Chemical Safety Data Sheet Lists
- Approved Chemicals Allowed to be used in the KNI with typical SDS (chemical not provided by the KNI)
Requesting New Chemicals
NEVER bring in any chemicals into the KNI Lab before receiving an approval through email that your chemical has been allowed to be used inside the lab.
- Always thoroughly review the SAFETY DATA SHEET of the new chemical being requested BEFORE submitting a request.
- Submit the request through email to the KNI Lab Safety Officer - Bert Mendoza
- Email should include:
- (1) SAFETY DATA SHEET (attached) from manufacture.
- (2) PROCESS DESCRIPTION - a detailed description of the process and how the chemical will be used.
- (3) AMOUNT OR QUANTITY of chemical to be brought into the KNI Lab.
- The KNI Lab provides many chemicals for processing. If the requested chemical will improve your process and can be valuable to other members, include the reasons in the request. Staff may decide it would be beneficial to provide the new chemical for all members and add it to the Chemicals Provided by the KNI with typical SDS list.
- If the chemical is unique to your process, you will be required to supply the chemical and the chemical will be added to the Approved Chemicals with typical SDS list.
