Pollen Can Cause More Than Allergies

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

Stan

“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

Cross Cut Grooving in Walking Surfaces

Author

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

The Silent Sentry – A Working Smoke Detector   

Author

In conversations with both friends and people I have met through emergency calls with the fire department, I often observed that a lot of people never give a second thought to that little lifesaver mounted on the ceiling or the wall of their home.  That little lifesaver is the smoke detector.

On average, a fire department responded to a fire somewhere in the United States every 23 seconds in 2024.  A civilian was fatally injured in a fire every two hours and 14 minutes Read More

Short Flight Stairs, Big Hazard

Author

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

Ice, Ice, Maybe…The Impacts of Freezing Weather on Plumbing Fixtures

Author

It’s that time of year again. Freezing rain, flurries of snow that don’t stick around, and mornings using a spatula to scrape dreaded ice off our windshields. I’ve lived in the south most of my life, and I know the combination of excitement and dread that my compatriots and I are likely to face during the winter months. Let’s face it, we may know how to cook pulled pork, but when it comes to freezing temperatures most of us don’t have much experience! Read More

You’re Just Not My Type – Part 1: Guards

Author

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

CHECK OUT THAT RACK! – The Importance of Inspecting Storage Racks for Proper Installation

Author

People have too much “stuff”. Manufacturers, retailers, wholesalers, and commercial enterprises all carry inventory of “stuff”, too. According to the Energy Information Administration’s (EIA’s) own statistics, in 2018, the US had over 17.4 billion ft2 of warehouse and storage. Growing from just 13 billion ft2 in 2012, warehouse and storage space is the fastest growing and now the largest use of commercial space in the US, overtaking office space for the first time in modern history.

 

Almost every one of those buildings contains storage racks. And this doesn’t include the mercantile spaces. You can go to a big box retailer and buy cereal from a lower shelf while pallets of grain or packaged drinks sit 20-30 feet above, waiting to be introduced to the customer.

There is no specific OSHA regulation for anchoring storage racks – Read More

Stop or I’ll Soot!!!

Author

Fire. Something about fire touches our brainstems…both good and bad!  Uncontrolled fire is terrifying and deadly to be sure.  But the controlled burning of wood at a campfire or in a fireplace in your home almost can’t be beat, to my mind! For that very reason, a fairly common amenity to houses nowadays is the gas log fireplace insert.

When not installed properly, these logs will generate soot. These soot particles can leave the fireplace and meander.  All. Over. Your. House.  Read More

The End of Daylight-Saving Time Leads to More Vehicle and Pedestrian Collisions

Author

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
