N NALCO Mat rial Safety Data Sh t D scripti n and Explanation of T rms Emergency Telephone Number Medical (708) 920-1810 (24 hours) General The Material Safety Data Sheet (MSDS) has, over the years, become the major media for transmitting health and safety information on chemical products. It is therefore natural that it has been included in the new OSHA Hazard Communication Standard (29CFR 1910.1200) as the key document along with the container label to provide hazard information to employees and employers. These new OSHA regulations require chemical manufac turers to evaluate each chemical produced to determine if it is hazardous. The definition of "hazardous" has been expanded from the usual "flammable, corrosive, oxidizer, explosive, toxic or highly toxic agents, carcinogen, etc." to include combustibles as well as irritants. Consequently, many products that had not previously been classified as "hazardous" now fall into this classification under OSHA. The new regulations require chemical manufacturers and importers to prepare and distribute an MSDS for all hazardous chemicals and that each container of hazardous chemical leaving the workplace be labeled In addition, the chemical manufacturer is to provide a copy of the MSDS to the purchaser at the time of shipment or before. Nalco has established a computerized program to send MSDS's to each purchaser upon receipt of a first order after November 25, 1985. The MSDS will automatically be sent to the attention of the purchasing agent at the "ship to address," A revised MSDS will also be sent to that same address when a change has been made to the MSDS. MSDS's will also continue to be available through your Nalco Sales Representative or upon request to Nalco. The Nalco MSDS complies with all of the requirements of the OSHA regulation In addition, it provides you with all of the important information regarding the safe handling of our products, recommended protection measures, tox icological data, and the status of our products under various federal and state environmental and safety regulations. In short, we have put all of this information into one document for your convenience and easy use. Nalco, as part of our overall commitment to product safety, is providing MSDS's on all of our chemical products regardless of whether the product is hazardous or not The OSHA regulations require an MSDS to be pre pared only for certain hazardous chemicals. This MSDS section description and explanation of terms is designed to assist your interpretation of the MSDS so that you may receive full value from the document Section 1 -- Product Identification This section identifies the Nalco product by Trade Name or Product Number. This is the same trade name or product number that will appear on the product container allowing you to match up the product label with the MSDS. Nalco also provides a generic chemical description of all major ingredients, both hazardous and non-hazardous. This is designed to give your health and safety personnel information on the class of chemistry(s) in our product without compromising the proprietary nature of the formulation. The third part of this section is the National Fire Protec tion Association (NFPA) 704M rating designation This popular rating system is used to give you a quick summary of the hazards of the product regarding health, flam mability, reactivity and other hazards. Based on NFPA definition, an organic product will always have a flam mability rating of at least (1) with inorganics having a rating of (0). Section 2 -- Hazardous Ingredients We have evaluated our formulations for hazardous proper ties and identify those chemical ingredients which we believe cause or contribute to the hazard As required by OSHA, these substances are identified if they are presc nt in quantities greater than 1%, or in the case of car cinogens, greater than 0.1%, or if our hazard evaluation determines a hazard exists at lower concentrations. The hazardous ingredients are identified by specific chemical name and their CAS number (the Chemical Abstract Service number for that specific chemical). To assist your industrial hygiene and safety personnel, Nalco identifies general or relative concentration ranges into which the exact percentage of the hazardous ingredient falls. This should enable your safety pro fessional to evaluate the need for air sampling, employee monitoring, or other protective measures. Since most of our product formulations are proprietary, exact per centages will be given only when there are no trade secret concerns. In a few cases where disclosure of specific chemical name and CAS number of a hazardous ingredient would release trade secrets, we have identified the chemical as "pro prietary" as permitted by the OSHA regulation. In the event of an injury or accident, procedures are established to communicate the specific identity to health pro fessionals who may have need for this information In all NALCO CHEMICAL COMPANY ONE NALCO CENTER a NAPERVILLE. ILLINOIS 60563-11 SB [7QB] 305-1000 DO 086449 CONFIDENTIAL NALCO cases, the hazard information and safe handling recom mendations are provided. S ction 3 -- Precautionary Label Information The drum or product container is labeled showing product identity, health and safety precautions as well as other information on handling and use of the product That por tion of the label which covers health and safety pre cautions is included in this section of the MSDS. In this way, you can easily refer to what is shown on the drum label without actually seeing the container. Empty drums or containers may contain residual product and should be treated in accordance with the label require ment unless the empty container has been properly recon ditioned. By EPA Standards (RCRA - 40CFR 261.7), a container is considered to be "empty" when it contains: 1) no more than 1 inch (2.5 centimeters) of product, or 2) no more than 3% by weight of the total capacity of the con tainer if the container is less than or equal to 110 gallons in size or 3) no more than 0.3% by weight if the container is greater than 110 gallons in size. Empty drums that formerly contained chemicals listed in 40CFR 261.33 (c) must be triple rinsed using a solvent capable of removing the commerical chemical to qualify as "empty." Quantities of chemical greater than those indicated above which remain in the container are considered "wastes" when dis posing of the container and appropriate RCRA regulations will apply. Section 4 -- First Aid Information This section is designed to provide first aid information for the typical routes of exposure. The recommendations should be followed in all cases. If exposure causes unex pected or delayed effects, or severe reaction or injury, you should immediately consult a physician Nalco ALERT, our medical emergency system (312/920-1510) should be called by the attending physician or others. Nalco ALERT operates 24 hours/day, seven days/week and is staffed by trained professionals. S tion 5 -- Health Effects Information This section describes the nature of the hazardous effect resulting from exposure if no first aid or improper first aid is given The primary routes of exposure such as eye, skin, inhalation or ingestion are listed along with the effects that could occur from acute (single) exposure and chronic (repeated) exposure. The most likely exposure for our pro ducts would be due to unsafe practices which result in skin or eye contact from splashes during handling or feeding of the product S ction 6 -- Toxicology Information Our health hazard evaluation for a product is based upon one or more of the following: 1. Results of toxicological tests conducted on a product, 2. Toxicological test results for a product ingredients), 3. Use of test results on a similar formulation or product and, 4. Use of information obtained in the open literature or supplier information for an ingredients). In this Section, we present summaries of results of such toxicity tests. Explanations of results are given as needed. In most cases, results are those from acute, single exposure tests conducted with laboratory animals. As such, it should be remembered that the test procedures are quite stringent so that direct extrapolation of results to comparable human exposure must be viewed in that context The types of acute animal tests which are routinely con ducted include oral, dermal and inhalation lethality studies and eye and skin irritancy studies. The lethality studies involve administration of the chemical to groups of test animals at various graded dose levels and recording mor tality as one end point The mortality-dose response allows for the calculation of the LDM or LC#0 by appropriate statistical methods. The LDS0 is that dose (amount) of chemical usually expressed in grams or milligrams per kilogram of animal body weight (g/kg or mg/kg) which would produce death in one half of a group of animals administered the chemical The LCso is equivalent to LDS0 except it uses concentration rather than dose and is expressed as parts per million (ppm), milligrams per liter (mg/1) or milligrams per cubic meter of air (mg/M3). Oral and dermal tests use LDW while inhalation tests use LCjoIn both cases the smaller the value the more "toxic" the chemical Eye and skin irritancy tests utilize weighted numerical scores to assess degree of injury or irritation. In many instances, such numerical scores are also given descriptive ratings such as mildly or severely irritating Most grading systems are modeled after those described by Draize, et al (referred to in the Bibliography, Section 17) in their original eye and skin irritation test procedures. Results of skin sensitization tests conducted primarily on animals are presented Human data is given if available. Generally, these test results will be for one or more chemicals in a formulation rather than the formulation itself. When available and applicable, results of tests conducted to assess hazards other than lethality, will be provided in this Section under -- "other toxicity results" and "chronic studies." These types of tests include life-time cancer studies, reproduction tests, and tests designed to uncover birth defects (teratology studies). These tests are usually conducted on individual chemical(s) rather than on for mulated products. Other short-term bioassays for changes to genetic cells are run with bacterial and other cells. While these tests identify genetic changes in tissue, the usefulness of the information as a prediction of a similar effect to humans DO 086450 CONFIDENTIAL continues to be a scientific uncertainty. If this data is available, it will be provided in this section. Since OSHA has broadened the criteria for acute health hazards and since the numerical rating is not uniformly accepted by all governmental agencies and scientific bodies, we are including OSHA's definitions below. Highly toxic substance is one having; 1. An oral LD&, of 50 mg/kg or less. 2. A dermal LDM of 200 mg/kg or less. 3. An inhalation LC50 of 200 ppm or less of gas or vapor; or 2 mg/1 or less of mist, fume or dust A toxic substance is one having; 1. An oral LDM between 50 and 500 mg/kg. 2. A dermal LDS0 between 200 and 1000 mg/kg. 3. An inhalation LCS0 between 200 ppm, 2,000 ppm of gas or vapors, or between 2 and 20 tng/1 of mist, fume or dust A eorrosii'e substance is one which causes third degree bums and scar tissue from 4-hour skin contact to rabbits. A skin irritant is one which causes redness and swelling which does not persist and results in a numerical score of 5 out of 8 in greater than 50% of the animals tested. An eye irritant -- under 1910.1200 an eye irritant is one which at a minimum results in a grade 2 redness and/or swelling of the conjunctiva in at least 4 of 6 test animals when tested by the methods described in 16CFH 1500.42 or other appropriate techniques. The maximum attainable score using the Draize procedure is 110 (80 for cornea, 10 for iris, and 20 for conjunctiva). Use of a finite irritation index to assess a chemical's poten tial as an eye irritant, Le. x/110 cannot always be made because of inconsistencies between OSHA's definition and the standard Draize scoring technique. In some instances, an index as low as 2.7/110 is sufficient to warrant the eye irritation hazard statement while in other instances an index of 6/110 would not In cases of conflict such as this we will point them out on the MSDS. This rating system tends to classify many substances as irritants which would not be so classified under other regulations. Section 7 -- Physical and Chemical Properties To assess the physical hazards of our products, we per form appropriate tests using procedures recommended by the American Society for Testing and Materials (ASTM). Their procedure number is identified accordingly. The tests vary depending on the physical form and chemical nature of the product These physical or chemical test results are one of the factors reviewed in determining the need for or type of subsequent toxicological testing. The results are also used to identify hazardous physical proper ties which require labeling according to the Department of Transportation (DOT) regulations or for waste classification for disposal under the Resource Conservation and Recovery Act (RCRA). Section 8 -- Fire and Explosion Information If the product exhibits flammable characteristics, informa tion is provided on the recommended method for fighting fire. Unusual fire or explosion hazards are also givea OSHA 29CFR 1910.1200 and the Department of Transportation (DOT) consider products with flash points of less than 100 degrees Fahrenheit (F) as flammable materials. Chemicals with flash points between 100 degrees F and 200 degrees F are classified as combustible. On the other hand, the Resource Conservation and Recovery Act (RCRA) -- 40CFR 261 subpart C and D define those chemicals with flash points of 140 degrees F and below as ignitable. Section 9 -- Reactivity Information The potential for our products to aggressively react with other commonly found chemicals or to decompose represents a special hazard. Information is provided on possible interaction with other chemicals as well as reac tion of our products on commonly encountered materials of construction used for chemical and feeding handling systems. Section 10 -- Personal Protective Equipment Handling chemicals such as attaching feed pumps or transferring chemicals from one container to another con stitutes the most likely exposure to operating personnel. Recommendations are provided to protect personnel handling product spills, the type of ventilation needed, and the protective equipment (respirator, gloves, goggles, etc.) that should be used. This is one of the most important sections of the MSDS and the overall hazard communication program and should be well understood and put in practice by operating personnel. Section 11 -- Spill and Disposal Information The disposal of wastes generated at a facility is one of the biggest problems facing industry. This section provides information on how to handle and clean up product spills and guidance for proper disposal should our product be considered a "waste" intended for disposal Section 12 -- Environmental Information This section provides information useful for assessing environmental impact of products or product constituents. When available and where applicable, information on parti tion coefficients, Biochemical Oxygen Demand (BOD), and Chemical Oxygen Demand (COD) is presented DO 086451 conftdfnttai Results of acute aquatic bioassays are presented These bioassays, usually conducted on rainbow trout and bluegill sunfish are useful in assessing potential for adverse effects on aquatic vertebrates. Results are usually expressed as 36-hour LC*o values in milligrams per liter water (mg/1) or parts per million (ppm). The LCS0 is the concentration which is lethal to 50% of a group of fish exposed for the time period indicated It is synonymous with the term TLjo (the concentration which would result in the survival of 50% of a given test group). In many instances, 24 and 48 hours LCW values are given When applicable, a 96hour, no-observed effect concentration is presented based upon lack of adverse effects and mortality. While we know of no published list which ascribes a des criptive rating to LCS0 values, listed below are ratings we use as internal guidelines: 96>Hour LCS0 <1.0 ppm >1.0<5.0 >5<10.0 >10<100 >100<1000 >1000 Rating Extremely toxic Highly toxic Toxic Moderately toxic Slightly toxic Essentially non-toxic S tion 13 -- Transportation Information All hazardous chemicals are subject to regulation by the Department of Transportation (DOT). Section 13 identifies the DOT proper shipping name and hazard class for the product, if any. This name will appear on all shipping documents. Many times the name will reflect the hazard and not necessarily the exact chemical name identified in Section 2. DOT hazard classifications are not always in agreement with those of OSHA. Secti n 14 -- Regulatory Information Today chemical products are regulated from the time they are manufactured, during use, should any environmental release occur, and when the material is finally ready for disposal Section 14 provides information on the status of our products under the various federal and state regulations that may govern its manufacture, use or dis posal Specifically, under the OSHA Hazard Communica tion Rule 29CFR 1910.1200, the reason for classifying the product as being hazardous is provided. A "hazardous classification" is triggered by such things as 1) being combustible (flash point 100-200 degrees F), 2) being flammable (flash point less than 100 degrees F), 3) being a skin or an eye irritant, 4) presenting chronic health hazards such as liver damage, nerve damage, etc., 5) listed on the National Toxicology Program (NTP) Annual Report on Carcinogens or found to be a potential carcinogen by the International Agency for Research on Cancer (IARC), 6) or OSHA having an established workplace exposure limit or recommended limits. Threshold Limit Value (TLV) can be established by either OSHA (OSHA uses the term Per missible Exposure Limit (PEL)], the American Conference of Governmental Industrial Hygienists (ACGJH) or by the chemical manufacturer. Three categories of TLVs are recognized: 1) the Threshold Limit Value-Time Weighted Average (TLVTWA) - the time-weighted average concentration for a nor mal 8-hour workday and a 40-hour workweek, to which nearly all workers may be repeatedly exposed day after day, without adverse effect, 2) Threshold Limit ValueShort Term Exposure Limit (TLV-STEL) - the concentra tion to which workers can be exposed continuously for a short period of time without suffering from a) irritation, b) chronic or irreversible tissue damage, or c) narcosis of suf ficient degree to increase the likelihood of accidental injury, impair self-rescue or materially reduce work efficiency, and provided that the daily TLV-TWA is not exceeded A STEL is defined as a 15-minute timeweighted average exposure which should not be exceeded at any time during a workday even if the 8-hour timeweighted average is within the TLV and 4) Threshold Limit Value-Ceiling (TLV-C) -- the concentration that should not be exceeded during any part of the working exposure. We frequently receive questions on the status of our products under other federal environmental laws. For this reason, when applicable, we are providing information on product status under major laws. 1. OSHA Hazard Communication 29CFR 1910.1200 -- These regulations have been discussed previously in this document 2. Other OSHA Regulations -- OSHA has established specific regulations for various chemicals. If these regulations apply to our products, the regulation and its applicability is identified. 3. CERCLA/Superfund 40CFR 117.302 - This Law requires the reporting of spills of certain chemicals when the quantity spilled exceeds certain specified amounts. If Nalco's product contains one of the specified chemicals, the quantity of Nalco product, which must be spilled before the notification require ment is "triggered," is calculated and the chemical is identified. 4. Toxic Substances Control Act (TSCA) -- Only substances that are included on the TSCA 8(b) Inven tory list, have been exempted, or have been cleared through a TSCA premanufacturing notification (PMN) can be legally manufactured and used in the U.S.A. As other sections of TSCA are implemented, other regulations may apply and will be addressed. DO 086452 CONFIDENT TAl nalco 5. If our product require* registration or govern mental clearances for use in intended applications (examples, pesticides under FIFRA, food additives under FDA, drinking water additives, fuel additives under EPA, use in meat and poultry plants under USDA) the status under the appropriate law is indicated. 6. Resource Conservation and Recovery Act (RCRA) -- Our products as sold are not wastes and therefore not covered by this Act However, should someone decide to declare them a waste and discard them, then they must be evaluated to determine how RCRA might cover the waste. This information is provided on our products should they become "a waste." Please refer to com ments in Section 3 of this document regarding empty containers. 7. The Federal Clean Air and Water Acts 40CFR 60 and 61 and 40CFR 401. IS and 116 contain sections which specifically list chemicals for which these regulations apply. If Nalco products contain as ingredients any of the chemicals listed under these sections, they will be identified. This will allow assess ment of their impact, if any, on discharge or emission permits. We also get similar questions regarding the status of our products under state regulations. State laws are becoming more common and it is difficult to cover all the specifics of each state law in this limited space. However, many states (such as Michigan) list those materials which they consider hazardous or use criteria for listing chemicals. Examples of these criteria are the established TLV's by OSHA or ACGIH or the presence of the chemical on a list such as the National Toxicology Program (NTP) Annual Report or International Agency for Research on Cancer (IARC) list for suspect carcinogens. We are identifying those chemicals for which there is an established TLV or that appear on the NTP or IARC lists. Section 15 -- Additional Information There may be additional information available than what is covered in other sections affecting health, safety and regulation of our product Section 15 provides space to present this additional information. Section 16 -- User's Responsibility This section is designed to serve as a reminder that the information provided is of use only if it is transmitted to the persons who handle the product or work in locations where hazardous chemicals are used or stored. The infor mation is developed based on recommended uses for our products. Other applications may warrant additional review. Section 17 -- Bibliography In addition to this MSDS section description, we may find it of value to know the source material used in evaluating our products other than specific toxicity tests or physical/ chemical tests we may have performed.
