Odor Control Safety

Safety programs set forth by the City in accordance with all Federal, State, and Local regulations will be followed by employees. Check with your immediate supervisor if you are unsure of the safety requirements necessary to perform duties in this process area. Wastewater personnel are obligated to understand and follow all confined space requirements set forth by the City.
General Safety Precautions
  • Use lockout procedures when performing maintenance on any electrical or mechanical equipment prior to servicing.
  • Use extreme caution to avoid falls while working around equipment.
  • Keep area well lit at all times when working at night or early in the morning.
  • Practice meticulous personal hygiene when work requires contract with mechanical equipment.
  • Keep unauthorized personnel away from mechanical equipment and unit processes.
  • Never remotely operate any equipment with the safety guards out of place.
Process Specific Precautions
Wastewater treatment personnel are exposed to numerous hazards on a routine basis. With good work practices and a little common sense wastewater operations and maintenance personnel can minimize the effects of these hazards. Proper personal hygiene is the first step to minimizing these hazards. The following hazards must be taken into account before working on or around any foul air treatment equipment:
  • Oxygen Deficient Atmosphere: The atmosphere in a confined space may lack sufficient oxygen. If the oxygen level is less than 19.5% a worker must not enter the space without proper ventilation or approved self contained breathing apparatus (SCBA).
  • Flammable Atmosphere: Flammable material entering the plant may vaporize and enter the foul air collection system. Care must be taken to eliminate all sources of ignition from the area. No smoking around the foul air fans, vents or compost biofilter. 
  • Toxic Atmosphere: Gases and vapors may released as the foul air reaches the foul air treatment system.The foul air system collect these gases and transfers them to the compost filter. Care must be taken when working around the foul air units.
  • Noise: Sounds under the odor control cover or while working inside of the foul air ducting may be amplified causing hearing damage. If this hazard is suspected, proper ear protection is required. This hazard also impairs others from hearing alarms or warnings. If noise is a problem, personnel should work in pairs when working in this space.
  • Slick or Wet Surfaces: The inside of the duct work sometimes contains slime or other slippery material. If entry is required, all surfaces must be hosed down completely to minimize this hazard. In addition, proper footwear must be used.
