Neodymium (III) Chloride [NdCl3]

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 and attention for rare earth metal (REM) chlorides in an argon atmosphere contained in a glove box, is the same regardless of which species of REM used. This standard operating procedures details information about multiple species of REM. A list of physical and chemical information, along with all hazards and safety information, is detailed for following species:

  1. Neodymium (III) Chloride (NdCl3)

This list and the Standard Operating Procedure will be updated annually, or whenever a new species of REM chloride will be used in an experiment. Additionally, the MSDS for each REM chloride will be provided as an appendix to the Quality Assurance / Chemical Hygiene Plan.

Brief description of proposed chemical work: NdCl3 is one of the Rare Earth Metal (REM) chlorides that is used to study the behavior of rare earth metals in this salt mixture. 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 NdCl3 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
  • Neodymium chloride will be stored inside glovebox at all times.
  • Containers will never be opened outside of glovebox and Neodymium 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:NdCl3 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

Occupational Exposures

Routes of Exposure
Skin: / Moderate skin irritation.

Inhalation: / Produces irritation of the respiratory system
Ingestion: / Immediate defecation, writhing, ataxia (the inability to coordinate voluntary muscular movement), sedation,, laboured respiration and reduced activity
Hazards Identifications / Toxicological Effects
Acute Effects
/ Eye/skin irritation / LD50/LC50 / mouse - 3692 mg/kgd
Chronic Effects / (see note below) / Carcinogenicity / Not listed as carcinogen

*Long-term exposure to respiratory irritants may result in disease of the airways involving difficult breathing and related systemic problems. Limited evidence suggests that repeated or long-term occupational exposure may produce cumulative health effects involving organs or biochemical systems. 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. Neodymium is a member of the so-called light-group (the ceriums) of the rare earths (or lanthanoids). No occupational diseases or cases of poisoning in workers producing rare earth elements have been described. Lanthanoids entering the human body due to exposure to various industrial processes can affect metabolic processes. Trivalent lanthanoid ions, especially lanthanum 3+ and gadolinium 3+, can interfere with calcium channels in human and animal cells.

Exposure Response and First Aid Measures

Skin: /
  • Immediately remove all contaminated clothing, including footwear.
  • 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 fumes or combustion products are inhaled remove from contaminated area.
  • Lay patient down. Keep warm and rested.
  • Prostheses such as false teeth, which may block airway, should be removed, where possible, prior to initiating first aid procedures.
  • Apply artificial respiration if not breathing, preferably with a demand valve resuscitator, bag-valve mask device, or pocket mask as trained. Perform CPR ifnecessary.
  • Transport to hospital, or doctor, without delay.

Ingestion: /
  • If swallowed do NOT induce vomiting.
  • If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain open airway and prevent aspiration.
  • Observe the patient carefully.
  • Never give liquid to a person showing signs of being sleepy or with reduced awareness; i.e. becoming unconscious.
  • Give water to rinse out mouth, then provide liquid slowly and as much as casualty can comfortably drink.
  • Seek medical advice.

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:
