Frequently, surveyors operate tools which, if not used correctly, could cause harm. Where there is a possibility that an eye injury could occur during the performance of assigned duties, surveyors should wear suitable face shields or goggles.
Steel-toe safety boots or high-top leather work boots should be worn.
Approved protective helmets mus be worn while working or visiting locations designated as "Hard Hat Areas". These helmets should be inspected on a regular basis and shall be replaced immediately if found to be defective. Helmets should be worn while working underneath overpasses and at any other time the foreman deems it necessary.
Wear high-visibility safety vests of approved color, or DOT yellow and orange rain coats, whenever working within the right-of-way, at any time when exposed to traffic such as
driveways, parking lots, construction sites, etc., and at any other time deemed necessary by the on-site supervisor. In addition, during night operations the safety vests should be reflectorized. If raingear or other outer garment is being worn the reflectorized vest should be worn as the outer layer.

Domain Dominance - Ben Janssen / Nexstep Article
Journal-Sentinel ArticleBen Janssen and his Appleton-based NexStep Inc. operate on a fairly simple premise.
"You don't have to remember who we are, you just have to remember what you want to buy," Janssen said. "That's our philosophy and it seems to be working out so far."
His company is built around product-specific websites and Internet addresses. "What we did was try to focus on generic, market-branded domain names," he said.
The business, which consists of six people and 25 websites, is growing and will be moving to larger quarters in Little Chute next month.
His storefront consists of websites. There is no brick and mortar and no geographic boundaries. That allows him to sell snow blowers to people in Russia and log splitters to people in Sweden. "Our customers are all over the place," Janssen said.
The company is one of many for whom the Internet has become the center of commerce, where barriers to entry are low, customer service is paramount and having the right combination of words in a Web page address drives customer traffic.
When torrential rains fell across parts of the Midwest and South this summer, NexStep's website waterremoval.com/">waterremoval.com saw business spike.
When tornadoes marched across parts of the South and Midwest this spring and summer - toppling trees like they were toothpicks - NexStep's logsplitter.com/">logsplitter.com saw traffic pick up.
And when heavy snowstorms shut down huge portions of the East Coast last winter, Janssen's snow-blower.com/">snow-blower.com sold out of its inventory.
"We're a distributor of a bunch of different lines of products and we have been for years," Janssen said.
His sites include chippershredders.com; gardentillers.com; hedgetrimmers.com; zeroturnmowers.com and lawntrimmers.com.
The brands he sells include Troy-Bilt, Earthquake and Mantis.
Doing business online
The company represents a continuing trend toward doing business online.
As sure as there was a dot-com bust a few years back, there are also business models that survived and are being embraced by consumers.
"There is much less reticence to purchase online," said Sandra Bradley, director of the University of Wisconsin E-Business Consortium's Web and multichannel marketing area. "As a matter of fact, there is the expectation of being able to purchase online."
Competition is everywhere. Then again, so are Janssen's websites.
"It's all competitive," he said. "The thing is, we don't have to be competitive in just one market. We don't have to rely on one geographic marketplace and we don't have to rely on one product line, per se.
"We're open for business to the entire world."
Convenience and customer service are crucial to a successful online business, Bradley said.
"Specialty or niche items are clearly a growing area for Internet sales in particular, driven by ease of being found," she said. "Consumers want convenience. They don't want to search hard. They want easy to use, easy to find."
Doing business on the Internet has become accepted practice, she said.
"We're the e-business consortium and we're in our 13th year. Every year we talk about dropping the 'e' because it really is just business. And it's not 'Web marketing.' It's just marketing."
Customer support
Janssen, 31, and a business partner started the company in 2003. He bought out the partner's share soon after that, he said.
"We were primarily into building websites for other people," Janssen said. Then, he said, he realized he could build his own websites and use domain names that he already owned as part of the business.
He currently owns about 680 domain names.
In building the company, he says he has learned a few things.
"The best thing to do is answer the phone," he said. "Customer support is the biggest thing in this industry.
"When they call, they want someone to answer the phone."
Day to day, "It's about getting the correct lines of products and working with the manufacturers and getting relationships going before you can actually launch a web site," he said. "That relationship between you and the manufacturer is really important, especially in this industry because it's so fast-paced.
"A customer orders, they want their product, they want shipping information right away and you get the order to them as soon as you can."
Business continues to evolve, he said.
"We're still growing. Every year we get a little bit bigger, " Janssen said.
"The real action, I think, is yet to be seen," he added.

Different Types of Surveying Instruments
Surveying equipment has been around since the times of the Egyptians, and only in recent years has the use of lasers been introduced to make the process of measuring things that much easier and simpler to achieve. There are many options available:
Laser Levels
The biggest benefit to be gained from using a self level laser over a manual device is that it can find its own level without the person having to make adjustments.
Single and Dual Grade Lasers
This kind of laser surveying equipment is used in order to measure as well as define the gradient of a slope. However the disadvantage of the single grade version is that it can only calculate what the gradient is on one particular plane whilst the dual version can do so using two different planes at once.
Rotating and Straight Line Lasers
The rotating laser produces a beam of laser light from a beacon which is able to rotate and so can produce a level plane right across 360 degrees. The straight line laser when used in surveying puts out either one or more laser beams and is able to perform the function which allows the surveyor to produce a cross or plumb line.
Pipe Lasers
This particular piece of surveying equipment is most often used when new pipes, drains or sewers are being laid (installed). Once one section of the pipe has been laid the laser will be placed inside it so the next pipe can be aligned and graded in line with the one already in place. Using this helps to ensure that the pipes being installed are done so with a great deal more accuracy.
Laser Receivers
This particular piece of equipment is often used with the laser level (which we have mentioned above) and is able to cover a much wider area of land that needs measuring. Also it enables the user to use the laser level both outside and when the sun is bright. The receiver works by being able to pick up the beam from the laser level and will adjust its height until such time as the right level has been found. As soon as this is achieved the receiver will emit a constant sound.
