Structure re-modification The redesigning of tools or workstations may be necessary in preventing MSIs. Modification of the design may reduce awkward wrist positions and minimize the effects of repetitive motions (Canadian Centre for Occupational Health and Safety, 2015). Proper designing of hand tools, minimizes awkward positioning of the hand and wrist when the task involves repetitive movement (Canadian Centre for Occupational Health and Safety, 2015).
Other engineering controls include the following:
a. A lever to lift and transport the heavy timber woods
b. A …show more content…
Total number of hours per day spent lifting = 1hr to 2 hrs
The results showed that the actual weight lifted (30lbs) is less than the weight limit calculated. Hence the lift/lower task has a low risk of MSI hazard. This implied that the controls were effective and no further controls are needed.
The below is the computed results of the hazard assessment.
Based on the results of the hazard re-assessment after the controls were put in place, the following recommendations will be made.
1. To ensure that the maximum weight of log to be lifted by any employee at the company is 30lbs
2. All manual lifting should be performed as close to the feet as possible (zero inches to the feet)
3. Workers should comply with safe work practices for lifting and ensure that during lifts, sideways twisting is avoided
4. The maximum lift or lowering per minute should be 1 lift/lower every 4-5 minutes
5. Shift rotation for the lifting of the timber wood should ensure that the total time spent daily in lifting does not exceed 2 hours per worker. This will ensure that each worker does the physically demanding task of lifting and not limited to only one worker.
