A BEB statement said that the decision was taken to enable fellow workers pay their respects to their deceased colleague.
An investigation into the death of the unnamed Indian national will be carried out by both the company and local authorities, it said.
Normal working hours were scheduled to resume from Wednesday morning.
“The health and safety of our workforce is something that we take very seriously and we are cooperating fully with the investigation. Our thoughts and prayers are with the worker's family and friends at this difficult time,” read the BEB statement.
Workers confirmed to Muscat Daily that they were not at work as a mark of respect for their dead colleague.
