Electrical linemen face a variety of potential hazards while on the job, not the least of which are dangers posed by traffic. Work zones must be clearly marked by signs or cones and the traffic routed away from the workers’ safe area as appropriate, but as long as linemen are working in a traffic zone, dangers remain. To improve traffic safety, careful attention must be paid to the job site, as well as to practicing safe operations when using equipment like bucket trucks.

Utility Fleet Sales and RentalTraffic Hazards

Many of the traffic hazards faced by electrical linemen are posed by drivers on the roadway on which the work zone is situated. On most major thoroughfares, the number of vehicles on the road at any given time has increased, and this factor must be considered. Sometimes workers do not set out sufficient warning signs and cones to alert drivers and safely control the flow of traffic. Other times, workers set up proper traffic control implements, but drivers still do not heed them, whether because they are distracted by items like cell phones or their vision is obstructed by frost on windows in cold weather or glare from the sun on a clear day.

Equipment Hazards

Bucket trucks are excellent tools when used by qualified operators and linemen to do their jobs, but special safety issues must be considered when they are used in traffic. One common situation is when the boom on a bucket truck extends over the road at an angle so the worker in the bucket can carry out his duties on power poles and lines. In this situation, there must be someone outside the bucket to control the flow of traffic.

Traffic Safety Planning

Proper traffic safety planning can make all the difference between a job that is safely completed and a job during which disaster occurs. Electrical linemen must come up with a work plan. First, crews must detail how long they expect to spend on the job, what the traffic flow is like at the area, and what the size and nature of the safe zone should be. Working at night poses additional hazards, and the possible presence of pedestrians should also be taken into consideration. Weather should also be part of traffic safety preparation, as well as rescue contingency plans.

In planning for traffic safety on a job site, it is vital that managers of electrical linemen crews work to identify the possible dangers and come up with plans to minimize and, where possible, eliminate those dangers. Local laws and safety regulations must be followed at all times. The safety of utility crews on roadways depends on careful job planning and adherence to proper safety protocol, as well as using considering the equipment that will help keep than safe such as insulated bucket trucks.

Planning is an important part of helping to ensure safety while on the job with a bucket truck. On reaching a job site, operators need to take stock of the area and the situation, since no two jobs are ever exactly alike. Once a plan is in place, workers need to do their best to follow it while also remaining mindful of how things could change. Planning combined with alertness will help workers prevent emergency situations, and also help them to respond better to emergencies, should they occur.

 

Situations Always Differ

Planning and taking stock of a situation before the start of a job is important, since conditions vary from job to job. Factors like traffic flow and weather will be different on any given day. The equipment with which workers perform their jobs can vary, as well. Before starting a job, it’s important to work to become aware of potential hazards and work to minimize those hazards so they won’t cause problems.

Getting Set Up

To get set up to work, it’s a good idea to position the bucket truck on the job site to where it will not have to be moved again once work begins. That’s the ideal, though, and it might not work in reality. A truck should be moved if it would require a worker to extend himself too much to get the job done. If a worker overextends himself, he is at much greater risk for injury. When the truck is positioned, cones and signs need to be set out as needed to alert motorists to the job site and give workers sufficient space.

Contingency Planning

Contingency planning is vital in case an emergency situation arises. Employees are required, per OSHA regulations, to hold a briefing prior to starting a job. As part of the briefing, workers need to discuss the particular conditions at work for that job, including equipment workers will use, procedures they will follow, relevant safety measures, possible hazards, and steps they will take if an emergency occurs.

Emergency Equipment

Setting out emergency equipment is an important part of planning for a job. Workers also need to test the communications radio, to make sure it is functioning and can be used in the event of an emergency. A pair of rubber gloves should be laid out, too, in case one of the workers needs to make contact with the truck while it’s in close proximity to energized power lines and equipment during an emergency, such as operating the boom or using the radio.

Bucket Safety

While a worker maneuvers the bucket into position from inside, another worker must be stationed on the ground to observe. A person standing on the ground will see the work environment from a different perspective and angle than the person in the bucket and can potentially warn the bucket operator about hazards that aren’t as easy to spot from inside the bucket.

Proper planning is critical to job safety, but it’s also important to stay on top of changing conditions while on the job. It’s this combination of planning and awareness that will work together to make the job at hand as safe as possible for everyone involved.

Most cases of hydraulic system failure in bucket trucks can be chalked up to three specific and common causes that result in excess heat, which contributes to damage and deterioration of components. These situations can all be minimized with regular maintenance and proper troubleshooting by qualified technicians. Always follow a maintenance schedule for your bucket truck and equipment that’s recommended by the manufacturer.

Contamination

The most common cause of hydraulic system failure is contamination, or when contaminants get into the system. Larger contaminants, or particles such as sand or shavings, can wear sizable grooves into the surfaces of components in a process called phonographing. The grooves caused by phonographing cause excessive heat and compromise the ability of the gear pump to do its work. Smaller-sized contaminants will cause significant wear and tear to the gear pump, making it much less efficient. They can also cause a condition known as jetting, where a profusion of small particles can erode a path of wear across the plate surface of the pump and cause pressure imbalance.

Over-pressurization

Over-pressurization occurs when a pump is operated beyond the capacity for which it is recommended. A pump running at a pressure that is too high will sustain damage to its various components, and overly high pressure will also result in failure of the hydraulic hoses and the cylinder packing. Problems caused by over-pressurization can happen whether the system is operated at a pressure that’s consistently too high or if the system is operated at high pressures that spike. A relief valve will help with spikes to an extent, but there will be damage if the spikes come in too great a frequency for the valve to cope with.

Cavitation

Cavitation occurs when an excessively high vacuum forms at the pump inlet, causing bubbles of gas to form in the hydraulic fluid. The bubbles form in the vacuum and then implode with a great deal of heat and energy at the pump’s pressure point. These implosions create excessive heat in the system and also damage components. Experienced troubleshooters can hear when cavitation has become an issue because of distinctive sounds that the bubbles’ implosion causes the pump to make.

The common denominator to all these causes of hydraulic system failure is the fact that they all result in excessive heat and damage to the components, which can compromise the functioning as well as the efficiency of a bucket truck’s important systems. It is vital for the people who service utility vehicles to keep the hydraulic systems free of contaminants as well as to always operate the equipment within recommended parameters.

Ever since the 19th century, trucks have been considered as one of the most important workhorses of modern man. They fill a variety of roles, ranging from heavy-duty construction to long-distance transportation. In many cases, many of the needed equipment for the job are loaded or built onto the trucks. The addition of a hydraulic arm or crane system allowed even more uses for trucks, particularly in reaching higher places that would otherwise have been difficult to access.
