At beta distrubution a worker was injured when she tried to remove items fromt shelf and knocked a heavy box onto her foot. a week later some posters stored in tubes rolled off another and into an aisle. a second worker tripped over a tube and fell. Which of the following measures would best prevent this type of safety problem at beta?

give workers protective equipment to use when handling spills
mark dock edges with warnings
teach procedures for stacking items in straight even loads
train workers to lift with the legs and avoid twisting

All the measures mentioned would contribute to preventing safety problems at beta, but the most appropriate measure to address both scenarios described would be to train workers to lift with the legs and avoid twisting.

By providing proper training on lifting techniques, workers will learn how to handle heavy boxes and items safely, minimizing the risk of injury. This training would be especially relevant in the first scenario where a worker was injured while removing items from a shelf.

Additionally, this training would also be beneficial in the second scenario, where a worker tripped over a tube. By teaching workers how to stack items in straight and even loads, they would be less likely to create unstable piles or accidentally knock objects off shelves, reducing the risk of accidents.

Therefore, training workers to lift properly and avoid twisting would directly address the causes of the injuries in both incidents, making it the best preventive measure in this situation.

To prevent safety problems at beta, the following measures can be taken:

1. Give workers protective equipment to use when handling spills: This measure would be more relevant in situations where there is a risk of spills or hazardous materials. Although it can contribute to overall safety, it may not directly prevent the specific incidents mentioned in the scenario.

2. Mark dock edges with warnings: This measure can help prevent workers from accidentally falling off the dock or being injured by falling objects. While it addresses certain safety concerns, it may not directly prevent the incidents mentioned involving the heavy box and the rolled-off posters.

3. Teach procedures for stacking items in straight even loads: This measure directly addresses the issue of items falling or rolling off shelves. By teaching workers proper stacking techniques, the risk of objects becoming unstable and causing injuries is reduced. This measure can help prevent incidents like the heavy box falling onto someone's foot and the posters rolling off the shelves.

4. Train workers to lift with the legs and avoid twisting: This measure emphasizes proper lifting techniques to minimize the risk of injuries. It can prevent injuries caused by strains or falls resulting from incorrect lifting mechanics. However, it may not directly address the incidents involving the heavy box falling onto the worker's foot and the tube causing a worker to trip and fall.

Overall, the measure that would best prevent the specific safety problems described at beta is to teach procedures for stacking items in straight even loads. This will primarily address the incidents mentioned in the scenario. However, a combination of measures can be adopted to further enhance overall workplace safety.

To determine the best measure to prevent safety problems at beta, we can analyze each option and evaluate its potential effectiveness:

1. Give workers protective equipment to use when handling spills: This measure would be most suitable for situations involving spills or hazardous materials. It may not directly address the issue of heavy boxes falling or tubes rolling off shelves, so it might not be the most effective solution in this context.

2. Mark dock edges with warnings: This measure could help prevent accidents caused by workers falling off docks or tripping near edges. While it may be a helpful safety measure, it does not directly address the specific incidents mentioned, such as heavy boxes falling or tubes rolling off shelves.

3. Teach procedures for stacking items in straight even loads: This measure specifically targets the issue of heavy boxes falling. By training workers on proper stacking techniques, it reduces the risks associated with unstable piles of items. This preventive measure may help to avoid future accidents.

4. Train workers to lift with the legs and avoid twisting: This measure addresses the risk of workers getting injured while lifting heavy objects, such as the heavy box that fell on the first worker's foot. Proper lifting techniques focused on bending the knees and using the legs can significantly reduce the chance of injuries. However, this measure might not directly prevent incidents related to tubes rolling off shelves.

Considering the given incidents and their causes, the best measure to prevent this type of safety problem at beta would be to teach procedures for stacking items in straight even loads. By ensuring that items are stacked securely and uniformly, the risk of heavy boxes falling and causing injuries can be reduced.
