In manufacturing plants, offshore drilling platforms, water treatment facilities, and other sites, maintenance technicians and other workers spend much of their time in confined spaces. Often areas where equipment repairs, installations, and troubleshooting take place, confined spaces are usually some of the most difficult areas to monitor for dangerous gas buildups. However, as monitoring systems have become more advanced over the years, this task has become much easier. Since there are guidelines set forth by OSHA regarding safe oxygen levels within confined spaces, facilities are required to have systems in place that can keep workers as safe as possible. To learn more about how oxygen gas detection systems accomplish this, here are some important details to consider.
