Hazard Summary
Hazard Rating NJDHSS NFPA HEALTH (^) 4 - FLAMMABILITY 0 - REACTIVITY 0 - CARCINOGEN DOES NOT BURN Hazard Rating Key: 0=minimal; 1=slight; 2=moderate; 3=serious; 4=severe Silica, Quartz can affect you when inhaled. Silica, Quartz is a CARCINOGEN. HANDLE WITH EXTREME CAUTION. Contact can irritate the eyes and nose. Exposure to high levels of Silica, Quartz can cause a very serious lung disease called Silicosis with cough and shortness of breath. Very high exposures can cause Silicosis to develop in a few weeks; with lower exposures it may occur over many years. Silicosis may cause death.
If Silicosis develops, chances of getting Tuberculosis are
increased. For more information, consult the Right to Know Hazardous Substance Fact Sheets on SILICA, CRISTOBALITE and SILICA, TRIPOLI.
Workplace Exposure Limits
OSHA: The legal airborne permissible exposure limit (PEL) is: 10 mg/m^3 % Silicon Dioxide +2 (as respirable dust ) averaged over an 8-hour workshift, and 30 mg/m^3 % Silicon Dioxide +2 (as total dust ) averaged over an 8-hour workshift. NIOSH: The recommended airborne exposure limit is 0.1 mg/m^3 (as respirable dust ) averaged over a 10 - hour workshift. ACGIH: The recommended airborne exposure limit is 0.025 mg/m^3 (as the respirable fraction ) averaged over an 8-hour workshift. Silica, Quartz is a CARCINOGEN in humans. There may be no safe level of exposure to a carcinogen, so all contact should be reduced to the lowest possible level.
Determining Your Exposure
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. For each individual hazardous ingredient, read the New Jersey Department of Health Hazardous Substance Fact Sheet, available on the RTK website (http://nj.gov/health/workplacehealthandsafety/right-to- know) or in your facility’s RTK Central File or Hazard Communication Standard file. You have a right to this information under the New Jersey Worker and Community Right to Know Act and 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. 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.
Health Hazard Information
Acute Health Effects The following acute (short-term) health effects may occur immediately or shortly after exposure to Silica, Quartz : Contact can irritate the eyes and nose. Exposure to high levels of Silica, Quartz can cause a serious lung disease called Silicosis with cough, shortness of breath, and changes in the chest x-ray. Chronic Health Effects The following chronic (long-term) health effects can occur at some time after exposure to Silica, Quartz and can last for months or years: Cancer Hazard Silica, Quartz is a CARCINOGEN in humans. There is evidence that Crystalline Silica causes lung cancer in humans and Silica, Quartz causes lung cancer in animals. Many scientists believe there is no safe level of exposure to a carcinogen. Such substance may also have the potential for causing reproductive damage in humans. Reproductive Hazard According to the information presently available to the New Jersey Department of Health, Silica, Quartz has not been tested for its ability to affect reproduction. Other Effects Exposure to Silica, Quartz over a long period of time can cause a very serious lung disease called Silicosis. Simple Silicosis may only cause changes in the chest x-ray. Very high exposures can cause Silicosis to develop in a few weeks; with lower exposures it may occur over many years. Silicosis may cause death. If Silicosis develops, chances of getting Tuberculosis are increased.
Medical
Medical Testing For frequent or potentially high exposure (half the TLV or greater), the following are recommended before beginning work and at regular times after that: Lung function tests Chest x-ray every one to three years If abnormal chest x-ray develops, the following should be done periodically: Skin test for Tuberculosis 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 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.

Spills and Emergencies
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 Silica, Quartz is spilled, take the following steps: Evacuate personnel and secure and control entrance to the area. Eliminate all ignition sources. Moisten spilled material first or use a HEPA-filter vacuum for clean-up and place into sealed containers for disposal. It may be necessary to contain and dispose of Silica, Quartz 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.
Handling and Storage
Prior to working with Silica, Quartz you should be trained on its proper handling and storage. A regulated, marked area should be established where Silica, Quartz is handled, used, or stored. Silica, Quartz is not compatible with OXIDIZING AGENTS (such as PERCHLORATES, PEROXIDES, PERMANGANATES, CHLORATES, NITRATES, CHLORINE, BROMINE and FLUORINE); ACETYLENE; AMMONIA; HYDROGEN FLUORIDE; and CATECHOL.

GLOSSARY
ACGIH is the American Conference of Governmental Industrial Hygienists. They publish guidelines called Threshold Limit Values (TLVs) for exposure to workplace chemicals. Acute Exposure Guideline Levels (AEGLs) are established by the EPA. They describe the risk to humans resulting from once-in-a lifetime, or rare, exposure to airborne chemicals. Boiling point is the temperature at which a substance can change its physical state from a liquid to a gas. A carcinogen is a substance that causes cancer. The CAS number is unique, identifying number, assigned by the Chemical Abstracts Service, to a specific chemical. CFR is the Code of Federal Regulations, which are the regulations of the United States government. A combustible substance is a solid, liquid or gas that will burn. A corrosive substance is a gas, liquid or solid that causes destruction of human skin or severe corrosion of containers. The critical temperature is the temperature above which a gas cannot be liquefied, regardless of the pressure applied. 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. ERG is the Emergency Response Guidebook. It is a guide for emergency responders for transportation emergencies involving hazardous substances. Emergency Response Planning Guideline (ERPG) values provide estimates of concentration ranges where one reasonably might anticipate observing adverse effects. A fetus is an unborn human or animal. A flammable substance is a solid, liquid, vapor or gas that will ignite easily and burn rapidly. The flash point is the temperature at which a liquid or solid gives off vapor that can form a flammable mixture with air. IARC is the International Agency for Research on Cancer, a scientific group. Ionization Potential is the amount of energy needed to remove an electron from an atom or molecule. It is measured in electron volts. IRIS is the Integrated Risk Information System database on human health effects that may result from exposure to various chemicals, maintained by federal EPA. LEL or Lower Explosive Limit , is the lowest concentration of a combustible substance (gas or vapor) in the air capable of continuing an explosion. mg/m^3 means milligrams of a chemical in a cubic meter of air. It is a measure of concentration (weight/volume). A mutagen is a substance that causes mutations. A mutation is a change in the genetic material in a body cell. Mutations can lead to birth defects, miscarriages, or cancer. NFPA is the National Fire Protection Association. It classifies substances according to their fire and explosion hazard.

Protective Action Criteria (PAC) are values established by the Department of Energy and are based on AEGLs and ERPGs. They are used for emergency planning of chemical release events. A reactive substance is a solid, liquid or gas that releases energy under certain conditions. STEL is a Short Term Exposure Limit which is usually a 15- minute exposure that should not be exceeded at any time during a work day. A teratogen is a substance that causes birth defects by damaging the fetus. UEL or Upper Explosive Limit is the highest concentration in air above which there is too much fuel (gas or vapor) to begin a reaction or explosion. Vapor Density is the ratio of the weight of a given volume of one gas to the weight of another (usually Air ), at the same temperature and pressure. The vapor pressure is a force exerted by the vapor in equilibrium with the solid or liquid phase of the same substance. The higher the vapor pressure the higher concentration of the substance in air.
