My Brother's Keeper
The Shepherd System was invented over a decade ago in a garage in Midland, Texas. After losing yet another colleague, Gary Crook decided to take action to prevent future unnecessary deaths caused by H2S gas. With 30+ years of experience at all levels of the oil business, Gary knew that standard gas detection systems have a major flaw: they only warn personnel who are being exposed to gas, and those workers are expected to evacuate to a safe location. But H2S gas can easily incapacitate a worker and prevent self-evacuation. An alarm is useless if the worker is incapacitated by gas. Additional deaths can occur when co-workers attempt to rescue a downed worker without taking proper precautions to protect themselves from exposure.
To solve this problem, Gary invented a mobile gas detection system that sends H2S alarm information wirelessly to onsite and offsite personnel who can monitor ongoing activities and coordinate a safe rescue for any worker who is incapacitated by exposure to H2S or other hazardous gases. The Shepherd System catalogues all data collected from sensors, creating an extensive record of exposure levels and employees' responses which increases accountability and provides invaluable information for Health, Safety and Environment professionals and executives.
Gary called his system “Shepherd” because he believes in the age-old saying that “I am my brother’s keeper.”
As the Shepherd System evolved, Gary knew he was developing revolutionary technology, and he took steps to protect his intellectual property. In 2003 and 2004, the US and Canada granted Gary’s patents covering his basic system for remotely monitoring H2S equipment, and he subsequently received patents for unique capabilities associated with other aspects of his system. Gary refined and improved the Shepherd hardware to improve reliability and add features, such as lock-out/tag-out capability and a patented lone-worker system. The proprietary Shepherd desktop software and mobile app provide extensive flexibility and ease of use for end users.
