It seems as though we have had some close calls lately in re-guard to jack placement, especially on steering axles. Most of the issues are due to rear air suspension settling. This is a big issue to me as it can endanger everyone's safety in the shop. This is a problem no matter the jack type or supports being used. For the safety of yourself and your coworkers-
Never get under a vehicle that is not properly supported by adequate support stands of the rated capacity. (NOT A JACK) No matter how quick the repair never assume the jack will stay up.
Always use wheel chocks on the drive wheels when in the service bay. (NOT A BLOCK OF WOOD) One set is good, two is even better. For all you know the truck you just pulled in might only have 2 spring brakes, one of which the spring is in five pieces, the other shoes are soaked with oil.
Before lifting with service jacks, "ALWAYS" dump the air suspension before lifting. This eliminates a lot of issues with tipping and slipping jacks and stands.
Finally, always leave a manual trans in neutral and check for neutral with the clutch fully depressed before turning that key. A lot of them have crank protection but most do not.
I realize most of this is elementary stuff. Over time I think we need a refresher of the basics, as that's why they call them accidents. Hopefully this saves just one from happening. If you would like to add to the list, have at.

Too often drivers guess how much power their accessories require so they use an over rated or under rated inverter only to encounter issues. These can range from an inadequately rated inverter that cannot handle the load or one that consumes more current than necessary.
Purkeys Fleet Electric recommends using a Kill-a-Watt Tester. It safely and accurately measures the current draw of ac-powered devices on the tractor. Once you know the wattage requirement of the device(s) and provide our technicians with the information, we can then design the custom configuration and properly select the correct dc-ac power inverter for the application.
Simply plug ac powered devices into to the Kill A Watt®, which is also plugged into an ac outlet. It will help you assess power consumption by displaying the wattage, voltage or current of your devices.
With this information, you will be able to make better decisions on what ac powered accessories to use in your truck and decrease the amount of service calls due to inadequate power conditions.
For more information about acquiring a Kill-a-Watt Meter for your fleet, please contact one of our technical experts today.

Safety Measurement System Changes
The Federal Motor Carrier Safety Administration’s (FMCSA) Safety Measurement System (SMS) quantifies the on-road safety performance and compliance history of motor carriers, to prioritize enforcement resources, determine the safety and compliance problems that a motor carrier may exhibit, and track each motor carrier’s safety. FMCSA designed the SMS expecting that changes would be made as new data, and additional analysis became available. This release is the first in a series of expected improvements to the SMS that will take place periodically.
FMCSA provided a preview period and opportunity to comment for enforcement personnel and motor carriers prior to the implementation of these SMS changes. In March 2012, the Agency announced in the Federal Register a proposed set of SMS modifications. The Agency also developed and released an SMS Preview, allowing a motor carrier to see the impact of the proposed modifications on the carrier’s SMS results in advance of the changes. The Agency collected and analyzed feedback from stakeholders through July 2012, and subsequently announced a package of SMS enhancements in December 2012.
This foundational document updates the June 2012 version of the foundational document and reflects SMS Methodology version 3.0. This updated version includes the final set of enhancements, including the original seven that were previewed as well as the four additional SMS changes that were recommended during the preview period.
The first package of the SMS enhancements includes:
1. Strengthening the Vehicle Maintenance Behavior Analysis and Safety Improvement Category (BASIC) by incorporating cargo/load securement violations from the Cargo-Related BASIC.
2. Changing the Cargo-Related BASIC to the Hazardous Materials (HM) Compliance BASIC to better identify HM-related safety and compliance problems.
3. Better aligning the SMS with Intermodal Equipment Provider (IEP) regulations.
4. Aligning violations that are included in the SMS with Commercial Vehicle Safety Alliance (CVSA) inspection levels by eliminating vehicle violations derived from driver-only inspections and driver violations from vehicle-only inspections.
5. More accurately identifying carriers that transport significant quantities of HM.
6. More accurately identifying carriers involved in transporting passengers.
7. Modifying the SMS display to: 1. Change current terminology, “inconclusive” and “insufficient data,” to fact-based descriptions. 2. Separate crashes with injuries from crashes with fatalities.
8. Removing 1 to 5 mph speeding violations.
9. Lowering the severity weight for speeding violations that do not designate the mph range above the speed limit.
10. Aligning the severity weight of paper and electronic logbook violations. With these changes, all violations related to not having a logbook, electronic or paper, now have a severity weight of 5.
Motor carriers can log in to CSA's SMS Website with your DOT Number to see how the changes implemented may affect you.

Appendix G is a list of defects that would fail the periodic (DOT Annual) inspection. It is the bare minimum that an inspector must check for during the inspection.
Out of Service Criteria is a set of guidelines for enforcement that is published yearly by CVSA (Commercial Vehicle Safety Alliance) and helps an officer determine which defects or conditions are such a hazard that the vehicle (or driver) should not be allowed to continue driving (place out of service, red tag)
As far as how they relate to each other, there are some Appendix G defects that are also in the OOS (out of service) criteria but for the most part OOS is more lenient than Appendix G.
For example; Appendix G says a vehicle doesn't pass a DOT Annual if one of the wipers doesn't work. However, in order to be placed out of service the vehicle would have no working wipers and it would also have to be raining or snowing at the time they were stopped.
Now, above both Appendix G and OOS criteria is where CSA vehicle maintenance violations come from. That is FMCSR Part 393 which can result in many violations not included in either Appendix G or OOS criteria.
