Chlorine Gas (Cl₂)
CAS Number:
7782-50-5
Chlorine gas (Cl2) is a toxic, yellow-green gas with a pungent odor commonly encountered in water treatment facilities, swimming pools, chemical manufacturing, and industrial bleaching operations. Exposure to chlorine gas can cause severe respiratory irritation, coughing, chest pain, and at high concentrations, pulmonary edema and death. OSHA has established a permissible exposure limit (PEL) of 1 ppm as an 8-hour time-weighted average. Real-time monitoring with portable gas detectors is essential for worker safety in environments where chlorine gas may be present, particularly during maintenance, cleaning, or emergency response situations.
Chlorine (Cl2) monitoring is important anywhere leaks or releases can create a fast-acting respiratory hazard, especially in water treatment and chemical handling areas. Rent chlorine-capable gas monitors from RAECO Rents for wastewater and drinking water facilities, pool maintenance, chemical manufacturing, and emergency response readiness. Gas monitors are bump tested or span calibrated on the day of shipment, and our team can help confirm the right monitor, sensor range, and alarm settings, with fast turnaround and phone support so you can get reliable field readings quickly.
