Title: PowerPoint Presentation MATERIALS HANDLING


1
The Back and Material Handling Issues
2
The Spinal Column
3
The Basic Structure
4
Epidemiology of Back Injuries
  • Short Term or acute effects
  • Sharp Surfaces
  • Dropped Material
  • Struck-by Moving Materials
  • Mechanical Stress
  • Slips and Falls
  • Simpler Cause and effect relationship

5
Epidemiology
  • Chronic or Long Term Effects
  • Back Ache or Pain
  • Disc Degeneration
  • Cause and effect not as simple, more difficult
    to analyze

6
Return to Work
  • Out more than 6 months only 50 chance of
    returning
  • One year only 25
  • Management and Practitioner Training
  • One study showed that claims dropped from 200K
    to 20K per year by providing modified work and
    conservative treat

7
Material Handling
  • Lifting/Lowering
  • Pushing/Pulling
  • Carrying
  • Weights and Forces
  • Frequency of Activities
  • Load Center of Gravity

8
Material Handling
9
Job Risk Factors
  • Weight of the Object
  • Location (position of load w.r.t. worker)
  • Frequency of Lifts
  • Stability of the Load
  • Hand Coupling
  • Workplace Geometry Twisting/Stooping
  • Environmental Factors

10
Personal Risk Factors
  • Gender
  • Age
  • Anthropometry
  • Lift technique
  • Attitude
  • Strength
  • Training

11
Examples of Manual Handling Controls
  • Avoid extreme range of motion when lifting
  • Redesign work station/work area to allow freedom
    of movement
  • Provide handles on material handling equipment
  • Provide lift-assist devices and tables
  • Unit Load Concept

12
Job Design
  • Can reduce one-third of compensable LBP
  • Minimize reach and lift distances
  • Keep off floor
  • Work station design
  • Frequency
  • Relax time standard
  • Rotation
  • Work-Rest allowances

13
Job Design
  • Minimize Weight
  • Mechanical aids
  • Carton capacity
  • Balance contents
  • Convert
  • Carry to push/pull
  • Push over pull
  • Use large wheels

14
Training
  • Focus on awareness and avoidance
  • Get object as close to body as possible
  • Planning
  • Use of handling aids
  • Back Schools
  • Strength and fitness important

15
NIOSH Lifting Equation1991 Version
16
NIOSH Lifting Equation
  • Objective Reduce occurrence of lifting-related
    LBP
  • 1981 and 1991 equations
  • 1981 limited to sagittal plane
  • 1991 includes asymmetry and coupling

17
Disqualifiers for Use
  • One handed lifts
  • More than 8 hours
  • Seated or kneeling
  • Restricted work space
  • Unstable Objects
  • Carrying, pushing or pulling while lifting
  • Wheelbarrows or shovels
  • High speed motion
  • Unreasonable foot/floor coupling
  • Unfavorable environment

18
Definition of Terms
  • RWL Recommended weight limit
  • LC Load constant
  • HM Horizontal multiplier
  • VM Vertical multiplier
  • DM Distance multiplier
  • AM Asymmetric multiplier
  • FM Frequency multiplier
  • CM Coupling multiplier

19
1991 Equation
RWL LC x HM x VM x DM x AM x FM x CM
20
1991 Guide
  • Compare RWL to Actual Load (L)
  • If Greater than or equal to 1 problem

21
Lifting Index
L RWL
22
1991 Multipliers
  • LC 51 Pounds
  • HM 10/H
  • VM 1-.0075 x / V-30/
  • DM .82 (1.8/D)
  • AM 1 (.0032 x A)
  • FM go to Table
  • CM go to Table

WISHA Workshop
31
WISHA
  • If the job is a hazard
  • Reduce weight of load
  • Increase weight of load so that it requires
    mechanical assist
  • Reduce the capacity of the container
  • Etc.
