Thunder, Lightning & Earthquakes In Dubai For Window Cleaners

If the rain begins to fall in the middle of a job, the cleaners sometimes have to start all over again.
Weather that leaves UAE men swinging in the rain: Window cleaners who hang from ropes outside skyscrapers in Abu Dhabi and Dubai are constantly watching for change in the weather. "The last time we saw rain like this was a few years ago. In 2012 it only rained once. It's not the hard rain that cleans things, it's a muddy rain and things get even worse," said Alain El Tawil, the managing director at Gecko.

If the rain begins to fall in the middle of a job, the cleaners sometimes have to start all over again. Gecko cleaners were halfway through cleaning a building in Abu Dhabi when it started to rain. The job that should have taken 20 days will now probably take 30. "We have to do it again," Mr El Tawil shrugged.

Rain is not their only problem. Amel Vriesmann, head of the rope access division at Megarme, said: "We need to stay within the parameters of the winds. The limit is 20-25 knots depending on the scope of work you do. When the rain becomes severe, we pull out. But a few drops don't stop us."

Last week's thunder and lightning had cleaners abseiling down to safety. "Once we saw lightning, we were off the building. We have a daily weather forecast email among all the management. Rain is OK but thunder and lightning is a no-go," he said.



World's Highest Window Cleaners - It Took Us Three Months To Clean Burj Khalifa (Nick Vassilev) -  It took an Australian window cleaning company 3 months to clean the windows of the tallest building in the world - Burj Khalifa. Ever wondered about how they keep the windows of these skyscrapers clean? The usual options available to window cleaners such as ladders and high-level Reach and Wash cleaning systems aren’t an option there.

London, UK -- Travel and tourism websites, programmes and brochures continually bring us pictures of tall skyscrapers in some far-off land, man-made mountains of glittering glass and steel. But pause to think about what has to go on to keep the windows of these skyscrapers, such as the Burj Khalifa in the United Arab Emirates (UAE) sparkling and clean.

Usually, window cleaners working with exterior windows above the ground have several options. “We encourage our window cleaners to use high-reach window washers that can be operated from the ground for health and safety reasons,” said a spokesperson from the London-based cleaning company Anyclean, which offers window cleaning alongside a range of other cleaning services. “Ladders are OK if used correctly for two-storey houses and skylights on bungalows.  The Reach & Wash machines can reach up 75 feet, which takes care of most domestic and office window cleaning situations, but for anything higher than this, you need cradles, harnesses and cherry pickers.”

So what did the company responsible for keeping the windows of the Burj Khalifa clean do? The Burj Khalifa is the world’s tallest building at 2717 feet tall with a total of 24,830 windows, which make up 1,292,500 square feet of glass to clean.  The Australian company CoxGomyl, which is responsible for getting the windows clean for the opening ceremony (held back in 2010), took three months to complete the process of cleaning the windows.

This window cleaning team specialises in making equipment known as Building Maintenance Units (BMUs) as well as other high-rise high-tech window cleaning equipment. A number of these BMUs are permanently in place on the Burj Khalifa and the machines use a system of tracks and cradles to reach every single window. The tracks are built into the exterior façade of the building, and window cleaners are carried in these cradles (which are housed in special cavities inside the building when not in use) to where they can work at washing the windows. To clean the windows, they use ordinary soap and water. “You can imagine how expensive it would be if they used chemical window cleaning products,” said the representative from Anyclean. “But water does work well at cleaning just about everything.”

The window cleaners who operate in the highest BMU on the Burj Khalifa hold the current record for world’s highest window cleaners.  “Good for them,” said the Anyclean representative. “But I think I like keeping my feet on the ground!”

909 high-rises, 448 skyscrapers in Dubai... But do you know how to survive an earthquake? Tall order: Dubai has 909 completed high-rises, including world’s tallest tower, tallest hotel and tallest residential buildings (By Vicky Kapur) -  Two major earthquakes have rocked the Arab world and the UAE in the month of April: the first one on April 9, and the second one on April 16. Both the earthquakes were follwed by minor aftershocks. A 6.3 magnitude earthquake shook Iran and the rest of the Arab world at around 4pm UAE time on April 9, 2013, followed by smaller aftershocks. The death toll from the quake was last reported at 37, with hundreds others injured, mostly in Iran.
 
The epicenter of the April 16 quake, of 7.8 magnitude, was also in Iran, near the border with Pakistan, and it rocked the region at 2.44pm UAE time (10.44am GMT). The UAE's official seismology authority, National Centre of Metrology and Seismology, confirmed to  Emirates 24|7 that the epicentre of the most recent quake was 650km off the coast of Ras Al Khaimah in UAE. However, the tremors from the quake could be felt in locations as far and wide as Dubai, Abu Dhabi, Doha, Manama, parts of Saudi Arabia as well as in Oman, with minor swaying of high-rises reported in these locations.

Earthquakes are not common in Dubai and the rest of the UAE, but nature has its way of showing who’s the boss every once in a while. Perhaps because we are not used to experiencing frequent tremors, residents of Dubai and Abu Dhabi, especially those living and working in high-rises, may not necessarily be adept at knowing what to do when tremors strike. It is no secret that Dubai is home to the tallest residential skyscraper cluster in the world. Not only does Dubai boast of the tallest building in the world, the imposing Burj Khalifa, but also the tallest residential tower (Princess Tower), the tallest hotel in the world (JW Marriott Marquis Dubai), among many more.

According to Emporis, a global provider of building information, Dubai has 909 high-rise buildings , including 448 skyscrapers (comprising 40 floors or more). According to SkyscraperPage.com, Dubai has 387 towers that are more than 99 metres in height, of which 84 are more than 202 metres tall and 26 are 301 metres or more in height. Indeed, there are three towers in Dubai that are at least half a kilometre (500 metres) in height. That’s a tall order, indeed, if there was one.

While we’ve all come to live and love our high-rises in Dubai, we can’t all claim to know about what do in case an earthquake strikes. Proof of this was the recent Iran quake, tremors of which were felt by us here in Dubai. There was confusion all along, with a number of office and residential buildings evacuated on the one hand, and with others going along with their daily chores as if nothing had happened. But if you need to be prepared the next time tremors strike, wherever in the world you are, you’ll do well to understand the following pointers (SOURCES: Earthquake Country and Go Los Angeles.

INDOORS: DROP, COVER, HOLD ON…

• DROP to the ground; take COVER by getting under a sturdy table or other piece of furniture; and HOLD ON until the shaking stops. If there isn’t a table or desk near you, cover your face and head with your arms and crouch in an inside corner of the building. Check out this PDF .

• Stay away from glass, windows, outside doors and walls, and anything that could fall, such as lighting fixtures or furniture.

• Quickly move to a safe location in the room such as under a strong desk, a strong table, or along an interior wall. The goal is to protect yourself from falling objects and be located near the structural strong points of the room. Avoid taking cover near windows, large mirrors, hanging objects, heavy furniture, heavy appliances or fireplaces.

• If you are cooking, turn off the stove and take cover.

• Stay in bed if you are there when the earthquake strikes. Hold on and protect your head with a pillow, unless you are under a heavy light fixture, window or anything else that could fall. In that case, move to the nearest safe place (i.e. under a desk or in an inside corner).

• Use a doorway for shelter only if it is in close proximity to you and if you know it is a strongly supported, load-bearing doorway. Brace yourself on the side with the hinges to avoid the door swinging at you.

• Stay inside until shaking stops and it is safe to go outside. Research has shown that most injuries occur when people inside buildings attempt to move to a different location inside the building or try to leave.

• Be aware that the electricity may go out or the sprinkler systems or fire alarms may turn on.

• DO NOT use the elevators, even if they are working. There may be aftershocks.

• If you’re in your hotel room, stay there. There are usually aftershocks, and sometimes they may be worse than the original earthquake. Under a sturdy desk or in an inside corner of your room is the safest place to be, even if you’re on the 40th floor. If there’s a heavy bookcase next to a match-stick desk, don’t get under the desk.

• If you are in a restaurant, get under the table.

OUTDOORS: Stay Put

• Move to an open area where falling objects are unlikely to strike you.

• Move away from buildings, powerlines, streetlights, utility wires and trees.

• Once in the open, stay there until the shaking stops. The greatest danger exists directly outside buildings, at exits, and alongside exterior walls. Ground movement during an earthquake is seldom the direct cause of death or injury. Most earthquake-related casualties result from collapsing walls, flying glass, and falling objects.

TRAPPED UNDER DEBRIS

• Do not light a match.

• Do not move about or kick up dust.

• Cover your mouth with a handkerchief or clothing.

• Tap on a pipe or wall so rescuers can locate you. Use a whistle if one is available. Shout only as a last resort. Shouting can cause you to inhale dangerous amounts of dust.

AFTER THE QUAKE

• Check for injuries, attend to injuries if needed, help ensure the safety of people around you.

• Check for damage. If your building is badly damaged you should leave it until it has been inspected by a safety professional.

• If you smell or hear a gas leak, get everyone outside and open windows and doors. If you can do it safely, turn off the gas at the meter. Report the leak to the gas company and fire department. Do not use any electrical appliances because a tiny spark could ignite the gas.

• If the power is out, unplug major appliances to prevent possible damage when the power is turned back on. If you see sparks, frayed wires, or smell hot insulation turn off electricity at the main fuse box or breaker. If you will have to step in water to turn off the electricity you should call a professional to turn it off for you.
