TerraGraphics’ staff provides on-site evaluations of safety and health hazards and assists in the elimination of those hazards. In addition, TerraGraphics provides experienced professionals in key staff augmentation positions for our clients. Our safety professionals are subject matter experts for job and task analyses and planning. We help our customers ensure compliance with requirements in construction and general industry. TerraGraphics is dedicated to providing the highest level of professional services using Nationally Accredited Laboratories and Board Certified Professionals.




TerraGraphics supports Safety and Health Organizations with development of internal and external assessments following prescribed procedures. This support helps facilitate safety and industrial hygiene awareness campaigns, schedule events and activities, and assist with completion of programmatic requirements that are necessary for successful operations. The scope of this work provides administrative functions and program support services where the products generated are subject to the controls and review/approval processes. Compliance with federal, state, and local requirements for industrial hygiene/safety programs plays a key role. Some IH elements that the TerraGraphics staff have experience with include:

  • Beryllium hazard characterization
  • Chemical, Biological, and Physical Hazard Identification and Control
  • Industrial Safety Technical Support
  • Procedure Management Support
  • Safety and Health Performance Assessments
  • Industrial Safety Training
  • Exposure Data Management
  • Regulatory Compliance
  • Facility Safety
  • Electrical Safety
  • Confined Space
  • Accident Investigation
  • Crane and Rigging
  • Trenching & Shoring
  • Job Hazard Analysis

In addition, TerraGraphics has been responsible for updating industrial hygiene documents, including manuals and procedures to ensure compliance with applicable regulations and requirements.


TerraGraphics staff provides quality assurance (QA) support to government and industrial clients utilizing Certified Quality Engineers and Ph.D. level professionals with decades of QA experience. Our staff has experience building and implementing corporate and laboratory Quality Management Systems, QA plans and procedures for compliance to a number of regulatory requirements or guidelines including ISO 9001, ASME NQA-1, ISO 17025, NELAC, AIHA-LAP. Our staff can assist with internal auditing, procedural documentation, and report writing. Quality Assurance Technical Consulting Services may be as comprehensive as building an entire QA system from scratch, or as limited as single requirement auditing services or procedure development. TerraGraphics will tailor our services to meet the client needs.




TerraGraphics provides analytical chemistry/radiochemistry professional support. TerraGraphics professionals have a combined 50+ years of laboratory management in all aspects of laboratory operations. This experience includes everything from high throughput government-owned chemistry and radiochemistry laboratories, to small industrial hygiene laboratories, to high throughput private environmental laboratories. If you have needs in the area of analytical chemistry or interpretation of laboratory results, TerraGraphics can help.


TerraGraphics plays a key role in a project demonstrating the feasibility of using a Mobile Atmospheric Monitoring Laboratory to quantify volatile air contaminants in real time with part per trillion to part per billion detection levels. These results are used in worker Health and Safety investigations. The mobile laboratory contains a Proton Transfer Reaction – Mass Spectrometer (PTR-MS) instrument using Time of Flight (TOF) technology. This work is being done in support of ongoing quantitative measurements of vapor emissions. The project goal is to implement selected vapor monitoring technologies that can be deployed to support plant operations related to real-time short duration vapor release events. TerraGraphics provides Project Management, subject matter expertise utilizing multiple Ph.D. Chemists, project Quality Assurance, and data processing, reduction, and reporting.

As part of the Mobile Lab project, TerraGraphics has assembled a world class team of experts to process, manipulate, deconvolute, and report PTR-MS data. This allows for the rapid reporting of hundreds of chemical compounds with exceptional time resolution at part per trillion levels. Further mathematical workup of this data gives Health and Safety professionals statistical analysis of vapor concentrations, including max/min, means, concentration distributions, and comparison to Occupational Exposure Limits. Advanced data visualization tools are used to plot results in an easily useable form for clients. Using advanced analytical and computing algorithms, data is expressed with spatial and temporal resolution for a variety of chemical constituents at trace levels.
