Case Study - Powder bag handling

Note: Contains public sector information published by the Health and Safety Executive and licensed under the Open Government Licence’.

Task

In the powder handling department of a yellow fat spreads manufacturer, 25 kg bags of powdered milk-based ingredients were delivered on a pallet. An operator carried the bags, at a rate of 12–16 per hour, seven steps up to a platform containing a hopper

Problems

* Operators were suffering from muscle strains/sprains and tiredness.

* Occasionally bags would be dropped resulting in wastage.

*There was a possibility that operators could slip or trip when transporting the bags.

* The operators had to stoop to reach bags from the lower layers of the pallet.

* The operators were holding loads away from the body when lifting bags from the middle of the pallet.

* Complaints had been received from the workforce.

* The operators were spending many days off ill.

* Compensation claims had been received.

Finding solutions

The company built a platform and associated racking on a level with the hopper, on which the full pallets could be placed by a fork-lift truck. They also installed a vacuum lifter, which was used to transfer the bags from the pallet to the hopper

Results

* The manual handling associated with the task was reduced.
* No further complaints were received from the workforce.
* Operators no longer suffer from muscle strains/sprains and tiredness.
* There was a reduction in dropped bags and wastage.
* The operators no longer had to stoop to reach bags from the lower layers of the pallet or hold loads away from the body when lifting bags from the middle of the pallet.
* No further compensation claims had been received.
* There was an increase in efficiency, productivity and quality.

Expanding on the solutions provided

Pallet gate

The installation of a pallet landing platform will need to comply with the latest standard ISO 14122-3:2016 for fall protection on raised platforms of 500 mm height or over.

The Sigma universal safety pallet gate is ideal for this application as the design can be adapted for use with a vacuum lifter. allowing the lifter clear access over the entire pallet and the compact side frames allow good access on three sides.
