Cesium Chloride [CsCl]

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 characteristicsfollowed 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.

The standard operating procedure and high level of care of cesium chloride in an argon atmosphere contained in a glove box, is the same regardless of which species of REM used. A list of physical and chemical information, along with all hazards and safety information, is detailed for following species:

  1. Cesium chloride (CsCl)

This list and the Standard Operating Procedure will be updated annually. Additionally, the MSDS will be provided as an appendix to the Quality Assurance / Chemical Hygiene Plan.

Brief description of proposed chemical work: CsCl is used to study the behavior of fission product effect on rare earth metals in LiCl-KCl salt eutetic. The salt mixture will be mixed and melted in an Argon gas evacuated glove box. All experiments with the molten salt mixture will be performed within the glove box, and CsCl will not be removed from the glove box until is it ready for disposal.

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
  • Cesium chloride will be stored inside glovebox at all times.
  • Containers will never be opened outside of glovebox and Cesium chloride should only be transferred out of container while inside sealed glovebox.

Proper laboratory procedure must be followed and employees must be trained to handle the material.

  • Storage:CsCl will be stored inside glovebox at all times and should only be removed in a sealed container for disposal.

Location – Engineering controls

Ventilation: Glovebox has built-in ventilation system

Designated area (specify): Inside of glovebox at all times, except disposal

Bio-Safety Cabinet

PPE required:

Handling Outside of Glove Box:

Skin/Body Protection:Long sleeves and pants

Eye protection

Face shield

Respirator:

Hand protection: Butyl gloves

Handling Inside Glove Box:

Skin/Body Protection

Eye protection

Hand protection: Butyl Gloves attached to Glovebox

  • Disposal Procedures
  • Used CsCl salt will be disposed in an EHS approved storage container inside the glove box. The container must be sealed prior to removal from the glovebox. Upon request, EHS will pick up the waste container.

Chronic Effects / (see note below) / Carcinogenicity / Carcinogen

*Long term exposure to high dust concentrations may cause changes in lung function (i.e. pneumoconiosis) caused by particles less than 0.5 micron penetrating and remaining in the lung. A prime symptom is breathlessness. Lung shadows show on X-ray. Limited human data are available regarding health effects of caesium. Most studies involve radio-isotopes of caesium such as 137Cs and 134Cs. These radionuclides are products of either neutron activation or nuclear fission and may, therefore, be released from sites where nuclear fission occurs, from radioactive material removed from such sites, or from leakage of radioactive cesium sources. Both 137Cs and 134Cs emit beta radiation (that travels short distances and can penetrate the skin and superficial body tissues) and gamma radiation (that penetrates the entire body).

Exposure Response and First Aid Measures

Skin: /
  • Flush skin and hair with running water (and soap if available).
  • Seek medical attention in event of irritation.

Eyes: /
  • Wash out immediately with fresh running water.
  • Ensure complete irrigation of the eye by keeping eyelids apart and away from eye and moving the eyelids by occasionally lifting the upper and lower lids.
  • Seek medical attention without delay; if pain persists or recurs seek medical attention.
  • Removal of contact lenses after an eye injury should only be undertaken by skilled personnel.

Inhalation: /
  • If dust is inhaled, remove from contaminated area.
  • Encourage patient to blow nose to ensure clear passage of breathing.
  • If irritation or discomfort persists seek medical attention.

Ingestion: /
  • IF SWALLOWED, REFER FOR MEDICAL ATTENTION, WHERE POSSIBLE, WITHOUT DELAY.
  • For advice, contact a Poisons Information Centre or a doctor.
  • Urgent hospital treatment is likely to be needed.
  • In the mean time, qualified first-aid personnel should treat the patient following observation and employing supportive measures as indicated by the patient'scondition.
  • If the services of a medical officer or medical doctor are readily available, the patient should be placed in his/her care and a copy of the SDS should beprovided. Further action will be the responsibility of the medical specialist.
  • If medical attention is not available on the worksite or surroundings send the patient to a hospital together with a copy of the SDS.

Emergency Procedure for Chemical Spills and Accidental Releases

Spills/Leaks:Vacuum or sweep up material and place into a suitable disposal container. Avoid generating dusty conditions. Provide ventilation. Do not let products enter drains.

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:
