Safety Requirements NOTE: Show PPt #3

In a training environment, leaders must perform a risk assessment in accordance with ATP 5-

19, Risk Management. Leaders will complete the current Deliberate Risk Assessment

Worksheet in accordance with the TRADOC Safety Officer during the planning and completion of each task and sub-task by assessing mission, enemy, terrain and weather, troops and support available-time available and civil considerations, (METT-TC). Note: During MOPP training, leaders must ensure personnel are monitored for potential heat injury. Local policies and procedures must be followed during times of increased heat category in order to avoid heat related injury.

Environmental Considerations NOTE: Instructor should conduct a risk assessment to include environmental considerations

IAW the current environmental considerations publication, and ensure students are briefed on hazards and control measures.

Instructors must complete a risk assessment before conducting training, operations, or C-1 logistical activities. Abide with all applicable laws and regulations.

Based on its commitment to environmental protection, the Army will conduct its operations in ways that minimize environmental impacts.

• Comply with all environmental laws and regulations. This includes federal, state, local, and

Host Nation laws.

• Prevent pollution at the source by reducing, reusing, and recycling material that causes pollution.

• Conserve and preserve natural and cultural resources so that they will be available for present and future generations.

• Ensure drip pans and spill kits are on hand to prevent / mitigate any Petroleum, Oil, and

Lubricant (POL) spills.

• During refueling operations ensure fuel nozzle is properly in the fuel tank, operator has physical control of the fuel nozzle/handle and is trained on reacting to a fuel or POL spill.

Units and installations will prepare an environmental risk assessment using the before, during, and after checklist. The checklist should supplement local and state environmental regulations applicable to your area.

Instructional Lead-in The Military 621G Scraper is an earthmoving machine designed to operate using a push tractor for loading assistance. This machine is used to cut, haul, dump, and spread soil in worldwide earthmoving and construction projects by U.S. Army forces in engineer troop support.

The machine is able to load quickly, haul at high speed, and dump on the go. The machine is equipped with a single joystick control of implements, adjustable arm rests, seat, and steering column to reduce operator fatigue.

A cushion-hitch system improves ride quality by dampening load-induced ride harshness carried through the frame to the operator.

Security Classification: This course/lesson will present information that has a Security Classification of: U - Unclassified.

NOTE: Read all warnings and cautions in the TM before operating the machine.

Warning: Hearing protection is required when standing within 26 ft (8 m) of the machine while it is operating. Failure to wear hearing protection may result in hearing loss.

NOTE: Show PPt #38

1. Safety Requirements

NOTE: Show PPt #39

a. Hard hats and hearing protection will be worn when on or near equipment.

b. Perform a 360 degree walk around.

c. Do not carry tools or supplies when mounting or dismounting machine.

d. Mount and dismount the machine only at locations that have steps and grab handles.

e. Ensure steps and grab handles are clean prior to mounting machine.

f. Face machine during mounting and dismounting.

g. Do not use any controls as grab handles during mounting or dismounting.

h. Use three points of contact (two hands and one foot, or one hand and two feet) when climbing in, out of, or on the equipment.

i. Do not mount or dismount a moving machine.

j. Do not jump off a moving machine.

k. Remain aware of your surroundings.

l. Wear your seatbelts.

m. Never back up without a ground guide and remember they are in control “PAY

ATTENTION".

n. When acting as ground guide always maintain eye to eye contact with the operator.

o. At the first sign of lightning dismount the equipment and find shelter.

p. Failure to follow these warnings may result in injury or death to personnel.

2. Operational Safety

a. Only allow the operator on the machine. Keep riders off.

b. Riders on machine are subject to injury such as being struck by foreign objects and being thrown off the machine. Riders also obstruct the operator’s view resulting in the machine being operated in an unsafe manner.

c. Power lines

d. Over hangs

e. Trees

f. Look in direction of travel.

g. Never turn steering wheel with bowl fully raised.

h. Travel only on haul roads that have been authorized for your use and have been properly maintained. Avoid making deep ruts in road. Travel next to previous track to reduce rutting.

i. Loaded machines always have the right of way, unless otherwise directed by supervisor.

Note: Speed is governed by smoothness of haul road, by favorable or adverse grades, and by underfoot conditions. Keeping bowl low enhances stability at high speeds and on uneven roads.

- “Loping” is a rhythmic up-and-down motion of the machine. Slower speeds are necessary if uneven surfaces create loping.

j. Travel at a safe speed for the road conditions. Use higher speeds on smooth, level surfaces. Use lower speeds for rough, rolling surfaces or when there is traffic congestion at work site.

k. Use service brakes and downshift as needed and reduce machine speed and engine rpm. Reduce machine speed when turning.

l. If a ground guide is encountered at blind spots or crossings, obey guide’s signals.

m. Carry bowl low for best stability, but high enough so that bowl has adequate ground clearance. Under normal circumstances, proper travel height can be gauged by raising bowl until steering cylinders are level with the ground.

n. Select gear speed for downgrade that is same as gear speed needed for similar upgrade. Use transmission hold control to keep transmission from upshifting.

o. If machine starts to slip when traveling across a hillside, turn machine to downhill side. Turn machine to downhill side whenever machine is unstable.
