SANTA ANA, Calif.—Two supervisors have pleaded no contest to felony charges in the deaths of two workers killed by a water heater explosion at a Southern California plastics manufacturing plant.

The Orange County Register ( reports that plant manager Carl E. Richardson and maintenance supervisor Roy Faulkinbury entered the pleas Friday, agreeing to pay $450,000 to the victims' families and perform 250 hours of community service.

The charges stemmed from a 2009 explosion at Solus Industrial Innovations in Rancho Santa Margarita that killed 51-year-old Jose Jimenez of Garden Grove and 34-year-old Isidro Echeverria of Oceanside. Two other workers were injured.

The supervisors were charged with two violations of California's labor code. Prosecutors say they decided to buy a residential water heater instead of an industrial one when the plant opened in 2007.
