An NHZ is a defined area of risk, within which someone must be protected against the prescribed radiation with the proper PPE and SOP, an LCA other is a defined area of control outside of which is perfectly safe. They are independent of each other- an LCA can be within an NHZ and an NHZ[…]
A non-beam hazard (NBH) is exposure not related to a beam of Photons, but nonetheless includes associated risks. Examples of NBH include: Electronic/electrical hazards such as supply/mains power, high-voltage stingers, and operating supplies Thermal risks which exist from extreme temperatures when working with cryogenic materials at the low end and targets exposed to 2000°C and[…]
A Laser Safety Officer (or “LSO”) is someone who is charged with being the point of contact for laser-related activities at an organization which designs/develops, manufactures/repairs, and/or uses lasers and laser-based products and processes. Because The Photonics Group addresses the entire field of Photonics, and recognizes other potentially hazardous Photonics sources, we refer to the[…]
Photonics Safety is the study and application of risk mitigation to Photonics technologies and includes Laser, Fiberoptic, UV light source, and flashlamp safety sub-disciplines.
Laser Safety is the study and applications of risk mitigation related to LASER technologies.
An LCA is a contained area within which laser hazards are contained and has access controls to preclude entry.
A NHZ is a defined area within which laser/Photonics radiation is hazardous and above Class I/1. It may or may not have physical engineering controls which preclude entry.

A Photon is an elementary particle- the quantum of the electromagnetic field including electromagnetic radiation including light and radiowaves. It has an invariant mass of 0 and moves at the speed of light in a vacuum.
