9Life Cycle Assessment The StagesFor the sake of
simplicity the life cycle is divided into unit
processes usually broken down as follows
pre-manufacture, manufacture, distribution and
installation, use and service, and end of life
management. Each unit process is then evaluated
in three areas safety, conservation, and
pollution. The inputs and outputs of each life
stage are the criteria for evaluation.

19- What is a Life Cycle Assessment?
- Qualitative process used to assess EHS
- impacts of product during its lifecycle
- What does it provide?
- Relative magnitude of EHS impacts
- Areas of information gaps
- Priorities for green design
- Priorities for green technology development
- And.
- Raises consciousness of organization
20Materials/ Processes of Concern

- Materials Of Concern
- Hazardous Materials Index
- Product Comparisons
- Standard Work
- Green Technology Goals
- Summary
22Materials Of Concern
- Objectives
- Identify hazardous material risks across the
enterprise - Provide a deliverable for incorporation into
standard work - Create a green index to drive green technology
plan - Rationale
- Appearance of targeted materials on one or more
industry, customer or regulatory list(s) of
hazardous materials - Relevance to Pratt Whitney product lines or
processes - Potential linkage to product and process design
callouts
23Definition Of Categories
- Prohibited
- high risk materials not permitted in new design
and development - Restricted
- high risk materials that can only be used with
appropriate levels of approval - plan must be established to validate alternate
green material - To Be Reduced
- materials known to have detrimental
environmental, health and safety impacts.

25Hazardous Materials Index
- Purpose
- provide metric to define greenness of products
- link materials to specifications/design callouts
- Assign toxicity values to materials process
specifications based on Purdue University
rankings - Quantify green indices based on Pratt Whitney
Canada algorithm - Ih TnP/N
- where Ih Hazardous Material Index
- T toxicity value of specification
- nP number of part numbers that call out
specification - N total number of part numbers in engine
26Hazardous Materials Index
- Implementation
- Establish metrics/set goals
- Establish signoff/approval protocols
- Control via standard work
27Technology Opportunity
28Standard WorkMaterials Of Concern
- Contains background, contacts and protocols
- References material and process specification
list - Links to data base containing materials of
concern, toxicity rating detail, identified by
specifications - Links to menu for selection of alternate
materials and processes, cross-referenced by
specification
29Materials of Concern List with Specification
Number
30Green Technology Goals
- Goals established based on driving down product
hazardous materials index - Goal for legacy products will be based on
designing out prohibited materials - Goal for new designs will be based on eliminating
the use of restricted materials
31Summary
- Comprehensive effort to identify hazardous
material risks across the Pratt Whitney
enterprise - Risks defined by levels of concern
- Standard work tool for designers established
- Goals in process of being defined
- Hazardous Materials Index will drive technology

will be about increasing returns where we learn
to exploit virtuous cycles rather than manage
vicious ones.
