Cameras need constant care and attention to keep in optimum operational condition. They generally require daily attention if you are traveling and even more in adverse conditions. Here is a guide to help care for your camera when conditions become extreme.

Extreme Cold

Carry your camera equipment in a hermetically sealed metal case; a complete seal is important. Gaffer tape can be used as a sealant against fine snow and is effective down to -10 degrees C. Take great care when touching metal parts especially with the face. Skin sticks to frozen metal and can be torn off to remove; this is extremely painful.

Try to keep your equipment at a constant temperature as much as possible. Relocating into a warm room straight from the cold causes condensation to form. When taken outside again the moisture freezes on contact with sub zero temperatures. Both the moisture and ice in your camera will almost certainly cause problems. A way to avert this is to put your equipment in separate sealed plastic bags with packets of silica gel. Examine your camera design thoroughly by means of a photography course online and learn how to deal with the issues of extreme conditions and the impact on your camera equipment.

Extreme Heat

Ground temperatures in many deserts can exceed 50 degrees C. Cameras and associated equipment left in these temperatures can become untouchable. In addition direct sunlight on a camera may melt the cement and glue holding components in place. Today, many metal parts have been replaced by plastic; these can also melt under these temperatures. Keep equipment in silver colored cases to reflect the sun away from your equipment. Clean and maintain your equipment at night when its cool. A camera wrapped in chamois leather at night will stay cool well into the day.

High Humidity

The tropics give high humidity and this is also a major problem for camera equipment. Moving between air-conditioned buildings and the outside humid, damp air fogs glass and takes a long time to clear. Keep all equipment constantly outside rather than inside is best if possible. In the damp heat fungus grows on many materials used in your camera. Small insects may decide to make your camera home.

After returning from a trip to India my Nikon SLR metering system failed. I subsequently sent it off for repair. The camera was returned with a note saying a family of spiders took up residence. They were alive all this time and feeding off fungus. Sealing your camera in a plastic bag is the best way to prevent this from occurring. Learn about the impact of humidity on camera equipment through a respectable photography course online and take the appropriate precautionary action.

Excessive Dust

This is a huge problem for SLR cameras particularly if you use prime lenses and changing them frequently. Dust gets inside and makes its way to the sensor and stays put. It can be extremely difficult to remove if not impossible. You may have to send the camera away for professional cleaning and this is expensive. Gone are the days when a blower brush would get you out of trouble. Keep your camera in a well sealed bag when exposed to dust. Consult a reputable photography course online to find out the specifics of your cameras controls and design.

Sea Water

Salt water and even sea air can cause permanent damage to your camera equipment. If you are working in a sea side location you need to take precautions. The best protection again sea water damage is good insurance and a water proof housing. If your camera falls unprotected into sea water, the best thing to do is to throw it away and buy a new one. It will be utterly ruined. If you wish to try and salvage the camera, rinse it thoroughly in clean water and take it immediately to a professional repairer. I have been able to salvage mechanical cameras this way, but with electronic it’s much more difficult.

By taking the precautions mentioned here you will be able to avert the many problems that adverse conditions present. This is important to you as high quality cameras are expensive and are vulnerable to the elements. Examine your camera design thoroughly by means of a photography course online and learn how to deal with the issues of extreme conditions and the impact on your camera equipment. Reduce these risks and enjoy years of use from your cameras and lenses.

Guangzhou, Ministry of Justice, manager Chen Yong said the offer Gree 17.07 million yuan has been a reasonable profit, while the successful units offer higher than Guangzhou Geli out of more than 400 million, is entirely profiteering. “The government procurement should be on technology to protect the case to save money, but now they not only purchase expensive to buy right, it is difficult to understand.” The Guangzhou City Finance Bureau, Zhang Jieming, said in an interview in Guangzhou Geli high-profile prosecution of the enterprise act as a government department are not going to respond. However, he said with a smile, Gree took the opportunity to exert pressure on the government, is to use the media hype. Successful companies do not normally offer? According to Chen Yong introduced, companies will normally offer in accordance with industry practice, in the case of guaranteed profits in the price ceiling based on the rate to fall 10% to 20%. The Central Hospital of Panyu District, Guangzhou, bidding projects, several other successful businesses, including small to float downward, but remained at the same rate to fall within the range. Chen Yong said that Guangzhou Geli’s offer routinely to float downward, while a handful (including the successful enterprises) to float downward only a few points, some even float downward only 1% ~ 2%. “The successful tenderer the price of business enterprises, the second highest in the bidding, with the price ceiling is very close to, in general, government procurement tendering is a very unusual phenomenon.” Chen Yong said, “Gree skill, a marketing company’s after-sales service guarantees, an edge than the general agent of the circumstances, Gree also sought a preferential price of winning the bids. Instead, an agent (referring to the successful enterprises) reported that close to the price of a price ceiling, not knowing where their confidence comes from. ” The Financial Secretary said that speculation Gree Prior to this, “Daily Economic News” interview with the Guangzhou Bureau of Finance agent, the agent said that while the price for air-conditioning to queries raised by relevant evidence, but all the other post-judgment say. Guangzhou City Finance Bureau, Zhang Jieming in an interview said that there is inconvenient to comment on the case is still pending. He said that the Guangzhou City Bureau of Finance of the Government Procurement Center is responsible only for monitoring, Gree event business has nothing to do with the Finance Bureau. Government Procurement Center is bidding companies to court is not the first time, but the widely advertised Gree only. Procurement of people also to come Panyu Central Hospital, confirmation of the “Daily Economic News” reporter said, “because of this event has entered the legal process, the hospital no comment.” That do not want to be named in the legal profession said that if the tender documents Gree does have problems, that the “Feibiao” is normal, but successful businesses in advance in accordance with standards Gree “find fault” might have been tricky, a. “Every air-conditioning businesses are not the same technical parameters, some stressed that the quiet, some stressed that energy-saving, and if it so bad to elect said.” As for this “Feibiao” case involved in the project, successful enterprises to adopt the US’s air-conditioning, and Gree level of technology should be relatively close, then the crux of the matter is that in the case more or less technical level, the Gree bids, whether there is sufficient to constitute “Feibiao” flaws? So the procurement people prefer to spend more than 400 million? From a disclosure situation, the experts are also difficult to conclusion, and only had to wait for court decisions.

McGill University Researchers find Sanuvox UV Purifiers to destroy 99% of microbial contamination that may cause Sick Building Syndrome

Author: Anonymous
Source: free-articles

Montreal, Canada August 26, 2004 — In a study published in The Lancet Medical Journal, McGill University scientists found that shining proprietary Ultraviolet Purifiers manufactured by Sanuvox Technologies Inc. on the air conditioning coil reduces over all sickness by 20%, reduces respiratory symptoms by 40% and has resulted in a 99% reduction of microbial and endotoxin concentrations on irradiated surfaces within the ventilation system.

According to the study’s leader, Dr. Dick Menzies of the Montreal Chest Institute โ€œUltraviolet germicidal irradiation, or UVGI, has been used to disinfect the air in hospital operating rooms and ventilation systems as well as meat-packaging plants and the pharmaceutical industry.โ€

Sick building syndrome has often been blamed for irritation of the eyes, throat and nose as well as respiratory illnesses such as asthma. Symptoms also include headaches, fatigue and problems concentrating. By reducing microbial contamination using Sanuvox Ultraviolet Purifiers, McGill researchers hoped to see a corresponding reduction in the levels of work-related illness.

After studying the effects of Sanuvox UV CoilCleaners in three Montreal offices over a period of 48 weeks, the researchers found it had a “substantial effect in reducing reported work-related illnesses.” Menzies said.

A total of 771 employees from three different public and private buildings in Montreal were involved in the double blind study sponsored by the Medical Research Council and The National Institute for Occupational Safety and Health (NIOSH). Starting in 2001, the patent-pending Sanuvox UV CoilClean Purifiers were turned on for four weeks, then turned off for 12 weeks. The cycle was repeated three times for a year. The use of the Sanuvox UV Purifiers resulted in a 99% reduction in the concentration of bacteria on irradiated surfaces within the ventilation systems. Temperature, humidity and ozone levels were unaffected.

โ€œSanuvox uses specific UV wavelengths to destroy biological and chemical contaminants in the air-stream and on the air conditioning coil. This study illustrates very well how our process destroys microbial contaminants. By using Aluminum Parabolic Reflectors, the Coil Clean purifiers are able to direct 100% of the UV Energy onto the coil without losing UV on the back-end of the lamp. The Reflector also protects plastics and wiring from destructive UV rays. This is how Sanuvox is able to deliver a high concentration of UV intensity to the air conditioning coil virtually eliminating and preventing any future growth.โ€ Said Dr. Normand Brais, President of Sanuvox Technologies Inc.

Wladyslaw Jan Kowalski, an architectural engineer at Pennsylvania State University’s Indoor Environment Center, told The Associated Press the McGill study may be a landmark in proving the technique could be cost-effective in commercial office buildings.

Dr. Kowalski, who was not involved with the research, also said the approach could be useful in the broader effort to combat contagious diseases such as flu, SARS, tuberculosis and cold viruses.

“Theoretically, if a large number of schools office buildings and residences were modified, a number of airborne respiratory diseases could be eradicated by interrupting the transmission cycle,” he said. “Reducing the transmission rate sufficiently would halt epidemics in their path.”
