Hazards Analysis cont’d
The purpose of this HAR is to identify hazards
associated with the design and operation of the
LUSI project; assess risk; and establish controls
Hazards capable of causing injury to personnel, harm to
the environment, or damage to critical hardware have been
considered in the analysis
This HAR documents the safety analysis of the LUSI
instrument design/build/install & test
A separate Operating and Support Hazard Analysis
(O&SHA) will be developed for LCLS experiments. The
O&SHA will evaluate activities for hazards introduced into
the system by operational and support procedures

Hazards Analysis 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.
LUSI 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 associated with ionizing radiation.
The LUSI instruments are designed to 10CFR 835
defines radiation protection regulations for the protection of
individuals from ionizing radiation
LUSI will design, build, install and test instruments
within parameters of LCLS SAD
The instruments will comply with the approved Accelerator
Safety Envelope (ASE)

Overview of Hazards
The results of the Hazards Analysis Report were consistent with
those of the LCLS analysis that resulted in a low hazard facility
determination following the criteria defined in DOE-O 420.2B,
Safety of Accelerator Facilities, based on the following:
LCLS requirements for SLAC Linac operations are well within existing
safety and operating envelopes of the facility.
The average power of the LCLS x-ray beam, the energy and power of the
electron beam, and hence the radiation hazard they pose are all well within
the range of applicability for SLAC shielding and safety systems
The risk (probability & consequences) of all hazards will be similar in
nature and magnitude to those already found in the present
accelerator storage ring experimental programs
Existing and mature programs (citizen safety committees, ES&H
division, Work Authorization) will be engaged to ensure that all
aspects of the design, installation, and testing phases of LUSI will be
properly managed

Hazard Assessment Process
The hazard assessment process is a
principal factor in the
understanding and management of
technical risk. System Safety is an
integral part of the overall program
risk management decision process
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 MILSTD-882D, Standard Practices for
System Safety.
Defense Standards are also used by
other non-Defense government
organizations, technical
organizations, and industry

Occupational Safety Requirements
The LUSI equipment shall be designed and constructed in
such a manner to protect the safety of workers, the
public and the environment following 29CFR1910. The
safety philosophy and practice to be followed on the LUSI
project will include the following elements:
DOE P 450.4 Safety Management System Policy
Adherence to SLAC Work Smart Standards
10CFR835 Occupational Radiation Protection / ALARA
Controlling hazards by eliminating them whenever possible
Implementing safety programs to ensure worker safety during
construction and testing
Performing independent design reviews

Installation Phase Hazards
Radiation – there is no source of radiation during the fabrication and
installation phases of the project
Fire Protection - LUSI is protected by a conventional fire sprinkler system and a
Very Early Smoke Detection Apparatus (VESDA) system.
Electrical – hazards will be controlled by adhering to NFPA 70E standards
Thermal/Cryogenic – Handling of cryogens shall be compliant with SLAC ES&H
Manual Chapter 36, Cryogenic Oxygen Deficiency Hazard Safety
Oxygen Deficiency – hazard potential is minimal due the small quantities of
gases in liquid state that will be used within the facility
The requirement for air monitoring will be included in the evaluation of the hutches.
Vacuum / Pressure - LUSI consists of numerous vacuum components and the
vacuum chambers will have burst disk that are compliant with 10CFR851.
Pressure relief valves are integral to the vacuum system to prevent them from being
over-pressurized while venting.
Others = Chemical, Environmental Insults, Magnetic, Mechanical, Seismic
Identified and addressed
