Water and wastewater facilities are among the most dangerous workplaces — H₂S kills more workers than any other toxic gas
The "silent killer" — heavier than air, accumulates in low areas. Deadens sense of smell at dangerous levels. IDLH: 100 ppm. Found in sewers, digesters, wet wells, headworks.
Explosive in 5-15% concentration range. Generated in digesters, sewers, and any anaerobic environment. Lighter than air — accumulates at ceiling level.
Biological activity consumes O₂ in confined spaces. Normal: 20.9%. Danger below 19.5%. Asphyxiation risk in manholes, tanks, and enclosed areas.
Toxic at low concentrations. Cl₂ exposure limit: 0.5 ppm TWA. Chemical storage and dosing areas require continuous monitoring.
24/7 fixed sensors at critical locations — wet wells, digesters, chemical storage, headworks. No blind spots, no missed alarms.
TWA, STEL, Ceiling, and IDLH alarm levels. Visual strobes, audible horns, and SMS/email alerts. Integration with SCADA for automatic response.
Automatic fan activation when gas levels rise. Confined space entry permit integration. Pre-entry atmosphere verification.
Fixed sensors complement personal gas detectors. Real-time location awareness. Man-down detection and emergency response coordination.
