The cognitive load in assessing the way the items are organized and how each of these items are labeled is high because many of the price labels are not aligned to the designated product in the shelf. Some price labels are also too close to each other that it may become a visual noise to some. This would reduce the workers productivity in organizing the items and its price labels because this would demand a huge amount of working memory to the workers doing the activity. The workers should align the price labels to its designated items on the shelf and they should make sure that there is enough distance between the price labels to reduce the visual noise. It would also reduce the cognitive load on the sensory memories of both workers and customers when organizing or shopping.One of the most commonly used appliance that has a big amount of cognitive load when operating In the rula or reba, the activity to be assessed is when the workers are serving the customers at the cashier.In the reba, because the screen where they punch the orders is placed at a high place and the cashier table is low, it would require the workers to raise and abduct their arm. This would produce an upper arm score of +4 and a lower arm score of +2. Because of how they receive the customer’s products to buy, the wrist score would be a +2. Since most of the products don’t have handles but are still easy to carry, the coupling score of fair would be a +1. Because of the setup in the cashier, where there are products at the back, the sides, and below the cashier table, the setup would cause trunk twist, and neck, trunk, and leg bending which would give both the neck and leg score a +2 and the trunk score a +4. Using the reba in assessing the two posture scores, the results showed a …. And the reba score says that ….
To improve the current setup of the workers that would reduce the reba score, it is suggested that the setup of the cashier place would be a table high enough to reduce the lower arm score and to lower the screen enough to reduce the upper arm score. The other products that are placed under the cashier table should be placed above the table somewhere so that neck and trunk bending would be reduced.NIOSHWidth of crate 17 inD 41 inO 13inConsidering the highest point of stacking of the bottle crates, the vertical distance of the destination of the lifting would be 41in and would start at a vertical distance of 13in because of the handle of the crate being in that place. The average weight of an empty glass bottle is 170g or 0.374 lbs. the sagittal width of the crates are approximately 17in. In assessing the lifting activity with the NIOSH Lifting Equation, the recommended weight limit would be 25lbs. if each crate would be able to hold 24 bottles each, the lifting activity is accepted by the OSHA Standards as long as the bottle is empty.
