1. If a vehicle breaks down, operators must get the vehicle off and away from the travelled portion of the road if possible (this particularly applies to emergency vehicle routes on the project site). If they can't, then they must: Activate vehicle emergency flashers If visibility is poor because of fog, rain, hill, curve, dusk, etc., set out flares or flashers supplied with the vehicle Set flares or flashers 32 m (100 ft) behind and 32 m (100 ft) in front of the vehicle. (Do not set out flares if you are well off the road.)
2. Immediately report all Company vehicles breakdowns to head office.
3. Report accidents involving Company vehicles as described in Section 8 - Incidents. Give all the details possible, such as width of roads, length of skids, presence of traffic signs, vision obstructions, names and addresses of persons involved and witnesses. In case of an accident the operator must: Pull off the road, if possible, to avoid obstructing traffic Place warning reflectors on the road as necessary Render first aid to any person who may be injured Report the accident to his supervisor as soon as possible Refrain from entering into any argument or dispute with the driver of the other vehicle, pedestrians or bystanders Make no admission of liability or offer any settlement of claim Record license plate numbers and driver's license numbers of any other involved persons (including witnesses) Make arrangements with your supervisor to report the accident to the necessary authorities
Boosting a Battery
Always wear safety goggles to protect yourself from acid and fragments in case of an explosion. It’s a good idea to store safety goggles with your jumper cables. Check to see if the battery is really dead, or if the terminals and clamps might just be corroded. Restore correct fluid levels to the battery. If you are dealing with the more recent sealed type batteries, it is not always possible to restore these fluid levels. If this is the case, the battery should be replaced. Make sure the battery is not frozen. Trying to jump a frozen battery could result in an explosion. The electrical systems of both vehicles must be the same voltage and both must have a negative ground. Mismatched batteries are less likely than they were 20 years ago but six-volt batteries are still in use today. Using a 12 volt battery to boost a six volt battery could cause the six volt battery to explode. Part the vehicles close together, but not touching. Put both vehicles in “park” or in “neutral”, with parking brakes set. Turn off the engine, and any electrical accessories including interior lights on both vehicles. Remove the battery vent caps to allow any previously built up gas to escape. Then cover the holes with a damp rag or replace the caps. Do not lean over the battery at any time. Connect the red clamps to the positive “+” posts of each battery. Reverse connection causes a battery explosion hazard. Connect one black clamp to the negative “-“ terminal of the good battery. Connect the other black clamp to a good ground; a clean, unpainted spot on the engine, frame or body of the disabled vehicle, placing it as far away as possible from the battery. This will prevent sparks from occurring in the vicinity of any explosive gases. When connecting the clamps, do not allow them to touch any other metal. This would not only cause a spark which could trigger an explosion, but it could destroy parts of the vehicle’s electrical and computer system. Start the vehicle with the good battery. Start the disabled vehicle. Remove the cables in reverse order. Detach the “-“cable first from the disabled car’s frame. Then take the “-“of the good car’s negative terminal. Remove the disabled cars “+” cable. Then remove the live car’s “-“connection.
Other Tips Avoid any sparks or flames. NO SMOKING.
