Explosion Proof Lights Can Save Your Life - How To Choose The Right One For Your Environment

Class 1, Division 2 lights are considered hazardous area lights, which generally means environments laden with pulverized dust, solvents and fumes. Class 1, Division 2 lights are required in grain silos, barges, sugar processing plants, paper mills, coal processing plants and grain silos where flash fires are a significant risk. The February 2008 explosion that incinerated an Imperial Sugar refinery, killing 6 people, in Georgia was the result of an ignition of sugar dust in a silo where refined sugar was stored before being packaged likely ignited like gunpowder. "The result was as devastating as a bomb. Floors inside the plant collapsed, flames spread throughout the refinery, metal girders buckled into twisted heaps and shredded sheet metal littered the wreckage. 'There was fire all over the building,' said Nakishya Hill, a machine operator who escaped from the third floor of the refinery uninjured but for blisters on her elbow."

Explosion Proof Lights Can Save Your Life - How To Choose The Right One For Your Environment

Explosion proof lights are generally what customers need when searching for intrinsically safe lights. These lights differ from hazardous area lights and are defined by the types of conditions to which their safety rating apply. Class 1, Division 1 lights are the safest lights, meaning that they can be used in confined areas with exposure to flammable vapors and gases. The petrochemical and marine industries usually require Class 1, Division 1 lights to inspect and clean tanks, clean fuel cells, turn around facilities, and so on.

The testing and certification of explosion proof lights is conducted within a lab environment. A chamber is filled with propane and the light is activated inside the chamber. If the light ignites the propane, then it fails the test. Secondly, the light itself is filled with propane and various variables are introduced to cause the light to explode. Combinations of tests similar to these are conducted in a controlled environment to determine the appropriate safety rating.

In this edition of Better Know a Light, we explore intrinsically safe lights and explosion proof lights. While the term "intrinsically safe" is often used to characterize explosion proof lights, this term applies to a very narrow choice of lights. Intrinsically safe lights are defined as lights that create no heat, no spark and do not produce static electricity when dragged. Most spotlights and flood lights produce heat and some kind of spark, thus most lights are not intrinsically safe. Some specialty lighting products based on fiber optics are coming to market shortly that will meet these ultra-safe specifications.

Safety ratings are based on several factors and generally the rating includes a group designation. Groups A,B,C and D are gas vapor related, including acetylene, hydrogen, benzene, hexane, naptha, acetone, benzol, lacquer solvents, etc. Groups D,E and F are specific to different types of dust. In general, Class 1, Div 1 are usually tested and rated for groups A-D. Given that is a more rigorous safety rating, it is assumed that Class 1, Div 1 will be sufficient for Class 1, Div 2 rated environments.

Customer Review: Excellent TV!
We ordered the TV via Amazon and even though shipping would have been free, I paid a little extra to have it delivered in 3 days because I feared the longer it stayed in the shipping process, the better the chances of it being damaged. Anyway, we are very happy with the TV. The distance from which you watch it is important. The best picture is from a distance of about 15' away. Any closer, and the picture isn't as great. But it's hard to go back to regular TV once you've watched it in HD. I'm hopelessly spoiled! The set up was EASY! I read reviews about how difficult it was to set it up, and that's bogus. It was very easy. Given, I am electronically inclined, but I think my husband could have set it up easily and he's a doof. Haha! The sound is great too, especially for built in speakers. I was scared to buy something this pricey online, because if something goes wrong, you're kind of screwed. But the entire process from purchase to delivery was perfect. I do recommend reading up on sellers though, before you decide to go for it. Read other customer reviews on the seller!!! I changed my mind on a seller last minute and paid a little more for the TV just because I had a bad feeling.
Customer Review: disappointed

Customer Review: LG 20" HDTV
Great picture quality for both HD and SD signals. Built-in tuners provide sharp detail for analog or digital over the air signals as well as cable signals.Speakers are better than expected but a home theater speaker system would provide more surround sound quality.Excellent energy efficiency using only 60 watts when on and an amazingly stingy 1 watt in standby mode.178 degree viewing angles makes for a sharp clear picture from anywhere in the room.
