Water & Wastewater Treatment

The water and wastewater processes are complex and present a variety of hazardous gases throughout the treatment processes. Obviously, every scenario can not be covered here but the common dangers will be touched upon.

Wastewater Treatment –

Carbon Monoxide, Carbon Dioxide, Chlorine, Methane (both oxygen depleting and flammable), Oxygen depletion, Hydrogen Sulfide and more can occur in many areas. These include, but are not limited to the treatment plant, sewers, sludge tanks, pumping stations, aeration tanks and deodorizing plants. Obviously, it depends on the setup, but the many hazards are there from beginning to end. ALL workers should Bump Test their Gas Detection Units (GDU) as they are powered up for use. It is not required but it is smart. A bump test will spray gases across the sensors of the GDU letting you know that all sensors and alarms are functioning properly. Sensors can go bad at any time and that is why we recommend exceeding OSHA’s recommended “before each day’s use” suggestion. GDU’s get a workout in this industry because of the heavy use. Rolling the dice can be deadly and mitigating that danger takes less than 30 seconds!

Clean Water Facilities –

Ammonia, Sulfur Dioxide, Chlorine, Chlorine Dioxide and others can be found in areas such as; ozone generators, gas storage areas, chemical treatment areas and chlorine gas application and disinfecting areas. Most facilities use a chlorine gas (shipped in) or process Sodium Hypochlorite on site. In either scenario, harmful gases are produced as a reaction to the additives. Every step of the aforementioned processes, from chlorination to the final product of potable water, presents its own set of risks and fixed and portable GDU’s should be used throughout.

Gasco’s precision calibration gases should be used to keep fixed and portable units from drifting. Gasco bump gas cylinders should test portable systems EVERY TIME they are powered up for use.

Bump tests SAVE LIVES!
