A recent accident at a dairy facility in India's Visakhapatnam district led to the deaths of several engineers who were performing equipment maintenance, reported The New Indian Express. The explosion was caused by a boiler fire which led to an electromechanical failure, killing the three contract workers who were installing new refrigeration machinery. Truth Dive also reported that four other workers were injured in the explosion and taken to a local hospital for treatment.
The Heritage Dairy Plant, part of Heritage Foods India Ltd., is located in the Bayyavaram village in Kasimkota mandal in the Visakhapatnam district. The dairy company attributes the fire to a prob?lem that arose during the installation of the new machinery, but police suspect there may have been another cause for the fire. Kasimkota p?olice inspector Govinda Rao told The New Indian Express that the accident may have been caused because of an ammonia leak or other pre-existing technical problem. The police will conduct an investigation to determine the cause of the fire.
"The workers were engaged in insulation work when the unfortunate accident happened," explained the dairy in a press release about the incident. "It is the first accident in 21 years and the management deeply regrets the incident and conveys condolences to the bereaved families."
The Hindu Business Online reported that this is the second plant accident in this part of the country, and that another accident recently occurred at the Visakhapatnam Steel Plant. Five workers were injured in a blast that was caused by slag coming into contact with water in a blast furnace because a power supply failed, explained the news source. Four of the workers are currently being treated in a local hospital, but are expected to recover from their injuries.
Both of these industrial accidents underscore the need for plants to take equipment condition monitoring seriously. If plant managers use predictive maintenance, then they are more likely to identify equipment problems or potential failures before they occur.
