PROFESSIONAL EXPERIENCE

8/93 - Present    President, Private Company
11/92 - 8/93    Sole Proprietor

Provide Human Factors consulting on product safety.  Human Factors is a multi-disciplinary body of knowledge about human abilities, limitations, and other characteristics relevant to design.  In the context of safety, human factors relates how human characteristics, product characteristics, and the environment can interact to produce hazards.  Services include identifying injury data, technical reports, and safety regulations, and performing the following:

Injury data analysis
- assess hazard probability and severity
- identify hazard patterns

Product design safety evaluation
- determine if hazards can be eliminated via design
- assess whether hazards could be addressed by warnings

Warning label design, test, and evaluation
- determine validity of “failure to warn” claims
- optimize label effectiveness in being seen, read, understood, and followed

Recommendations form the basis for product safety standards, recalls, product design and label specifications, instructions, publications, presentations, and testimony in litigated matters.  Qualified as a Human Factors expert in state and Federal courts across the country.  Expert work is both national and international in scope.  Provide guidance to manufacturers, trade associations, distributors, testing laboratories, and attorneys.  Have 3-1/2 decades of experience in:

- Children’s hazards and child development
- Workings of US Consumer Product Safety Commission
- Appreciation of risk (manufacturer vs. users)
- Workings of standards groups ASTM, ANSI, ISO

BACKGROUND

9/79-10/92    Engineering Psychologist, Human Factors Division
U.S. Consumer Product Safety Commission

For 13 years, performed Human Factors assessments of consumer products to determine if a hazard exists that warrants action, and to determine how to reduce injuries.  Analyzed accident data to identify hazard patterns, evaluated product designs and safety labels and instructions, developed and adapted technical literature, and recommended product redesigns and warnings.  Presented findings to CPSC Commissioners, manufacturers, trade associations, and standards-writing groups.  Findings formed the basis for recalls, bans, mandatory and voluntary safety standards, public information, and no action determinations.  Authored reports on diverse product hazards.  Received 10 awards for Human Factors technical assessments.

1976        Bachelor of Arts, Psychology and Sociology

HUMAN  FACTORS ANALYSES - PRODUCT HAZARDS

Analyses are of three types:

-  “Case” - refers to either expert witness or consulting expert work on specific cases.

-  “CPSC” - refers to an analysis performed while at CPSC, usually including analyzing injury data on multiple incidents to identify hazard patterns, evaluating product designs and safety labels, evaluating safety standards, and recommending ways to reduce hazards.

-  “Manufacturer” - refers to guidance provided to manufacturers.
