In 1969, Samuel Shearer founded CSE Corporation as an environmental research company servicing the coal industry. In the mid-1970s, CSE developed the first of many noxious gas detection devices and quickly became a leader in air-quality monitoring systems. In the early 1980s, CSE introduced the first available one-hour oxygen Self-Contained Self Rescuer (SCSR) when federal regulations began requiring underground miners have access to a 60-minute breathing apparatus. CSE next introduced the first belt-wearable SCSR. CSE has since become a world leader in SCSR development and technology, earning some of the most prestigious awards available in the industry. For example R&D Magazine awarded one of its prestigious R&D 100 awards to CSE for producing one of the most technologically advanced new products in the world.
