Question
Physical workload is quite common in Tanzania, state the factors that need to be considered in suggesting an appropriate method of manual material handling, how would you measure these factors and evaluate the lifting performance.
Solution
When suggesting an appropriate method of manual material handling in Tanzania, several factors need to be considered:
-
The nature of the material: This includes the weight, size, shape, and fragility of the material. These factors can be measured using appropriate tools such as scales for weight, measuring tapes for size, and visual inspection for shape and fragility.
-
The task: This includes the distance to be covered, the height at which the material is to be lifted, and the frequency of the task. These can be measured using a stopwatch for time, a measuring tape for distance and height, and a tally counter for frequency.
-
The environment: This includes the working conditions such as temperature, humidity, lighting, and noise. These can be measured using appropriate tools such as a thermometer for temperature, a hygrometer for humidity, a light meter for lighting, and a sound level meter for noise.
-
The individual: This includes the worker's physical condition, age, gender, and training. These can be measured using a medical examination for physical condition, a birth certificate for age, visual inspection for gender, and training records for training.
To evaluate the lifting performance, you can use a combination of direct observation, video recording, and the use of wearable technology to measure the biomechanics of the lift. You can also use self-report measures such as questionnaires and interviews to gather information on the worker's perception of the task. The data collected can then be analyzed to identify any potential risks and to suggest improvements to the lifting method.
