At MDC Systems, Inc., we help commercial and industrial facilities strengthen gas detection programs with reliable, accurate, and application-specific monitoring solutions. A photoionization detector is a valuable tool for identifying volatile organic compounds, commonly referred to as VOCs, and other hazardous vapors that may not be detected effectively by standard gas detection methods. When properly

Understanding OSHA PEL requirements is essential for any facility where hazardous gases may be present. In commercial, industrial, laboratory, manufacturing, semiconductor, wastewater, energy, and specialty process environments, gas exposure can create serious risks for employees, contractors, visitors, equipment, and operations. Permissible Exposure Limits, commonly called PELs, are regulatory exposure limits established by the Occupational Safety

Confined spaces can present serious hazards, especially when oxygen levels are unsafe or toxic and combustible gases are present. That is why selecting the right gas detection devices for confined space entry is a critical part of protecting workers, maintaining compliance, and reducing operational risk. Whether the confined space is a tank, vault, pit, tunnel,

If you are responsible for facility safety, compliance, operations, or maintenance, you may have asked: What does LEL stand for in gas detection? LEL stands for Lower Explosive Limit, which is the minimum concentration of a combustible gas or vapor in air that can ignite when exposed to an ignition source. In practical terms, LEL
