HVAC air ducts have provided protagonists and antagonists means of escape, sneaky entrances, and surprise attacks in movies. While the scenes in these movies may not be completely realistic to real life standards, they’re still enjoyable and entertaining to watch. Below are a few scenes in which an HVAC air duct was used in a crafty way by movie characters.

Mission Impossible

Perhaps the most infamous scene from the Mission Impossible series is Tom Cruise’s character being lowered into the white control room at Langley. Given the tight security surrounding this mission, Tom Cruise’s character can’t simply waltz through the front door. The air duct gives him access from the ceiling to retrieve the information without triggering any alarms. During the scene we see his accomplice lowering him down from the safety of the immensely strong and study air duct above.

The Fifth Element

In this wacky sci-fi movie, an alien is transformed into a human female. After her transformation is complete, she’s completely bewildered, confused, and scared. In order to escape those trying to capture her, she leaps head first into an air duct. There she navigates the tunnels searching for a way out. This character also tries to escape through an air vent in the climax of the film, but soon realizes the vent is circular and there’s no way out. Needless to say, ventilation sure comes in handy when this otherworldly creature is looking for escape.

Alien

Alien is unique in that the antagonist (the alien) is the one using the ventilation system to navigate and surprise her prey. This scenario stretches the truth to its limit, since we can guess that the alien likely weighs near one ton and spits acid. These two factors combined make it highly unlikely that the alien could be properly supported in this fashion, but then again, it does make the film thrilling and suspenseful.

The Breakfast Club

The Breakfast Club inserted a bit of truth into their HVAC air duct escape scene. After rebellious character Bender is locked away in the broom closet for misbehaving, he escapes through the duct above the hallways. Once he’s over the library, where all the other students are, the duct caves and he falls through. Since most airways likely can’t support the weight of a human, this is the most realistic scene on the list. The collapse also provides a funny punchline for Bender’s unfinished joke.

Resident Evil

A group of agents enter an underground facility that’s been shut down due to a virus outbreak. Once the group realizes the virus has turned the dead into walking zombies, they scramble for a way to exit the underground facility safely. Navigating through hallways, laboratory rooms, and utility tunnels, the group finally makes their way through an air shaft to reach safety and evade the hungry zombies.

Though escape through an HVAC air ventilation system isn’t likely your best bet in real life, it makes for a thrilling and entertaining escape in movies. We’re likely to see many more sneaky crawls through airways to come in the future.

Genesis Air is a company based out of Lubbock, Texas. They offer air purification solutions for commercial applications but they also carry a few stand-alone units. Although we were unable to analyze all their systems, we were able to gather valuable data on their stand-alone systems. This information is revealing. Genesis Air systems rely primarily on photo catalytic oxidation (PCO) technology. These systems combine MERV filtration with PCO.

The Genesis Air 2008 RGS and the 2006 D&L cost between 99.6 cents and $1.21 per square foot of air cleaned per year. They cover between 750 and 3000 square feet. They cost between $3360.30 and $9077.67 to use over 10 years. They have an MSRP between $1400 and $5400.

These air cleaner systems are priced much higher than competitors in the marketplace. The particle efficiency on the MERV filters in these systems is only about 75% down to.3 microns in size. The company only backs these systems with a one year warranty.

These air purifier models seem to be very uncompetitive with similar models from other companies in the industry. The cost-benefit value of these systems is very poor. They are priced like high-end air purifiers but without offering the many benefits typically associated with top-tier systems. Some of these benefits one would expect to see in a system like this: the leading PCO technology in the industry, one of the highest particle efficiency removal rates in the industry, and one of the best warranties in the industry.

The bottom line is there are many options out there that are superior in all three benefit areas listed that also cost much less. So not only do competitor’s products perform equally well and in many cases better, they also cost much less.

One of the benefits of these systems is that they have the ability to be mounted. Although they are stand-alone systems, the MERV filtration in the system indicates that they are originally designed for being mounted close to the ventilation systems. These could be great systems for combining with a ventilation system to address odor, gas, and particle pollution. At the end of the day, the costs involved just do not seem to justify the use of these systems.

The OSHA Safety Standard Regulation 29CFR CHXVII Paragraph 1926.302(b)(7) states: All hoses exceeding 1/2-inch inside diameter shall have a safety device at the source of supply or branch line to reduce pressure in case of hose failure.

Prevent dangerous air hose whips and accidents. Protect your most important assets: Your employees and their equipment.

OSHA COMPRESSED AIR SAFETY SHUT-OFF VALVES offers simple but efficient protection to pneumatic systems in the event of a broken compressed air hose or pipe.

Saftey is what this is all about for you, your business and your employees. Don’t let a “mising” safety valve cause accidents. Make sure all your air hoses 1/2 inch and larger in diameter have the OSHA required safety shut-off valve.

_________________________________________________

Another OSHA guideline publication states: “Hoses, cables, and other equipment shall be kept clear of passageways, ladders and stairs.”

OSHA says reduce your slips, trips and falls.

Slips, trips and falls constitute the majority of general industry accidents, which cause 15% of all accidental deaths, and are second only to motor vehicles as a cause of fatalities.

The OSHA standard for walking and working surfaces apply to all permanent places of employment, except where only domestic, mining, or agricultural work is performed. ( from OSHA.gov )

Consider adding reels to increase safety & efficiency with your electrical cords, welding cables, air hose, oil, grease, liquid/water or fuel hoses. This could be one of your most effective equipment additions you’ll ever make… as well as one of the safest!

Reels are suitable for many applications – such as industrial, automotive, marine, chemical, welding, petroleum, food processing, aviation, and electrical.

Reels are used to transfer air, water, motor oil, transmission fluid, grease, gear oil, anti-freeze, diesel fuels, welding gases, fuel oil, liquid pesticides, fertilizers, detergents, hydraulic oils, cutting oils, printing inks, solvents, chemicals, and blacktop sealers.

Probably one of the largest uses of hose reels is for Compressed Air. Compressed air is clean, readily available, and simple to use. As a result, compressed air is often chosen for applications for which other energy sources are more economical.

Inappropriate uses of compressed air include any application that can be done more effectively or more efficiently by a method other than compressed air.

Don’t WASTE your Compressed Air. Check your facility for wasteful and perhaps even unsafe uses of compressed air.

Bottom Line: Invest in durable, quality reels that make hoses, cords and cables more productive, keep them easily accessible and make them last longer.

According to the US Environmental Protection Agency (EPA) indoor air can be five times more polluted than the outdoor air. As indoor air remains enclosed and not circulated as much as outside air, many pollutants tend to thrive inside, which increases the risk of respiratory infections, neurological problems, etc. for the occupants. Pet dander, pollen, dust mites, paint fumes, smoke released from cooking are some of the common types of indoor allergens that can deteriorate the air quality. Besides, lack of ventilation, dirty upholstery, and humid environments contribute to the harmful indoor environment, making children, aged population, and people with chronic conditions more vulnerable to numerous health issues. However, high-efficiency particular air (HEPA) filter can help to clean the bad indoor air by accumulating pollutants. It works to pull air into the machine at the base through a fan, the instilled filters catch the pollutant in the perforations, and the machine then releases the fresh air into the surroundings. A true HEPA filter can remove up to 99.9% of the dust particles, measuring as small as 0.3-micron diameter. Some types of air purifiers have charcoal filters that can absorb odors and harmful chemicals while others have UV filters that kill harmful microbes present in the surrounding air.

What makes one bowling alley better than the next? Some might say it is the acoustics, the music they play, the ambiance, or the fact that they let you smoke inside and purchase alcohol? Others might say it is the equipment, the quality of the furniture, or even the quality of the clientele on outside of town.

Still, what makes one bowling alley better than the next is usually the air-conditioning, that’s right, the air-conditioning system especially in the summertime. Of course, if the bowling alley operator truly wants to make money they can’t blast the air conditioning too much, or they will spend all their money paying for the electricity, and there won’t be enough left over to afford to keep their lease, or pay the salaries of all the employees.

Bowling alleys are actually part of the entertainment sector, one which got hit pretty hard during the recession, and thus, they compete with things like movie theaters, miniature golf, and even the smaller theme parks. If the price is right and the air-conditioned atmosphere is correct, the place will be full.

Bowling alley operators need to have dual air conditioning systems. They should use a swamp coolers for temperatures up to a certain point, and then a different kind of air conditioning system when the temperature reaches the maximum efficient point for the swamp cooler.

The air-conditioning system should also blow the airflow from the middle of the lanes into the area where people are waiting to bowl. This way people will wish to stand around where everyone is bowling causing more people to play, rather than just hang out. Also the room with any pinball machines, or electronic games ought to be well cooled and sealed off from the rest of the bowling alley.

By maintaining efficiency and climate control, a bowling alley can maximize its profits, by reducing its energy expenses. Please consider all this.

You expect your air bags to protect you from injury during an accident. You expect to be able to use your sun visor to shield your eyes from the bright glare of the sun. However, in some vehicles, the combination of deploying air bags and in-use sun visors can have dangerous consequences, including blinding you. This page describes those dangers in some of those vehicles.

The Accident

A young man was driving a 2003 Mitsubishi Eclipse in rural Texas. Because the sun was setting on the horizon, the passenger had her sun visor down to shield her eyes. As the car turned slowly into a Little League parking lot, its left front wheel struck a small post in the center of the driveway that had been obscured by dust kicked up by other cars. Despite the low speed, and despite the lack of any damage to the front bumper or front end, the air bags deployed.

As the passenger air bag deployed, it slammed into the passenger’s sun visor (sun shade), smashing it apart and sending it flying. As a result, our client was hit in the face and was blinded in one eye. The sun visor remained attached to the car by only a single strand of wire, since the air bag smashed it off its attachments.

The force from the deploying air bag was so strong, that it ripped a jagged metal insert from inside the sun visor right through the visor’s plastic shell. The force was also strong enough to shatter the vanity mirror that was part of the sun visor.

Given this dangerous interaction between the air bag and the sun visor, and given the devastating injury that it caused, it is not surprising that there was blood on the surface of the air bag.

Our Testing

To determine whether the passenger air bag was designed in a way that allowed it to rip the sun visor off during deployment when the visor was being used, we tested another 2003 Mitsubishi Eclipse at an independent air bag test facility. For the testing, we used both real-time video cameras and very sophisticated high-speed cameras. This high-speed video of the testing allowed us to capture the passenger air bag / sun visor interaction in great detail, and to clearly document how the air bag rips the sun visor off its attachments.

In every one of our tests, the passenger air bag smashed into the sun visor, ripped it off its attachments, and sent it flying through the cabin of the car, where it could pose a danger to the passengers.

Although this accident, and the testing we conducted, was in a 2003 Mitsubishi Eclipse, other cars are also at risk for the same danger. For example, our investigation has revealed the following cars sold in the United States all use the same or substantially similar passenger air bags and passenger sun visors as the ones we tested that demonstrated the danger:

o 2000, 2001, 2002, 2003, 2004, and 2005 Mitsubishi Eclipse

o 2001, 2002, 2003, 2004 and 2005 Mitsubishi Eclipse Spyder

o 2001, 2002, 2003, 2004 and 2005 Dodge Stratus

o 2001, 2002, 2003, 2004 and 2005 Chrysler Sebring

Other cars may use different air bags or different sun visors, but that does not necessarily mean that they are free from danger. For example, some other vehicles may also have a passenger air bag that deploys upward, along the windshield, and that can strike a sun visor that is being used. At the same time, some other vehicles may have sun visors that are not specifically designed to stay together after being hit by an air bag.

Change of seasons sometimes reveals problems with a vehicle that would otherwise go unnoticed. If you have a Jeep Grand Cherokee or a Ford Explorer that has an outside air leak behind the glove box, then you may have a broken fresh air door (AKA Recirculate Door or Max Door). The fresh air door is used to either recirculate air in the passenger compartment or allow fresh air to enter the HVAC (Heating Ventilation & Air Conditioning) system. Surprisingly the Explorer and the Grand Cherokee share a common flaw in the heating and AC system. The fresh air doors are weak plastic that many times under the stress of the control actuator can break. When it’s cold outside this problem makes itself very apparent. In hotter climates in the summertime, a broken fresh air door drastically reduces the air conditioning’s efficiency.

Checking it is easy by operating the fresh air door and listening for increased airflow. When the climate control setting is moved to max, the sound of the air blowing through the vents should be louder because the fresh air door is sealing off the outside air, forcing the inside air to recirculate. If the sound is not louder, you can open the glove box door and look behind it for the operation of the door when switching the setting from normal to max. If the door is not visibly moving, it is likely that it has broken. The door sometimes can even fall to the bottom of the case, positioned right above the blower. It may not be in sight, sometimes you can stick your fingers through the plastic grate and feel the door laying loose on the bottom.

Replacement of the door is not a do it yourself job. The dash needs to be swung out and the HVAC case removed on Grand Cherokees. On Ford Explorers the job can be done without the removal of the case, but the assembly must be replaced. Obviously if the case needs to be removed, the refrigerant must be recovered, which requires an ac machine. So if you are mechanically inclined the one that may be done at home might be the Explorer, of course this depends on your mechanical ability. Even if you are not going to do this job yourself, this information can be used to help explain to the repair shop what the problem is. By providing more information to lead the technician to the problem area, diagnosis time can be reduced.
