Instead of lifting and pouring from the drum, insert a siphon or a pump. Increase the size of the container or the weight of the load so that it is too large to handle manually. Use a hook for light-weight containers to reduce your reach. Use a drum dolly. Use a cart or platform truck. Use a portable scissors lift. Use a hand truck.
Examples include twisting, reaching, pulling, lifting, bending, or any other posture that can cause pain when sustained for a prolonged period. [2] Examples of awkward postures include: Bending or twisting the torso while lifting heavy objects: This can place excessive stress on the back muscles and spine.
The NIOSH lifting equation is a tool (now application) that can be used by health and safety professionals to assess employees who are exposed to manual lifting or handling of materials. [7] The NIOSH lifting equation is a mathematical calculation which calculates the Recommended Weight Limit (RWL) using a series of tables, variables, and ...
After that the patient is carefully rolled in the desired direction without twisting or bending the body. Log-rolling. Typically logrolling into a supine position is used for transport of a casualty. Other cases include logrolling on a side, e.g., to facilitate vomiting., [3] or from side to side, for medical examination. [4]
Hogging is the stress a ship's hull or keel experiences that causes the center or the keel to bend upward. Sagging is the stress a ship's hull or keel is placed under when a wave is the same length as the ship and the ship is in the trough of two waves.
Plate pinches Place the weight plate on the ground standing upright on its side. Bend down and hold the plate using a pinch grip between your fingers and thumbs only. The plate shouldn't touch the palm of your hand. Straighten up and lift the plate using the pinch grip, up to your chest, and then slowly place it back on the ground.
Strains and sprains to the back muscles can be caused by improper movements while lifting heavy loads, overuse of a muscle, sudden forceful movements, or direct trauma. [8] Herniated discs are associated with age-related degeneration, trauma such as a fall or car accident, and bending or twisting while lifting heavy weights. [9]
Fig. 1: Critical stress vs slenderness ratio for steel, for E = 200 GPa, yield strength = 240 MPa.. Euler's critical load or Euler's buckling load is the compressive load at which a slender column will suddenly bend or buckle.
