This is my Dad Paul. He works at BSL as a production technician. There are two people in a team, one being on the floor and the other in a crane. The floor operator guides the crane operator as to where the large carbon anode blocks have to be taken out and replaced. The floor operator opens to hoods of the cell by hand so the crane can reach the carbon anode block. After the block is replaced the crane covers the anode block with a powder called bath, the person on the floor then closes the hoods and wipes any excess bath by hand into a grate. Electricity is then pumped through the cell which now contains alumina and the anodes, with the addition of electricity molten aluminium is formed. This process allows for one team to repeat it on average 40 times per shift. The temperature in the cells reach 980 degrees Celsius resulting in the production floor temperature being around 55 degrees Celsius.
As the temperature of the floor is so hot there is an OHS requirement of a break every 45 minutes so the workers can get a drink and rehydrate. Dehydration can occur very quickly if it is not addressed. PPE has to be worn at all times when on the production floor due to the workers opening the hoods which expose them to temperatures of 980 degrees Celsius. the acquisition of a crane licence is required before a worker can operate a crane as improper use can end in harm or death of workers on the floor or breaking the crane. Workers have to always exercise caution as there are hazards everywhere.
