Recently, Digital Trends profiled a Paolo di Trapani, and his work has a lot of people excited. For all the rapid progress that has been made with LEDs, no one else has made this important step towards recreating natural light.

The article explains how lighting innovations have allowed people to use artificial light in a number of amazing ways. We can change the color temperature of a light bulb with a smartphone, and we can grow food indoors, but we haven’t yet been able to mimic the way the atmosphere scatters the sun’s natural light…until now.

According to Digital Trends, di Trapani’s technology scatters the light of a panel of white LEDs with “a clear plastic panel studded with nanoparticles that are invisible to the naked eye.” What’s a nanopartical? A nanoparticle is what it sounds like: A really small particle. Nanoparticle research is currently hot because there are tons of ways that nanoparticle research could be applied in biomedical, optical, and electronic fields.

According to OSHA, “Safety related work practices shall be employed to prevent electric shock or other injuries resulting from either direct or indirect electrical contact.”  *   This OSHA rule helps to enforce national guidelines regarding  Arc Flash Protection.

The type of protective outer wear worn depends on the level of flash risk. While working in the lowest risk levels, personnel must wear flame-retardant clothing. The level of protection gradually increases to include rubber gloves and other specialized clothing.  As the  level of risk increases employees must don a specified number of layered, flame-retardant clothing under a multi-layered flash suit complete with hood and gloves.

*OSHA 29 Code of Federal Regulations (CFR) Part 1910, Subpart S

The Denver electricians at Piper Electric Co., Inc. regularly perform arc flash studies in accordance with OSHA regulations to determine the degree of danger involved in industrial settings. The analyses are performed as a means of understanding and preventing possible arc flash hazards. In keeping with National Electrical Codes and OSHA requirements, an electrical engineer surveys the breaker panels, fuse panels, panel boards and switch panels along with motor control centers and panels in the facility. Following the evaluation and calculations, each location receives an ANSI arc flash warning label.  This marking can be generic or very specific, whichever is more relevant. Future revisions of the NEC standard may require more detailed information on this label.  At minimum the label should contain enough information to determine the area where conditions exist that only qualified workers should enter.
