Powered IndustrialTruck - 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.
Performance-Oriented Requirements • The powered industrial truck operator training requirements are performance-oriented to permit employers to tailor a training program to the characteristics of their workplaces and the particular types of powered industrial trucks operated.
Operator Training • Safe operations • The employer shall ensure that each powered industrial truck operator is competent to operate a powered industrial truck safely, as demonstrated by successful completion of the training and evaluation specified in the OSHA standard. • Prior to permitting an employee to operate a powered industrial truck (except for training purposes), the employer shall ensure that each operator has successfully completed the required training (or previously received appropriate training).
Training Program Implementation • Trainees may operate a powered industrial truck only: • Under direct supervision of a person who has the knowledge, training, and experience to train operators and evaluate their competence; and, • Where such operation does not endanger the trainee or other employees.
Training Program Implementation (continued) • Training shall consist of a combination of: • Formal instruction (e.g., lecture, discussion, interactive computer learning, written material), • Practical training (demonstrations and exercises performed by the trainee), and • Evaluation of the operator’s performance in the workplace
Training Program Implementation (continued) • Training and evaluation shall be conducted by a person with the knowledge, training and experience to train powered industrial truck operators and evaluate their competence.
Training Program Content • Operators shall receive initial training in the following topics, except in topics which the employer can demonstrate are not applicable to safe operation in the employer’s workplace. • Truck-related topics • Workplace-related topics • The requirements of the standard

Refresher Training and Evaluation • Refresher training, including an evaluation of the effectiveness of that training, shall be conducted to ensure that the operator has the knowledge and skills needed to operate the powered industrial truck safely. • Refresher training required when: • Unsafe operation • Accident or near-miss • Evaluation indicates need • Different type of equipment introduced • Workplace condition changes
Refresher Training and Evaluation (continued) • An evaluation of each powered industrial truck operator’s performance must be conducted: • After initial training, • After refresher training, and • At least once every three years
Certification • The employer shall certify that each operator has been trained and evaluated as required by the standard. • Certification shall include: • Name of operator • Date of training • Date of evaluation • Identity of person(s) performing the training or evaluation
Appendix A - Stability of Powered Industrial Trucks • Definitions • General • Basic Principles • Stability Triangle • Longitudinal Stability • Lateral Stability • Dynamic Stability
Stability Triangle - Figure 1 Vehicle Center of Gravity (Unloaded) B A Center of Gravity of Vehicle and Maximum Load (Theoretical) C 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 result in a truck that is less stable laterally.

Effective Powered Industrial Truck Operator Training Program • Four major areas of concern must be addressed: • The general hazards that apply to the operation of all or most powered industrial trucks; • The hazards associated with the operation of particular types of trucks; • The hazards of workplaces generally; and, • The hazards of the particular workplace where the vehicle operates.
Types of Powered Industrial Trucks • There are many different types of powered industrial trucks covered by the OSHA standard. • Commonly used types include: • High lift trucks, counterbalanced trucks, cantilever trucks, rider trucks, forklift trucks, high lift trucks, high lift platform trucks, low lift trucks, motorized hand trucks, pallet trucks, straddle trucks, reach rider trucks, high lift order picker trucks, motorized hand/rider trucks, and counterbalanced front/side loader lift trucks. • A single type of truck can only be described by calling it by all of its characteristics, (e.g., a high lift, counterbalanced, sit down rider truck).
Unique Characteristics of Powered Industrial Trucks • Each type of powered industrial truck has its own unique characteristics and some inherent hazards. • To be effective, training must address the unique characteristics of the type of vehicle the employee is being trained to operate.
A PIT is a PIT NOT a CAR • Controls are different from those of cars. • Steer very differently than cars. • Are used for different purposes than cars. • Steer from the rear, and have drive wheels in the front. • When turning, the rear end swings in a circle. • Front drive wheels support most of the load. • Less steering control when turning, especially if loaded. • Difficult to stop quickly and dangerous to swerve.
Components of a Forklift Truck* *One of the most common types of powered industrial trucks
Classes of Commonly-Used Powered Industrial Trucks* • The Industrial Truck Association has placed powered industrial trucks into 7 classes. • Class I - Electric motor rider trucks • Class II - Electric motor narrow aisle trucks • Class III - Electric motor hand trucks or hand/rider trucks • Class IV - Internal combustion engine trucks (solid/cushion tires) • Class V - Internal combustion engine trucks (pneumatic tires) • Class VI - Electric and internal combustion engine tractors • Class VII - Rough terrain forklift trucks * Note that this classification refers to commonly-used vehicles and does not include all powered industrial trucks covered by the OSHA standard.
Class I - Electric Motor Rider Trucks • Counterbalanced rider type, stand up • Three wheel electric trucks, sit-down • Counterbalanced rider type, cushion tires, sit-down (high and low platform) • Counterbalanced rider, pneumatic tire, sit-down (high and low platform)
Class IV - Internal Combustion Engine Trucks - Cushion (Solid) Tires Fork, counterbalanced (cushion/solid tires)
Class IV - Internal Combustion Engine Trucks - Cushion (Solid) Tires
Class V - Internal Combustion Engine Trucks - Pneumatic Tires Fork, counterbalanced (pneumatic tires)
Class V - Internal Combustion Engine Trucks (Pneumatic Tires)
Pre-use Inspection • Must be done at least daily or at the beginning of each shift • Check the power-plant • Gas, Diesel or Propane Powered • Electric Powered • Check for damage and proper operation.
Performance Data • Gross vehicle weight without a load will always exceed the vehicle’s rated lifting capacity • Gross vehicle weight will normally be about 2 times the vehicle’s rated capacity • Weight distribution varies depending on load weight and position
Load Stability • NEVER EXCEED the rated load capacity of your PIT • Look for Impact or Capacity plate to find: >machine working capacity >gross vehicle weight >rated load center >capacity rating with attachment >tire data >attachment identification >maximum lift height
Reduce your load if: • The load is too tall, wide, oddly shaped or if you are using attachments. • A high lift is involved or if the route is rough. • The load can’t be centered on the pallet or carried close to your drive wheels. • You have to make tight turns or travel on a ramp or slope.
To Keep the Load Stable: • Space your forks as far apart as possible. • Make sure the load won’t shift while traveling. • Secure loose or slippery items. • Transfer loads on broken pallets to sound pallets before picking them up. • Wrap or strap loads made up of individual items.
Load Capacity • Attachments • Batteries • When in doubt consult your supervisor
Stability in Practice • Your PIT and load become less stable in any of the following situations: • whenever the load is raised • when you are turning • on slopes, either front to back or side to side • when tilting the load forward or backward, or side to side • on rough or uneven surfaces

STATIC FORCES are affected by: a) load characteristics b) lift height c) amount of tilt d) tire condition DYNAMIC FORCES are affected by: a) acceleration b) travel speeds c) braking d) surface condition Center of Gravity Will Shift
Counterbalance • load is carried at front of vehicle and is offset or counterbalanced by the weight of the vehicle located behind the drive tires which act as a pivot point • internal combustion-engine, steer axle, transmission, counterweight, and frame • electric powered battery, control panel, motors and pumps, steer axle, counterweight, and frame
Some Questions to Help Judge a Load: • What is the rated load capacity of my truck? • Is this load well within the capacity limits? • Will the shape of this load affect my stability? • Will the load affect my visibility? • Do I need to split up the load? • Do I need to drive in reverse? • What hazards are along the route? ?
Some Questions to Help Judge a Load: • What turns will I have to negotiate? • Are there ramps, slopes, rough ground or obstacles? • What about the destination? • Can I get close enough? • Can I pull straight in? • Is the area free of overhead hazards like power lines, pipes or ventilation equipment? ?
Gasoline Principles of Internal Combustion • Fuel Type • Engine Starting Conditions • Refueling • Changing an LP Tank
Principles of Electric Battery Power • Three Primary Voltage Types • Recharging a Battery • Trained Personnel ONLY • SOPs • PPE • Designated Areas ONLY
Maintenance of PITs • If defective, take out of service • Repair by authorized personnel only • Repair parts as safe or safer than original • Do not alter from manufacturer’s design • Repair in designated location
Safe Parking Procedures • How and Where to Park? • Attended Parking • Unattended Parking • Parking on an incline
Lifting a Load • Level the forks and slowly drive forward until the load rests against the mast. • Do not slam a load into the carriage. • Lift the load high enough to clear whatever is under it. • Assess the stability of the load. • Tilt the mast back slightly to a traveling position.
Lifting a Load • If there is another load in front of yours, lift without tilting. • Reassess load stability. • Look over both shoulders to make sure it is safe to move in reverse. • If there are no obstacles to the rear, back out slowly about one foot to insure the load will clear. • Back away to completely clear the load. • Lower load to travel and reassess load stability.
Carrying the Load • Keep your vehicle under control at all times • Keep forks close to floor • Maintain safe distance (3 vehicle lengths) • Examine surfaces - safety and strength • Safe speed - a brisk walking pace
Carrying the Load • Stay within the vehicle lanes. • Look over both shoulders before you back up. • Stop before raising or lowering loads. • Tilt the load slightly back with forks low. • Drive at a slow, steady pace. • Observe speed limits and controlled • Slow down for turns, sound your horn and stay near the inside corner.
