We’ve all done it- seen a crack in a wall or foundation and said “Eh, it’s just settlement” so we do not have to worry about it right now. But what is settlement, anyway? When does it happen, and why? Read More
I spent a decade of my career in the design engineering sphere. I loved my experiences there, and working in design has given me an understanding of how structures and their various elements are dreamed, designed, and constructed- how they ought to work as well as what can go wrong. Design is fun and can be complicated, and it does not need to be a big scary mystery. Let’s have a peek behind the curtain! Read More
I love spending time at the beach. Just this last weekend I drove by four fellows on extension ladders trimming palm trees with chainsaws on the side of the street.
Image of a worker performing ad hoc tree work without appropriate safety considerations. Of particular concern, his ladder is at an acute angle that puts undue strain on the frame and the worker has no secondary restraints to prevent him from falling off the ladder. Ladder falls are the most common injuries in the arboricultural industry.
Of course, anyone who knows me knows that one thing I like almost as much as the beach is talking about ANSI, OSHA and Read More
An 8-year-old girl was playing at a playground with her family. The playground was about a year old and very popular. While on the monkey bars about 7 feet up in the air, the child lost her grip and fell to the surrounding loose-fill material engineered wood fiber surface below. She hit her head and sustained Read More
Slip and falls occur when there is an unexpected loss of traction between a person’s foot and the walking surface, causing them to lose balance and fall. This type of injury is common and can occur in any setting where people walk, including homes, workplaces, and public areas. Slips can result in serious injuries, particularly for older adults.
The human gait cycle consists of four phases: the Read More
“What’s up man, you want to hit up the Longbranch tonight? Cool, I’ll get up with you later.” Ronnie ends the call and heads out on a beer run. After the last sip of Gin, Stan finishes up one of his many fan letters, drops it in the box, and starts to get ready for the night. “What’s good?” It was Ronnie’s cousin Squirrel on the line. “You okay with Stan going tonight?” “Yeah,” Squirrel says, “he’s got a sweet ride… we’ll let him drive! He let me drive that GT all last week, that thing is hot!” “Sounds like a plan! Let me go dude, bout to head in and get some cold beer.”
“911, what’s the nature of your emergency?“
“Yes, there is an overturned car, looks like maybe a Mustang, a red Mustang. I’m just off Highway 9. It’s down an embankment…I can see two people laying on the ground and one person still in the car. The two people on the ground are moving, but the one in the car looks bad!”
“Police and EMS are on the way ma’am.“
“Okay, I have my emergency flashers on, can you stay on the phone with me until they get here… it’s really dark and cold. I’m scared.”
“I’m here ma’am, try to calm down. Can you give me a description of the people involved, maybe what they’re wearing?“
“The one that’s lying near the car is wearing red jeans with a white T-shirt, and it looks like he has a black and green high-top sneaker on his left foot only, just a sock on the other. The other one out of the car has regular blue jeans on, and a green shirt with boots. It’s hard for me to see the guy in the car… looks like he has on jeans and some kind of black concert T-shit, I can see tour dates and make out the word “Shady”. Hey, the police are here, so I’ll hang up now.”
A lot is at stake here and we have quite a dilemma, three occupants involved in a single vehicle crash with one fatality and no idea who the driver is. The stakes begin to rise immediately, at the scene of the crash. What’s documented or not documented will affect the outcome of this case. It will affect the outcome of this case when everyone has gathered with suit and tie, when hands are placed on the Bible, and the truth is sworn to be told.
We’ve talked about proper collision scene documentation several times, but this time let’s talk about a few ways we can build a case like this and possibly identify beyond a reasonable doubt who was driving at the time of the wreck. Read More
As an experienced safety consultant, I am often called upon to investigate a wide range of premises liability incidents. One common type of incident that frequently results in serious injury is a fall on a painted walking surface.
The ASTM International Standard Practice for Safe Walking Surfaces, ASTM F1637, is a nationally recognized consensus standard that has existed for more than 30 years. It provides guidance to property owners and designers in the construction and maintenance of safe walking surfaces. The standard specifically addresses painted walking surfaces in Section 5.1.3.
ASTM F1637-21 states:
5.1.3 Walkway surfaces shall be slip resistant under expected environmental conditions and use. Painted walkways shall contain an abrasive additive, cross-cut grooving, texturing, or other appropriate means to render the surface slip resistant where wet conditions may be foreseeable.
In previous articles, I have discussed Read More
Stairs that contain three or fewer risers are considered short flight stairs according to safety standard ASTM F1637-21: Standard Practice for Safe Walking Surfaces. Single step transitions are also considered a short flight stair. Short fight stairs can be particularly hazardous for pedestrians due to the lack of visual cues signifying an elevation change. Unexpected changes in elevations can cause pedestrians to misstep and fall. Read More
Selecting the best or most effective way to reduce or eliminate risk from a particular machine hazard is an extremely important process. It can mean the difference between someone going home and hugging their wife and children…to never going home again. The hazard control hierarchy (see figure below) is an available tool that illustrates what is known to be most effective to least effective when it comes to eliminating machine hazards or reducing the risk from those hazards to an acceptable level. Removing the hazard by designing it out is by far most effective. Read More
Daylight saving (DST) ends on November 2, 2025, and with it the clocks will “fall back” an hour. While it is nice to gain an hour of sleep, the end of daylight-saving time also comes with a increase of vehicle crashes, injuries, and pedestrian fatalities. This phenomenon prompts the question: What is so dangerous about being a pedestrian at night? Read More
