ISEMS Process cont’d

The Environmental Assessment developed for the LCLS resulted in a Finding of No Significant Impact encompassed the physical space occupied by LUSI and its operations

The LUSI Hazard Analysis Report states its instruments are being designed so that they will not pose hazards to people or the environment

The most significant potential hazard associated with LUSI instruments is that related to ionizing radiation

The LUSI instruments are designed to 10CFR 835 defines radiation protection regulations for the protection of individuals from ionizing radiation

LUSI instruments will be designed and built w/i the scope of LCLS SAD

The instruments will comply with the approved Accelerator Safety Envelope

Hazard Assessment Process

The hazard assessment process is a principal factor in the understanding and management of technical risk. Hazard severity is an assessment of the worst potential consequence, defined by degree of injury or property damage, which could occur Probability is the likelihood that an identified hazard will result in a mishap, based on an assessment of such factors as location, exposure in terms of cycles or hours of operation, and affected population.

These levels are derived from MIL-STD-882D, Standard Practices for System Safety.

Defense Standards are also used by other non-Defense government organizations, technical organizations, and industry
