Today we introduce Jason Berry, Director & TreasurerJason Berry has been serving as the Director & Treasurer of BABFAR since the retirement of our founder Bruce A Berry, the BAB in BABFAR. Jason Berry appreciates being part of the BABFAR team, and that all employees can discuss their ideas openly. He thrives on working alongside the team to help each of their strength’s thrive. Born and raised in Massachusetts, Jason is extremely well versed in the unique climate of the Northeast and knows exactly what it takes to heat a variety of spaces. While he enjoys all aspects of his job, his favorite part is coming up with creative solutions to challenging issues. He loves the thrill of taking a seemingly impossible job and showing off the impressive abilities of BABFAR’s equipment. Jason’s career path into the temporary heating industry was fate, if you will. He needed a job with flexible hours to work within his college schedule, and BABFAR fit the bill. He was hired on as a yard guy and truck driver, and quickly grew to admire the company and their products. He took every chance he could to advance over the next ten years, and then the opportunity to become Director presented itself. When Jason is not at work, he can be seen enjoying quality time with his family. Coming from a mechanical background, he also enjoys working on classic cars and mountain biking, and hopes to tackle Whistler BC by bike one day. Jason is proud of all of his accomplishments at BABFAR, but especially proud of how he turned BABFAR around after the founder’s partner passed away. The company was surprised with hidden debt and at one point they almost shut down. But Jason and his family fought for the opportunity to turn BABFAR around. Jason has succeeded, and then some. He credits the incredible team he has assembled and knows that he couldn’t have done it without them. To Jason, the BABFAR team has become like an extended family. In the future, Jason hopes to continue to provide safe alternatives to the other harmful heating options out there. He strives to continue improving BABFAR’s equipment and raising the bar in the temporary heating industry. We will leave you with Jason’s favorite quote, which is appropriately applicable to BABFAR’s business model: “There is hardly anything in the world that someone cannot make a little worse and sell a little cheaper, and the people who consider price alone are that person’s lawful prey. It’s unwise to pay too much, but it’s worse to pay too little. When you pay too much, you lose a little money — that is all. When you pay too little, you sometimes lose everything, because the thing you bought was incapable of doing the thing it was bought to do. The common law of business balance prohibits paying a little and getting a lot — it can’t be done. If you deal with the lowest bidder, it is well to add something for the risk you run, and if you do that you will have enough to pay for something better.”- John Ruskin, Common Law of Business Balance
Wikipedia offers a simple definition of positive pressure: A pressure within a system that is greater than the environment that surrounds that system. Put another way, in a positive air pressure system, excess air will escape through openings in the system into the surrounding environment.
Positive air pressure is used in a number of applications. In hospitals, the system keeps airborne microorganisms away from patients. It’s also used to remove hot air from and deliver cold air to computers in data centers. In the construction world, positive pressure is a cost-effective way to distribute heat, provide a safe working environment, and remove moisture from enclosures.
Efficient Airflow, Efficient Heating
Installing temporary heaters on a winter project is just a start. If considerations are not made for airflow, heating will be ineffective and expensive. To heat a given space, especially one with obstructions like walls, attention must be given to how hot air is distributed.
To address heat distribution issues, some companies are quick to recommend installing additional heating units. But, this increases equipment rental, setup and fuel costs. Sometimes multiple units are placed inside an enclosure to reach problem areas. Yet, recirculating air raises safety concerns related to carbon monoxide and introduces moisture issues. Alternatively, fans are sometimes used to try to distribute heat. But, our own experience on hot summer days will remind us that fans are used for cooling! So this extra expense actually has an opposite, unintended effect. Without proper airflow, these approaches are little more than expensive, over-sized space heaters. Positive pressurization leverages simple physics to ensure proper airflow and distribute heat—eliminating the need for extra equipment.
Babfar recommends placing heating units outside an enclosure. If units are placed inside, make sure the unit draws outside air, to maintain positive pressure. This will distribute heat effectively. Air will take the path of least resistance. So, well-planned openings in the enclosure (cracked windows or cut-outs in a building tarp) will draw air to an area needing heat.
Air Change for Safety
OSHA’s recommended Permissible Exposure Limit (PEL) for carbon monoxide (CO) is 35 parts per million (ppm) as is the regulatory limit in the State of Massachusetts. A level of 200 ppm for several hours or more is considered dangerous.
Positive pressurization prevents carbon monoxide and other hazardous materials from reaching unsafe levels. An air change for a temporary enclosure should occur every one to two hours.
Defense Against Humidity, Moisture
As mentioned in our air movers post, a steady flow of fresh air is the best defense against humidity and moisture. Positive pressure is the key to maintaining airflow and preventing moisture buildup from causing project delays and damaging materials.
The last thing you should do is throw more heat at heat-related problems. Instead, improve the airflow! A positive air pressure system forces air into an enclosure and out through strategically placed openings. Designed properly, this system will improve airflow, evenly distribute heat within an enclosure, and ensure a proper air change.
Temporary heat is commonly used on construction projects in winter. Beyond the obvious benefit of keeping the work environment warm for employees and materials, it ensures proper air ventilation inside an enclosure. While heat is not required in summer, maintaining good ventilation is critical. Temporary air movers provide a safe work environment and keep your project on track during the hot, humid summer months.
