Workplace health, safety and wellbeing for Blow Moulding Units: heavy drums, hot parisons and tired nights
Blow moulding adds hot parison, compressed air, chilled water and heavy drums to the usual press risks. Safety here is about manual handling, burns and quiet attention on long cycles.

Large drum lines need people to lift, carry and stack heavy parts, often after trimming with a knife. Hands get cut, backs get strained and fingers are caught near the mould. A hot parison can burn a hand, and a failed air line can whip. At night, long cycles lull operators, and a person who is tired reaches into the mould area before the machine has fully stopped.
Good practice begins with a floor walk to mark pinch points, hot zones, air and water lines, and the trim bench. Heavy items get lifting aids and a two-person rule. Knife use is covered by a safe method and proper tool storage. Operators are taught to stop the machine before reaching in. Night shifts get rest breaks and a supervisor round, and complaints of aches or burns are noted and acted on.
How to set it up
1. Walk each line and mark the hazards
Look at the mould area, parison zone, air hoses, cooling water lines, the trim bench and the pack-out path. Ask operators where they have been hurt or nearly hurt.
2. Set a lifting rule for drums and cans
Agree weights at which a lifting aid or two people are needed. Place trolleys and stackers where they are used. Check that the path from machine to pack is clear.
3. Write a safe knife and trim method
Where deflashing uses blades, define the tool, the cut direction, and a place to leave it. Replace damaged tools. Teach new operators on the bench with a trainer.
4. Check air and water lines on a schedule
A simple round to look for worn hoses and leaks. Report faults in the shift log and fix them quickly. See workplace health, safety and wellbeing.
5. Protect night shift attention
Plan breaks, add a supervisor round and avoid putting the most tiring job on the same person all night. Rotate tasks within the shift where possible.
Check these first
Before changing anything, find out what is true today. These take an afternoon and use your own records.
- Count the cuts, burns and strains recorded in the last three months, split by task.
- Walk the drum line and note the heaviest item moved by hand.
- Check the date of the last inspection of air hoses and water lines.
- Ask a night operator when they last felt close to an accident.

Questions owners ask
Usually cuts at the trim bench and reaching into the mould area before the cycle ends. Both come from habit and speed. A clear method, sharp but safe tools and a firm stop-first rule reduce them without slowing the line much.
A short sheet at each machine, with pictures, helps new operators and reminds experienced ones. Keep it to one page, in the language the team reads, and update it when the process changes. Ask operators to help write it.
Shortcuts grow when supervision is absent and targets are tight. Have the supervisor walk the line at set times, keep targets realistic for the shift, and treat a reported near miss as useful information, not a fault.
