Mud Safety — Part 2

Sometimes mud is unavoidable. Whether you’re parked at an unpaved lot at a jobsite or pulling off the pavement to inspect a roadway, bridge or other work, odds are that at some point you’ll have to navigate some mud and muck. Below are pointers for getting a vehicle out of the mud.

Rock It Out

If the vehicle has four-wheel drive, lock it in. Put the vehicle in reverse with wheels straight, and gradually accelerate. If this is not enough to get the vehicle to solid ground, shift into low gear, and slowly power forward as much as you can. If the tires spin, turn them from side to side in an effort to get the edge of the tread to grip the surface. Repeat this back-and-forth process as long as you continue to make progress.

Add Traction

Place dry, solid objects such as floor mats, rocks, limbs or boards beneath the edge of the tire in the direction you want to drive. Reduce the amount of air pressure in the tires. Offroaders.com recommends dropping the pressure to between 15 and 20 pounds per square inch. If the vehicle is resting on the undercarriage, use a jack to lift the tires off the ground — if the jack can sit on a solid surface. Never crawl under the vehicle while it is jacked up. Once you lift it even a few inches, you can slide a solid item beneath the tires to provide lift and traction.

Winch It Out

If you have to drive through mud on a regular basis, it is wise to outfit your vehicle with a winch. You can also use a come-along or a hi-lift jack to pull a vehicle free, provided there is a tree or other solid object close enough to wrap a recovery strap around. Check all of the hooks and eyes attached to your draw cable and use good judgment about the size of the tree or other anchor points you will need. If you are using a winch, place a blanket over the center point of the steel cables. In the event the cable snaps, the weight of the blanket should keep the cable from whipping into the air, possibly injuring you or damaging the vehicle. Loop the winch cable or recovery strap around the solid object, and use the power winch, come-along or jack to slowly pull the vehicle out of the mud. Never stand next to the winch cable or any of the fittings when the winch begins to draw tight.

Pull It Out

If another vehicle is available, the best and quickest way to get a vehicle out the mud is to pull it out. Attach a webbed recovery strap or chain to the tow hitches, frame-mounted tow hooks or the frames of both vehicles, as long as you can get to them without putting tension on less solid parts of the vehicles. Straps are best for pulling, but if you must use chains, inspect them to ensure that they are in good condition. Never attach a strap to a bumper, axles, suspension or the hitch ball as these parts are easily damaged. Put the stuck vehicle in gear. The mobile vehicle should very slowly pull most of the slack from the strap or chain and continue to accelerate gradually. The driver of the stuck vehicle should apply gradual pressure to the gas pedal as the vehicle begins to move. Bystanders should stay two to three car lengths away from the vehicles involved to ensure their safety in the event the strap or chain breaks or one of the vehicles begins to slide.

Mud Safety — Part 1

April is the month for rain showers — and mud. Mud is a major contributor to many safety issues that lead to severe work-site accidents and injuries. All mud is slippery; the higher the clay content of the soil, the slipperier the mud. It sticks to the bottom of boots and tires and transforms any surface it touches into a potential slip hazard. Every year, dozens of falls occur because workers slip off of ladder rungs, equipment and walk surfaces as they attempt to climb or walk while wearing muddy boots. Driving accidents occur when muddy boots slip off the brake or accelerator pedals, causing the driver to lose control.

Mud is impossible to eliminate; however, if you follow the guidelines below, your work environments will be cleaner and safer during the rainy season.

  • Lay down gravel or geo cloth to protect walkways and keep mud from forming.
  • Use boot brushes or other means to clean off your boots before walking on smooth surfaces where you might slip.
  • Maintain drainage on job sites and roads, so water doesn’t pool in low areas, forming mud puddles.
  • Always clean mud from your boots before you climb on anything.
  • Clean tool handles prior to storage.
  • Keep material staging areas well drained, and stack material using cribbage so that it is up off the ground.
  • Position portable toilets on higher, well-drained ground, so workers don’t have to walk through pools of mud to reach them.
  • Provide sufficient dunnage for cranes and other equipment, so they are working on stable surfaces.
