As a result of the recent weather, those of us in South Carolina have gained a renewed appreciation of the damage that can result from flooding. Even a few inches of flood water can result in property damage and a loss of services in addition to the immediate risk of physical harm. Read More
In my June 2015 blog, I discussed a personal injury case where the jury decided that the lack of interlocks on the covers of a swamp cooler did not render it defective, even though it was technologically feasible to do so and their existence would have prevented the amputation. Conversely, in another interesting personal injury case involving a computer numerically controlled (CNC) milling machine, a large settlement was made by the manufacturer with the injured operator because the machine did not have adequate interlocks on its enclosure doors.

This is the third and final of three articles concerning the basics of air conditioning systems. This article concerns the evaporator, a part of the air conditioning system that is usually unseen inside the air handling unit. The evaporator, in concert with a fan, supplies cool air to a building interior. Read More
Industrial ovens and furnaces are used in many manufacturing processes. One use of industrial ovens is for drying and curing coatings on fabrics.
We investigated a fire loss involving a very large oven, 10 stories high, used for curing coatings on an industrial fabric. A young firefighter was burned in response to this fire, one of a string of many fires that had occurred involving the oven.
The condensing unit is a key component of all vapor compression air conditioning systems. We are all familiar with condensing units as the noisy exterior portions of air conditioning systems that blow hot air to the environment. Read More
Pressurized cylinders filled with various gases are very common, from the propane fuel tank under your barbeque grill to acetylene for welding to fluorine for production of many common products. A leak from almost any of these can cause damage or significant losses, from a fire to physical injury, or asphyxiation.
Owner protection against losses and injury can range from nothing to significant, such as storage in ventilated closets or gas detection alarms. In one case the regulator valve on a small CO2 cylinder used in a bar to pressurize beer kegs broke off. The cylinder rocketed around the bar room, causing at least one serious injury. Read More
Air conditioning systems are everywhere in our lives – at home, in our vehicles, at work, in manufacturing facilities – yet most people give them little thought other than setting a comfortable temperature until they stop working or malfunction in some other way. Read More
The North American Deck and Railing Association (NADRA) recognizes the month of May as Deck Safety Month®. This is the time of the year to get serious and take the necessary steps to safeguard your deck so that it is enjoyable not only for your family, but your friends and any visitors. The NADRA has a deck safety program and they just released a video in an effort to save lives and prevent injuries and to protect your family and friends. Read More
Many modern machines and processes are controlled by Programmable Logic Controllers (PLC’s). PLC’s are essentially computers that have the ability, properly connected and programmed, to interface with the outside world and control the actions of a machine like a robot or conveyor. The PLC has a processor for processing the user programmed logic, and also has input / output (I/O) wiring provisions for both analog (e.g. temperatures and pressure transducers) and digital (e.g. limit switches and indicator lights) devices.

As an experienced safety consultant, I have investigated many incidents in which a worker falls through an opening. The majority of these types of fall incidents have occurred at construction sites and most resulted in a serious injury or death. Read More
