During a commercial inspection of a small 65 year old building the Superior Inspection Group based out of Cookeville, TN discovered this fire place damper completely rusted out. The rain cap was damaged allow water penetration into the fireplace. The damper was completely inoperable due to the rust.

Read the articles on crawl spaces and it's your job to break it. On the issue of crawl spaces, I couldn't agree more about the dangers encountered. I have come across snakes and spiders, as well as black mold. Almost every crawl space inspection I've done there have been numerous wires on the ground and some with the dryer exhaust terminating in the crawl space where lint is hanging everywhere. As far as doing damage during an inspection, I have not thought about like it's our job to break things, but if they break during normal operation during the inspection, I write it up as defective.

I completed reading two articles for the course.

Smoke Alarm Inspection

I learned that 23% percent of time after a fire with fatalities it was found that the smoke detectors had been disabled. Probably due to low batteries not being replaced and producing the intermittent beeping sound.
And that there are 3000 fatalities a year from residential fires.
Most of the fatalities are a result of smoke inhalation.


Adjustable Steel Columns

I learned that no more than 3" of the column screw should be exposed.
The plates should be mechanically fastened at the top and bottom.
Maximum lateral displacement should not exceed 1".

Upon inspection of the basement in an approximately 100 year old building in Baltimore it was noted that there was no fire wall in place between the properties basement and the adjoining properties basement.
Certainly this can allow fire to spread easily between the properties and can allow carbon monoxide to enter if the adjacent properties furnace or water heater venting system failed.
It was recommended that a licensed contractor correct this situation.

Assignment...

Upon the initial perimeter walk around I noticed a sink hole near the foundation. It appears not to be new. The ground around the hole seems to be fairly solid, although not knowing the depth and extent of the opening below ground it's probably advisable not to get too close.
I would suggest further investigation by a foundation specialist.

HVAC unit mounted on a flat roof on a commercial location. This is a somewhat typical for a commercial application, a unit with the compressor and air handler together. Noted the system in place was in excellent condition. However, as the interior of the space was only roughed in, the ductwork stopped just inside the ceiling. This allows the new tenant to set up the system as required for their operation and layout. The compressor did show evidence of a previous repair on the refrigerant tubing. I believe a leak had been brazed. Additionally, as the sun in this area is intense, the nomenclature mounted on the exterior of the unit had faded to the point that it was almost unreadable. If the client had requested specifics on the HVAC system a serial number and some research would have been needed to acquire missing details. As the power was off to the space an operational check was not possible.

Read the articles, 'Commercial Real Estate Terms Inspectors Should Know'
by Nick Gromicko and Kate Tarasenko, and 'Drones and Inspections'
by Nick Gromicko, Thomas Zachar and Kate Tarasenko.

Found 'Drones and Inspections' an interesting article. Had not considered the usefulness of drones for the inspection of structure. Drones would be likely to provide an excellent alternative to walking a roof; thus improving inspector safety and limiting the potential for damage - unless you crash your drone ; )

More information on the FAA rules and a timeline for the small business can be found at http://fortune.com/2015/03/24/faa-co...rone-approval/ . According to the author of this article though some new blanket approvals have been granted, but unfortunate only for the limited number of companies already approved for commercial use.

Inspecting the water heating units of a rental townhouse, I found them to be in new and in good working order. The access is sufficient and marked off with caution tape, so as to guide anyone not to step off the walking surface and onto the ceiling drywall board. The water heaters each hold 40 gallons and are plumbed in serial fashion to give the tenets an 80 gallon net capacity.

Summary of two articles from the InterNachi library.

Wood Decay -

Wood decay generally falls into two categories - brown rot and white rot. Brown rot is distinctive by the cube shapes it leaves the wood in. White rot is literally white from the spores of the fungi. Wood decay is active at temperatures of between 77 and 90 degrees Fahrenheit, along with a moisture content of around 27 to 30 percent.

Drones-

Drone technology is here now and ready for commercial use. Unfortunately the FAA, which has been tasked with creating the regulations that control commercial drone use, is far behind in completing their assigned task. Hone inspectors are experimenting with drone technology, but doing so is illegal and carries stiff penalties. The conventional wisdom right now is to not use them in the inspection business.

The above pictures show a receptacle that was arcing. Fortunately the homeowner was home and shut off the power before it could start a fire. Good reason to upgrade to AFCI breakers to prevent this.

The first article I read for this class was C.L.U.E. Reports. "Comprehensive Loss Underwriting Exchange is what ti stands for. I never knew that this existed before and would definitely start recommending the buyer get one before the final purchase. No sense in buying the house if you can't get it insured for less than a small fortune.

The second article I read was Commercial and Home Inspector Carcinogens on the Job. This one was interesting to me because it actually stated that formaldehyde is a known cancer causing agent. I remember in high school Biology class we had to dissect a bunch of stuff preserved in formaldehyde. Sheesh! Even a popular brand of juice that claims to be "all natural" setteled a $9 million lawsuit for using calcium pantothenate, which is produced from formaldehyde.

Recommended seismic securing straps, drip pans, and copper TPR-valve discharge tubes to terminate no more than 6" above the concrete floor.

From course:

What is an expansion tank?

An expansion tank is a metal tank connected to a building’s water heating appliance designed to accommodate fluctuations in the volume of a building’s hot water supply system. These fluctuations occur because water expands in volume as it gets hot and loses volume as it cools.

Expanding water volume in a closed system can create dangerously high water pressure. As water is forced into the tank by expansion, it compresses air contained inside of a rubber bladder. Air is used as a cushion because it exerts less force on its container than water, which cannot be compressed.

The function of this bladder is to prevent air from becoming absorbed into the water, a process that could cause the expansion tank to lose its ability to act as a sort of shock absorber. If, over time, the bladder begins to leak some air, a Schrader valve, identical to the fill valve found on bicycle and car tires, can be used to add more air.
