" when the pneumatic clamshell closed.."

 

The use of hoppers in our workplaces is a necessity. They come in all sizes and shapes and for the most part hazards associated with them are not even a consideration. Here is a recent incident that highlights a hidden hazard that might be present in many workplaces.

(Aluminium company name omitted) confirmed the death at its site off (location omitted).

It happened around 2:30 p.m., (local) Fire & Rescue and Life EMS told (local tv news channel). According to the (name omitted) Occupational Safety and Health Administration, the worker — a 43-year-old maintenance technician — was welding inside a pneumatically powered scrap chute when the pneumatic clamshell closed.

Co-workers attempted CPR and used an AED before the arrival of first responders, but a doctor on scene pronounced the employee dead.

"Everyone at (aluminium company) is deeply saddened and our thoughts are with the family, in addition to the welfare of all of our employees," a (aluminium company) spokesperson said in a statement.

The spokesperson said (aluminium company) has made counseling available to its employees.

We offer our sincere condolences to the deceased worker’s family, friends, and colleagues. The news media articles state that the worker was welding inside a chute when the pneumatic doors closed unexpectedly. We do not know if the worker performed safe isolation/lock out tag out before the task.

We post this tragedy to bring awareness to a hazard hidden in your workplace. If you do have chutes or any machinery that has pneumatic or hydraulics that a worker has to enter. In addition to lockout tagout/safe isolation a last-ditch device (ldd) can be installed. The LDD is a customed device that will physically prevent the machinery from moving if all safety measures fail and the pneumatic/hydraulic activate. We recommend using old overhead crane rails. Please note this is not a replacement of LOTO or safe isolation.

We will update this story when further information is available.
