the Truck Driver
In this scenario, Ben is a truck driver who has been
driving for at least 15 years and is now complaining of right shoulder and neck
pain. Ben is 45 years old, 6 feet tall, and weighs 220 pounds. Ben has been
driving a semi-truck, which has a handle for climbing into the truck and it is
mounted on the side of the cab. The trailers Ben usually hauls are box
trailers, and Ben has to climb into and out of the trailer multiple times per
day using the handle on the rear of the trailer.
Our truck driver from the scenario
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 to make
recommendations for improving the performance of drivers in the scenario.
(A) The effect of combining tasks – what are three
examples that the driver could do to combine tasks to improve efficiency?
(B) The effect of performing particular task
sequences – recommend a sequence for a series of tasks for the driver to
maintain accuracy and productivity.
(C) 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
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.
