Manual material handling or MMH is the process of manipulating or moving materials using labor. MMH includes pushing, pulling, lifting, retrieving, controlling, loading and holding. Manual material handling (MMH) means moving or manipulating things by lifting, lowering, pushing, pulling, transporting, holding, or holding. MMH is also the most common cause of occupational fatigue, low back pain and lower back injuries.
These are double-ended forks with wheels, attached to a lever that raises the forks when they are pumped to lift the pallets for transport. They can be used to move pallets full of products or materials. Here, the designs were evaluated with one and two hands. The main sources of hand and finger injuries included various metallic materials (tubes, wires, protectors) and hand tools.
Manual material handling, machine maintenance and repair, and the use of hand tools were the most common activities associated with hand and finger injuries. Sprains or strains (49.1%, 816 injuries per year) are the main type of NFDL injury in mining due to material handling, with fractures, chips (13.8%, 2292 injuries per year) in second place and, thirdly, cuts, lacerations or punctures (11%, 1829 injuries per year). Work practice guide for manual lifting This report provides quantitative recommendations on the weight, size, location and frequency of safely handling the material of the load. In addition, engineering guidelines are provided for the design of workplaces where manual material handling is performed.
Eliminating physical demand from manual handling tasks is key to minimizing risk and involves the use of equipment that reduces or eliminates recurring excessive forces and uncomfortable postures for operators during work. Manual material handling (MMH) is the process of routinely moving and manipulating objects by transporting, holding, lifting, pulling, pushing and tilting. In addition, publications are available with recommendations to reduce the risk of injury associated with manual material handling. The NIOSH Lifting Equation mobile application, NLE Calc, calculates the overall hazard index for single and multiple manual lifting tasks.
Identify 26%, prioritize ESG risks and opportunities with materiality assessments that are part of the VelocityEHS ESG solution. Research studies have been conducted to examine the impact of manual material handling when adopting restricted postures, when working on workstations of different heights, and when performing repetitive stacking tasks. We currently have an internal project that focuses on the manual handling of materials specifically related to hand and finger injuries and on the application of exoskeletons to mining. Ergonomic guidelines for material handling This booklet will help you recognize the high-risk work tasks of MMH and choose effective solutions to reduce physical demands.
Solutions to prevent injuries caused by material handling in underground coal mines This article describes the development of three mechanical methods (the mobile manipulator, the elevator installed in the mine, and a cable handling system) for loading, unloading, moving supplies and materials and handling dragged cables. Carts have flat surfaces, transport containers or shelves that operators push or pull to transport materials.
