Slide1:  Hazard Communication Online Training ENTER Slide2:  The HazCom Standard Protects Workers To comply with the Illinois Department of Labor regulations, ISU recognizes OSHA regulations. The OSHA HazCom standard requires ISU to protect its workers from the dangers of hazardous materials in the workplace. As a means to protect you, this online training has been developed to cover the basics of the University program. Following the online training is a short quiz, to be submitted. Slide3:  Written Policy ISU has developed a written Hazard Communication Program that is also available to be viewed by all applicable employees. Your supervisor has a copy tailored to your worksite. This lists the specific means of communicating hazards to you about chemicals! If you are unsure of its whereabouts, ask your supervisor. HazCom is about Material Safety:  HazCom is about Material Safety Hazard Communication involves the communication of hazards about chemicals to employees, also known as the “Right To Know”. ISU has a HazCom program that each affected employee should be familiarized with. It is the responsibility of the department, as well as your own to handle chemicals safely, understand chemical labels, and understand the MSDS. Your “Right To Know”:  Your “Right To Know” As part of the “Right To Know” program, the following will be looked at: 5 Elements of Your RTK Program Your RTK Program Chemical Inventory MSDS Labeling Written Policies Training & Safety Awareness Slide6:  Let’s Get Started!!! Slide8:  MSDS Give You Detailed Information Material Safety Data Sheets give you more information than what is on the label. The information includes: Chemical name and common or brand name Emergency and first-aid procedures List of physical and chemical characteristics Safe Handling Health & Physical Hazards Date of preparation of MSDS or last change to it Control measures (ie. PPE) Routes of entry PEL-Permissible Exposure Limit Slide9:  MSDSs are Always Available A Material Safety Data Sheet comes with every ISU purchase. The supervisor or department has a designated area where the MSDSs are to be located. If you cannot locate the MSDS, contact your supervisor. Your supervisor will call to locate one to make it readily available and accessible to all employees. Slide10:  Labels The label on a bleach container tells you the contents, the hazard associated with the chemical, and what part of your body it affects. The unlabeled container could be water or it could be a strong acid. You do not know what it is so you do not know what precautions to take. Remember, you should never remove a label from a container! If you have any doubt about a label, contact your supervisor or EHS. Slide11:  Labels Provide Basic Information The label must have the following: The chemicals name Hazards of the chemicals The manufacture’s name and address If a label gets removed, destroyed or covered, you must put a new label with the above information on it H2O2 Hazards: Siigma Manf. Slide12:  Secondary Labels Protect Others Make sure others have the benefit of the same information that you had. If you put some chemical into a new container, label it with information from the original label. Only containers that you fill and use up yourself over one shift may be with out labels. What is hazardous? :  What is hazardous? Click on the substance you would consider most hazardous. Labeled container of bleach Unlabeled container of bleach Right! The less you know about a material, the more hazardous it is to you. This container is acceptable, you know what it is! What is Considered A Hazard?:  What is Considered A Hazard? Physical hazard: Combustible liquid Compressed gas Explosive Flammable Organic Peroxide Oxidizer Pyrophoric Unstable Water-reactive Health hazard: Carcinogens Toxic or highly toxic Reproductive toxins Irritants Corrosives Sensitizers Hepatotoxins Nephrotoxins Neurotoxins Damage to lung, skin, eyes mucous membranes Agents that act on hematopoietic system Slide16:  Hazardous Materials are used all over Campus The following are some of the hazardous materials found on campus: Asbestos Chlorine Cleaners Freon Paint Solvents Sulfuric Acid Water treatment chemicals Physical and Health Hazards:  Physical and Health Hazards Physical state is one of the factors in determining how hazardous a material is and in deciding what precautions, such as personal protective equipment, are necessary. The physical state affects the hazards Materials whose physical state can be hazardous include: :  Materials whose physical state can be hazardous include: Combustible liquids (Low flashpoints between 100°F-200°F) Compressed gas (Gases in containers under pressure) Explosives (Substance that react rapidly and violently) Flammable (Materials with flashpoint below 100°F) Oxidizers (Materials that give off oxygen and simulate combustion Slide19:  Make you sick (toxic/Irritant) ie. Silica Gel, glycine Catch fire or explode (flammable, combustible, or reactive chemicals) ie. Pine oil, gasoline BOOM!! Hazardous Chemicals Affect you: Click on the buttons to see the effects hazardous chemicals have on you. Chemicals affect the body:  Chemicals affect the body Chemicals that enter your body affect it. Different kinds and doses of chemicals can have different effects. The effects can be acute or chronic and also systematic or localized. Let’s take a closer look at the differences!! What is the difference?:  What is the difference? Localized Systematic Acute Chronic Site of contact On body This is like an organic coming in contact with your skin and burning it! Widespread Throughout body Short-term Health problems Long-term Health problems This is like inhaling vapors and causing damage to your lungs This is like the effects alcohol has on the brain and kidneys. This is like the effects of alcohol on the liver over time. Chemicals build up in the body:  Chemicals build up in the body Some chemicals travel in the body to a particular organ where they build up. You call this organ the chemical’s target organ. While there, the chemical may prevent that organ or body system from working at its best. Carbon monoxide targets the blood Lead targets the blood, nervous, and reproductive system What are the routes of entry?:  What are the routes of entry? How do chemicals enter the body? Check each to look for the best answer Breathing is the only important way chemicals enter the body Most commonly by breathing but also by passing through the skin (cuts or rashes), or by swallowing. There is a better answer, check the other choice. Yes! You can prevent chemicals from entering your body if you are careful, follow safe work practices, and wear PPE when necessary. Beware of Oxygen in the Atmosphere:  Beware of Oxygen in the Atmosphere Asphyxiation can occur through inhalation if there is not enough oxygen (O2) in the area or if something prevents your body from getting the oxygen it needs. This happens when gas fills up a room or space and pushes all the air out, there will not be enough oxygen to breathe. Asphyxiation decreases the amount of oxygen to your brain. This can damage the brain or cause death. Example: Carbon Monoxide attaches to blood cells and prevents the cells from carrying O2 to the rest of the body, this is a chemical asphyxiant Exposure to Chemicals:  Exposure to Chemicals An exposure is the amount of a chemical you come in contact with. This is usually measured by its concentration in the air. Skin exposure is more difficult to measure than exposure through breathing. Click on Each to see who is most affected by exposure:  Click on Each to see who is most affected by exposure Yes! The smaller person is likely to take in a bigger dose per pound of body weight. Not exactly, the larger person may still be affected but less extreme. Be Aware of your Surroundings!!:  Be Aware of your Surroundings!! Use primarily sight and monitoring devices to detect for hazard. Smell is an unreliable indicator of chemicals. You may get used to the smell and no longer be able to detect it. Also, some chemicals do not have a smell! Example: The presence of Radon & Asbestos can only be determined by actual tests. Carbon Monoxide cannot be detected by smell either. Chemicals Affect you!:  Chemicals Affect you! Inhalation Ingestion Absorption Chemicals can enter your body in 3 different ways. So be aware! Dusts, Mists, and Gases can be hazardous:  Dusts, Mists, and Gases can be hazardous Dusts, mists, vapors, gases, droplets, and fumes all float in the air you breathe. They can settle on your skin, or get into your eyes, nose, lungs, mouth. They can irritate, damage, or build up in your body. A common dust like flour or even fluorescent bulb dust can irritate your nose, throat, and lungs if you inhale a lot of it. Liquids Can Irritate or Burn:  Liquids Can Irritate or Burn Liquids can spill, run, splatter, and splash. Chemical burns or irritation can occur if certain liquids splash in your eyes or if they came into contact with it. Skin contact with some chemicals can produce rashes or your skin can absorb them making you ill. Check each to see which is right:  Check each to see which is right Click on each precaution to see which is the most appropriate for non-volatile liquids: Splash proof goggles, chemical protective gloves Gas-tight goggles or full-face respirator, chemical protective clothing, store in cool, well ventilated area Use a wet mop or HEPA vacuum, to clean up spills, wear a HEPA filtered respirator, and pour out the contents under an exhaust hood Right! Splash proof goggles will prevent chemicals from touching your skin or eyes WRONG! WRONG! Gases/Vapors Float and Move in Air :  Gases/Vapors Float and Move in Air Gases float in the air at normal temperatures and pressures. Because gases float, they are hard to contain if released. Also, they move in air, you can inhale them. This is dangerous if they are poisonous. Gases can also irritate or burn tissue they contact. Chlorine is not only a poison by inhalation, it is also very irritating to the skin. Vapors can fuel a fire:  Vapors can fuel a fire Some organic substance such as alcohol and gasoline, are good fuel for fires. You call the temperature at which enough liquid evaporates to fuel a fire the vapor’s flash point. The warmer the room, the more a liquid will evaporate. When there is enough vapor, a spark or other source can ignite it. A fire in an enclosed space can cause an explosion What burns when liquid fuel ignites? :  What burns when liquid fuel ignites? The vapors that have evaporated from the liquid The liquid itself burns Yes! The vapors are what burn when a liquid ignites. Not quite! Compressed Gases are Under Pressure:  Compressed Gases are Under Pressure When you put gas into a container, you push it into a smaller and smaller space. This increases the pressure in the container. If the container leaks, released gas can cause the container to travel at great speeds that can cause injuries. Check this out!:  Check this out! Choose the chemical you think is a gas: Gasoline Not exactly! Gasoline is a liquid at room temperature. However, it may evaporate and release vapors in the air. That’s why you can smell it when you pump gas. Right! Carbon Monoxide is a gas Carbon Monoxide Solids have Form:  Solids have Form Unlike gases, solids take on a definite form at normal temperatures and pressures. If a solid breaks or if you grind it, you produce a dust or a powder. Dusts mix in the air and you can inhale them. This can be hazardous. For example, if you inhale dust from a powdered drain cleaner that is corrosive, it could burn your throat, nose, and lungs. Solids have Form Con’t:  Solids have Form Con’t If you heat a solid to a high enough temperature fumes form. Fumes mix in the air as dust do and you can inhale them. This can be hazardous. When you heat welding flux or other metals, you produce fumes. Flux cord arc welding produces the highest amount of fumes, and shielding metal arc welding the next highest. Click each button to see which one may be present in more than one state::  Click each button to see which one may be present in more than one state: Carbon Monoxide Asbestos Alcohol Not this one Not this one either! Right! Alcohol is a liquid that evaporates into a vapor. Asbestos is a fiber and Carbon Monoxide is a gas. Dusts can be Explosive!!:  Dusts can be Explosive!! At very high concentrations and under the right conditions, some dusts can be explosive. An example is excess organic material created from dumping corn into a silo or small fibers. The smaller the particle, the more reactive the dust. As the materials become smaller, they disperse and remain suspended more easily, increasing the potential for ignition and propagation of the reaction. Click on each button to see which Precaution is most Appropriate for a Dust or Powdered Material: :  Click on each button to see which Precaution is most Appropriate for a Dust or Powdered Material: Splash-Proof Goggles, chemical protective gloves Gas tight goggles or full-face respirator , chemical protective clothing, store in a cool, well ventilated area. Use a wet mop or HEPA vacuum to clean up spills, wear a HEPA-filtered respirator, empty the vacuum under an exhaust hood Not quite Not quite Right! Dusts and powders in the air can harm you when inhaled. The use of wet mopping, HEPA vacuum,and HEPA filtered respirators minimize dust exposure. By-Products can also be produced::  By-Products can also be produced: By-products of work can release hazardous chemicals Hazardous by-products can be the result of mixing different chemicals An example of a hazardous by-product Bleach and ammonia (chlorine gas is formed) Sodium hydroxide and nitric acid (Caustics and acids) Always use Safe Work Practices:  Always use Safe Work Practices Use these safe work practices when handling chemicals: Do not spill, splash, or drop them Use flammable and combustibles away from open flames, sparks, and other sources of heat Do not eat or smoke on the job Wash your hands before going on break or eating Protect yourself from Solvents:  Protect yourself from Solvents Solvents can produce skin irritation or be inhaled as a vapor, which causes adverse health effects. To protect yourself from solvent vapors, first use adequate ventilation. You can absorb solvents through the skin, which also causes adverse health effects. Proper Personal Protective Equipment must be used. Protecting Yourself:  Protecting Yourself The proper Personal Protective Equipment (PPE) must be used to provide barriers between you and the solvents you use. Examples of solvents include: Alcohol Benzene Mineral spirits Trichloroethane Turpentine Click on each statement to see which is right:  Click on each statement to see which is right Solvents are liquids, such as water, that dissolve solids Solvents are liquids, such as water, that dissolve other liquids. Both of the above are true Wrong, keep looking Wrong, Keep looking Yes! Solids are liquids that can dissolve liquids and solids Flammables can ignite at normal Temperatures:  Flammables can ignite at normal Temperatures Most flammable liquids have flash points below 100°F. Combustible liquids have a flash point above 100°F. Such liquids are dangerous because their flash points may be near room temperature. Remember! the lower the flash point, the more hazardous it is. Check to see which Chemical is most Hazardous!:  Check to see which Chemical is most Hazardous! Gasoline whose flash point is -45°F Mineral spirits whose flash point has a range of 105-140°F Yes! The flash point of -45°F means that at extremely cold temperatures, there are enough vapors to ignite. Vapors from gasoline stored in an unheated shed could catch fire. Not exactly! Let’s look at safe work procedures for handling flammables like solvents. Click on each to see the best precautions for using flammables and combustibles.:  Let’s look at safe work procedures for handling flammables like solvents. Click on each to see the best precautions for using flammables and combustibles. Keep them away from other chemicals Keep them away from flames, sparks, hot equipment, or other possible ignition sources Wear gloves and other protective gear Not unless they are also reactive with those chemicals Yes! This is a key safe work practice when you work with flammables. For example, cleaning tools with a solvent in an area where vapors could travel to a water heater and ignite. Not unless the chemicals also have some toxic property Acids and Bases will burn skin and eyes:  Acids and Bases will burn skin and eyes A scale, called the pH scale, measures how acidic or basic a chemical is. Basic (caustic) chemicals have a pH between 8 and 14. Very caustic chemicals can burn your skin and eyes. Ie. Battery acid Sulfuric acid Ie. Saliva Pure water Ie. Bleach Oven cleaner Acids and Bases will burn skin and eyes Con’t:  Acids and Bases will burn skin and eyes Con’t Acids have pH readings between 1 and 6. Very acidic chemicals can also burn the skin and eyes and eat quickly through materials. Inhaled acid or caustic dusts can irritate or burn your respiratory track. Strong Acids and Bases are Corrosive:  Strong Acids and Bases are Corrosive You call the ability of a chemical to eat into a material corrosivity. The farther the pH of a material is from 7, the more corrosive it is. Corrosive materials are hazardous. You must handle them with caution and wear the proper PPE. Check to see which is most corrosive!:  Check to see which is most corrosive! An acid, pH 3 An acid, pH 5 A base, pH 13 Not exactly Not exactly Yes! The most corrosive substance has a pH farthest from 7. A pH of 13 is farther from a pH of 7 than either 3 or 5. Sensitization to a Chemical:  Sensitization to a Chemical Have you ever walked into an area where paints or various chemicals have been used and find yourself becoming itchy, swollen, teary, or even tight in the chest? Some individuals may have worked around these same chemicals for years and then find out that the reaction was suddenly caused by these same chemicals. This is becoming sensitized. Once sensitized, you may react to that chemical for the rest of your life! You may be allergic. Personal Protective Equipment:  Personal Protective Equipment Personal Protective Equipment (PPE) is the barrier between you and the hazardous material you are working with. There are many factors to consider when choosing the proper PPE. For example: Type of PPE Material PPE should consist of Durability Care of PPE Availability of the PPE Expense Let’s take a closer look! Check the MSDS:  Check the MSDS The Material Safety Data Sheet (MSDS) is where you can find out which PPE is right for the particular chemical. This is why it is important to know the location of the MSDS. If questions still arise about the PPE, ask your supervisor. Choose the Proper Material :  Choose the Proper Material PPE is used to protect you from injury to the To prevent skin absorption you must wear personal protective equipment made of the proper material. Choosing the right gloves is especially important to protect the hands. eyes, hands, feet, face, skin, and head. Look on to see the importance of glove use Why you should wear Gloves!:  Why you should wear Gloves! If you try to use regular rubber or latex grocery store gloves, many chemicals can pass right through these. Gasoline and other solvents can eat away the material. Only certain gloves can offer the proper protection of certain chemicals Wear the right PPE:  Wear the right PPE Face protection is necessary when splashing or flying pieces may be encountered and even when working around dust. Equipment that can be used includes: Face shield Safety eye glasses Eye goggles Look on to see the importance of eye protection Why you should wear Eye Protection:  Why you should wear Eye Protection Your eyes are very sensitive & delicate and therefore are easy to injure. You do not want to get chemicals in your eyes! Slide63:  You can inhale many substances in many work operations. You can inhale substances in various forms, including: Vapors Gases Dusts Mists Metallic Fumes Fibers Respirators Protect you from hazards in the Air Respiratory Protection is necessary when hazardous chemicals reach unacceptable levels in the workplace. Respiratory Protection:  Respiratory Protection The highly absorbent tissues in your nose from being damaged Respirators protect: Your lungs if chemicals enter through inhalation. If chemicals enter your lungs it can cause damage or be transported to the rest of your body Slide65:  If you think you need a respirator: If you think you need a respirator, talk with your supervisor or call Environmental Health & Safety located on campus. If a respirator is needed, you will become part of the Respiratory Protection Program. Storage of Chemicals:  Storage of Chemicals Store all chemicals and waste in a safe and secure area. The chemicals should be stored in a structurally sound, good condition container with a tight fitting cap. The container should be compatible with the material. Milk jugs or soda bottles are not acceptable. Leave 10-20% headspace in the container to prevent pressure build up. Chemical Storage:  Chemical Storage Certain chemicals should not be stored together. For example: Halogenated separated from non-halogenated Solids separated from liquids Solvents and low boiling point chemicals generate vapors and should be stored in a well ventilated area. Chemical Waste:  Chemical Waste Remember! Always try to minimize the waste generated by using alternatives when possible. Never dump hazardous or other chemical waste down the drain. For example: Toxic, Flammable, Mercury, Gasoline, Acids, or Caustics Never leave waste in an area that is subject to public contact. Hazardous Waste Pick-up:  Hazardous Waste Pick-up If there is hazardous waste that needs to be disposed of, contact EHS (438-8325) EHS will pick up the waste and store it prior to final disposition. The hazardous waste must be properly labeled. If it is in the original container with original label, that label will be sufficient. If you need a label, contact EHS for a replacement. Include the following information: Content Amount Date Generator Hazards/Precautions Request for Pick-Up:  Request for Pick-Up If you need to have a waste pick-up, contact EHS or download the form from the EHS web page. Complete the form and return it to EHS. Percent concentrations are needed for disposal. If the content is unknown, the generator pays for the analysis. The Waste will be picked up within one week. Ask for Help!!:  Ask for Help!! If you are unsure about the use and handling of a chemical, ask your supervisor or someone who does have knowledge about it. The Environmental Health & Safety Office is here to help you! Contact them at 438-8325 if you have any questions. So should you do next?? What’s Next?:  What’s Next? Your supervisor is to conduct specific training with you regarding the specific duties and exposures you are around. Inquire with your supervisor about job specific HazCom training. Now it is time to see if you understood the basic concepts. Let’s take a short quiz. QUIZ
