A wastewater facility in Nebraska was interested in transitioning to a biogas to RNG facility. Typically, Glauber Equipment installs equipment in Class 1, Division 2 hazardous locations, however this facility is classified as a Class 1, Division 1 hazardous location. This distinction, established in the National Electric Code (NEC) put forth by the National Fire Protection Association (NFPA), means the area has enough flammable gases and vapors in the air to create a continuous risk of explosions or fires.
Because workers have to operate under the assumption that flammable gases and vapors are always present, they require stringent safety procedures and reliable equipment to make the site as safe as possible. This includes the need for explosion-proof equipment that can control the risk of explosions and malfunctions in the event of small electrical explosions.
