No less than 116 risks of fall avoided at Electrolysis
In 2006, a budget of $1.8 million was approved to modify the eight service machines at Electrolysis (MSE) at the Deschambault Smelter to help prevent the risk of falls which, due to the proximity of molten metal, could be fatal. The proposed solutions were vetted from an engineering standpoint in 2007 so that the upgrades could be made to the MSE in 2008. Effective coordination between the team from Hatch and Alcoa’s bridge crane crew enabled cost savings of over $500,000.
Each of the eight machines is now equipped with measures to protect against 17 different types of falls, for a total of 116 risks eliminated. The measures applied were:
addition of an access ladder with a safety bow at the beam
removal of the two existing yielding guards above the MSE
addition of handrails and protective grids around the access ladders above the MSE
installation of aluminum plaques, also at the top of the MSE
installation of a footwalk and a staircase to access the MSE beam
addition of a protective grid around the staircase to the MSE tool holder
addition of a locking mechanism at the trapdoors to the main beam
addition of bolted guards around the long travel motors
the door to the main beam was raised
addition of a platform and guiderail to provide access to hoist no. 29
addition of a ladder to access the tool holder
removal of the wood ladders and addition of retractable cords
addition of a locking system on the trapdoors to the ladders
addition of fall-protection rails on the roof cabs of the MSE
replacement of the lifting eyes
installation of a footwalk and an anti-fall system
These significant improvements to the MSE will facilitate maintenance while making the environment safer for anyone working on the machines, whether mechanics, electricians or the industrial cleaning crew. Congratulations to all those who participated in this project initiated by the Fall Prevention team.
