A worker was injured while testing gas springs similar to the type that hold the hatchback of an SUV open. The hazard that injured the worker was an unguarded shear point. The tester contained a mounting plate that was raised and lowered by a pneumatic cylinder.
The pneumatic cylinder lowered the mounting plate while the worker’s fingers were in the hazardous, unguarded shear point. Read More
While on a lunch stop during a recent vacation trip through Tennessee, I happened across a safety hazard that required immediate attention. The establishment had a raised concrete patio at the front with a steel railing around the perimeter. At one edge of the patio was a set of stairs with a continuation of the steel railing used as a handrail. The top edge of the patio had light strings wrapping the top metal bar as accent lighting for the perimeter. The light string continued down the stair handrail wrapped in the same manner as the rest of the patio. Read More
Equipment and appliances supplied with fuel gases like natural gas, propane and butane are a common and convenient part of most of our lives. Such devices as gas grills and ranges, ovens, furnaces, space heaters and water heaters usually perform without incident. However, when they malfunction the potential for incidents such as fires and explosions, carbon monoxide (CO) poisoning and burn injuries may occur. These incidents may be due to design and manufacturing defects in the product, or improper installation or operation of the device.
Several dangers involving the use of a hot tub (spa) may readily come to mind, such as the risk of shock or electrocution, or the risk of drowning for unsupervised young children. Not so readily apparent is the effect of overheating the human body, or “hyperthermia”.
Some individuals are more susceptible to the effects of hyperthermia, including the elderly, young children, and those in poor health. The effects of hyperthermia, or overheating of the human body, cause direct responses such as headache, nausea, heat exhaustion, increased cardiac output, lethargy, confusion, heat stroke and unconsciousness. The onset of hyperthermia is defined as being at 99.5° F; if the body temperature reaches 104° F, a life-threatening medical emergency exists. Read More
Welcome to the third and final post in our multipart series of blog posts about a young boy’s fall and serious injury at a public playground. In our first post we gave a brief overview of the incident and our investigation. In the second post we discussed some of the safety standards applicable to public playgrounds. In this post, we will examine some of the impact-absorbing playground surfaces available to protect children at playgrounds from injury. If you would like to read the first two posts, they are available here and here.

A 5-year old boy was severely injured at a public playground when he fell through a second floor opening around a fireman’s pole in a playhouse. He fell more than seven feet and struck a bare concrete floor. We are thankful that he eventually recovered from his injuries. The person who designed and built the playground was accused of negligence. A lawsuit ensued, and eventually settled in favor of the boy. Read More
A blower used to exhaust air from an industrial process stopped functioning when the blower wheel drive shaft fractured. The process, and thereby most of the plant, had to operate at a reduced volume until the blower wheel could be replaced. The blower wheel had been installed during a shutdown a week before the incident. The blower wheel was a spare installed when the existing blower wheel was sent for scheduled remanufacturing.

A large agricultural trailer had been connected to a truck using a clevis pin with a spring locking clip. The trailer became disconnected from the truck and collided with an oncoming vehicle. The trailer was in poor condition, did not have safety chains, and had substantial recent modifications by the owner. Read More
In May, 2014, a plant farm worker was seriously injured when he fell into the hopper of an electrically powered soil mixer. The mixer in question used a rotating steel ribbon powered by a 7-1/2 hp electric motor to mix batches of materials such as sand, mulch, wood shavings, fertilizers and other landscaping materials to create potting soil. At the top of the hopper sidewalls, within 6 inches of the ribbon, was a steel grate. Read More
