Tehran, Iran—Two workers died today following a high-pressure steam explosion at a factory in Tehran. The blast occurred during routine operations, sending shockwaves through the industrial district. Emergency crews arrived shortly after the explosion to contain the resulting structural collapse.

The force of the steam release buckled interior walls and shattered equipment within the main production hall. Two individuals working near the boiler unit were killed instantly by the pressure surge. Several other staff members managed to escape the building before secondary fires could spread across the factory floor.

Firefighters worked for several hours to suppress the steam-driven blaze and ensure the facility was stable. The site remains under observation as engineers assess the integrity of the remaining walls. Authorities have ordered a temporary shutdown of the entire industrial complex to prevent further hazards.

Investigators are already looking into the maintenance history of the boiler system. Preliminary reports suggest a pressure valve failure might have triggered the catastrophic release of energy. Labor ministry officials are on-site to review the factory’s safety logs and employee training certifications.

Grieving family members gathered outside the facility gates as news of the identities of the deceased was confirmed. The provincial government has promised a thorough investigation into the cause of the explosion. Management at the factory has yet to provide a detailed account of the events preceding the blast.

Operations at the plant are suspended pending the outcome of a comprehensive forensic analysis. Experts will be checking all remaining equipment to ensure no other pressure vessels are at risk of failure. The incident is currently treated as an industrial safety violation, and further legal action may follow.

Work in the surrounding factories was also briefly paused as a precaution. The area remains a restricted zone while debris is cleared and the site is secured. Officials have not provided a timeline for when normal work can resume at the site.
