Understanding Heat Transfer: A Guide for Fire Investigators

In the realm of fire investigation, understanding heat transfer is crucial. Heat transfer plays a significant role in how fires start, spread, and ultimately, how they can be analyzed and investigated. There are three primary modes of heat transfer: conduction, convection, and radiation. In this article, we’ll delve into each of these modes and explore examples of how fire investigators can apply this knowledge to their work. Read More

Hot ’til It’s Not Part II – Heating System Maintenance

Author

As cold weather sets in for those of us that actually get a winter in the Northern Hemisphere, a property owner needs to think about another expensive home system that is often taken for granted, your HVAC system.

Whether you have a heat pump with electric backup, a gas fired furnace, a fuel oil fired furnace, or even  electric strip heat, your heating system requires some routine attention to maximize efficiency and get the most life out of the unit.

As a homeowner, the easiest and cheapest thing you can do to maximize the efficiency of your heating system is Read More

Hot ’til It’s Not…Water Heater Maintenance

Author

An often overlooked item in your home’s infrastructure is the water heater.  Most people don’t think a lot about their water heater until they turn the tap and are surprised with water that is less than hot.  Water heaters are just like many other major home appliances, they need a little attention to get their maximum life and performance.

Surprise Slip and Slides  

Author

Falls were the number one cause of preventable non-fatal injuries and the number two cause of preventable deaths in the US in 2019 (CDC and NEISS data). Slip and falls occur when there is an unexpected loss of traction between a person’s foot and the walking surface.  Slip and falls are common and can occur in any setting where people walk, including homes, workplaces, and public areas. Slip and falls can result in serious injuries, particularly for older adults.

The human gait cycle consists of four phases: Read More

Differences in Slip Resistance of Materials used in Walking Surfaces

As an experienced safety consultant, I’m called on to investigate a wide range of premises liability incidents. In any slip and fall investigation it is important to assess the type of walking surface material involved and its corresponding slip resistance.

Slip resistance is a critical factor to consider when choosing the right flooring material for any space. It’s especially important in areas that are prone to moisture, spills, or other hazards that could make floors slippery and dangerous. A slip-resistant surface can help reduce the risk of Read More

Wire ropes are critical components of cranes and play a crucial role in ensuring the safety and efficiency of crane operations. To extend the life of these ropes and maintain their strength and performance, it is essential to regularly lubricate them. Read More

One of the Most Amazing Compounds Around – Water?!?!

Around Christmas day of 2022, a mass of very cold air settled in the deep south/southeastern United States (where I live).  It remained below freezing for over 24 hours.  That is very unusual down here.  There was a spate of burst pipes all over the area.  Why?  Water is one of a very few compounds that expands when it freezes…by approximately 9%!!  If a volume of water is sealed off in a section of piping, and that water freezes, it is likely the pipe will rupture. Then, when it warms up again and thaws, liquid water will leave the pipe for an adventure!! Read More

Improperly Used Space Heaters Can Be Dangerous

Author

As the temperature outside slides from the cold to the “bitter” cold range on the thermometer, most people tend to turn the heat on inside their home. Some homes, however, do not have whole house heat or sufficient heating capacity and therefore the occupants  may rely on portable space heaters. Portable space heaters, used properly, can be a good choice to warm a small area of a home. Unfortunately, while they can warm your cold and tingling hands and feet, they can also warm nearby materials to the point of ignition. Read More

If There is a Human, There are Human Factors

Author

If there is a human involved in the case, there is a good chance that human factors theories and principles will be applicable. Human factors is the study of people interacting with their surrounding environment. A human factors expert applies their knowledge of human capabilities and limitations to each unique case to assess the physical, sensory, and cognitive factors that caused a person to behave a certain way within the surrounding environment.

Consider the following situations in which a human factors expert would be beneficial: Read More

Everybody Has A Part to Play – What’s Your Role?

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.
