1. General Safety Guidelines

NOTE: Show VGT #5

NOTE: Stress the importance of individual responsibility in ensuring safety practices are

followed during daily activities, at work, and at the training site. Explain that

safety briefings will be conducted prior to training and after all breaks and that safe

practices will be enforced at all times. Instruct the students to report any unsafe

act immediately.

a. Running

Running is prohibited during all phases of the course due to safety reasons. If you have to getsomewhere fast, use a range walk.

b. Horseplay

(1) Horseplay during any training phase will not be tolerated at any time.

(2) Horseplay is grounds for removal from the training area until your chain of command canassure the training phase chief of your willingness to receive training.

c. Hearing protection

(1) Hearing protection is mandatory during training outside the classroom.

(2) When running, the equipment is very loud. If you are not wearing hearing protection, thesound can damage your hearing.

f. Wearing of jewelry

(1) Do not wear jewelry during the equipment training phases.

(2) If you are wearing a wedding band, wrap the ring with tape so it will not catch on theequipment.

(3) Remove your identification tags (dog tags) and place them in your pocket.

2. Review

Determine if students understand the material presented by:

1. Safety Hazards

NOTE: Show VGT #6

NOTE: Explain the types of safety hazards and ways to avoid injury.

a. Falling objects

When working around heavy equipment, there is a risk of injury from falling objects. Tools leftabove your head or opened engine panels can fall and hit you. Rock and other material may fallfrom the head wall, or spill over from the crushers. Stay alert at all times.

b. Flying or thrown objects

(1) When operating and working around heavy equipment, parts can break off and become flyingobjects that can cause personnel injury or death.

(2) DO NOT throw any object at any piece equipment or personnel.

(3) Use hand signals to get the operators attention; do not use a rock or dirt clod.

c. Weather conditions

(1) Heavy equipment can be operated in most weather conditions. There is a risk, however,during electrical storms. Large equipment in wide-open training areas will attract lighting.

(2) During electrical storms, shut the equipment down and get away from it as soon as possible.

(3) During cold and icy conditions, the equipment may become slippery. Use handrails on catwalks and ladders

d. Dehydration/heat injuries

(1) While in training during the summer, the humidity level can get high enough to cause yourbody to lose water at a rapid rate.

(2) If fluid is not replaced, you are prone to dehydration and heat injuries. You must drink a lot ofwater every hour to prevent dehydration.

e. Equipment mount and dismount

(1) When mounting a piece of equipment, always face the equipment and use all handrails andsteps.

(2) Use the three-point contact method to mount the equipment. Use both hands and one foot ata time to mount the equipment.

(3) DO NOT jump off the equipment for any reason. This is a safety violation that could lead toyour removal from training.

f. Fires

NOTE: Define the three types of fires that may occur in the heavy equipment environment,

the methods used to extinguish each type, and the safety measures to use when

extinguishing each type of fire. Point out the international symbols used on

extinguishers that tell the user on what class of fire it may be used.

NOTE: Show VGT #7

(1) Class A fire

(a) Ordinary combustibles such as wood, cloth, and paper

(b) Fire extinguishers for Class A fires

1) Pressurized water model extinguishers are appropriate for Class A fires, but mustnever be used on electrical or flammable-liquid fires.

2) Ammonium phosphate dry chemical extinguishers are appropriate for Class A fires,but should never be used on a grease fire.

3) Carbon dioxide extinguishers are rated for use on Class B and C fires, but can beused on a Class A fire.

NOTE: Show VGT #8

(2) Class B fire

(a) Flammable liquids such as gasoline, oil, and oil-based paint

(b) Fire extinguishers for Class B fires

1) Carbon dioxide extinguishers contain pressurized liquid carbon dioxide, which turns toa gas when expelled.

2) Ammonium phosphate dry chemical

3) Sodium bicarbonate dry chemical extinguisher is preferred over other dry-chemicalextinguishers for fighting grease fires.

4) Potassium bicarbonate, urea-base potassium bicarbonate, and potassium chloridedry chemical extinguishers are more effective and use less agent than sodiumbicarbonate on the same fire.

NOTE: Show VGT #9

(3) Class C fire

(a) Energized electrical equipment, including wiring, fuse boxes, circuit breakers, machinery,and appliances

(b) Fire extinguishers for Class C fires

1) Carbon dioxide

2) Ammonium phosphate dry chemical

3) Sodium bicarbonate dry chemical extinguishers

4) Potassium bicarbonate, urea-base potassium bicarbonate, and potassium chloridedry chemical

a. Equipment Knowledge

(2) Equipment selection

Using the proper equipment for the job not only saves money, time, and effort, but also saveswear and tear on the equipment. For example, you should never use a grader to dig a tankditch, or a bulldozer to perform final grading operations.

b. Walk-around inspection

(1) Before mounting and after dismounting a piece of equipment, you must do a 360 walk-around inspection.

(2) Look for leaks, missing parts, or for any problems that may have occurred since your lastinspection.

c. Job site safety hazards

(1) Any time you are on a construction site, you should always check the site for potential safetyhazards.

(2) Examples of job site safety hazards include:

(a) Working in close quarters with other equipment

(b) Hauling roads that cause dusty conditions

(c) Working on the ground around the equipment

d. Reporting unsafe actions

(1) It is everyones responsibility to act safely and to report any unsafe acts witnessed.

(2) Accidents normally occur after you have been around the equipment for some time and beginto feel confident while operating it.

(3) If you stay alert and obey all safety rules, you will help minimize the chance of accidents.

2. Review

Determine if students understand the material presented by:

(1) Soliciting student questions and explanations.
