2. General Requirements For Manual Handling • Employees should seek help when: • A load is so bulky it cannot be properly grasped or lifted • An employee can’t see around or over it • A load cannot be safely handled. • Personal Protective equipment is an integral part of safe handling procedures. • Boots with sturdy soles • Gloves • Forearm Protection • Safety Glasses

3. Manual Handling - Back Injury Facts • There are approximately 700,000 back-related injuries in the United States each year. • Back injuries comprised 32% of all injuries reported, but consumed more than 40% of all workers' compensation dollars. • Because they are often slow to heal and are likely to reoccur, back injuries are a costly injury.

4. The NIOSH Lifting Equation • NIOSH – National Institute for Occupational Safety and Health • Created a formula for evaluating on-the-job lifting tasks • The equation establishes an “RWL” or Recommended Weight Limit for the individual employee/task • ( RWL = LC x HM x VM x DM x AM x FM x CM )

5. Components of the Equation • LC (Load Constant) – Usually 51 lbs • HM (Horizontal Multiplier) – The distance of the hands from the midpoint of the body (10 to 25 in) • VM (Vertical Multiplier) – vertical distance from hands to floor (0 to 70 in) • DM (Distance Multiplier) – vertical distance of lift from start to finish (10 to 70 in) • AM (Asymmetric Multiplier) – measured angle of twist of the lift from start to finish (0° to 135°) • FM (Frequency Multiplier) – lifts per minute • CM (Coupling Multiplier) – ease of grasping the load (rated as GOOD, FAIR, or POOR)

6. Using the Equation • Once the RWL is determined, the LI (Lifting Index) is used; • LI = Load Weight/RWL • If the Lifting Index is at or above 1.0, the lifting task should be redesigned • What factors can help create an easier lifting task?

7. Mechanics of Proper Lifting • The following slides will demonstrate the basics of proper lifting technique • Don’t forget these basics; • Warming up before attempting to lift is good practice, don’t be afraid to get your blood flowing with some simple stretches. • There is no shame in the buddy system, get help if you think you’ll need it! • If management has provided equipment for helping you lift something, use it. Never take a short cut or put yourself in an unsafe position with a load.

9. General Requirements For Mechanical Handling • When moving materials avoid overloading, consider the weight, size, and shape of the material • Equipment capacity ratings must be displayed on each piece of equipment and must not be exceeded. • Follow safe lifting procedures for the specific machinery in use • OSHA requires that all machine operators are trained.

10. Forklifts • NIOSH Fatality Statistics • Average age of a fatally injured worker was 38 • The largest proportion of fatalities occurred to workers in manufacturing followed by transportation, communication and public utilities. • Three most common causes of fatalities • forklift overturn (operator not restrained) • pedestrians struck by forklift • workers crushed by forklift

11. Forklifts • Operator training was made mandatory for all industries as of March 1, 1999. • Employer must train operators using federal guidelines for certification. • Equipment that was designed to move earth but will accept forks is not covered, nor are over the road haulage trucks.

12. Which machine falls under 1926.602(d) ?

13. Forklifts Training must incorporate the following subject matter: • Familiarization with the Machine • Understanding the basics of stability • Understanding the forces that cause tip-over • Vehicle Inspection • Vehicle Operation • Load Handling • Power Source • LPG Handling and Use • Battery Charging • Hands-On Training

14. Forklifts • Refresher Training must be provided when: • An operator has an incident or near-miss incident • An operator is asked to run a different type of truck • The operator has been evaluated as not operating in a safe manner • Training records must be kept on file after the date of completion for at least three years • Operators are not subject to fitness tests • OSHA does not require certification cards

15. Mobile Cranes

16. Mobile Cranes • Inspection • OSHA requires all mobile cranes to be inspected regularly. • A pre-operational (frequent) inspection must be made by a competent person before each use of the crane. • OSHA also requires a monthly inspection of critical items and a thorough inspection of the entire crane at least annually. • Stand-by cranes must also be inspected to a pre-operational level at least every six months.

17. Mobile Cranes • Inspection • In accordance with federal regulations and the manufacturer’s guidelines, the following items must be inspected at minimum;

18. Mobile Cranes • Crane Set-Up • The operator must be aware of potential contact with power lines and maintain an adequate separation distance based on the voltage of the line. • Some form of highly visible physical barrier must be erected around the swing radius of the crane. • Blocking under outriggers should exceed the surface area of the float by at least three times and have no separation between lumber.

19. Mobile Cranes • Crane Set-Up • Load charts must be either posted or bound and readily accessible in the cab. • Inspection records and operators manual should also be on the vehicle at all times. • Accurate leveling of the crane is essential for safe lifting. Also, particular care must be taken to insure the surface under crawler cranes and cranes operating “on rubber” are level before making the lift.

20. Mobile Cranes • Safe Operating Procedures • Enforce the “no rider” rule. There must be approved seating for all personnel. Operators must use seatbelts at all times. • Never use a crane to drag a load sideways. (Sideloading) • If the operator has to leave the controls he/she must: • Land the load and place all control levers in neutral • Secure the crane against accidental travel • Set all brakes and locking devices • Shut off the engine

21. Mobile Cranes • If crane operation is frequently interrupted, the operator may leave the crane with the engine running so long as the crane remains in view and unauthorized entry is prevented. • Use tag-lines to control larger loads and in conditions where the weather is inclement. • Operator must take direction from only one designated signaler.

22. Signaling • Operators must only respond to signals given by the designated signal person. • Unless radios are available, the standard hand signals prescribed by ANSI/ASME B30.5 are to be used. • The following slides show basic hand signals

23. Signaling

24. Signaling

25. Sling Safety • Synthetic Web Slings • Can handle loads of up to 30,000 lbs • Will adjust to the load contour and hold it with a tight, non-slip grip • Is not affected by mildew, rot, or bacteria, resistant to most chemicals, has excellent abrasion resistance • Has low cost and long service life • Can absorb heavy shocks without damage • Is unaffected by temps up to 180°F • Comes equipped with warning threads sewn into core to show wear and prompt replacement.

26. Sling Safety • Wire Rope • Composed of individual wires twisted to form strands • Strands are then twisted to form the rope • Ropes utilizing wire cores have good heat resistance capabilities • Factors such as bending stresses, loading conditions, jerking, abrasion, corrosion, sling design, and materials handled are all factors that contribute to the shortened service life of a wire rope sling.

27. Sling Safety • Chains • Commonly used because of their strength and ability to adapt to the shape of the load. • Are prone to damage through sudden shocks • Chain slings are ideal for high heat applications, can be exposed to temperatures of up to 1000°F

28. Sling Safety • Inspection • Check slings for; • Severe corrosion. • Localized wear(shiny worn spots or frayed, isolated spots) • Damage or displacement of end fittings, hooks, rings, links, or collars. • Distortion of eyelets, individual links, or strands. • Limited flexibility • OSHA requires that wire rope slings be removed from service if it contains 6 randomly distributed broken wires or 3 broken wires in one strand in one lay. **Note** Proper storage is critical to maximizing the life of a sling.

29. Rigging Hardware Hooks • Clevis and Eye types are most common • Should be inspected for spot wear and elongation • Hooks should never be painted, this can hide cracks and other causes of failure • Latches should be in working order if originally equipped

30. Rigging Hardware Shackles • Chain or Anchor type • Shackle pins should never be replaced with bolts • Pin side always goes to the rigging hook, shims may be necessary to maintain center position • Inspection includes • Pin seats • Straightness • Signs of spreading • Overall wear

40. Combustible Storage • Combustible scrap, debris, and waste materials (oily rags, etc.) should be stored and removed from the worksite as promptly as possible  • Proper storage practiced to minimize the risk of fire including spontaneous combustion • Keep combustible materials away from potential ignition sources • Never store flammable or combustible liquids in access or egress areas

41. General Storage Requirements • Storage areas must be kept free from materials that may cause tripping, fires, or explosions. • Storage areas should not block or intrude on facility pathways • When stacking and piling materials consider • Height • Weight • Accessibility • Condition of the container

42. General Requirements For Storage • Consider availability of materials, safe movement of material handling equipment, and personnel. • Employees required to work in stored material vessels shall be equipped with a personal fall arrest system. • When a difference in work levels exists, some means of smooth transition must be employed, i.e. grading, ramps, blocking.

43. General Requirements For Storage • Compressed gas cylinders must be secured and upright. Different gases must be separated by at least 20 ft. or by partition with specific dimension and fire retardant capabilities. • Observe height limitations for stacked materials. • Ex.
