Danger Lurking in the Hot Tub

Several dangers involving the use of a hot tub (spa) may readily come to mind, such as the risk of shock or electrocution, or the risk of drowning for unsupervised young children.  Not so readily apparent is the effect of overheating the human body, or “hyperthermia”.

Some individuals are more susceptible to the effects of hyperthermia, including the elderly, young children, and those in poor health.  The effects of hyperthermia, or overheating of the human body, cause direct responses such as headache, nausea, heat exhaustion, increased cardiac output, lethargy, confusion, heat stroke and unconsciousness.  The onset of hyperthermia is defined as being at 99.5° F; if the body temperature reaches 104° F, a life-threatening medical emergency exists.  Read More

Can you imagine framing a house with the tools of our forefathers, using hand saws and hammers, rather than power saws and pneumatic nail guns? Power tools have made the job much easier and faster, that even the amateur is well equipped for this kind of work. Read More

Jury Claims Swamp Cooler is Not Defective; Interlocked Guards are Not Required

An evaporative cooler, also known as a “swamp cooler”, is an air conditioner that works by evaporating water.   A float valve keeps several inches of water in the bottom of the unit. A pump takes water from the pan to the top of a series of vertical pads made of absorbent materials like wood fibers. The water flows by gravity through the fiber pads. A fan pulls hot air from outside the house through the soaked pads. Water in the pads evaporates, cooling the air and increasing its humidity. The cooled and humidified air is blown back into the house. Evaporative coolers need to be cleaned periodically. Read More

A portable electric generator should never be operated indoors, including garages, crawlspaces and sheds.

Winter Safety Tips for Portable Electric Generators

During winter ice storms, power to residences is often lost and homeowners revert to using gasoline powered portable electric generators.  It is often thought by some homeowners that leaving a generator outside in the severe weather may damage it or affect its performance and therefore resort to bringing the unit inside the shelter, typically, the garage. This is particularly hazardous when the generator is run for an extended period of time as carbon monoxide (CO) poisoning from the toxic exhaust gas can cause death. In addition, other hazards including electric shock, electrocution, fire and burns potentially can occur. Read More

In new water heaters, the combustion air holes have been replaced with a flame arrestor that lets vapors in but will not let the ignited vapors flash back to the pool of flammable vapors.

Preventing Fugitive Vapor Explosion with Design

For years, many water heater-related fires, injuries, property damage claims, and deaths were attributed to “consumer misbehavior.” By 2002, however, the NFPA National Fuel Gas Code began to reflect several key realizations: the existence of fugitive vapors and how appliance design can limit the risks they pose.

Are You Prepared to Adjust a River Flood?

Author

While working numerous Hurricane Sandy Flood Loss Claims in New York and New Jersey, I met many homeowners who didn’t understand the coverage limitations of their FEMA flood policy.  They were shocked, even mad, when they discovered some damages were not covered by the flood policy.  It pays to be prepared, courteous, kind, and tactful in responding to those adversely affected by any flood related event.
