As the holiday season nears, thoughts turn to wonderful home-cooked meals with family. Few things in life are more pleasurable than a traditional holiday turkey feast. Yet for an unfortunate few, holiday meal time can turn tragic if a turkey frying accident occurs. While fried turkeys may be tasty, many fire safety experts feel that the reward is not worth the risk. (more…)
“Was a dark stormy night as the train rattled on…” Anybody? 1985? Scarecrow? Come on… this was when Cougar was still a Mellencamp! Ok… it was called Grandma’s Theme… you’ll have to look that one up… but as I sat down to write this blog on the environment, that song kept running though my head. If you look it up, it will have a similar effect… just a little warning.
In our last installment of the 9-Cell Collision Matrix let’s travel down the wet, slippery slope of environmental factors that can contribute to car crashes, and maybe take a closer look at the things around us, at or near our crash scene that may reveal some important clues. (more…)
Murder, suicide, deceit, and intrigue… car crashes? You bet! In our next installment of the 9-Cell Collision Matrix let us dive a little deeper into the glue that binds all this together, the human element.

Let’s begin with the most basic human element at the root cause of car wrecks, our old friend inattention. Inattention… a vast word that encompasses many lackadaisical conditions. The daydreaming 16-year-old in math class, the radio knob turner, the back seat talker, the quarter pounder with cheese eater, and perhaps the most offensive, the cell phone user. All very dangerous behind the wheel, and one very dangerous to your future… as it turns out, you will always need good math skills… ask me how I know? Driving is of course a divided attention endeavor, (more…)
How far away from a hazard should you stay? Your parents or grandparents would probably have told you to stay far away, but what are you to do when a hazard is present, and you must work around or near the hazard? And what exactly is a hazard? ISO 12100 Safety of machinery – General principles for design – Risk assessment and risk reduction defines a hazard as a “potential source of harm.”
Where would a designer of a machine or product start if they wished to protect the user from a known hazard? Consensus standards are a great place to begin the quest for safety. (more…)
In a previous blog post, we began to delve a little deeper into the vehicle aspect of the 9-Cell Collision Matrix by taking a look at tires. Let’s now take a closer look at the very diverse and interesting topic of Event Data Recorder (EDR) data. (more…)
In my two previous blogs, we first discussed wet sprinkler systems (Wet), the most basic and most common fire system type followed by dry sprinkler systems (Dry), which are a bit more complicated. Ratcheting up another level, in this last edition on sprinkler systems, let’s take a look together at preaction and deluge systems. These can be complex and variable, so we’ll operate at the 30,000 ft level. (more…)
In a previous blog post, I gave an overall introduction to the 9-Cell Collision Matrix as an investigative tool used in collision reconstruction. Now let’s focus in a little at each element.
They are called car wrecks, after all…so let’s start with a more comprehensive look at the vehicle component of the matrix. This review of the vehicle before, during, and after the collision will highlight a few important factors but is not meant to be all-inclusive. So, let’s get started! (more…)
Across industry and construction sites, there are times when employees of different employers are working side by side, or at least on the same site at the same time. Some industry examples are when chemical plants have contractors on-site for routine maintenance or during process shutdowns for major overhauls or repairs. OSHA refers to these as multi-employer worksites. In December of 1999, they revised their citation policy which allows for more than one employer at a worksite to be cited for conditions that violate OSHA standards. (more…)
In my previous blog , I discussed the most basic and most common fire system type: wet sprinkler systems. The possible failure areas discussed with wet systems will also apply to dry sprinkler systems (control valves closed, obstructions, issues in the system, installation, or deficiencies with inspection, testing, and maintenance). Dry systems are even more prone to obstructions than wet systems, so close attention should be paid to that possibility. (more…)
Machine guards can be compared to the clothes we wear every day. Indeed, they serve a very important purpose. Imagine someone leaving their home on a fine, sunny morning wearing nothing but a smile. Wonder how far they will get through the day before things start going poorly for this individual?
There will be more than a few raised eyebrows and blushes when he stops into the local Starbucks for his usual morning double-dipped and whipped, chocolaty chip with a touch of pumpkin spice cappuccino fix. Good luck with that! Probably going to leave disappointed, empty-handed, and likely wearing handcuffs. This will be the beginning of a very long, very bad day for that individual. Had he recognized the risks associated with this type of behavior, and then put forth a little effort to cover up, he would have prevented many unfavorable and possibly life-changing personal and legal problems from ever occurring!
