|About this Process|
Write a brief description of what this process is used for here.
Equipment needed need for process
- List all of the equipment you need to run this process. This includes everything from tweezers and beakers to furnaces and plasma etchers. Be complete. If this is a new process that has not been done in the LNF before, consult with LNF staff to make sure that equipment you need is available and that there is no cross contamination issues. Be sure to make these linked in the wiki and vice versa.
Chemicals needed for process
- Include a complete list of the chemicals needed. If specific concentrations, purities, or grades are necessary cite them here. Also include the CAS Number for each chemical, if there is more than one. If there is no CAS Number, specify that one is not given. If the chemical is a “Pre-mixed” solution (pour straight from the bottle and do not mix with any other chemical) do not include the trace components CAS number. If the solution is a “NON-Pre-mixed” then include the CAS number for all compatible chemicals to be mixed together.
- links to the Safety Data Sheets (SDSes)
Protective equipment needed
- What do you wear to protect yourself while performing the process? Check SDS, but be aware that the protective equipment standards cited in these documents frequently refer to handling the chemical outside of approved engineering controls. If you do not know what protective equipment to use or what types of gloves are compatible with the chemicals you will be using, consult LNF or OSEH staff. Use PPE that is specific to the LNF. That is, Trionic gloves, nitrile gloves etc.
- links to bench procedures
- Where will you store this in the LNF (e.g., solvent, acid, or base cabinet, refrigerator, etc.)? Be aware of incompatibility with other chemicals already in use in the lab. For example, one chemical might react violently with another. In this case you would want to avoid storage in a cabinet with this second chemical. Information will found in the SDS. Storage for the chemical must be identified before chemical can be approved.
- How do you dispose of the waste products used in making the material, after using the material or after the material is depleted or gets old? Be specific and describe the specific disposal procedure to be used within the LNF. Wastewater from the SSEL goes to a neutralization system, so acids and bases can typically be aspirated or dumped down acid drains. Some solvent wastes can be disposed of by aspirating it in a solvent bench. Other chemical wastes must be collected in bottles and properly labeled for disposal by OSEH. Ask LNF staff for assistance if you do not know how the waste chemical should be handled. Treatment of waste must be addressed before a chemical can be approved.
