Introduction
Topics covered:
Nominal Hazard Zones at LLO
LVEA Entrance
PSL Enclosure
Laser Diode Room
OSB Optics Lab
HPLF Optics Lab
VEAX Entrance
VEAY Entrance
There are several slides here that are intended to familiarize people with the laser safety measures that exist at LLO. Danger signs, status signs, locations of card readers, laser safety eyewear, phones and cameras are each shown in the LLO designated nominal hazard zones.

“Facility Access” permits access to office buildings.
“Facility Access” does NOT permit access to any nominal hazard zones.
“Zone Access” permits access to LVEA, VEAX and VEAY.
“Zone Access” does NOT permit access to PSL, OSB Optics Lab, LDR, HPLF Optics Lab, TCS, or TMON or PCAL in VEAX or VEAY.
“Laser Operator” permits access to all NHZ’s.
“Laser Operator” status is necessary but not sufficient to operate any laser at LLO.
