A. General Policy Statement
HAZARD COMMUNICATION PROGRAM
We are firmly committed to providing a safe and healthy work environment. It is a matter of office policy as well as an important public program under the OSHA Act. We have implemented this Hazard Communication Program as outlined herein. Safe handling of hazardous materials is like wearing a seatbelt – expensive and uncomfortable, then, one day, it will save your life. Dr. will have the overall responsibility for coordinating the program for the Health Park Dental office located at 110 S. Tippecanoe Drive, Suite A, Tipp City, Ohio 45371.
ACCESS TO THE WRITTEN PROGRAM
All, or any part of this written Hazard Communication program is available to employees, their designated representatives, the Assistant Secretary of Labor for Occupational Safety and Health (OSHA), and the Director of the National Institute for Occupational Safety and Health (NIOSH). This is available from the person named above for review and copying.
GENERAL Our office will rely on material safety data sheets (MSDS) from our suppliers to meet hazard determination requirements. B. The purpose of this program is to ensure that this office is in compliance with the OSHA Hazard Communication Standard (HCS) 29 CFR 1910.1200. C. Every hazardous substance known to be present in the workplace will be listed on the “hazardous chemicals Inventory”. D. The identity of the substance appearing on the “Hazardous Chemicals Inventory” will be the same name that appears on the manufacturer’s label, in house label, and the MSDS for that substance. E. The “Hazardous Chemicals Inventory” will serve as an index to the MSDS’s files.
MATERIAL SAFETY DATA SHEETS
A. A material safety data sheet (MSDS) containing the information required by the Hazard Communication Standards will be kept for each substance listed on our “Hazardous Chemicals Inventory.” The MSDS will be the most current one supplied by the chemical manufacturer, importer, or distributor. You have the right to view these. B. For each new chemical ordered an MSDS shall be required with the shipment. The chemical’s name shall be added to the “Hazardous Chemicals Inventory” and the MSDS to the MSDS book. C. The MSDS’s are filed ______________ and are readily accessible to employees during working hours.
A material safety and data sheets (MSDS) containing the information required by the Hazard Communication Standards will be kept for each substance listed on our “Hazardous Chemicals Inventory”. Many words have very specific uses in hazardous communications. The following definitions will make it easier for you to read these manufacturers sheets. Don’t try to memorize them. If you see one of those words on a label, use this as a dictionary reference.
Our MSDS sheets are located _________________.
Acute Effect An adverse effect with severe symptoms occurring very quickly, as a result of a single excessive over exposure to a substance.
Acute Toxicity – The adverse effects resulting from a single excessive overexposure to a substance. Usually a figure denoting relative toxicity.
Asphyxiant A vapor or gas that can cause unconsciousness or death by suffocation. Most are associated with a lack of sufficient oxygen to promote life.
Boiling Point Temperature at which a liquid turns to a vapor state. This term is usually associated with the temperature at sea level pressure when a flammable liquid gives off sufficient vapors to promote combustion.
“C” or Ceiling In terms of exposure concentrations, this is the number that should never be exceeded even for a short period, for a substance.
Carcinogen A substance capable of producing cancer in mammals.
CC Cubic Centimeter A volume measurement usually associated with small quantities of liquid. One quart has 946 cubic centimeters.
Chronic Effect An adverse effect with symptoms that develop or recur very slowly, or over long period of time.
Chronic Toxicity The adverse effects resulting from prolonged or repeated exposures to a substance, usually used as an indicator or relative toxicity for exposures over great lengths of time.
Combustible A term used to classify liquids, gases or solids that will burn readily. This term is often associated with “flash point”, which is a temperature at which a given material will generate sufficient vapors to promote combustion.
Concentration A figure used to define relative quantity of a particular material. Such as a mixture in air of 5 ppm acetone in air.
Corrosive A material with the characteristic of causing irreversible harm to human skin or steel by contact.
Decomposition The breakdown of materials or substances into other substances or parts of compounds. Usually associated with heat or chemical reactions.

1. Aerosol, flammable an aerosol that, when tested by the method described in 16 CFR 1500.45, yields a flame projection exceeding 18 inches at full valve opening, or a flashback (a flame extending back to the valve) at any degree of valve opening.
2. Gas, flammable a. A gas that, at ambient temperature and pressure, forms a flammable mixture with air at a concentration of thirteen (13) percent by volume or less; or b. A gas that, at ambient temperature and pressure, forms a range of flammable mixtures with air wider than twelve (12) percent of volume, regardless of the lower limit;
3. Liquid, flammable any liquid having a flashpoint below 100 degrees F (37.8 C), except any mixture having components with flashpoints of 100 F (37.8 C) or higher, the total of which make up 99 percent or more of the total volume of the mixture.
4. Solid, flammable a solid, other than a blasting agent or explosive as defined in 1910.109(a), that is liable to cause fire through friction, absorption of moisture, spontaneous chemical change, or retained heat from manufacturing or processing, or which can be ignited readily and when ignited burns so vigorously and persistently as to create a serious hazard. A chemical shall be considered to be a flammable solid if, when tested by the method described in 16 CFR 1500.44, it ignites and burns with a self sustained flame at a rate greater than one tenth of an inch per second along its major axis.
Flashpoint the minimum temperature at which a liquid gives off a vapor in sufficient concentration to ignite.
Foreseeable emergency any potential occurrence such as, but not limited to, equipment failure, rupture of containers, or failure of control equipment which could result in an uncontrolled release of a hazardous chemical into the workplace.
General Exhaust A term used to define a system for exhausting or ventilating air from a general work area. Not as site specific as localized exhaust.
“G” Gram A unit of weight. One ounce equals about 28.4 grams.
Hazard Chemical Any chemical, which is either a physical or health hazard.
Hazard warning any words, pictures, symbols, or combination thereof appearing on a label or other appropriate form of warning which convey the hazards of the chemical(s) in the container(s).
Health hazard one that include cancer causing, toxic, or highly toxic agents, reproductive toxins, irritants, corrosives, sensitizers, hepatoxins, nephrotoxins, agents that act on hemopoetic system, and agents that damage the lungs, skin, eyes, or mucous membranes.
The term “health hazard” includes chemicals which are carcinogens, toxic, or highly toxic agents, reproductive toxins, irritants, corrosives, sensitizers, hepatotoxins, nephrotoxins, neurotoxins, agents which act on hematopoietic system, and agents which damage the lungs, skin, eyes, or mucous membranes. Appendix A provides further definitions and explanations of the scope of health hazards covered by this section, and Appendix B describes the criteria to be used to determine whether or not a chemical is to be considered hazardous for purposes of this standard.
Ignitable A term used to define any liquid, gas, or solid which has the ability to be “ignited” which means having a flash point of 140 degree F or less.
Immediate use that the hazardous chemical will be under the control of and used only by the person who transfers it from a labeled container and only within the work shift in which it is transferred.
Incompatible Materials that could cause dangerous reactions from direct contact with one another.
Ingestion Taking in of a substance through the mouth.
Inhalation The breathing in of substance in the form of a gas, liquid, vapor, dust, mist, or fume.
Inhibitor A chemical added to another substance to prevent an unwanted change from occurring.

Reducing Agent In an oxidation reaction, this is the material that combines with oxygen. Respiratory System The breathing system, including the lungs and air passages, plus their associated nervous and circulatory components. Responsible party someone who can provide additional information on the hazardous chemical and appropriate emergency procedures, if necessary. Sensitizer A substance that on first exposure causes little or no reaction, however, with repeated exposure would induce a marked response not necessarily to the exposure site. Usually associated with skin sensitization. Specific chemical identity the chemical name, Chemical Abstracts Service (CAS) Registry Number, or any other information that reveals the precise chemical designation of the substance. Specific Gravity The weight of a material compared to the weight of an equal volume of water. Usually expresses a material’s heaviness. A material with a specific gravity of greater than 1.0 will sink to the bottom of water, whereas a material with a specific gravity of less than 1.0 will float on top of water. STEL Short Term Exposure Limit The maximum allowable concentration of a substance that one can be exposed to for less than 15 minutes and not produce adverse health effects. Teratogen A substance or agent, usually associated with cancer, that when exposed to a pregnant female will cause malformation of the fetus. Usually associated with lab animal tests. TLV Threshold Limit Value A term used by the Occupational Safety & Health community to describe the airborne concentration of a material to which nearly all persons can be exposed to day in and day out, and not develop adverse health effects.

TWA Time Weighted Average The airborne concentration of a material to which a person can be exposed over an 8 hour work day (an average). UEL Upper Explosive Limit The highest concentration of a gas or vapor in air that will sustain or support combustion, when an ignition source is present. Unstable (reactive) a chemical which in the pure state, or as produced or transported, will vigorously polymerize, decompose, condense, or will become self reactive under conditions of shocks pressure or temperature. Vapor Density A term used to define the weight of a vapor or gas as compared to the weight of a vapor or gas as compared to the weight of an equal volume of air. Materials lighter than air have a vapor density of less than 1.0, whereas materials heavier than air have a vapor density greater than 1.0. Vapor Pressure A number used to describe the pressure that a saturated vapor will exert on top of its own liquid in a closed container. Usually, the higher the vapor pressure, the lower the boiling point, and therefore the more dangerous the material can be, if flammable. Water reactive a chemical that reacts with water to release a gas that is either flammable or presents a health hazard. Carcinogen a chemical that can cause cancer Corrosive a chemical that causes visible destruction of, or irreversible alterations in, living tissue by chemical action at the site of contact following an exposure period of four hours. This term shall not refer to action on inanimate surfaces. Highly toxic a chemical that can kill you more quickly than a chemical labeled toxic (sed toxic) Irritant a chemical, which is not corrosive, but which causes a reversible inflammatory effect on living tissue by chemical action at the site of contact. Sensitizer a chemical that causes a substantial proportion of exposed people or animals to develop an allergic reaction in normal tissue after repeated exposure to the chemicals
Toxic a chemical falling within any of the following categories: 1. A chemical that can kill you when taken orally When administered by continuous contact for 24 hours (or less if death occurs within 24 hours) with the bare skin 3. When breathed Target organ effects the following is a target organ categorization of effects, which may occur, including examples of signs and symptoms and chemicals that have been found to cause such effects. These examples are presented to illustrate the range and diversity of effects and hazards found in the workplace, and the broad scope employers must consider in this area, but are not intended to be all inclusive. Labeling It is impossible to remember all of the hazardous materials you’ll come in contact with. For this reason, we use hazardous labels. Here are some precautions for our labels. 1. Never remove or deface a hazardous label from a container 2. Make sure the bottle is labeled 3. Make sure all labels are easy to read DENTAL OFFICE SAFETY The following general descriptions deal with several groups of chemicals that may be in products handled in the dental office. The hazard potential depends on the amount of exposure and individual sensitivity. In most dental offices the amounts of chemicals and the risks should be small. The risks and hazards can be further reduced if recommended procedures and precautions are taken. For information on specific products, always refer to the material safety data sheets (MSDS) in Dr. Smith’s office. If any of the information here varies from that on an MSDS, always rely on the MSDS first and foremost. General Precautions Handle chemicals properly in accordance with manufacturer instructions. Avoid skin contact with chemicals. Minimize chemical vapor in the air. Do not leave chemical bottles open. Do not use flame near flammable chemicals. Do not eat or smoke in areas where chemicals are used. When appropriate, wear protective eyewear and masks. Know proper cleanup procedures. Dispose of all hazardous chemicals in accordance with MSDS instructions and applicable local, state and federal regulations.
E. List of Hazardous Chemicals Here is a list of the hazardous materials we use in dentistry and their hazardous component. It is the responsibility of the chemical manufacturer or importer to determine if their material will be hazardous to us. They will note those hazards on their labels (flammable, causes skin irritation, etc.) Review this section for updates once or twice a year. A similar list can be found on the wall next to the staff bathroom.

D. Examples of Safe Handling of Hazardous Materials The following pages list various hazardous materials and HealthPark Dentistry’s safety procedures. Learn them. When you know how to handle these materials safely, have one of the dentists “check you out.” Material Safety Data Sheets are available. The following pages (F1 to Fg) are furnished by OSHA to help you understand the MSDS.
Here are some general precautions: Handle chemicals properly in accordance with manufacturer instructions Avoid skin contact with chemicals Minimize chemical vapor in the air Do not leave chemical bottles open Do not use flame near flammable chemicals Do not eat or smoke in areas where chemicals are used When appropriate, wear protective eyewear and masks Know proper cleanup procedures Dispose of all hazardous chemicals in accordance with MSDS instructions and applicable local, state, and federal regulations. Never throw away any material safety data sheets that come with materials give them to Dr. Smith. He will review them to make sure they are complete. Manufacturers MSDS are available by Dr. Saleh’s office in the blue notebook labeled “MSDS” All incoming hazardous materials/chemicals need to be labeled when unpacked. Acid Etch solutions and gels Examples: Solutions and gels for acid etch techniques associated with placement of composites, sealants, and orthodontic brackets usually contain phosphoric acid. Hazards: Acid burns and possibly sloughing of tissue, eye damage. DO: Handle acid soaked material with forceps or gloves. Clean spills with a commercial acid spill cleanup kit. Avoid skin or soft tissue contact. Rinse with a large amount of running water in case of eye or skin contact. Flammable Gases Examples: Nitrous oxide and oxygen, liquefied petroleum gas (LPG). Hazards: Fire. DO: Test periodically for leaks. Avoid contact between compressed oxygen gas and lubricants or grease. Avoid having sparks or flames near flammable gases.

Salvage amalgam scrap; clean out the dental traps in the assistant carts. Never flush amalgam scraps down the drain. Clean up spilled mercury using appropriate procedures and equipment; do not use a household vacuum cleaner. Place contaminated disposable materials in polyethylene bags, seal, and label. Recycle these bags with a qualified recycler.
Nickel Examples: Nickel containing dental alloys, gold alloys, solders. Particles released during fabrication and grinding of nickel containing alloys. Hazards: Allergic manifestations, irritation to eyes and respiratory systems. DO: Use protective eyewear and NIOSH approved mask when grinding nickel containing alloys. Use high velocity evacuation systems. Nitrous Oxide Hazards: Based on laboratory animal studies, high exposure may cause adverse health effects. DO: Steps should be taken to minimize the vapor concentration of nitrous oxide in the dental suite. Use a scavenging system. Check nitrous oxide machines, lines, hoses, and masks for leakage. Maintain adequate ventilation.
Other Metals Examples: Casting alloys and alloys for amalgam. Hazards: Metal dusts and fumes may irritate eyes and respiratory systems. Contact dermatitis. DO: Wear protective eyewear and NIOSH approved mask while grinding metal prostheses. Organic Chemicals Examples: Alcohols, ketones, esters, solvents, and monomers such as methyl methacrylate and dimethacrylates. The halogen containing organic liquids used in dental offices primarily include chloroform and carbon tetrachloride and some solvents and cleaners. Hazards: Fire, allergic manifestations, contact dermatitis, irritation to mucous membranes, respiratory problems, central nervous system depression, headache, drowsiness, loss of consciousness, nausea, liver and kidney damage, possible mutagenesis. DO: Avoid skin contact Avoid excessive inhalation of vapors. Work in well ventilated areas. Use forceps or gloves when handling contaminated gauze or brushes. Keep containers tightly closed when not in use. Store containers on flat sturdy surfaces. Clean outside surfaces of containers after use to prevent residual material from contacting the next user. Use a commercially available flammable solvent cleanup kit in case of spills. Photographic Chemicals Hazards: Contact dermatitis, irritation of eyes, nose, throat and respiratory system from vapors and fine
particulates of chemicals. DO: Use protective eyewear. Minimize exposure to dry powder during mixing of solution. Avoid skin contact with photographic chemicals and solutions by wearing heavy duty rubber gloves. Work in well ventilated areas. Clean up spilled chemicals immediately. Wash off chemicals with large amounts of water and a pH balanced soap if contact occurs. Store photographic solutions and chemicals in tightly covered containers. Plaster and other gypsum products Examples: Gypsum products contain silica and calcium sulfate. Hazards: Irritation and impairment of respiratory system. Silicosis. Irritation of the eyes. DO: Use plaster and other gypsum products in areas equipped with an exhaust system. Use protective eyewear and NIOSH approved mask while handling powders or trimming models. Minimize exposure to powder during handling. Caution Every liquid should be in a marked container. The container must have a warning label clearly displayed. If you transfer a liquid from one container that has a warning label to a second container, it is your responsibility to make sure that this second container has the same warning label affixed to it also.

J. Proper Labeling Many chemicals used in dentistry are dangerous. The label on the bottle helps you to know when to be careful handling an item. To protect yourself and others: 1. Never deface or remove a Label from a container 2. If you change a liquid or other dangerous material from one container to another, be sure to duplicate and fix a copy of the label on the new container. 3. Some items will need a label a. Any waste container that could hold contaminated waste b. Any container holding reusable contaminated instruments c. The refrigerator that contains dental supplies d. Washer 4. If a container is not labeled let Dr. Smith know. You and he will decide on the proper label. Dr. Smith is responsible for assuring compliance with this labeling requirement in accordance with 29CFR 1910. 1200. 5. All containers of hazardous chemical, which are the responsibility of this office, will be labeled with at least the following information: Identity of the hazardous chemical(s) Appropriate hazard warnings Manufacturer’s or distributor’s name and address 6. Such containers may also be placed in a designated location where the location is labeled and the containers are returned to that designated location after use. Incoming shipments of chemicals shall be reviewed for appropriate labeling and then determine if there is an MSDS available for each chemical received. 7. Read the label on every material the first time you use it 8. The words “caution,” “danger,” “harmful if absorbed by skin,” etc. are precautionary statements and do no identify specific hazards. 9. No hazardous chemicals will be accepted for use in the facility, or shipped to any outside location, unless labeled with at least the following information: 10. When transferring a product to an unlabeled container place a copy of the original label on the new container Identity of the hazardous chemical(s) Appropriate hazard warnings Name and address of the chemical manufacturer, importer, or other responsible party Labels can be confusing to read. Here are some hints to help you. 1. The effectiveness of a disinfectant is determined by how quickly (if at all) it can kill M. Tuberculosis. The contact kill time can vary from 3 to 9 minutes. 2. Some disinfectants need to be diluted. Others are used full strength. Read carefully. 3. Many disinfectants work better at higher temperatures. Never heat a disinfectant. Centigrade can be converted to Fahrenheit if you remember 20 degrees Celsius = 68 degrees Fahrenheit and 25 degrees Celsius = 77 degrees Fahrenheit.
If a label doesn’t include all the necessary information, send them a copy of the following letter:
Dear Sir or Madam: I purchased ____________________ of (amount/size) _______________________________ on ______________ (name of product) (date) from your company. I took delivery of the product on ____________ (date) but did not receive any Material Safety Date Sheets (MSDS) with my order. Please send me the appropriate MSDS immediately so I will be in compliance with OSHA regulations regarding training of my employees about the hazards of this product. Thank you for your cooperation. Sincerely,
K. Hazardous Waste Pick Up At present we use sharps containers (red plastic container on each C&S area). For pick up, sharps containers sealed with red cap go in Biohazard box under C&S on Pierson side. Pick ups are last Tuesday of every month.
