limination or substitution of
hazardous materials during the products' life cycle is described, together
with steps in partnering and jointly working pollution prevention (P2)
The Pollution Prevention Program (PPP) Plan defines the Bell-Boeing V-22 Engineering Manufacturing Development (EMD) PPP. Specifically prohibited was the use of asbestos, ozone depleting substances, and surface coatings containing lead. Volatile organic compounds content in primers and topcoats may not exceed regulatory requirements.
- Identifying a hazardous materials listing was crucial and time-consuming. Families of chemicals were selected to avoid a long list. The plan addresses responsibilities of all functional groups in relation to P2 and implementation. Coordination and communication between functional groups, Boeing, and the customer are essential.
- Included was training of design engineers and all those involved in carrying out the plan.
- The logistics role is critical to the success of the P2 effort, especially as far as the customer is concerned.
When selecting materials and processes, contract language requires the environmental impacts to be minimized during the life cycle (system definition, design, engineering development, manufacture, operation, maintenance and repair) of the weapon system. The environmental impact is considered equally with other design criterion.
Ultimately, the hazardous materials are identified, prioritized, and trade studies recommended. This plan requires justification of use of specific hazardous materials if they cannot be eliminated. A database conveying this information is given to the customer. Hazardous materials are prioritized based on five factors weighed equally: (a) amount of material used on V-22; (b) toxicity of material to human health; (c) the environment; (d) disposal, handling, and storage method associated with waste products; and (e) legislation associated with use and disposal of the material.
Bell Helicopter used P2 framework previously established through prior manufacturing programs to achieve the V-22 P2 requirements.
Bell Helicopter has pursued and accomplished an effective measurement of P2 efforts. The measurement system must be credible, verifiable, and normalized. Bell is currently implementing a computerized Material Safety Data Sheet (MSDS) and chemical inventory database to allow more accessible information for P2 activities. Environmental considerations during life cycle and documentation of successes or difficulties is important to success.
