Sodium Hydroxide
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: Corrosive
Brief description of proposed chemical work: Used in the Solubility Experiment, once sodium metal solution has been neutralized with isopropanol sodium hydroxide will be used to precipitate the lanthanide concentration in the solution. 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): Material is stored in original container in specificied cabinet. When using NaOH proper PPE must be worn. Preferred to be handled in proper ventilation.
· Storage: The sodium hydroxide will be stored within the cabinet in the locked W465.
Location – Engineering controls
Ventilation (example: Fume Hood, Canopy Hoods, etc):
Designated area (specify):
Bio-Safety Cabinet
PPE required:
Skin/Body Protection (example: Lab Coat) Lab Coat
Eye protection
Face shield
Respirator (example: N95):
Hand protection (example: Nitrile gloves): Nitrile gloves
· Cleanup/Decontamination procedures for work area after use: For spills the material should be neutralized with vermiculite. This spill should then be put in an EHS certified disposal container.
· Disposal Procedures Once neutralized with vermiculite place the material in an approved container for EHS pickup.
Section 3: Occupational Exposures
· Routes of Exposure
Skin – May cause irritation of eyes and skin.
Inhalation – May cause gastrointestinal discomfort.
Ingestion- May cause burns to respiratory tract.
Injection- N/A
· Toxicological Effects
Acute Effects/ Precautionary Safety Measures: Causes severe burns and harmful if inhaled or swallowed.
Chronic Effects/ Precautionary Safety Measures: Vapor causes irritation to eyes and respiratory passages.
· Occupational Exposure Response and First Aid Measures
Skin: Remove contaminated clothes and brush off solids. Seek immediate medical attention.
Eyes: Immediate flush eyes for 10-15 minutes. Seek immediate medical attention
Inhalation: Remove victim to fresh air. Seek immediate medical attention.
Ingestion: Quickly wipe mouth and do not induce vomiting. Seek immediate medical attention.
· Emergency Procedure for Chemical Spills and Accidental Releases
For spills:
1. Contain Area and Evacuate
2. Vermiculite should be used to completely neutralize spill
3. Sweep/Scoop up (even if on fire) using a shovel
4. Place the material in appropriate container.
5. EHS should then be contacted to bring proper disposal containers.
6. Flush the spilled area
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:
