Some is moved by machine and some by hand. When handling material, technique is everything. Industrial Safety Lecture Four 2 3/18/2016 Causes of Injuries 25% of all injuries are related to material handling. 80% are to the lower back. Incorrect lifting causes most injuries. Incorrect use of equipment. Industrial Safety Lecture Four 3 3/18/2016 Carelessness Be aware of your environment. Hey Charlie! Did you see that game last night? Industrial Safety Lecture Four 4 3/18/2016 Avoiding Workplace Injuries Stay in shape. Consider where you will walk. Don’t use your body if you don’t have to. Industrial Safety Lecture Four 5 3/18/2016 Rules for Lifting Get close to the load. Keep feet apart. Keep back straight. Bend your knees. Tuck your chin. Grip the load with your palms. Industrial Safety Lecture Four 6 3/18/2016 Hazards Associated with Materials Handling Check your environment for sufficient moving room Check for projecting objects, wear gloves. Are materials secure? Are chemicals to be moved? Industrial Safety Lecture Four 7 3/18/2016 Teamwork and Handling Various Shapes and Sizes If an object seems to heavy to lift, it probably is. When working with others, communication is critical. Your back should be kept straight when you carry objects. Special lifting tools should be sought out and used for large objects. Protect yourself when handling things.

It is not a substitute for any of the provisions of the Occupational Safety and Health Act of 1970, or for any standards issued by the U.S. Department of Labor’s Occupational Safety and Health Administration (OSHA). It is also not a substitute for a powered industrial truck operator training program. 22 Acknowledgment OSHA’s Office of Training and Education wishes to acknowledge the following for contributing some of the graphics used in this presentation: – – – – Caterpillar Lift Trucks Mason Contractors Association of America Industrial Truck Association State of Utah Labor Commission - Occupational Safety & Health Division – Steamship Trade Association of Baltimore – Taylor Machine Works, Inc. – UAW - Ford National Joint Committee on Health and Safety Appearance of products does not imply 23 endorsement by the U.S. Department of Powered Industrial Truck - Definition A mobile, power-propelled truck used to carry, push, pull, lift, stack or tier materials. [American Society of Mechanical Engineers (ASME) definition] Excluded are vehicles used for earth moving and over-the-road hauling. Commonly known as forklifts, pallet trucks, rider trucks, forktrucks, or lifttrucks. Can be powered through electric or combustion engines. 24 Scope of Standard The scope provisions of 1910.178(a), which are based on ANSI B56.1 - 1969, remain in effect and cover: – ... fork trucks, tractors, platform lift trucks, motorized hand trucks, and other specialized industrial trucks powered by electric motors or internal combustion engines. – It does not apply to compressed air or nonflammable compressed gas-operated industrial trucks, farm vehicles, nor vehicles intended primarily for earth moving or overthe-road hauling. This scope covers general industry, construction 25 and shipyards. Scope of Standard (continued) For marine terminal and longshoring industries, all powered industrial trucks are covered, no matter what specialized name they are given. This includes, but is not limited to, straddle carriers, hustlers, toploaders, container reach stackers, and other vehicles that carry, push, pull, lift, or tier loads. 26 Reasons for New Standard Powered industrial truck accidents cause approximately 100 fatalities and 36,340 serious injuries in general industry and construction annually. It is estimated that 20 - 25% of the accidents are, at least in part, caused by inadequate training. 27 Additional Reasons for New Standard Updated consensus standards have been published. OSHA has been petitioned to improve the requirements for industrial truck training. Advisory Committee on Construction Safety and Health has recommended improving the standard. Resolutions have been introduced in the Senate and House urging OSHA to revise its outdated standard. 28 Forklift Fatalities, 1992-1996 120 86 1992 95 89 1993 114 1994 1995 1996 Source: Bureau of Labor Statistics, Job Related Fatalities Involving Forklifts 29 Forklift Fatalities by Age Group 1992 -1996 12% 5% 21% Under 20 3% 20 - 24 25 - 34 10% 35 - 44 45 - 54 56 - 64 65 & over 22% 27% Source: Bureau of Labor Statistics 30 Industries Where Powered Industrial Truck Accidents Occurred Source: OSHA Fatality/Catastrophe Reports, complied by OSHA Office of Electrical/Electronic and Mechanical Engineering Safety Standards. 31 Nonfatal Occupational Injuries and Illnesses by Source, 1996 32 Source: Bureau of Labor Statistics, Job Related Fatalities by Selected Characteristics, 1996. Background The previous OSHA standards, while requiring operator training, did not define the type of training or authorization required. March 15, 1988 - Industrial Truck Association (ITA) petitioned OSHA for specific training requirements. 33 Background (continued) American National Standards Institute (ANSI), in cooperation with ASME, has revised its standard 4 times, including current lifttruck technology and specific training topics. 34 Background (continued) OSHA published a proposed ruling on March 14, 1995 for General Industry, Shipyard, Marine Terminals, and Longshoring regulations, adding specific training requirements. On January 30, 1996, OSHA proposed a revision of the construction standards, mandating the development of an operator training program based on the prior knowledge and skills of the trainee and requiring a periodic evaluation. 35 Final Rule OSHA published the final rule for Powered Industrial Truck Operator Training on December 1, 1998. The effective date is March 1, 1999. Startup dates are included in paragraph (l)(7). It applies to all industries except agricultural operations. OSHA estimates that the new rule will prevent 11 deaths and 9,422 injuries per year. 36 Fatalities/Injuries Potentially Averted Annually by New Standard 37 Source: U.S. Department of Labor, OSHA, Office of Regulatory Analysis, 1997 Performance-Oriented Requirements The powered industrial truck operator training requirements are performanceoriented to permit employers to tailor a training program to the characteristics of their workplaces and the particular types of powered industrial trucks operated. 38 Revised Operator Training Requirements General Industry: 1910.178 is amended by revising paragraph (l) and adding Appendix A.

This appendix does not add to, alter, or reduce the requirements of this section. 53 Appendix A - Stability of Powered Industrial Trucks Definitions General Basic Principles Stability Triangle Longitudinal Stability Lateral Stability Dynamic Stability 54 Stability Triangle - Figure 1 B Vehicle Center of Gravity (Unloaded) A C Center of Gravity of Vehicle and Maximum Load (Theoretical) Notes: 1. When the vehicle is loaded, the combined center of gravity (CG) shifts toward line B-C. Theoretically the maximum load will result in the CG at the line B-C. In actual practice, the combined CG should never be at line B-C. 2. The addition of additional counterweight will cause the truck CG to shift toward point A and 55 result in a truck that is less stable laterally.
