    Gibbs apparatus was designed and manufacture This was followed by the Paul in 1920 and the McCaa in 1927 These early American made apparatus were designed for 2 hour use The development of self contained breathing apparatus has continued to progress through the years A number of different manufacturers are now producing apparatus that are approved to be used for periods of 2 3 and 4 hours at a time Among these apparatus commonly used for mine rescue work are the Draeger BG 174 the Aerolox and the Scott Rescue Pak III Types of SCBA a Open and Closed Circuit SCBA Self contained breathing apparatus can be divided into two main categories open circuit systems and closed circuit systems The basic difference between the two systems is this An open circuit system releases all of your exhaled air carbon dioxide to the outside atmosphere through a valve in the facepiece and supplies you with fresh air to breathe A closed circuit system does not release the exhaled air Rather it recirculates the air through the apparatus and purifies the air taking out the carbon dioxide and adding fresh oxygen to the air You are then supplied with the air that has been oxygen enriched b Primary and Auxiliary SCBA In mine rescue work apparatus are classified as being either primary or auxiliary apparatus depending on how much air or oxygen they can supply to you when you wear them Primary apparatus are apparatus that have a minimum of 2 hours service time Auxiliary apparatus are units which provide by law 30 to 60 minutes service time Primary apparatus are the standard apparatus that mine rescue teams use Part 49 of Title 30 of the Code of Federal Regulations 30 CFR specifies that rescue teams must be provided with self contained breathing apparatus that have at least a 2 hour service time and are approved under Federal guidelines Auxiliary apparatus are only acceptable for a mine rescue team member to use so long as the team member has ready access to fresh air and has at least one rescue team equipped with an approved self contained breathing apparatus of 2 hours or longer rating in reserve at the fresh air base Auxiliary apparatus may either be open or closed circuit systems Primary apparatus on the other hand are designed as closed circuit systems c Apparatus Approval In order for any self contained breathing apparatus to be used in mine rescue work the apparatus must first be approved by the Federal movement Back in 1918 the Bureau of Mines began to test and approve apparatus under Schedule 13 which established the standards for approval Today the testing of the apparatus is handled by the National Institute for Occupational Safety and Health NIOSH The apparatus approval is granted jointly by NIOSH and the Mine Safety and Health Administration MSHA IV History of mine rescue a Helmet Crews In 1910 however the U S Bureau of Mines was formed and with it came the
