Self-Rescue Respirator

Human: Carbon monoxide is one of the dangers that coal miners may face. This gas forms during incomplete combustion of carbon-rich materials. Carbon monoxide is highly flammable, explosive, and toxic. Rescue teams used Self-Rescue Respirators to breathe in oxygen and protect themselves from carbon monoxide while saving miners trapped underground. The respirator consists of a small oxygen tank and a flexible mouthpiece to shield the nose and mouth. To put on the respirator, one must break the red strap and place it over the face. With this respirator, a person can survive for up to 20-30 minutes in an area with hazardous air (toxic gases). These respirators were used from 1950 until the 1970s, when coal mines in Limburg ceased operation. The original can be found at the Dutch Mining Museum (Netherlands Mijnmuseum) in Heerlen.
