“Shotgun Fred’s Guru Crew” The Walk to Defeat ALS!!!
Fred Pirkle, aka “Shotgun Fred”, founded ThermOmegaTech® in 1982. Since then he has patented more than 20 products, including the first temperature control device for charcoal grills/cookers – hence “The BBQ Guru” was born in 2004.
In April 2011, Fred was diagnosed with ALS. As his friends and family are well aware, he is a fighter and continues to fight the disease every day. In Fred’s honor, and in an effort to help support patient service programs and ALS research, ThermOmegaTech and The BBQ Guru have joined forces with the ALS Association. We are a corporate sponsor of and have formed a team, “Shotgun Fred’s Guru Crew”. On Saturday, November 5th we participated in our first Walk to Defeat ALS.

The International Plumbing Code, 2006, paragraph 701.7 reads, “Wastewater when discharged into the building drainage system shall be at a temperature not higher than 140°F (60°C). When higher temperatures exist, approved cooling methods shall be provided.
Freeze protection valves are effective in preventing freeze damage in process lines. Unlike steam or electric tracing, which require power and can cause water to overheat, freeze protection valves operate by simply draining or bleeding water as the temperature approaches freezing.
This prevents the formation of ice that can clog lines, shut off flow, and cause pressure within the line to build, cracking pipes, valves, and fittings, as well as dam- aging equipment. Damage due to ice formation can incur costs for replacement parts and labor, and reduce productivity due to shutdowns.
Nonetheless, freeze protection valves do not necessarily completely prevent the formation of ice. In some cases, ice may still form as a layer on the inside of a pipe. This actually acts as a good insulator, reducing further heat loss to the cold outside air. Also, if the ice does not completely block the pipe or equipment flow area, no damage will occur. Damage due to freezing is caused when a pipe or flow passage in equipment is completely blocked. Then, as additional ice forms, the expansion associated with the ice formation compresses the water and causes a dramatic increase in the internal pressure in the line. When the pressure exceeds the strength of the pipe or housing, these will break.

Circuit Solver from ThermOmegaTech, Inc.
Circuit Solver is a self-actuating thermostatic recirculation valve which automatically and continuously maintains the end of each domestic hot water supply line at the specified water temperature. This simple inline valve completely eliminates the need for time consuming and expensive manual balancing procedures and equipment. By allowing only water that actually cools below the setpoint to flow to the return, Circuit Solver also eliminates the need for oversized recirculation pumps which cause pipeline erosion and waste energy.
1. Water flows to the path of least resistance.
2. Many buildings require multiple branches off the hot water supply line.
3. Hot water use is hyper-dynamic, so the path of least resistance constantly changes.
4. Manual flow control valves cannot properly resolve these issues.
Install a Circuit Solver Valve on each hot water supply branch line immediately downstream of the last run out to a hot tap.

Australia has the highest average amount of solar radiation of any continent, making it the perfect place for generating power or heating water with energy from the sun. Not surprisingly, the combination of generous rebates and sunny weather has given rise to solar thermal installations across the continent. Generally these installations are quite straightforward, but in the southern part of the continent, temperatures can drop below zero (Celsius), causing freezing problems for some thermal systems.
OSHA Standard 1910.151(c)
Need a refresher on the OSHA standard for safety showers and eyewash stations?
Will OSHA cite a facility for not following the recommendations as stated in ANSI standard Z358.1-1990? Specifically, will an OSHA inspector cite a facility for not supplying tempered water to an emergency eyewash and shower?
Imagine the following scenario: One of your plant floor employees has just had their eye or skin exposed to a caustic chemical, which needs to be immediately flushed from contact. Per OSHA regulations, you should already have an eye washing station or emergency shower on the plant floor, which the employee should be familiar with. In an instant, they need the proper water, at precisely the correct temperature, to prevent scalding or escalating the issue any further. Can you be sure that your employees are safe in a washing emergency?
It could be the temperature inside your enclosure.
Are your enclosed instruments under the weather? It might be time to check the temperature inside the enclosure. Enclosures protect instrumentation against adverse weather conditions or physical damage, and ensure that instruments operate in the proper temperature ranges. However, enclosures may not always provide sufficient protection against temperature extremes that can affect instrument performance. High temperatures can cause some fluids to vaporize, while low temperatures can cause some lines to freeze or some products to thicken – even damaging sensitive equipment. For many instruments, the correct temperature of the instrument and sample will affect measurement accuracy. The best way to solve this problem is to equip enclosures with systems designed to maintain interior temperature within the range specified for optimal instrument performance.
The most common systems used to keep enclosures warm involve steam or electricity – essentially using an outside heat source to keep equipment in the enclosure at a predetermined temperature. Electrical heating can take several forms. Typically, a radiant heater or heating cable is installed inside the enclosure. A thermostat is used to control temperature or the cable may be self-limiting. However, electrical heating has limits. In large installations, the electricity required can be ex- pensive. If combustible substances are present, the possibility of electrical sparks poses risk. And, if the cable breaks, everything beyond the break could freeze.

Keeping your safety shower working at optimum performance is important, no matter what time of year. However, cold winter temperatures can make this especially difficult. Water can freeze in supply lines, clogging the system and shutting off flow. And because water expands as it freezes, internal pressure in the line can increase enough to break steel pipes and their associated valves and fittings. The result can be costly replacement parts, in- creased labor costs, and a shower that’s out of commission while it’s being repaired.
Cold weather can bring other problems, too. Water that’s too cold can discourage workers from using the showers for the full 15 minutes as recommended by ANSI and OSHA standards, thereby contributing to worker injury. Although federal regulations such as OSHA’s 29 CFR 1910 do not mandate every detail of safety shower systems, they do specifically require safe work- place conditions. Unless you provide comfortable water for safety showers, these regulations can be easily interpreted to result in safety violations.
There are a number of steps you can take to prevent cold weather from interfering with safety shower performance. Many are relatively simple to implement and can be readily put in place before cold weather begins.

Facts About Water Freezing
Water, when it freezes, changes from liquid to solid. As the temperature drops, the molecules become less energetic, moving more slowly, until they reach a point at which the molecular structure changes, followed by the transformation into ice, or solid water. Unlike most substances which shrink in volume as they freeze, water expands since ice’s molecular structure takes up more space than water. Conversely, when you heat water, the molecules become more excited until they reach the point where the water vaporizes and becomes steam.
There is a misconception that if water can be kept moving, it won’t freeze. Wrong! Water freezes at 32°F (0°C). Period.
Since the expansion of water as it freezes is a fact of life, what things should we know about this process in order to create effective means of dealing with it in industry? Water that has frozen in piping systems does more than simply clog the system and shut off the flow. Because ice takes up more room than liquid, when freezing occurs in a confined space like a steel pipe, the ice will build up extreme internal pressure which is often enough to break the pipe and its associated valves and fittings.
