3.ERGONOMICS AND TRUCK DRIVERS/OPERATORS
4.LONG TERM SITTING
This paper will show an ergonomics assessment for truck drivers and operators. Ergonomics improves low back pain, shoulder pain, or problems with hands and wrists for many truck drivers. Ergonomists and Human factors specialist noticed many drivers reporting pain after operating a particular vehicle. Some reports includes long hours of driving, loading and unloading cargo, asymmetrical schedules, related with work-related injury and poor health status. Introduction
Ergonomics is the science of fitting the workplace conditions and job demands to the capabilities of the working population. When goal of ergonomics is applied correctly in the work environment, visual and musculoskeletal discomfort and fatigue are reduced significantly. Truck drivers and operators spend a significant proportion sitting for extend periods of time and increasing demand for comfort. There are a variety of reasons for ergonomics to improve driving comfort conditions in vehicles. Ergonomics assessment for truck drivers and operators report shows an incidence of fatigue connected problems in drivers and their relations with near miss and accident experience as well as work and organizational factors. The results were interpreted in the overarching principles of risk assessment and risk control. Driving a vehicle is a major activity of a truck driver or operator. Truck drivers, bus drivers, ambulance drivers, heavy equipment operators, and other drivers that drive for long periods of time on a daily basis are at risk. These drivers are exposed to a mixture of vibration for long periods of time. By being expose can lead many drivers to experience low back pain, shoulder pain, problems with hands or wrist possibly leading to chronic back pain in later months or years. Symptoms that are felt by truck drivers are from exposure to the ergonomic risk factors of driving. “NIOSH characteristics of a truck driver’s job, including long hours of driving, loading and unloading cargo, irregular schedules, a sedentary lifestyle, and the nature of drivers’ food choices on the road, are associated with work-related injury and poor health status.

ERGONOMICS AND TRUCK DRIVERS/OPERATORS
Many drivers experience a fatigue while driving during the day and along with shifts rotation. There is a significant associations found between fatigue experiences and driver and management systems route scheduling. The quantitative shared with qualitative information recommended more flexible approaches to administration the scheduling deliveries assisting drivers in managing their fatigue issues by taking frequently breaks during extended drives. Many truck and delivery companies noticed many drivers reporting and some reported discomfort in vehicle seat after operating a particular vehicle. The objective measurement of truck driver’s discomfort should be approach by the measurement of pressure, position and physiological at the truck driver’s or operator’s seat. Seat adjustment is a key feature of the delivery vehicle. Ergonomics assessment for truck drivers and operators showed drivers sitting in a forward-facing seat while they looked out a side window to an operating arm, so they sat in a twisted and side bending posture; and the hand furthest from the window used a joystick and other controls positioned low to the seat, and next to their hip, with the wrist often in a bent, extended posture. Chronic back and neck injuries from driving are caused by two main risks. The two major factors are sitting for extend periods of time and whole-body vibration.
