Section 184.108.40.206 of Pub 3000, Laser Chapter states “At LBNL, the LSO shall develop and issue laser protocols, which are interpretations of ANSI Z136.1 requirements that provide acceptable solutions for frequently encountered experimental situations, or resolve conflicts between standards, where the primary Z136.1 recommended control measures are not feasible or practical. Such protocols will be reviewed and approved by the LBNL Laser Safety Committee to ensure they provide equivalent protection, and fit into LBNL’s research environment and needs.”
Below are links to individual Laser Protocols.
Protocol: Emergency Stop
For emergency conditions, a clearly marked “Emergency Stop” button or other appropriately marked device suitable for the intended purpose of deactivating the laser is required for Class 4 and is recommended for Class 3B lasers. In some cases, the indication of the location of electrical circuit breakers or laser cutoff switches will be sufficient to act as a replacement for this device. An evaluation by the LSO may determine that the panic button is not required.

Implementation Guide for Control of Hazardous Laser Energy
The document provides guidance to all LBNL laser users for the implementation of controls for hazardous energy (CoHE) during laser service and maintenance, where the employee may be exposed to the unexpected energization, startup, or release of hazardous laser energy.
