Past project work

Specialized projects we've delivered.

These are examples of fixed-scope engagements we've completed for clients — specialized builds that go beyond our core service lines, from radiation safety programs to specialty gas systems and DEA registrations.

Radiation Safety Program

Full development and implementation of Radiation Safety Programs for X-ray equipment — including state registration, leak surveys, personnel training, and signage.

What we did

  • CDPH Radiologic Health Branch registration for X-ray producing machines
  • Radiation Safety Officer (RSO) designation and written program
  • Radiation leak surveys and shielding evaluations
  • Dosimetry program setup and monitoring
  • Controlled-area signage, postings, and warning systems
  • User training (authorized users, general personnel) with documentation

Lab Setup & Day-One Readiness

Full lab stand-up for day-one operation — PPE, regulatory permits, waste streams, signage, and initial training. From empty walls to ready to bench.

What we did

  • PPE procurement, sizing, and distribution across roles
  • HMBP, EPA ID, and hazardous waste permits filed
  • Waste stream profiling and accumulation area setup
  • Chemical storage setup, labeling, and SDS library
  • Emergency signage, evacuation maps, and spill response kits
  • Day-one onboarding training for all staff before operations begin

SOP & JHA Development

Standard Operating Procedures for lab equipment and process development, plus Job Hazard Analyses for novel or high-risk workflows.

What we did

  • Equipment-specific SOPs (biosafety cabinets, fume hoods, autoclaves, centrifuges, etc.)
  • Process SOPs tailored to your chemistry and workflow
  • Job Hazard Analysis (JHA) for each task with identified controls
  • Pre-task risk reviews and approval pathways for novel work
  • Document control, revision tracking, and training sign-off records

DEA Controlled Substance Program

Development and implementation of DEA controlled substance programs — from initial license application through inventory control and DEA inspections.

What we did

  • DEA registration (Form 225) and state-level controlled substance licensing
  • Secure storage (Schedule II–V) compliant with 21 CFR 1301.75
  • Inventory controls: initial, biennial, and ongoing accountability records
  • Receiving, dispensing, and disposal documentation (DEA Form 41, reverse distributor)
  • Authorized-user rosters and training
  • DEA inspection preparation and on-site support

Specialty Gas Systems

Process gas cabinet setup with manifold delivery — including ventilation, alarms, handling protocols, and regulatory compliance for toxic and pyrophoric gases.

What we did

  • Gas cabinet selection and placement aligned with fire and building code
  • Manifold design, purge assemblies, and cross-purge procedures
  • Toxic gas monitoring and alarm system integration
  • Ventilation and exhaust assessment (per IFC / CFC Chapter 50, 60–67)
  • Written specialty gas handling SOPs and emergency response procedures
  • Operator training and certification program

Exposure Monitoring: Solvent & Metal Dust Assessment

Personal and area air sampling for battery materials R&D labs handling NMP, DMC, EC solvents and Ni/Co/Mn cathode powders — satisfying the exposure determination obligation under 8 CCR §5191(d)(2) before baseline data exists.

What we did

  • Walkthrough survey and Similar Exposure Group (SEG) definition across slurry mixing, coating, calendaring, cell assembly, and glovebox loading
  • Personal full-shift sampling for NMP, DMC, and respirable Ni/Co/Mn metals (NIOSH 7300) across 2 sampling days per SEG
  • Real-time PID screening during high-emission tasks and hood face velocity verification (ASHRAE 110)
  • Lab results compared against Cal/OSHA PEL, ACGIH TLV, and AIHA WEEL with AIHA exposure category (1–4) judgment
  • Written exposure determination memo per §5191(d) — required regulatory record
  • Control recommendations by hierarchy of controls and respirator program triggering analysis (§5144)

Indoor Air Quality / Mold Assessment

Post-leak mold investigation for private R&D and biotech labs — visual survey, moisture mapping, air and surface sampling, remediation scoping, and post-remediation verification per IICRC S520.

What we did

  • Pin/pinless moisture mapping of drywall, ACT, and subfloor; IR thermography of suspect cavities; HVAC supply/return inspection
  • Spore trap air sampling (Air-O-Cell) at 5+ indoor locations with outdoor control, pre- and post-remediation
  • Surface tape lifts and bulk sampling; viable Andersen N6 impaction if speciation is required
  • Remediation scope of work for abatement contractor including containment, negative pressure, and PPE requirements
  • Post-remediation verification (PRV) report and employee-facing communication memo
  • Documentation package supporting employer's reasonable response under 8 CCR §3203 (IIPP)

EtO Off-Gas Exposure Monitoring: Warehouse & Receiving

Exposure assessment for medical device warehouse and shipping/receiving staff handling EtO-sterilized product — the most commonly missed EtO scenario in Cal/OSHA inspections, where downstream handlers are outside the formal sterilization compliance program.

What we did

  • SEG definition for forklift drivers, receiving clerks, QC inspectors, pickers, and RMA staff; aeration and quarantine policy review
  • Full-shift TWA personal sampling (OSHA Method 50) and 15-minute STEL samples during high-emission tasks such as stretch-wrap removal and carton opening
  • Continuous area monitoring (ChemDAQ Steri-Trac or equivalent) at dock, staging, quarantine room, and pick face over full shift
  • Off-gas decay curve for typical incoming load and recommended minimum quarantine hold time before manual handling
  • Written EtO Compliance Program extension to warehouse operations: regulated area designation, medical surveillance enrollment, training, and recordkeeping
  • Periodic monitoring schedule per §5220(d)(4) and BAAQMD Reg 11-17 applicability review for dedicated aeration room exhaust

Exposure Monitoring: Fluorinated Salt Synthesis & HF Hazard Control

Baseline exposure assessment and engineering control verification for glovebox/scrubber synthesis of fluorinated metal salts — including HF upset-condition monitoring, scrubber performance testing, and written program development.

What we did

  • Pre-task JHA verification and personal sampling during representative batches for HF (OSHA ID-110), particulate fluorides (NIOSH 7902), and co-contaminants
  • Real-time HF monitoring with electrochemical sensor at glovebox antechamber and scrubber exhaust throughout full synthesis shift
  • Glovebox integrity verification (pressure decay test) and scrubber performance verification (inlet/outlet sampling, removal efficiency calculation)
  • Emergency response readiness: calcium gluconate gel availability, eyewash flow test, written HF spill and medical response procedure
  • HF-specific written program integrated into the Chemical Hygiene Plan
  • BAAQMD permit applicability documentation and regulatory comparison against 8 CCR §5155 (HF PEL 3 ppm ceiling, STEL 6 ppm)
