    Materials Handling, Rigging & CranesSUBPARTS1 H,N,O

    Trainer's Notes:

    This Training module is designed to help you recognize and control some of the more common hazards associated with materials handling when doing construction work.

    If you spot problems on your site, or unsure of what to do, notify your supervisor. Awareness of basic aspects of material movement is critical, whether its equipment inspection or operation, rigging a load, or lifting something by hand.

  • Materials Handling DangersUnsafe storage and materials movement

    can lead to:

    Back injuries (the number one cause of worker compensation claims).Struck-by or crushed by falling loads due to rigging failures.Electrocutions due to power line contact.Injury from falling materials.Injury from slipping, tripping and falling.

    Materials Handling, Rigging & CranesSUBPARTS3 H,N,O

    Trainer's Notes:

    Review the dangers.

    Emphasize the fact that materials handling occurs from the beginning of the job to the end and whether mechanical or manual, holds a potential for many injuries.

  • Moving Materials by Hand: Back Facts8 out of 10 Americans will have a back injury during their life.Approximately 1 out of 3 injuries at work are back injuries.Personal pain and inconvenience can not be measured.Back injuries cost employers an estimated 10 billion dollars each year!

    Materials Handling, Rigging & CranesH, N, OSUBPARTS4

    Trainer's Notes:

    Review the facts with the participants.

    Ask for a show of hands concerning back problems.

  • Preventing Back InjuriesYou can avoid back injuries by:

    Using mechanical aids.Using proper lifting techniques.Keeping in lifting shape.Working as a team when lifting.Knowing the truth about back belts.

    Materials Handling, Rigging & CranesH, N, OSUBPARTS5

    Trainer's Notes:

    Review the components with the participants.

  • Proper Lifting TechniqueBasic moves of a proper lift:

    Plan your lift.Use a wide-balanced stance.Get close to the load and keep it close to your body.Tighten your stomach muscles.Keep your back straight and use your legs.Turn with with your feet dont twist your back.Avoid lifting above shoulder height.

    Trainer's Notes:

    Review the components with the participants.

  • A Proper Lift

    Materials Handling, Rigging & CranesH, N, OSUBPARTS7

    Trainer's Notes:

    Review the steps a second time while you demonstrate with the box.

    Stress the importance of using the leg muscles, keeping the back straight, and keeping the load close to the body.

  • Keeping in Lifting ShapeKeeping your stomach and back muscles strong can help prevent back injuries.Even if you dont work out in a gym, you can prevent back injuries.Strength and flexibility exercises should be done at least every other day.

    Materials Handling, Rigging & Cranes8SUBPART H,N,O

    Trainer's Notes:

    Review the components with the participants.

    Stress how much of a difference strong stomach muscles can make when trying to prevent back injuries.

  • For Strength and Flexibility

    Materials Handling, Rigging & CranesH, N, OSUBPARTS9

    Trainer's Notes:

    Review the exercises with the participants.

    1. Knee to Chest Raise: Hold ten seconds repeat ten times.2.Wall Slide: Slide to a sitting position, hold for 3 minutes.3. Press-up: Hold for ten seconds, repeat ten times.4. Round and Arch: round your back up and touch your chin to your knees.5. Lower back Stretch: Hold for ten seconds.6. Back Stretch: Press your lower back to the floor.

  • Mechanical AidsUse hand trucks, dollies, carts, wheel barrows, and wagons whenever possible.Encourage management to include mechanical aids whenever possible.

    Materials Handling, Rigging & CranesSUBPARTS10 H,N,O

    Trainer's Notes:

    Ask the participants to name some of the more common mechanical aids they see around the work site.

  • Mechanical Aids

    Materials Handling, Rigging & CranesSUBPARTS11 H,N,O Slab carrying righere has eliminated bending over and has provided securenon-abrasive hand-holds.

    Trainer's Notes:

    Ask the participants to name some of the more common mechanical aids they see around the work site.

  • Team LiftingUse team lifting for:

    Loads too heavy for one person.Loads too bulky for one person.Long loads such as pipes and rolls of material.Talk to your team-mate!Coordinate your lift!

    Materials Handling, Rigging & CranesH, N, OSUBPARTS12

    Trainer's Notes:

    Ask them for examples of the type of materials they might team lift.

  • What About Back Belts?The National Institute for Occupational Safety and Health (NIOSH) says:

    Back belts may not reduce stress on the back.May increase blood pressure and heart rate.May make you think you can lift heavier loads with a belt on and you could get hurt trying to.

    If you want to wear a belt; dont wear it too tight and dont lift more than you usually would.

    Materials Handling, Rigging & CranesH, N, OSUBPARTS13

    Trainer's Notes:

    Review the NIOSH findings concerning back belts.

    Ask the participants if any of them have ever worn a back belt.

  • Material Storage Five basic rules for safe storage:

    Keep total weight within the safe loading limits of the buildings floors.Keep passageways clear.

    Control materials so they do not slide, fall, or collapse.

    Provide cribbing for heavy loads on unstable surfaces.

    Store materials away from traffic.

    Materials Handling, Rigging & CranesH,N, OSUBPARTS14

    Trainer's Notes:

    Ask the participants which one of the five they think causes the most problems on their work site.

  • What Does OSHA Require?Basic requirements:

    Dont put materials within 10 feet of roof edge.Dont store materials on scaffolds or runways.Keep materials at least 6 feet from floor openings and hoistways.Keep aisles clear.Keep work area free from tripping, fire, explosion, pest and vegetation hazards.

    Materials Handling, Rigging & CranesH,N,OSUBPARTS15

    Trainer's Notes:

    Ask the participants for stories concerning materials blowing or falling off of roof edges.

  • OSHA Also Requires Specific requirements:

    Stack bagged materials by stepping back the layers and cross-keying the bags at least every 10 bags high.

    Stack bricks no higher than 7 feet.

    Taper masonry blocks back one-half block per tier for stacks above 6 feet.

    Stack lumber on sills and on level solid ground - never exceed 16 feet high and always remove nails!

    Materials Handling, Rigging & CranesH,N,OSUBPARTS16

    Trainer's Notes:

    Review the specific requirements.

    Ask the participants if they can think of any others.

  • Setting Materials on the DeckWhat could happen to these stacked materials?

    Materials Handling, Rigging & CranesH,N,OSUBPARTS17

    Trainers Notes:

    Use this or similar photographs to emphasize the importance of minimizing both fall hazards and falling material hazards in these situations.

    Note also that the flat roof situation does not change the rule. Putting material outside the warning line may seem better as it is out of the way, it is not allowed and would be a citation.

  • Disposal of Waste MaterialOSHA requirements:

    Scrap lumber, waste and trash must be regularly removed from the work area.

    Burning must meet local regulations.

    Materials dropped more than 20 feet require a chute.

    Solvent waste, oily rags, and flammables must be kept in fire resistant containers until removed.

    If the waste is considered hazardous, your employer will have to follow federal, state, and local regulations.

    Materials Handling, Rigging & CranesH,N,OSUBPARTS18

    Trainer's Notes:

    Getting rid of the trash is always a problem and housekeeping directly or indirectly is said to contribute to one-third of injuries.

  • Debris Chutes Objectives in using a chute: material control, dust control and protection of workers and bystanders note the differences here.
