"explosion in the scrap melting boiler..."

 

Every plant (including smelters) that processes molten metal is currently using scrap or investigating incorporating scrap into their production. This recent explosion highlights this growing hazard associated with scrap.

Explosion in the industrial zone: 1 worker injured

The explosion in a factory operating in the (location name omitted), caused panic. In the explosion in the scrap melting boiler, a worker was slightly injured, while the exterior cladding of the factory exploded.

Explosion in Scrap Melting Boiler

According to reports, the incident took place at an aluminum factory in the (name omitted). There was an explosion in the scrap melting boiler for an undetermined reason. As a result of the explosion, heavy smoke was covered inside the factory, and a huge noise was heard in the vicinity.

Fire and Health Teams Shipped to the Region

Upon notification, several fire brigades and paramedics were dispatched to the scene. The first response was made by the paramedics to the worker who was slightly injured in the explosion at the scene.

Investigation Launched

With the intensity of the explosion, the facade cladding of the factory was dismantled and scattered around the environment with a great noise. While the teams were conducting investigations at the factory site, the report on the cause of the explosion was filed.

We pray that the injured worker recovers fully from their injuries. When we can meet the plant owner. We would mention that they were lucky in terms of damage. We have reported on numerous incidents where scrap has caused catastrophic explosions destroying plants and killing workers.

In addition, the design of the building allowed the explosion to escape. If the building was constructed with concrete panels the shockwaves would have revibrated back into the plant causing more injuries and possible fatalities.

All indications are this workplace charged scrap that was wet, contaminated, closed end (eg., pipe, tank), etc.. It is unknown if the plant shreds their scrap or not prior to charging.

Looking at the above photo, the scrap grade is low. Please note there is nothing wrong with low grade scrap. Low grade scrap just has more hazards that a workplace has to inspect and remove prior to charging.

The Aluminium Association (USA) has a great reference documents on scrap safety. They can be found here.
