Construction and Confined Spaces
Construction sites and civil engineering projects frequently involve work in confined or partially enclosed spaces such as shafts, pits, tunnels, and manholes. Limited ventilation, changing site conditions, and the presence of hazardous substances can lead to dangerous atmospheres. Gas detection is essential to protect workers during construction, maintenance, and inspection activities in confined spaces.
Gas monitoring in construction and confined spaces
During construction work, hazardous gases can be released from soil, groundwater, sewage systems, fuel-powered equipment, or nearby industrial infrastructure. Oxygen deficiency may occur due to displacement by inert gases or biological processes, while combustible and toxic gases can accumulate in poorly ventilated areas. Before entering confined spaces, atmosphere testing is required to verify safe conditions. Portable gas detectors with pumping capability support pre-entry testing and clearance measurements in shafts, tanks, trenches, and underground structures. During work, personal gas detectors provide continuous monitoring and alert workers to changing gas concentrations. In long-term or high-risk construction projects, fixed gas detection systems may be used to continuously monitor tunnels, underground structures, or enclosed technical areas where gas hazards are permanently present.
