Safety on the Plastics Processing Floor: Design Out the Risk
Safety in plastics processing is often associated with guarding, PPE, lockout/tagout and operator training. All are essential – but some of the biggest opportunities to improve safety come from looking at how work is actually performed on the production floor.
Every time an operator has to lift, reach, climb, disconnect a hose, move a mold or manually handle a repetitive task, there is potential risk.
The question should be: Can we engineer some of that risk out of the process?
Mold Changes – More Than Moving the Mold
Mold changes combine several potential hazards: heavy loads, overhead lifting, pinch points, hydraulic connections, electrical connections and water lines.
Anything that reduces the amount of manual handling deserves consideration. Mold carts, roller systems, quick clamping systems, magnetic platens and standardized connections can help make mold changes more controlled and repeatable.
For example, EAS Change Systems offers technologies for mold handling, movement, clamping and connection that can reduce the amount of manual intervention required during a mold change.
The objective isn’t simply a faster mold change. It’s reducing the number of opportunities for someone to lift, push, pull, reach or place themselves near a heavy or moving load.
Don’t Forget the Water
Cooling hoses are easy to overlook, but they’re an everyday part of the molding environment.
Disconnected hoses can release water onto the floor, creating slip hazards. Hot water can create an additional risk, while multiple hoses around the machine can become trip hazards.
Better hose routing, shutoff systems, organized connections and manifolds can help keep water where it belongs while also making mold changes cleaner and more efficient.
Products such as Smartflow manifolds and SWAP Valves are examples of how mold-water connections can be better organized and controlled, helping reduce the potential for water spillage during mold changes and routine operation.
Good housekeeping is important – but preventing the spill in the first place is better.
Automation Can Be a Safety Tool
Automation is usually justified through labor savings, cycle consistency or productivity. But it can also remove people from repetitive or potentially hazardous tasks.
Consider the number of times an operator may manually remove, lift, orient, inspect, trim, stack or package a part during a shift.
Even relatively light components can create ergonomic concerns when the same movement is repeated hundreds or thousands of times.
Robots, conveyors and other automated handling systems can reduce repetitive lifting and reaching while limiting the need for operators to interact directly with moving machinery.
Look Beyond the Machine Guard
A guarded molding machine may be safe during automatic operation, but what happens around it?
Where does the operator stand? How are parts moved? Where are hoses and cables routed? How is scrap handled? How are material containers changed? How often does someone need to climb, bend or reach?
Many safety improvements come from examining these routine activities rather than focusing only on the primary machine.
Safety and Productivity Often Support Each Other
Interestingly, many changes that improve safety can also improve productivity.
Better mold handling can shorten changeovers. Organized water connections can reduce setup time. Automation can improve consistency. Better material and part handling can reduce unnecessary movement.
Safety doesn’t always have to be viewed as something added to the process.
Sometimes the best approach is to design the process so the risk isn’t there in the first place.
The next time you walk through your production floor, don’t just ask:
“Is this operation safe?”
Ask:
“Where are people still lifting, reaching, climbing, pulling, carrying or working around something that could be engineered out of the process?”
That question may identify opportunities to make the production floor both safer and more productive.
