Ultraviolet Personal Safety & Equipment
So understand that any structure absorbing this light can be damaged by this energy, for example note how sunlight exposure tans the skin while prolonged exposure fades or breaks down materials. The photons of shorter wavelength such as 302nm for example, carry greater energy than 365nm therefore, these shorter wavelengths have the greater potential for causing biological damage. These wavelengths can penetrate the eye or skin cells and can produce heating and energy related biological changes that will modify or destroy cellular DNA; this is among the reasons why some UV light sources are used for germicidal sterilizing applications.
The basic philosophy should be to avoid pointing any unshielded ultraviolet emitting source in the direction of people. When in doubt about routine exposures you can buy a UVP Radiometer to detect and quantify the ultraviolet exposure, even to detect exposures as apparently innocuous as sunlight! But there will be instances when working close to our ultraviolet emitting sources when accidental or routine brief exposures may occur; it will be best to be prepared and protect the people in advance of such instances.
The gift of the ultraviolet experience can be a wonderful way to start someone on the path to a new hobby or spark. It is particularly amazing to see how fast children can lean and progress, and all this with only a comparatively modest investment - after all, this only requires buying a UV lamp and finding or buying rocks. However, parents should use discretion when buying ultraviolet lamps or other devices for children; the parent must judge the maturity of the child and that of the child's friends before deciding to give the gift of the ultraviolet experience. Then the parent should take time to instruct the child never to look directly at any UV source. The child will progress faster and farther if the parent or helpful adult can share the hobby with him or her, while instilling good practices and disciplines of safety all along the way.
As amazing as it can be to explore the ultraviolet spectrum, this is not child’s play therefore:
Right: UVP ultraviolet safety eyewear stocked by Company Seven - Face Shield, Spectacle, Goggle (76,463 bytes). How Many Devices To Buy? Company Seven recommends our clients make it a protocol to order a minimum of two (2) UV Safety Goggles or two UV Saftey Spectacles with each order for any new ultraviolet emitting device. In this way if one safety device becomes scratched or lost then the other is in ready reserve. If you anticipate sharing access to the ultraviolet emitting device with others, including fellow employees or for demonstrations in a classroom environment then order the quantity of safety gear that you will expect to need, plus some extras too in order to plan for loss or damage. Which Type: Face Shield, Goggle, Spectacle? the type of safety gear selected* is not as critical as the quantity, but this choice too is important. These are a 'one size fits all' in that most of these safety devices will fit onto most adults. We recommend you keep an assortment of safety gear since not all models will fit everyone, although one of these three is likely to fit anyone who can not use the other two devices. Here are the pros and cons of each:

||
Con: This is the most sophisticated and costly of the devices, and takes up the most storage space. But overall this is the most accommodating of the UV safety devices.
UV Safety Goggles: this lightweight device slips over the head and incorporates an elastic strap band that encircles the sides and back of the head to keep the goggle in place.
Con: Goggles do not protect any area of the face that is not directly covered by the device; the nose and other areas of the face can be exposed to radiation. The goggle can accommodate people wearing prescription glasses although the pressure from the goggles on the temples of the glasses might become uncomfortable for some. When wearing these in sub-freezing environments the humidity from the eyes can fog the interior of the goggle.
Safety Spectacle: this lightweight device slips on just like a regular pair of prescription glasses.
Con: Spectacles do not protect any area of the face that is not directly covered by the device; the nose and other areas of the face can be exposed to radiation. The spectacles are open and do not protect the eyes from splashing liquids.
* Company Seven requires ultraviolet sources never be pointed in a direction to directly expose personnel. Furthermore, personnel must be completely covered when working in the proximity of ultraviolet sources of ≤302nm; this includes a Face Shield, gloves, long sleeve shirt, etc.
Ordering UVP Products
Company Seven stocks some of the more popular UVP lamp and cabinet products, and we accept orders for their other products by numerous means. You can also bring your UVP item to Company Seven for repair, or contact us to obtain user-serviceable items (bulbs, grids, etc.). The ways by which you may order products or parts are outlined at
Company Seven has not become convinced that on-line ordering is always beneficial for the customer, particularly when making a more complicated choice. While on-line ordering certainly is convenient and time effective for the merchant since they do not have to spend time with the customer, the customer is not always making the best choices when buying solely after reading what may be "propaganda" on line. The best ways to make the better choices are to either visit our showroom, or telephone 301-953-2000. This way you can obtain prompt and competent concise assistance which will address your particular needs and concerns.
