The effect of combining tasks

Scenario #1

Our truck driver from previous scenarios puts in 500 miles per day, with no more than 11 hours driving time allowed by DOT standards, with a total of no more than 14 hours worked in a 24-hour period. Truck drivers must rest (or be off duty) for at least 10 hours for every 24-hour period. Traveling 500 miles in 11 hours means that the driver has to maintain an average of 45.5 miles per hour. Keep in mind that the driver will need to stop for various reasons, such as fuel, food, and bathroom breaks (depending on how many large quantities of coffee they drank). Also, the driver has a satellite system in the truck that monitors the miles driven, the average and specific speed, the fuel flow, and time.

Question 1. Use the Iowa Model (page 270 of the textbook) to make recommendations for improving the performance of drivers in the scenario.

(1) The effect of combining tasks – what are three examples that the driver could do to combine tasks to improve efficiency?

(2) The effect of performing particular task sequences – recommend a sequence for a series of tasks for the driver to maintain accuracy and productivity.

(3) The effect of pacing – how much time the driver spends on each task.

Question 2. Provide examples of how, as an ergonomics safety professional, you might help the driver prevent the common CTDs of low back pain, sciatica, and thoracic outlet syndrome? Think in terms of analysis and body measurements. What type of technique would you use to capture and interpret the data, based on the techniques discussed in chapter 6? Your response should be at least 150 words.

Question 3. Knowing that the driver gets paid by the mile and has to travel 500 miles per day in order to make his daily pay, list several things that drivers do that might be dangerous to themselves or others in order to make this production. These are items that we as safety professionals should be on the lookout for. Your response should be at least 150 words.
