specific scenarios, such as protection from particulate matter or chemical agents, and may not provide the same level of pure oxygen supply. Regular oxygen tanks, while capable of supplying oxygen, are not specialized gear intended solely for emergency responses, and they can pose risks if not managed properly. Therefore, the oxygen breathing apparatus is indeed the most appropriate choice for emergency breathing needs in potentially dangerous situations.
