In your experiment proposal, you must indicate whether you will be working with chemicals at the ALS. In the Experiment Safety Assessment Form (ESAF), identify each chemical that you will be working with and let the ALS Chemical Safety Specialist know if any are flammable, toxic, engineered nanomaterials or reactive items. LBNL has an on-line MSDS database that can provide information for most chemicals. In addition, indicate if there will be any exceptional hazards (explosives, very large volumes, etc.).
To ship samples to the ALS, send them in care of the beamline scientist using the following address:
[Insert Beamline Scientists Name]
Advanced Light Source
One Cyclotron Road
Berkeley, CA 94720
All materials need to be shipped in accordance with all DOT/IATA (Department of Transportation and International Air Transport Association) regulations.
Chemicals that come from original source vendors such as Sigma-Aldrich, Alfa need prior approval from the ALS Chemical Safety Specialist prior to ordering the chemical. This includes the drop-shipment of compressed gas cylinders.
All chemicals used in specific experiments need to be listed on the Experimental Safety Sheet (ESS) with the form of the chemical and the amount to be used. The ESS will be reviewed and specific controls will be added as the permitted use of each chemical.
Chemical use on the experimental floor is normally restricted to:
- Simple operations (such as loading samples into chambers)
- Modest quantities (typically 1 gram or less)
- Relatively non-hazardous materials (NFPA hazards of 2 or less)
Typical controls will be applied to the use of these chemicals include:
- Personal Protective Equipment (PPE) including safety glasses and gloves
- Hazard communication (SDS, labeling)
These will be listed at the bottom of the chemical safety page of the ESS. If you will be using hazardous material, the use may be restricted to designated area such as a beamline work bench. Your beamline scientist will show you these locations and the PPE requirements for working there.
ALS Chemistry Lab
Complex work or work with more hazardous or larger quantities of chemicals will need to be performed in one of the two User Chemical Labs. The Chem Labs are equipped with fume hoods, sonicators, and basic lab supplies. In order to gain access to the Chem Labs you must take the on-line course EHS 0348 Chemical Hygiene and Safety then have a lab orientation from the Chemical Safety Specialist. You will be required to fill out a form explaining the work that needs to be performed in the lab. Contact the ALS Chemical Safety Specialist for more information.
The ALS Chem Lab supplies basic solvents and gases for use by experimenters. These include: acetone, ethanol, and isopropanol. In addition to the normal gases used at the beamlines (Nitrogen, Argon, Helium, Oxygen and Hydrogen), the ALS supplies ammonia, carbon monoxide, sulfur dioxide, nitric oxide, and nitrogen dioxide. See the chemical page for specific purities of each material.
Health Hazard Gases
Only certain beamline are equipped to use health hazard gases. Please contact your beamline scientist for more information regarding.
The ALS will supply following health hazard gases:
- Carbon monoxide (99.99%) Lecture bottle and A3 cylinders
- Ammonia (99.99%) Lecture bottle
- Sulfur dioxide (99.9%) Lecture bottle
- Nitric oxide (99.5%) Lecture bottle and 9 cu ft cylinder
- Nitrogen dioxide
Contact the ALS Chemical Safety Specialist for gas use and set-up.
All unused chemicals should be sent back to your home institute. The Chemical Safety Specialist can assist in preparing the shipment of your chemicals. All standard rules apply for shipping of hazardous materials. If you plan to dispose of hazardous materials, you must inform the Chemical Safety Specialist at your earliest possible convenience.
All samples and chemicals should be sent back to your home institute after your experiment. If you need to store samples and chemicals at the ALS, you must contact your beamline scientist to request that they take responsibility for your samples. These samples and chemicals need to be clearly labeled with the name of the ALS responsible person, the name of the actual owner and institute, the constituents of the sample, date, and the hazards of the sample. This option is only for users that have proposals in the system and have scheduled to do additional experiments at the ALS. If you cannot meet these requirements, you cannot store samples or chemicals at the ALS.
Before beginning work with hazardous materials, you should familiarize yourself with the LBNL Emergency Response Guides. Location-specific copies are posted on bulletin boards around the ALS floor.
If a chemical spill results in an emergency, call the Lab’s emergency number directly (ext. 7911). All chemical spills should be reported to the Control Room (ext. 4969). Until help arrives, follow the SWIMS guidelines:
Isolate the area
Stay until help arrives
