    Facilities which utilize hazardous liquids and gases represent a significant potential liability to the owner, operator, and general public in terms of personnel safety and preservation of assets. It is obvious that a catastrophic incident or loss of property or personnel is to be avoided at all costs. This book was conceived to give the reader a guide to understanding the requirements of the various codes and regulations that apply to the design, construction, and operation of facilities utilizing hazardous materials in their processes.

    Background: Do you have a forged or altered document? I can promptly and accurately solve your problem. My years of experience can solve cases of forgery, altered numbers, record alteration, graffiti, anonymous writings and poison pen letters. As a Certified Document Examiner I examine and identify signatures, hand printing, handwriting, initials, and numbers. I also study documents made by computer printers, typewriters, and markings on walls, glass, wood or even automobiles. I compare papers, inks, printing, typewriting, computer-generated documents, facsimiles, photocopies, rubber stamps and holes made by a stapler or hole punch.

    I am a forensic document examiner and a certified forensic physician—uniquely combining two scientific disciplines that each help people in need. My special interest is altered medical records, but I examine all types of documents for authentication or alteration. I have ongoing research studies correlating peculiarities in handwriting and health issues. I am the only private document examiner in West Central Texas, but I am available for cases anywhere in the world. If you are a law firm, I'll be glad to fax you a copy of my Curriculum Vitae so you can have it on file next time a forgery case comes across your desk.
