- Would you place one or more reflectors right at the curve (75 feet from the vehicle)?
- Would any others be required? Recommended? Think about it; then explain briefly.
- How many feet per second does a vehicle travel at 30 mph if it travels 88 feet per second at 60 mph?
- At 30 mph, a vehicle travels 44 feet per second, so if the reflectors or flares were placed 75 feet away, a driver would have less than two seconds warning before hitting your truck. Now, think about questions #1 and #2 again. Now where do you think the warning devices should be placed for safety?
- What if traffic could negotiate the turn at 55 mph? Would that change your placement of the warning devices? If so, how?
- How would you place your warning devices to protect your rig? Sketch your placement in the space below. (Be sure to indicate number of feet between devices in all your sketches.)
- Do you have to set out warning devices? If so, how many?
Breakdown Situation No. 3: You are in a left turn lane at a signal. Your engine quits. Use the space below to show how you would protect your rig.
Breakdown Situation No. 4: You are just pulling into the curb in a business district for a delivery. When you return, your wiring catches fire. You put out the fire and call the shop. You are advised to stay with the truck until evening when a mechanic will arrive after the shift change.
- Do you need emergency reflectors in this situation? Why or why not?
- How would your treatment of the situation change if you were carrying hazardous materials?
- Sketch your rig, the roadway and placement of reflectors if you would use any.
If the incident caused an injury or death, the Coast Guard National Response Center must also be notified immediately by telephone. DO: Read the sample hazardous materials incident that follows. Then, fill in one copy of the Hazardous Materials Incident Report with the information which you have taken from the written explanation below.
HINTS: Freight Forwarder means a trucking company. You probably could figure that out for yourself, but sometimes it helps to be sure. Under "Remarks," on the back of the form, write in a brief description of what caused the accident or incident; describe the spill, leak or other dangerous incident; tell who you (as Bob Griggs) notified and what steps you took to solve the immediate problem. With a little thought, you can probably figure out how to complete the rest of the form yourself.
Hazardous Materials Incident - Bob Griggs, Driver: Bob Griggs is a driver for Explosive Transport. On October 14th, he was traveling west on Interstate 10, carrying gunpowder for Diamond Powder Company, Bluerock Road, 900 S.W., Tucson, Arizona, 80520. The consignee was Walter Mining and Development Company, 10500 Uric Street, Cascade, Washington, 87541. Bob was to park at a safe haven (a spot authorized by the police department) at the outskirts of Yuma, AZ.
About five miles east of Yuma, his trailer lurched to the right side in the rear. This caught him by surprise. He couldn't figure out what was wrong because he had just checked his tires an hour previously, at 10:30 p.m., and everything had looked okay. Bob guided the rig off the road as easily as possible. The trailer was hopping around in the back, but he made it and got clear of the roadway.
At first, Bob couldn't figure out what had happened. He was especially confused since he had a new three-axle tractor:
In most cases, the number placard is only used for fluids - fuels, oils, etc. Other hazardous materials will normally be labeled only by the commodity's trade name, generic name and appropriate hazardous materials placard.
You are required to display the ID number in one of two places. You may display it right on the placard or you may display it on an additional rectangular orange panel.
Each individual package of hazardous materials must also be marked using the appropriate label. The type and degree of labeling depends on the hazard classification of the content of the container.
