 Safety Matters is intended to promote discussions of safety issues among underground construction professionals. TOPIC #1: DRILLING ATTACHMENTS—FOR DRILLING UNDER OBSTRUCTIONS SUCH AS SIDEWALKS AND DRIVEWAYS Potential Hazards• Caught in
• Struck by
• Drawn into | • Laceration
• Falls onto
• Buried utilities |
Precautions• Do not tape or tie down switch or lever. • Operate only from the operator's station. • Use a helper to add rods and hold rod guide. • Improper control function can cause serious injury. If the drill attachment rotation does not stop when control is released, stop operation and have machine repaired. Do not use machine if releasing control doesn't stop turning shaft. • Do not drill within 10 ft (3 m) of unexposed electric cables or gas pipes. • Keep everyone at least 10 ft (3 m) away from turning drill string unless using rod guide. • Keep everyone away from material being installed. If swivel malfunctions, material being installed can rotate. • Use a factory provided drill guide to align drill rod when starting a bore. • Stand to the left of the drill string. If the drill guide were to somehow get caught, it would turn in the direction of drill string rotation. • Keep the guide at least 3' behind the bit. • Do not use guide during backreaming or pull back. • Do not use guide for more than 3' to 6'. If the guide contacts the drill rod joint, it can cause injury. • Never use any part of your body to hold a drill string while turning. • Do not assemble more than 30' of rod at a time. The drill string will bow as it experiences a load. Information/Facts• When drill strings are put under a load, they can jump or walk unexpectedly. • Any part of clothing, hair or jewelry can become caught on a turning shaft. • Most drilling attachments can turn up to 140 revolutions per minute. • Turning shafts can kill you, remove a finger, arm or leg, break bones, cause castration, wrap up clothing tight enough to cut off circulation, tear ligaments, etc. TALES FROM THE TRENCH• A helper was standing on the rod as the operator started a bore. Burrs on the rods caused by breaking them apart and connecting them caught his pant cuff. The rods crawled up his leg. He had severe bruises causing concern of blood clots forming. Injured was off work for 2 weeks. • A helpers coat was caught in the drill string as he leaned over. He was slammed into the concrete several times before the rotation was stopped. His leg was broken in several places along with many other injuries to his body. • A worker was wearing coveralls with a frayed hole in the pant leg. The turning rods somehow caught the frayed hole and pulled him to the ground. Burrs were not found on the rods. He had severe bruising to his leg and groin. • A crew was drilling, hit an obstruction and had to back out to reroute the bore. They had approximately 90' of exposed drill rod. A crew member had his foot on the rod as it was turning. The drill string bowed and caught his pant leg causing torn ligaments in his leg. • A switch had been replaced and the yoke guard had been removed. An operator became tangled in the drill string and suffered severe injuries to his groin area. |

Stay Cool And Stay Alive
If you work outdoors, summer is one of your busiest times of the year because it’s typically the driest season and offers the most hours of daylight. But the sun providing all that productive daylight can be the biggest jobsite hazard you face all year. Excessive heat can bring down anyone who doesn’t take the necessary precautions.Keeping Your Fleet's Hydraulic Systems Running ProperlyIf your machine's hydraulic system isn't working, neither are you. Here are some common causes of hydraulic system breakdown and steps you can take to avoid them. Planning Ahead For WinterWinterizing your equipment is a small investment of your time that is guaranteed to pay big dividends. Your operator’s manual provides details on proper care during winter, but here are five essential steps you should take.
stopimg title="keepCool_img1" style="padding-right: 20px;" align="left" style="BORDER-BOTTOM: 0px solid; BORDER-LEFT: 0px solid; WIDTH: 260px; PADDING-RIGHT: 10px; HEIGHT: 195px; BORDER-TOP: 0px solid; align: left" alt="keepCool_img1" src="/uploadedImages/Left_Nav/Press_Room/Job_Related_List/1_KeepCool_260x195(1).jpg" border="0" />Catastrophic tornadoes and floods have grabbed recent headlines, but each year one weather phenomenon kills more people than tornadoes, floods, hurricanes, and lightning combined: heat.
According to the National Oceanic and Atmospheric Administration (NOAA), an average of more than 1,500 people in the U.S. die each year from excessive heat—yet it is the most preventable of weather-related deaths.
If you work in construction, summer is one of your busiest times of the year because it’s typically the driest season and offers the most hours of daylight. But the sun providing all that productive daylight can be the biggest jobsite hazard you face all year. No matter how tough you are or how used to the heat you think you are, excessive heat can bring down anyone who doesn’t take the necessary precautions.
The following information applies to anyone who is employed in an outdoor profession—construction workers in particular—but also applies to those who work in hot factories and anyone who spends time outdoors exercising, gardening, or laboring in any capacity during the summer months. (This is general information. More specific information can be found in the sources cited below.)
Know Your Chemistry
Our bodies dissipate heat by varying the rate and depth of blood circulation, and by expelling water through the skin and sweat glands. When we reach the danger zone, when our blood is heated above 98.6 degrees, we begin to pant—we’re literally “working like a dog.”
Sweating alone does little to cool the body, unless the sweat is removed by evaporation. But high relative humidity inhibits evaporation. When you’re checking the forecast for tomorrow, pay close attention to the heat index: the combination of relative humidity and air temperature. For example, if the air temperature is 96° F and the relative humidity is 65 percent, the heat index is 121° F. This is the heat your body really feels.
Heat disorders involve a reduction or collapse of our bodies’ ability to shed heat by circulatory changes and sweating, or a chemical (salt) imbalance caused by too much sweating. When heat gain exceeds the level the body can remove, or when the body cannot compensate for fluids and salt lost through perspiration, the temperature of the body's inner core begins to rise, bringing on various degrees of heat-related illnesses.
stopimg title="keepCool_img2" style="padding-left: 20px;" align="right" style="BORDER-BOTTOM: 0px solid; BORDER-LEFT: 0px solid; WIDTH: 260px; PADDING-RIGHT: 10px; HEIGHT: 195px; BORDER-TOP: 0px solid; align: right" alt="keepCool_img2" src="/uploadedImages/Left_Nav/Press_Room/Job_Related_List/2_KeepCool_260x195.jpg" border="0" />Ranking Heat Disorders
The severity of heat disorders is relative to a person’s age, weight, fitness, medical condition, and degree of acclimatization to the heat. For example, heat cramps in a 17-year-old may translate as heat exhaustion in someone who is 40, and heat stroke in a person over 60. Common heat disorders include:
- Sunburn. Along with being painful and irritating, sunburn can significantly retard the skin’s ability to shed excess heat. The best solution for sunburn is prevention, by applying sunscreen throughout the day.
- Heat cramps. Symptoms are painful spasms, usually in the muscles of the legs and abdomen, often preceded by profuse sweating.
- Heat rash. Also known as prickly heat, heat rash can occur in hot, humid environments where sweat is not easily removed from the surface of the skin by evaporation. Serious heat rash can be so uncomfortable that it inhibits sleep and impedes a worker’s performance.
- Heat exhaustion. Symptoms include heavy sweating, weakness, headache, fainting, vomiting, and skin that is cold, pale and clammy. It is possible to have a normal temperature with heat exhaustion.
- Heat stroke or sunstroke. This is the most serious health problem for workers in hot environments. Heat stroke occurs when sweating stops and the body can no longer rid itself of excess heat. Symptoms include an excessively high body temperature (106° F or higher); mental confusion or delirium; convulsions; hot, dry skin; strong and rapid pulse; and possible unconsciousness. Make no mistake: heat stroke can be fatal, and victims need immediate medical attention.
Prevention: The Best Solution
The number one method of avoiding heat disorders: avoiding heat. But for construction workers in the summer, this is simply not possible. So, here are some tips for staying cool and staying alive, beginning with the most obvious:
- Drink plenty of fluids. Your body needs water to keep cool. Drink water even if you don't feel thirsty. Proper hydration actually begins the day before a long, strenuous day in the sun. Before increasing your fluid consumption, consult a physician if you (1) have epilepsy or heart, kidney, or liver disease; (2) are on a fluid-restrictive diet; or (3) have a problem with fluid retention.
- Do not drink alcoholic beverages. Alcohol dehydrates your body. Enough said.
- Limit caffeine intake.
- Do not take salt tablets unless specified by a physician.
- Put less fuel on your inner fires. Foods that are heavy in protein increase metabolic heat production and also increase water loss.
- Dress as lightly as possible. You need protective clothing, of course, but consider light-colored fabrics, such as cotton, that breathe.
- When possible, take longer breaks than normal in a cool, shaded area. A rested worker is a more productive worker.
- Know the symptoms of heat illnesses. Use a buddy system to keep tabs on your fellow workers.
- Acclimate yourself to the heat. You can “get used to” the heat, to some degree. Workers, especially those who follow the advice above, can eventually develop some degree of tolerance. However, new employees and workers returning from an absence of two weeks or more should have a five-day period of acclimatization: 50 percent of the normal workload and time exposure the first day, gradually building up to 100 percent on the fifth day.
stopimg title="keepCool_img3" style="padding-left: 20px;" align="right" style="BORDER-BOTTOM: 0px solid; BORDER-LEFT: 0px solid; WIDTH: 260px; PADDING-LEFT: 10px; HEIGHT: 195px; BORDER-TOP: 0px solid; align: left" alt="keepCool_img3" src="/uploadedImages/Left_Nav/Press_Room/Job_Related_List/3_KeepCool_260x195.jpg" border="0" />Supervisor Obligations
There are precautions every employer should take when temperatures are high and the job involves physical work.
- Understand the signs of heat stress and permit workers to interrupt their work if they are extremely uncomfortable.
- Provide training about the hazards leading to heat stress and how to prevent them.
- If possible, schedule the heaviest workload for the coolest part of the day: early morning or late evening, when the sun is less intense.
- Make sure your workers have easy access to cool water—a minimum of one quart of water per hour, per worker.
- Schedule frequent rest periods with water breaks in shaded or air- conditioned areas.
- Routinely check on workers who are at risk of heat stress due to protective clothing and high temperature. Pay close attention to those who are at risk because of age and physical condition (including obesity and diabetes).
When A Fellow Worker Is Ill From The Heat
- Call a supervisor for help. If the supervisor is not available, call 911.
- Have someone stay with the worker until help arrives.
- Move the worker to a cooler/shaded area.
- Remove outer clothing.
- Fan and mist the worker with water; apply ice (ice bags or ice towels).
- Provide cool drinking water, if the worker is able to drink.

If your machine's hydraulic system isn't working, neither are you. Here are some common causes of hydraulic system breakdown and steps you can take to avoid them.
stopimg title="SK650_1" style="padding-right: 20px;" align="left" alt="SK650_1" src="/uploadedImages/Left_Nav/Press_Room/Job_Related_List/SK650_1stopimg4Contamination
An estimated 75 percent of all hydraulic system failure is due to contamination, so change filters regularly. If filters become dirty too frequently, examine them. Metal shavings can indicate that a pump, motor, or other upstream component may be failing. Resin or sludge—type material usually means oxidation of the fluid, often caused by low fluid levels or damaged seals.
Use clean tools and equipment, and always thoroughly clean hydraulic components before you remove, repair, or reinstall them. When you disconnect a hydraulic line, cap the end to keep contamination out while you're servicing the system. When you put the system back together, always install a new filter.
stopimg title="SK650_2" style="padding-left: 20px;" align="right" alt="SK650_2" src="/uploadedImages/Left_Nav/Press_Room/Job_Related_List/SK650_2stopimg4Low or Dirty Fluid
Low fluid levels can cause everything from sluggish cylinder operation to catastrophic pump cavitation, so check the fluid regularly (with the engine off and the fluid cool) and maintain the proper level. Always use the right fuel for your system.
Murky or cloudy fluid usually indicates water or air in the system. Water can come from condensation, and excess air can be a result of low fluid levels, a damaged seal, or a crack in a suction hose.
Other System Components
Sometimes the obvious causes of hydraulic system trouble get overlooked. Try these preliminary checks:stopimg title="SK650_3" style="padding-right: 20px;" align="left" alt="SK650_3" src="/uploadedImages/Left_Nav/Press_Room/Job_Related_List/SK650_3stopimg4
- Check the hydraulic fluid level with the engine off and the fluid cool.
- With the engine stopped, check for leaks around seals, castings, and hydraulic connections.
- Check for kinks in hydraulic lines.
- Check for a plugged or damaged fluid cooler or fluid filter.
- Check the electrical connections to solenoid valves. The problem may not be hydraulic after all.
When in doubt, you can always find factory—trained technicians at your Ditch Witch dealership, professionals whose only business is keeping Ditch Witch equipment healthy.
stopimg title="19a" style="padding-right: 20px;" align="left" alt="19a" src="/uploadedImages/Left_Nav/Press_Room/Job_Related_List/19astopimg4Take the time to winterize your equipment this year. A few minutes spent could save you time and money in the months to come. The amount of winter care your equipment needs depends both on the climate and how it is used. Check your service manual guidelines, and keep the following tips in mind:
1. Check coolant. Provide protection by using the recommended antifreeze/water mixture for the lowest temperature expected during operations.
2. Change the oil and filter before cold weather arrives. In addition, use lubricants recommended for low temperature applications.
3. Maintain the battery. Remove cables, clean cable ends and posts, and clean and tighten terminals on the cranking motor. And remember never to charge a frozen battery.
4. Check tire inflation. Tires inflated in a warm shop will be under-inflated when used in cold temperatures.
5. Give hydraulic components time to warm up before beginning work. If you’re running diesel equipment, be sure to idle the engine a few minutes before shutting down to properly lubricate internal components. Your local Ditch Witch® service technicians can help you make the most of your cold-weather equipment productivity, and can suggest winterizing techniques that are perfectly suited to your operation.
