Methane, hydrogen, sulfide, ammonia, carbon dioxide, carbon monoxide, chlorine, ozone, and other poisonous and explosive gases are produced and used in wastewater and potable water treatment facilities. Furthermore, the increased concentration of toxic chemicals and less oxygen in enclosed spaces make these environments particularly risky for employees.
NFPA 820 specifies rules for protecting wastewater treatment plants and their associated collecting systems against fire and explosive risks. New installations, extensions, and upgrades to existing facilities are all subject to the regulations. Owners utilize the requirements in a risk assessment to determine whether portions of a treatment plant are in danger of fire or other loss. Many sites require combustible gas detection, mainly for methane (CH4). Monitoring hydrogen sulfide (H2S) and oxygen (O2) is also common. The installation of a methane gas detecting station near the roof of a structure is typical. Oxygen and hydrogen sulfide detection stations offer safety in the breathing zone for personnel protection. NFPA 820 mandates alarm signaling for flammable gas detectors and ventilation.
These municipal water and wastewater customers’ monitoring safety challenges are addressed with technology from MSA.
The MSA TriGas X5000 Monitoring System is an integrated gas detection solution that assists plant operators in meeting NFPA 820 requirements. The system monitors combustible gases, hydrogen sulfide, and oxygen levels, with onboard alarming and a communication interface to plant and remote control stations.
The MSA TriGas X5000 Monitoring System assists you in complying with:
- NFPA 820: Standard for Fire Protection in Wastewater Treatment and Collection Facilities
- NFPA 497: Recommended Practice for the Classification of Flammable Liquids, Gases, or Vapors and of Hazardous (Classified) Locations for Electrical Installations in Chemical Process Areas
- NFPA 70®: National Electric Code® when standard practice dictates separation of electronics from sources of gas leaks.
The TriGas X5000 Monitoring System is specifically designed for optimum performance in high-moisture environments and typically monitors for oxygen, hydrogen sulfide, and combustible gases (methane or petroleum vapors). This sampling system can also be outfitted with the necessary options to meet the wastewater industry's NFPA 820 section 1.8 standards.
The TriGas X5000 Monitoring System builds on the successful Ultima X TriGas design. The system includes combustibles, H2S and O2 gas monitors, sample pump and end-line filter, power supply, and alarming system with buzzer and strobe light.
