Core Responsibilities

Primary Functions

Develop and maintain a comprehensive xenon safety program, including written standard operating procedures (SOPs), safe work permits, and engineering controls tailored to both gaseous and cryogenic (liquid) xenon use to prevent asphyxiation, over-pressurization, cold burns, and other hazards.
Perform detailed risk assessments and job hazard analyses (JHAs) for systems and processes that involve xenon (cylinders, gas panels, cryostats, high-pressure vessels), and recommend and verify corrective actions to reduce risk to ALARP (As Low As Reasonably Practicable).
Design, specify, and verify ventilation, gas detection, and alarm systems (fixed and portable) to ensure continuous monitoring for oxygen displacement and xenon leaks; work with engineering and facilities teams to validate sensor placement, setpoints, and response logic.
Lead incident investigation and root-cause analysis for any xenon-related events, near-misses, or equipment failures; prepare formal incident reports and coordinate corrective and preventive action plans with technical teams.
Manage high-value xenon inventory and custody chain-of-control processes, including cylinder tracking, serial-controlled inventory systems, loss prevention strategies, and reconciliation of deliveries and returns to minimize financial and operational risk.
Oversee hazardous materials transportation compliance for xenon shipments (DOT, IATA, ICAO, IMDG as applicable), including classification, packaging, labeling, documentation, and vendor qualification for carriers and freight forwarders.
Maintain regulatory compliance with applicable standards and codes (OSHA 29 CFR 1910 general industry, NFPA 55: Compressed Gases and Cryogenic Fluids, ISO 45001, local environmental reporting requirements), and prepare for and respond to internal and external audits and inspections.
Establish and deliver training curricula for employees, contractors, and vendors on xenon hazards, safe handling of compressed gas cylinders and cryogenic liquids, emergency response, permit-to-work systems, and PPE selection and use; document training records and competency assessments.
Develop and manage emergency response plans specific to xenon releases and cryogen incidents, including coordination with on-site fire brigades, local emergency services, and law enforcement when necessary; lead periodic drills and post-drill evaluations.
Approve and control procurement specifications and vendor contracts for xenon supply, manifolds, cylinder storage systems, pressure regulators, valves, and cryogenic equipment to ensure safety- and compliance-focused sourcing decisions.
Implement and enforce safe cylinder storage, segregation, and securing practices; design and maintain secure storage areas with secondary containment, signage, grounding/earth bonding where required, and theft-prevention measures.
Provide technical review and approval for piping and instrumentation diagrams (P&IDs), pressure relief sizing, pressure vessel data, and gas distribution systems that handle xenon; collaborate with process and mechanical engineers to incorporate inherently safer design where possible.
Oversee calibration and maintenance programs for pressure relief devices, regulators, flow meters, gas detectors, and cryogenic controls; maintain calibration records and service histories to meet audit and safety requirements.
Lead the development and execution of permit-to-work and confined space entry procedures for tasks involving xenon-containing systems, ensuring gas testing, isolation, and rescue plans are in place and followed.
Coordinate cross-functional risk reviews for new xenon-related capital projects, R&D experiments, or process changes, providing EHS input during design, commissioning, and startup to minimize latent hazards.
Evaluate and approve personal protective equipment (PPE) ensembles and rescue equipment required for xenon operations, including cold-handling gloves, face/eye protection, oxygen monitoring PPE, and SCBA/escape respirators where oxygen-deficient atmospheres are possible.
Maintain environmental controls and reporting for xenon use and potential releases, including air emission considerations, waste gas capture, and leak minimization strategies to reduce venting and environmental impact.
Monitor industry developments, safety standards, and best practices for noble gases and cryogenics; apply continuous improvement techniques to update the xenon safety program and to reduce operational costs and risk.
Work with procurement and finance to develop policies for secure handling of high-value xenon, including insurance coordination, loss/theft investigations, and reconciliation procedures to protect organizational assets.

Secondary Functions

Provide subject-matter expertise to R&D and production teams during experimental design or process scaling that involve xenon, offering practical safety and regulatory guidance to enable scientific goals while maintaining compliance.
Serve as primary EHS liaison to external stakeholders (xenon suppliers, shipping carriers, regulatory agencies, insurance underwriters) to resolve compliance questions and to pre-qualify vendors on safety performance.
Maintain and update detailed xenon inventory and usage reports to support budgeting, procurement forecasting, and regulatory reporting obligations.
Support procurement and engineering with technical specifications and acceptance testing criteria for xenon cylinders, manifolds, regulators, and cryogenic equipment to ensure compliance with safety and performance requirements.
Coordinate vendor and contractor safety pre-qualification and on-site orientation specific to xenon handling and high-pressure gas systems; review contractor workplans for safe work practices and permits.
Participate in cross-disciplinary safety committees, ISO or management system activities, and continuous improvement initiatives that touch xenon operations, such as cost-to-emission reduction programs and asset security improvements.
Develop and maintain emergency equipment caches and response kits (oxygen monitors, portable gas scrubbers, spill/evaporation mitigation tools) tailored to potential xenon incidents and train designated responders in their use.
Contribute to technical documentation, risk registers, and permit renewals; maintain records to support audits, incident inquiries, and internal management reviews.
