Job Summary

Provide technical leadership for process safety, chemical risk management, and engineered safeguards across a vertically integrated acrylic and glass transparency manufacturing facility supporting civil and military aerospace programs.

Prevent fires, explosions, toxic releases, uncontrolled polymerization, chemical exposure events, environmental releases, and production interruptions by applying disciplined chemical engineering, process hazard analysis, mechanical integrity, management of change, operating procedure, and emergency preparedness practices.

Translate Cal/OSHA PSM, federal OSHA PSM, EPA RMP, California CalARP, Orange County CUPA, fire code, hazardous materials, and aerospace customer expectations into practical risk controls for MMA/monomers, flammable solvents, adhesives, coatings, resins, catalysts/inhibitors, tanks, reactors/mixers, ovens, autoclaves, furnaces, utilities, and chemical storage/transfer systems.

Job Responsibilities

1. Process Safety Program Leadership

Develop, maintain, and improve the site process safety and chemical risk management framework, including process safety information, hazard review/PHA, MOC, pre-startup safety review, mechanical integrity, operating procedures, training, emergency planning, and incident investigation.
Determine applicability and maintain evidence for Cal/OSHA PSM, federal OSHA PSM, EPA RMP, and California CalARP requirements based on regulated substances, flammable quantities, process configuration, and threshold calculations.
Lead process safety governance for high-hazard areas such as MMA/monomer storage, resin/casting operations, solvent bonding, coating/primer application, mixing, curing, ovens, autoclaves, furnaces, tanks, utilities, and chemical transfer systems.
Advise EH&S and site leadership on risk acceptance, escalation, capital needs, production changes, temporary operations, and stop-work decisions involving chemical or process safety risk.

2. Process Hazard Analysis and Risk Assessment

Lead or facilitate PHAs, What-If/Checklist reviews, HAZOPs, LOPA-style assessments, FMEAs, facility siting reviews, dust hazard screening, thermal hazard reviews, and task-based chemical risk assessments as appropriate.
Maintain risk registers, recommendation logs, safeguard verification records, action owners, due dates, and effectiveness checks.
Evaluate credible scenarios including MMA overheating or polymerization, loss of inhibition/cooling, flammable vapor release, static ignition, solvent fire, tank overpressure, dust collector fire, oven/autoclave upset, coating booth fire, utility loss, incompatible chemical mixing, and emergency shutdown failure.
Ensure risk reviews include operators, maintenance, engineering, EH&S, quality, and area leadership to capture practical operating knowledge.

3. Chemical Engineering and Safeguard Design

Define engineering controls for tanks, mixers, transfer systems, vents, relief devices, alarms, interlocks, emergency shutdowns, ventilation, grounding/bonding, secondary containment, temperature control, cooling/refrigeration, inhibitor management, and vapor control.
Support design and troubleshooting of chemical storage, transfer, reaction/curing, coating, cleaning, filtration, dust collection, wastewater/waste interfaces, and emissions-control systems.
Apply recognized and generally accepted good engineering practices (RAGAGEP), vendor requirements, insurer guidance, NFPA concepts, fire code expectations, and site standards to chemical/process equipment.
Partner with engineering and maintenance to ensure critical safeguards are captured in preventive maintenance, inspection, calibration, testing, spare parts, and failure-response procedures.

4. Management of Change and Pre-Startup Safety Review

Review changes to chemicals, formulations, suppliers, SDS data, process parameters, batch sizes, tanks, equipment, controls, utilities, ventilation, relief systems, layouts, software/PLC logic, operating procedures, staffing, and production rates.
Ensure MOC reviews address EH&S, air/water/waste permits, fire code, CUPA/CERS, CalARP/RMP/PSM applicability, product quality, aerospace customer approvals, and emergency response impacts.
Lead pre-startup safety reviews for new or modified processes to verify engineering completion, procedure issuance, training, PHA action closure, permits, inspections, labeling, emergency equipment, and maintenance readiness.
Manage temporary change controls and ensure temporary deviations have risk assessment, duration limits, monitoring, authorization, and closure.

5. Chemical Inventory, Thresholds, and Regulatory Interface

Maintain chemical/process threshold analyses for PSM, RMP, CalARP, CUPA/HMBP, fire code, hazardous materials storage, and emergency planning applicability.
Review SDSs and chemical hazard data for flammability, reactivity, thermal stability, inhibitor requirements, peroxide-forming potential, polymerization risk, incompatibilities, toxicology, VOC/HAP/TAC content, and storage requirements.
Support CERS/Hazardous Materials Business Plan accuracy, CalARP/RMP submissions if applicable, regulator inspections, information requests, and coordination with Orange County Health Care Agency CUPA and Orange County Fire Authority.
Coordinate with environmental air, water, and waste leads when chemical/process changes affect SCAQMD permits, stormwater/wastewater controls, hazardous waste profiles, or spill prevention.

6. Operating Procedures, Training, and Field Verification

Develop or technically review operating procedures for chemical transfer, tank unloading, mixing, storage, heating/cooling, bonding, coating, cleaning, startup, shutdown, emergency shutdown, abnormal conditions, and temporary operations.
Train operators, maintenance, engineers, supervisors, and emergency responders on process hazards, safeguards, operating limits, alarms, emergency actions, chemical incompatibilities, and escalation expectations.
Perform field verifications of procedure use, critical alarms/interlocks, relief devices, ventilation, grounding/bonding, container closure, inhibitor/cooling checks, hot work controls, and chemical transfer practices.
Ensure procedures and training support multilingual workforces and practical shop-floor execution.

7. Incident Investigation and Emergency Preparedness

Lead or support investigations of chemical releases, fires, near misses, overheating events, alarm bypasses, loss of containment, off-spec mixing, abnormal reactions, control-device failures, spills, exposure concerns, and emergency response activations.
Apply rigorous technical root-cause methods and ensure corrective actions address engineered safeguards, operating limits, maintenance systems, procedures, training, supervision, and verification of effectiveness.
Develop credible emergency scenarios for drills and tabletop exercises involving MMA, solvents, coatings, fires, earthquake impacts, power loss, tank failures, ventilation loss, and chemical release response.
Coordinate with EH&S leadership, security, operations, OCFA, CUPA, and emergency response contractors on preplans, response resources, and recovery expectations.

8. Aerospace & Defense Mission Assurance Linkage

Ensure process safety controls protect uninterrupted civil and military aircraft transparency production, customer commitments, and defense supply continuity.
