Accidents: Identifying Root Causes

Originally published 11/18/2015

Accidents and injuries create stress, and people react differently to stress. When accidents occur, a supervisor should take charge, and make sure everyone involved receives medical attention, if needed. They should also evaluate the area, identify potential problems that need to be addressed and limit access to the area to prevent further damage or injury. Once the situation is under control, the supervisor should begin the process of evaluating what happened and why it happened. The goal is to prevent a similar incident from happening again. To do that, you must understand the root cause of the accident.

Root-cause analysis is the process used to determine the cause of an incident, and come up with steps to prevent it from recurring. The process includes collecting information, charting or describing what happened over a fixed timeline, determining the root cause and finally, determining and implementing steps to prevent a similar incident.

Defining root causes:

  1. Root causes are underlying causes. The more specific an investigator is about why an event occurred, the easier it will be to arrive at a recommendation for prevention.
  2. Root causes can reasonably be identified. Occurrence investigations must be cost beneficial. It is not practical to keep valuable manpower occupied indefinitely searching for the root cause. Structured root-cause analysis will allow you to get the most out of the time invested in the investigation.
  3. Root causes can be influenced or controlled by management. Investigators should avoid listing general error classifications, such as operator error, equipment failure or external factors. These are not specific enough to allow management to make effective changes. Instead, identify specifics such as the following: Did this incident involve a new employee? Did he have sufficient training? Was the equipment faulty? Had it been tagged? Was it reported? Had it been regularly inspected and maintained? Were employees fatigued? Stressed?
  4. Root causes are those for which we can generate effective recommendations. If the investigator suggests a vague recommendation such as, “improve adherence to written policies and procedures,” he probably has not found the root cause of the incident, and needs to expend more effort in the analysis process.

Safety is everyone’s responsibility. Find and understand the root cause of an accident or injury, outline the steps necessary to prevent similar incidents in the future and communicate that information to everyone on the worksite. Give everyone the tools necessary to create and maintain a safe work environment.

Hurry: A Barrier to Safety and Productivity

Originally published 11/25/2015

There are many times during a typical work year when workers face the “Hurry-Up Syndrome.” As the deadline looms, workers sometimes ignore good practices for the sake of saving time. But all too often, hurrying to complete a job results in poor work quality or worker injury.

What happens when you rush to finish a job?

  1. Planning suffers. We place too much emphasis on action, rather than planning and thought. Instead of planning ahead and obtaining the proper tools and equipment to do a job correctly and safely, there is a tendency to make do with what you have. Using the wrong tool for a task can injure people and damage equipment. Without proper planning, we often stage materials far from where we will use them. This results in more movement, which increases the opportunity for an accident or injury to occur.
  1. Attention to task suffers. Workers don’t focus on the task at hand. Instead, they are thinking about what still needs to be done and the time deadline. This lack of focus can cause accidents and injuries. Distraction is often the root cause of injury.
  1. Breaking the rules. Looming deadlines can prod workers with the best of intentions, to break the rules in order to complete a task. They respect the procedures for quality work and the safety rules, but in the stress of the moment, they decide cutting corners just this once won’t hurt. An example would be when a worker fails to use the appropriate fall protection equipment because he only intends to be at a certain height for a few minutes. If there is no immediate negative consequence, then he has the tendency to repeat the action. Sooner or later there will be a negative consequence, which could result in damage to or loss of equipment, or cause injury to himself or others.

We cannot totally avoid the “Hurry-Up Syndrome;” however, we can acknowledge the stress for what it is and resolve to do what we know is best for both timely work completion and safety for our co-workers and ourselves.

Be Prepared for Cold Weather

It’s getting colder, and winter is just around the corner. Now is the time to think about the extra safety precautions you need to take during the winter months, whether driving or working on the jobsite.

Check out these tips for driving in winter weather:

  • Give yourself extra time to drive to work.
  • Use extra caution on bridges and overpasses. Remember that they will freeze first.
  • Drive defensively. Watch out for drivers who may be driving too fast for road conditions, or who may have lost control of their vehicle.
  • Measure the low-temperature protection provided by the antifreeze in your vehicle to avoid frozen radiator and hoses.
  • Keep an ice scraper, shovel, jumper cables, a blanket and some sand, kitty litter or traction mats in your vehicle.
  • Check the tread on your tires. If it’s less than one-eighth of an inch, consider replacing the tires.
  • Check the air tanks on your truck, and make sure liquid isn’t building up. During winter months, air brake lines could freeze because the air tanks weren’t drained. Driving a truck under these conditions is very dangerous.

Dress for working in cold weather:

  • Wear layers of clothing. Many layers of thin garments trap heat better than a few thick ones. You can always remove a layer if you get warmer.
  • Wear a liner in your hard hat.
  • Wear headbands or hooded jackets to protect your ears.
  • Keep clothes clean and dry.
  • Wear water-resistant boots.
  • Wear windproof outer layers.
  • Wear cotton close to the body.
  • Wear gloves with liners, if possible.
  • Wear an extra pair of socks for added warmth.
  • Make sure your safety vest is clean and in good repair. As the days get shorter, early low-light conditions make it very difficult for passing drivers, equipment operators and other co-workers to see you.

When possible, consider taking additional precautions against cold weather:

  • Take breaks in warm areas.
  • Use approved warming devices. Be cautious of carbon monoxide buildup when you are indoors.
  • Use the buddy system, and check on each other regularly.
  • Be cautious of ice buildup on the jobsite. Slip and fall injuries can occur suddenly.
  • Schedule work to avoid being exposed to high-wind conditions.
  • Work with your back to the wind.

The best time to prepare for the cold is before you are exposed. Think ahead, and be prepared for changing conditions. Following these steps can lessen your chances of an accident or injury.

Rigging Safety

Originally published 11/04/2015

Failure to properly secure static loads for transport causes injury to people and damage to property. When securing a load against unwanted movement during hauling, employees should use the same rigging techniques for tie-down as for lifting. The consequences of rigging failure during transport can be just as disastrous as dropping a load during a high crane lift.

The quality of the rigging equipment is important. Rigging materials such as chains, straps, hooks, eye bolts and clamps are not required to meet the same standards as similar gear used for lifting. However, when using come-alongs, strap winches and other tightening devices, the strain on rigging materials can begin to approximate lift strain. When the strain on equipment caused by tightening is combined with the strain of a truck when turning quickly, climbing a steep grade or making sudden stops, the strain on equipment can equal that of lifting, and cause rigging to fail.

Most chains used for hold-in-place rigging are grade 70. While these chains are very strong, they do not meet OSHA standards and are not safe for overhead lifting. Chains that are rated for lifting are typically SGG grade 100 chains. It stands to reason that a 70-grade chain is more susceptible to wear and tear than a heavier grade chain.

To ensure safety, inspect all tie-down equipment before use as follows:

  • Test chain links for stretch and breakage.
  • Inspect hooks for deflection at the throat and twist.
  • Inspect eye bolts and other terminating attachment points for wear and deflection.
  • Test tie-down points on the truck or load surface for wear and damage.

The same procedure should be used for straps and other tie-down equipment. If the equipment shows extreme wear, don’t use it.

Additional tips for load management include:

  • Place lighter items at the bottom of the load so that heavier items can help hold them down.
  • Block items against each other, or bundle them together, to minimize shifting and movement.
  • Lay tall items flat in the truck bed or trailer, when possible.
  • Block the wheels of equipment to prevent rolling. Wrap straps around and through wheeled equipment to further secure it.
  • Cover items with a solid, waterproof tarp to prevent damage from rain and airborne debris.
  • Tag all load corners with red flags if the load extends four feet beyond the bed of the truck or trailer.

Well-secured loads provide safety for your employees as well as the motoring public.

Safe Use of Cut Saws

Originally published on July 19, 2016

Construction workers often need to use cut saws to cut pipe, concrete, brick or block. Kickback – when the saw jumps back toward the operator – is the primary cause of serious injury when using a cut saw. Because cut saws are very dangerous, operators must have the proper instruction and training, and be regularly assessed to make sure they know how to safely operate the saw.

You should be in good physical shape and well rested if you are going to use a cut saw. Fatigue can cause you to lose control of the saw. Before you use the saw, familiarize yourself with the manufacturer’s instructions, and never use an abrasive blade on objects for which it was not intended.

When using the saw, hold it firmly with both hands, maintain good balance and footing at all times and avoid using the saw in awkward positions. It is important to position the saw in such a way that you are not bending over or standing directly behind the blade, especially when the guard is pulled back towards the top of the blade. Never overreach or hold the saw above the line of the shoulder.

A kickback can be caused by using the upper part of the cutting blade, or if the wheel is pinched at the front. It can also happen when a cut is interrupted, or when putting the blade back into a cut that has already been started. Material that sags or moves during a cut could bind the wheel or cause a kickback. Make sure that the object you are cutting is fully supported, secured so it cannot roll or slip and does not vibrate. Wet cutting not only helps keep the abrasive cool and reduce dust, but in a pinch situation, the water can act as a lubricant and reduce the energy of reactive forces. The saw’s guard should be designed to prevent cutting with the front and upper quadrant of the blade. You should never pull the guard beyond the limit stop.

A blade lock in can be caused when the work piece shifts, pinching the blade. Make sure that the work piece is clamped so that this can’t happen. You can also cause a lock in if you try to cut too deeply too quickly, or try to cut on a radius. These can lock the blade or cause the diamond segment to pop off. It would be safer to make a shallow guide cut, then come back for a deeper cut.

General safety tips for using a cut saw include the following:

  • Inspect the saw for damage before use, and make sure the guard is in place and secure. Do not use a wheel that has been dropped.
  • Wear the proper personal protective equipment – i.e. eye/face protection, non-slip gloves, ear protection, hard hat, long-sleeved shirt and long pants (but they should not be loose fitting), and a respirator when dusty conditions exist.
  • Fuel the saw outdoors in a well-ventilated area while the engine is cool.
  • Establish a safe work zone to ensure that no one is exposed to any risks because they are too close to the saw while it’s in use.
  • When finished using the saw, turn off the engine and let the wheel stop rotating before carrying the saw or setting it down.
  • When carrying the saw, be sure the hot muffler is on the side away from your body.
  • Store the saw in a cool, dry place. Abrasives are heat and moisture sensitive.

Cut saws are valuable tools in construction, but they can also be dangerous. Safety is one of the most important issues you need to consider before picking up a saw.
