Principle
39. Inert Environment
a. Replace the normal environment with an inert one
b. Carry out the process in a vacuum
b. Carry out the process in a vacuum
- Principle Description: Create a neutral (inert) atmosphere or environment in order to support a desired function.
- Hints on Usage: To use this principle, first understand the system’s associated risks — what prevents the realization of a desired function? Decide what must be protected, then create an inert atmosphere or environment for that parameter.
- Consider the types of possible atmospheres or environments: vacuum, gas, liquid or solid. A solid inert atmosphere can include neutral coatings, particles, or parts.
- Do you need an all encompassing or localized environment?
- Do not only consider chemically inert environments. Also consider “environments that do no create harmful interactions”.
- For non-physical systems, how would you make an environment inert to support
a desired function?
