Cerium
According to the Safety Data Sheet (SDS) special precautions must be taken when working with the chemical described above. The following information includes the chemical characteristics of followed by recommendations for handling and any paperwork needed in order to use the chemical in the laboratory. This Standard Operating Procedure will be followed along with the requirements of the Chemical Hygiene Plan.
GHS Classifications: Signal Words: Danger
Pictograms:
Additional Classification: Flammable, General Warning
Brief description of proposed chemical work: The cerium will be placed in a sealed crucible and heated to liquidify alkali metal its with in the crucible. Cerium metal will slowly dissolve into this liquid alkali. The alkali will be allowed to cooled and solidify back to alkali metal. The metal will be neutralized with isopropanol and this solution will be measured using ICP. For more information refer to the Solubility Experiment Procedure.

Section 1: Brief Safety Overview:
● The Principal Investigator is responsible for training employees using the material on site. The training should include a discussion of the known and potential hazards; an explanation of the relevant policies, techniques and procedures including the proper use of personal protective equipment, emergency/spill procedures and containment equipment (engineering controls).
● Limit access to authorized users.
● Minimize the possibility of inadvertent ingestion, inhalation and direct skin or eye contact with the substance.
● Chemical has been entered in the Chemical Inventory (EHS Assistant)
● Require annual training.
Section 2: Research Laboratory Procedures
· Handling Instructions
Example: (Preparation of the stock solutions): Should be handled in inert environment within glovebox and with non-sparking tools. Disposal should be in appropriate EHS containers.
· Storage: The metal will be stored within the glovebox located within W465.
Location – Engineering controls
Ventilation (example: Fume Hood, Canopy Hoods, etc): Glovebox ventilation to building exhaust.
Designated area (specify): Within the glovebox in W465
Bio-Safety Cabinet
PPE required:
Skin/Body Protection (example: Lab Coat) Lab coat
Eye protection
Face shield
Respirator (example: N95): NIOSH approved dust respirator
Hand protection (example: Nitrile gloves): Neoprene Gloves
· Cleanup/Decontamination procedures for work area after use: For spills the material should be swept up. This spill should then be put in an EHS certified disposal container.
· Disposal Procedures Place in proper disposal container. Contact EHS for pickup.
Section 3: Occupational Exposures
· Routes of Exposure
Skin – May Cause irritation
Inhalation – May cause irritation. Large doses can cause loss of muscle coordination.
Ingestion- May cause gastrointestinal irritation.
Injection- N/A
· Toxicological Effects
Acute Effects/ Precautionary Safety Measures: May be hazardous if inhaled, absorbed through skin or ingested.
Chronic Effects/ Precautionary Safety Measures: Readily reacts with moisture to form causitic and highly corrosive sodium hydroxide. These corrosive materials can destroy respiratory tract, eyes, skin, and digestive tract. To avoid effects wear appropriate PPE.
· Occupational Exposure Response and First Aid Measures
Skin: Remove contaminated clothes and brush off solids. Seek medical attention if irritation persists.
Eyes: Immediate flush eyes for 10-15 minutes. Seek medical attention if irritation persists.
Inhalation: Remove victim to fresh air. Seek immediate medical attention.
Ingestion: Give 1-2 glasses of water and induce vomiting. Seek medical attention
· Emergency Procedure for Chemical Spills and Accidental Releases
NEVER USE WATER AROUND CERIUM
If fire occurs Class D fire extinguisher
Steps if a spill of solid cerium:
1. Sweep/Scoop up solid pieces using non-sparking tools and natural bristle brushes.
2. Place spill pieces into a closed container.
3. Then dispose container properly through EHS
This Standard Operating Procedure must be placed in the Chemical Hygiene Plan and the SDS must be accessible. Also, all laboratory personnel must be familiar with safe handling practices (i.e., training with documentation of training) when working with these chemicals. This must be incorporated into the comprehensive chemical hygiene plan of the laboratory. If you have any questions regarding a comprehensive mandatory laboratory chemical hygiene plan please contact your Representative at Environmental Health and Safety (292-1284).For any other questions or concerns, please contact:
