Synonyms: Sodium Monosulfide
Chemical Name: Sodium Sulfide
Date: August 1999 Revision: February 2008
CAS Number: 1313-82-
RTK Substance Number: 1728
DOT Number: UN 1385
Sodium Sulfide is a white, yellow to red or pink crystalline
solid or flake, which discolors on exposure to air and has a
rotten egg odor. It is used in the production of heavy water for
nuclear reactors, as a medication for animals, in dehairing
hides and making rubber, colors and dyes, and in pulp and
paper processing.
f Sodium Sulfide is on the Right to Know Hazardous Substance List because it is cited by DOT and NFPA.
f This chemical is on the Special Health Hazard Substance List.
Eye Contact f Immediately flush with large amounts of water for at least 30 minutes, lifting upper and lower lids. Remove contact lenses, if worn, while flushing. Seek medical attention immediately.
Skin Contact f Quickly remove contaminated clothing. Immediately wash contaminated skin with large amounts of soap and water. Seek medical attention.
Inhalation f Remove the person from exposure. f Begin rescue breathing (using universal precautions) if breathing has stopped and CPR if heart action has stopped. f Transfer promptly to a medical facility.

f Sodium Sulfide can affect you when inhaled and may be absorbed through the skin. f Contact can severely irritate and burn the skin and eyes with possible eye damage. f Inhaling Sodium Sulfide can irritate the nose, throat and lungs causing coughing and/or shortness of breath. f Sodium Sulfide may cause a skin allergy. f Finely divided Sodium Sulfide may explode in air.
No occupational exposure limits have been established for Sodium Sulfide. However, it may pose a health risk. Always follow safe work practices.
f It should be recognized that Sodium Sulfide can be absorbed through your skin, thereby increasing your exposure.
f Read the product manufacturer’s Material Safety Data Sheet (MSDS) and the label to determine product ingredients and important safety and health information about the product mixture. f For each individual hazardous ingredient, read the New Jersey Department of Health Hazardous Substance Fact Sheet, available on the RTK website (www.nj.gov/health/eoh/rtkweb) or in your facility’s RTK Central File or Hazard Communication Standard file. f You have a right to this information under the New Jersey Worker and Community Right to Know Act, the Public Employees Occupational Safety and Health (PEOSH) Act if you are a public worker in New Jersey, and under the federal Occupational Safety and Health Act (OSHA) if you are a private worker. f The New Jersey Right to Know Act requires most employers to label chemicals in the workplace and requires public employers to provide their employees with information concerning chemical hazards and controls. The federal OSHA Hazard Communication Standard ( CFR 1910.1200) and the PEOSH Hazard Communication Standard (N.J.A.C. 12:100-7) require employers to provide similar information and training to their employees.
This Fact Sheet is a summary of available information regarding the health hazards that may result from exposure. Duration of exposure, concentration of the substance and other factors will affect your susceptibility to any of the potential effects described below.
Acute Health Effects The following acute (short-term) health effects may occur immediately or shortly after exposure to Sodium Sulfide :
f Contact can severely irritate and burn the skin and eyes with possible eye damage. f Inhaling Sodium Sulfide can irritate the nose, throat and lungs causing tightness in the chest and/or difficulty in breathing.
Chronic Health Effects The following chronic (long-term) health effects can occur at some time after exposure to Sodium Sulfide and can last for months or years:
Cancer Hazard f According to the information presently available to the New Jersey Department of Health, Sodium Sulfide has not been tested for its ability to cause cancer in animals.
Reproductive Hazard f According to the information presently available to the New Jersey Department of Health, Sodium Sulfide has not been tested for its ability to affect reproduction.
Other Effects f Sodium Sulfide may cause a skin allergy. If allergy develops, very low future exposure can cause itching and a skin rash. f Sodium Sulfide can irritate the lungs. Repeated exposure may cause bronchitis to develop with coughing, phlegm, and/or shortness of breath.
Medical Testing If symptoms develop or overexposure is suspected, the following are recommended:
f Evaluation by a qualified allergist can help diagnose skin allergy f Lung function tests
Any evaluation should include a careful history of past and present symptoms with an exam. Medical tests that look for damage already done are not a substitute for controlling exposure.
Request copies of your medical testing. You have a legal right to this information under the OSHA Access to Employee Exposure and Medical Records Standard (29 CFR 1910.1020).
Mixed Exposures f Smoking can cause heart disease, lung cancer, emphysema, and other respiratory problems. It may worsen respiratory conditions caused by chemical exposure. Even if you have smoked for a long time, stopping now will reduce your risk of developing health problems.

If employees are required to clean-up spills, they must be
properly trained and equipped. The OSHA Hazardous Waste
Operations and Emergency Response Standard (29 CFR
1910.120) may apply.
If Sodium Sulfide is spilled, take the following steps:
f Evacuate personnel and secure and control entrance to the area. f Eliminate all ignition sources. f Collect powdered material in the most convenient and safe manner and deposit in sealed containers. f WATER OR WET METHOD may produce Hydrogen Sulfide gas. f Ventilate and wash area after clean-up is complete. f Keep finely divided Sodium Sulfide out of confined spaces, such as sewers, because of the possibility of an explosion. f It may be necessary to contain and dispose of Sodium Sulfide as a HAZARDOUS WASTE. Contact your state Department of Environmental Protection (DEP) or your regional office of the federal Environmental Protection Agency (EPA) for specific recommendations.
Prior to working with Sodium Sulfide you should be trained on
its proper handling and storage.
f ELEVATED TEMPERATURES (1, o F, 920 o C) or FRICTION can cause explosive decomposition.
f Sodium Sulfide reacts violently with STRONG ACIDS (such as HYDROCHLORIC, SULFURIC and NITRIC); OXIDIZING AGENTS (such as PERCHLORATES, PEROXIDES, PERMANGANATES, CHLORATES, NITRATES, CHLORINE, BROMINE and FLUORINE); STRONG BASES (such as SODIUM HYDROXIDE and POTASSIUM HYDROXIDE); ALUMINUM POWDER; CARBON; and DIAZONIUM SALTS. f Sodium Sulfide reacts with WATER to form Hydrogen Sulfide gas. f DO NOT ALLOW Sodium Sulfide to become completely dry as it may ignite spontaneously. f Store in tightly closed containers in a cool, well-ventilated area away from HEAT. f Use only non-sparking tools and equipment, especially when opening and closing containers of Sodium Sulfide.
