Selecting the Proper Fixture for Applications with Exposure to Chemicals

Certain chemicals that may exist in end-user locations, release airborne contaminants that can impact the integrity and safety of key fixture components. Examples of these components include, but are not limited to, lamp holders, lenses and latches that contain acrylic or polycarbonate material.  Damage may occur, such as crazing, cracking, permeation losses and mechanical failure. Products with visually noticeable deterioration have diminished integrity and must be replaced immediately with a more suitable product for the application.

Please remember that all environmental factors should be considered when assisting with the selection of indoor fixtures and solving application issues. This is especially important when working with relight applications and new customers. We recommend that the following steps be taken prior to placing an order:

§  Request end user’s material safety data sheets (MSDS).

§  Compare MSDS with list of most common chemicals found on www.lithonia.com for compatibility. (This list is also contained in the Product Selection Guide(s) but may not be current as to recent revisions. It is recommended that you review both the online and printed tables when selecting product.) The direct link to the electronic table is: http://www.acuitybrandslighting.com/Library/LL/documents/specsheets/Acrylic-Polycarbonate-Compatibility.pdf.

·         This list identifies the most common chemicals and is not intended to be all-inclusive. Exposure to compounds identified as “Not Accepted” will void all warranties associated with the product. Acrylic or polycarbonate components should not be used in areas where these chemicals are used and where these chemicals become mists or airborne vapors.

§  Obtain end user sign-off of final fixture selection.

As always, if you have any questions or need final verification, please contact your factory representative for assistance.
