Hazardous Gas Monitoring involves the detection and measurement of harmful gases in the environment to ensure safety in workplaces and public areas. This process uses specialized equipment, such as gas detectors and sensors, to identify the presence of gases like carbon monoxide, methane, and hydrogen sulfide, which can pose serious health risks. Regular monitoring is essential in industries such as oil and gas, chemical manufacturing, and mining, where exposure to toxic gases can occur. By implementing effective monitoring systems, organizations can take timely action to protect workers and the surrounding community from potential hazards.
