Chemical Policy
|
Chemicals, biological and soil samples are strictly controlled.
Contact the ALS users office for procedures for the permission, receipt, management, retention, and disposal of chemical, biological, and soil samples.
Users who bring or have chemicals shipped for their use at the ALS are required to characterize, label, and tag them for health and safety removal before their departure at the end of each experiment.
No user chemicals can be stored.
Shipment of chemicals off the site is complicated and cannot be done without approved transportation-licensed carriers.
Users are required to clean and service all contaminated chemical lines, valves, pumps, and vacuum parts and restore them to working order for other users. In general the beamline funding will provide for normal purchases for upkeep of equipment and supplies. However, damage to equipment that occurs through unusual negligence will be replaced at the user's expense.
The ALS Chemistry Laboratories for users are located in Building 6, Rooms 2233 and 2245. Prior to use, all users wishing to prepare samples, clean surfaces, etc., must apply for access. Please go here for more information. Note: Allow for a minimum of 24 hours for approval.
