Potassium Permanganate is an odorless, dark purple, sand- like solid. It is used in solutions as a disinfectant, deodorizer, bleaching agent, and in air and water purification.
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 and training concerning chemical hazards and controls. The federal OSHA Hazard Communication Standard, 1910.1200, requires private employers to provide similar training and information to their employees.
RTK Substance number: 1578 Date: March 1986 Revision: May 2002
The following exposure limits are for Manganese :
OSHA: The legal airborne permissible exposure limit (PEL) is 5 mg / m^3 , not to be exceeded at any time.
NIOSH: The recommended airborne exposure limit is 1 mg / m^3 averaged over a 10-hour workshift and 3 mg / m^3 , not to be exceeded during any 15 minute work period.
ACGIH: The recommended airborne exposure limit is 0.03 mg / m^3 (as the respirable fraction ) averaged over an 8-hour workshift.
This Fact Sheet is a summary source of information of all potential and most severe 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.
The following acute (short-term) health effects may occur immediately or shortly after exposure to Potassium Permanganate :
The following chronic (long-term) health effects can occur at some time after exposure to Potassium Permanganate and can last for months or years:
If symptoms develop or overexposure is suspected, the following are recommended:
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 OSHA 1910.1020.
Unless a less toxic chemical can be substituted for a hazardous substance, ENGINEERING CONTROLS are the most effective way of reducing exposure. The best protection is to enclose operations and/or provide local exhaust ventilation at the site of chemical release. Isolating operations can also reduce exposure. Using respirators or protective equipment is less effective than the controls mentioned above, but is sometimes necessary.
In evaluating the controls present in your workplace, consider: (1) how hazardous the substance is, (2) how much of the substance is released into the workplace and (3) whether harmful skin or eye contact could occur. Special controls should be in place for highly toxic chemicals or when significant skin, eye, or breathing exposures are possible.
In addition, the following control is recommended:
Good WORK PRACTICES can help to reduce hazardous exposures. The following work practices are recommended:
Q: What are my chances of getting sick when I have been exposed to chemicals? A: The likelihood of becoming sick from chemicals is increased as the amount of exposure increases. This is determined by the length of time and the amount of material to which someone is exposed.
Q: When are higher exposures more likely? A: Conditions which increase risk of exposure include dust releasing operations (grinding, mixing, blasting, dumping, etc.), other physical and mechanical processes (heating, pouring, spraying, spills and evaporation from large surface areas such as open containers), and "confined space" exposures (working inside vats, reactors, boilers, small rooms, etc.).
Q: Is the risk of getting sick higher for workers than for community residents? A: Yes. Exposures in the community, except possibly in cases of fires or spills, are usually much lower than those found in the workplace. However, people in the community may be exposed to contaminated water as well as to chemicals in the air over long periods. This may be a problem for children or people who are already ill.
Q: What are the likely health problems from chemicals which cause mutations? A: There are two primary health concerns associated with mutagens: (1) cancers can result from changes induced in cells and, (2) adverse reproductive and developmental outcomes can result from damage to the egg and sperm cells.
Q: Can men as well as women be affected by chemicals that cause reproductive system damage? A: Yes. Some chemicals reduce potency or fertility in both men and women. Some damage sperm and eggs, possibly leading to birth defects.
Q: Who is at the greatest risk from reproductive hazards? A: Pregnant women are at greatest risk from chemicals that harm the developing fetus. However, chemicals may affect the ability to have children, so both men and women of childbearing age are at high risk.

Industrial Hygiene Information Industrial hygienists are available to answer your questions regarding the control of chemical exposures using exhaust ventilation, special work practices, good housekeeping, good hygiene practices, and personal protective equipment including respirators. In addition, they can help to interpret the results of industrial hygiene survey data.
Medical Evaluation If you think you are becoming sick because of exposure to chemicals at your workplace, you may call personnel at the Department of Health and Senior Services, Occupational Health Service, who can help you find the information you need.
Public Presentations Presentations and educational programs on occupational health or the Right to Know Act can be organized for labor unions, trade associations and other groups.
Right to Know Information Resources The Right to Know Infoline (609) 984-2202 can answer questions about the identity and potential health effects of chemicals, list of educational materials in occupational health, references used to prepare the Fact Sheets, preparation of the Right to Know Survey, education and training programs, labeling requirements, and general information regarding the Right to Know Act. Violations of the law should be reported to (609) 984-2202.
ACGIH is the American Conference of Governmental Industrial Hygienists. It recommends upper limits (called TLVs) for exposure to workplace chemicals.
A carcinogen is a substance that causes cancer.
The CAS number is assigned by the Chemical Abstracts Service to identify a specific chemical.
A combustible substance is a solid, liquid or gas that will burn.
A corrosive substance is a gas, liquid or solid that causes irreversible damage to human tissue or containers.
DEP is the New Jersey Department of Environmental Protection.
DOT is the Department of Transportation, the federal agency that regulates the transportation of chemicals.
EPA is the Environmental Protection Agency, the federal agency responsible for regulating environmental hazards.
A fetus is an unborn human or animal.
