AECOM 4.2.2 Mechanical equipment or assistance such as hand carts, dollies, carts, come-alongs, conveyors, rollers, or if appropriate, pallet jacks, skid steers, or telehandlers, are preferable to be used whenever possible rather than the employee physically moving materials. 4.2.3 Mechanical assistance will be of proper size and height, have wheels sized for the terrain, and be designed to prevent pinching or undue stress on joints. 4.2.4 Mechanical equipment or assistance shall be inspected and appropriately maintained. Defective equipment shall be tagged, removed from service, and repaired or replaced. 4.2.5 Objects to be moved will be secured to prevent falling and properly balanced to prevent tipping. 4.2.6 Material handling tasks should be designed to minimize the weight, range of motion, and frequency of the activity. 4.2.7 Alter the task to eliminate the hazardous motion and/or change the position of the object in relation to the employee's body—such as adjusting the height of a pallet or shelf. 4.2.8 Work methods and stations should be designed to minimize the distance between the person and the object being handled. 4.2.9 Confirm well-lit and clear paths of travel. 4.2.10 High-strength push-pull requirements are undesirable, but pushing is better than pulling. Material handling equipment should be easy to move, with handles that can be easily grasped in an upright posture. 4.2.11 Workbench or workstation configurations can force people to bend over. Corrections should emphasize adjustments necessary for the employee to remain in a relaxed upright stance or fully supported seated posture. Bending the upper body and spine to reach into a bin or container is highly undesirable.The bins should be elevated, tilted, or equipped with collapsible sides to improve access. 4.2.12 Repetitive or sustained twisting, stretching, or leaning to one side are undesirable. Corrections could include repositioning bins and moving employees closer to parts and conveyors 4.3 Administrative Controls 4.3.1 Task hazard assessment(THA)must include manual material handling, its associated hazards and the appropriate actions to take to eliminate or reduce the identified risks. 4.3.2 Stage materials close to the applicable work area to minimize carrying distances. 4.3.3 When significant, sustained lifting work is required, it is desirable to rotate employees to spread the work load among several people and thereby avoid fatigue. 4.3.4 Rotation is not simply performing a different job, but is performing a job that utilizes a completely different muscle group from the ones that have been overexerted. 4.3.5 All employees exposed to manual handling hazards shall be trained by competent persons on the hazards associated with manual material handling, and the safe lifting and handling of loads applicable to their anticipated manual handling tasks. 4.3.6 Employees shall not manually handle materials in excess of their personal lifting limit, with no personal lifting limit exceeding 50 pounds(22.7kg). • Manual handling weight limits may decrease from 50 pounds(22.7kg)depending upon several variables. Refer to S3AM-014-ATT1 Recommended Weight Limit Calculations. • This restriction should also be applied to a team handling or a buddy lift(item lifted by the team should be no more than 50 pounds[22.7kg]). Should one lifter fail,the remaining worker would bear 100%of the load weight. Manual Lifting(S3AM-014-PR1) Revision 2 July 31,2019 PRINTED COPIES ARE UNCONTROLLED.
