Material Safety Data Sheets MSDS

Material Safety Data Sheets (MSDS) include the following information Material identification. The name of the product and the manufacturer s name, address, and emergency phone munber must be provided 

Hazardous ingredients. The sheet must give the chemical name for all hazardous ingredients comprising more than 1% of the material. It must list cancer-causing materials if they comprise more that 0.1%. Listing only the trade name, only the Chemical Abstract Service (CAS) number, or only the generic name is not acceptable. 

If applicable, exposure limits are listed in this section of the MSDS. The OSHA permissible exposure limit (PEL) is a legal, regulated standard. Other limits may also be listed. These include recommended exposure limits (REL) from the National Institute for Occupational Safety and Health (NIOSH) and threshold limit values (TLV) from the American Conference of Governmental Industrial Hygenists (ACGIH). Sometimes, short-term exposure and/or ceiling limits are shown. The ceiling limit should never be exceeded. 

Physical properties. These include the appearance, color, odor, melting point, boiling point, viscosity, vapor pressure, vapor density, and evaporation rate. The vapour pressure indicates whether or not the chemical will vaporize when spilled. The vapor density indicates whether the vapor will rise or fall. Odor is important because a peculiar smell is the first indication that something has leaked. 

Fire and explosion hazard data. This section provides the flash point of the material, the type of extinguisher that should be used if it catches fire, and any special precautions.

When processed and used according to manufacturer s recommendations, acetal resins present no extraordinary health risks. Before the use of any plastic material, including acetal, the Material Safety Data Sheet (MSDS) appHcable to the grade in question should be consulted. 

Material Safety Data Sheets (MSDS) issued by suppHers of acetone ate requited to be revised within 90 days to include new permissible exposure limits (PEL). Current OSHA PEL (54) and ACGIH threshold limit values (TLV) (55) ate the same, 750 ppm TWA and 1000 ppm STEL. Eot comparison, the ACGIH TWA values for the common mbbing alcohols are ethyl, 1000, and isopropyl, 400 ppm. A report on human experience (56) concluded that exposure to 1000 ppm for an 8-h day produced no effects other than slight, transient irritation of the eyes, nose, and throat. 

In general, the acute toxicity of halogenated flame retardants is quite low. Tables 11—14 contain acute toxicity information from various manufacturers material safety data sheets (MSDS) for some of the flame retardants and intermediates Hsted in the previous tables. The latest MSDS should always be requested from the suppHer in order to be assured of having up-to-date information about the toxicity of the products as well as recommendations regarding safe handling. 

Human and environmental welfare for lubricants and their use is addressed in Material Safety Data Sheets (MSDS). These MSDS address toxicology and health concerns based on the components in the lubricant as well as indicating the proper response in case of a spik. Environmental ha2ards of the lubricant are covered on European and Japanese MSDS as shown in Table 5. 

Material Safety Data Sheets (MSDS) and the organic peroxides producers recommendations should be followed carefljlly for handling and storage of organic peroxide compositions. 

Table 2 Hsts some of the physical, toxicity, flammabiUty, and reactivity properties of common chemicals (10,13,42,45—51). Also given are some of the quantities specified for reporting spills and for compliance with legislated requirements. The OSHA regulations require that material safety data sheets (MSDS) be developed for all process materials, so that the ha2ard data can be communicated to employees (52). Characteristics of toxicity, flammabiUty, chemical iastabiUty, reactivity and reaction energy, operatiag coaditioas, and corrosive properties of constmction materials must all be considered ia analy2iag ha2ard poteatials of chemicals and chemical operations.

Sihca and aluminosihcate fibers that have been exposed to temperatures above 1100°C undergo partial conversion to mullite and cristobaUte (1). Cristobahte is a form of crystalline siUca that can cause siUcosis, a form of pneumoconiosis. lARC has deterrnined that cristobaUte should be classified as 2A, a probable carcinogen. The amount of cristobahte formed, the size of the crystals, and the nature of the vitreous matrix in which they are embedded are time- and temperature-dependent. Under normal use conditions, refractory ceramic fibers are exposed to a temperature gradient, thus only the hottest surfaces of the material may contain appreciable cristobahte. Manufacturers Material Safety Data Sheets (MSDS) should be consulted prior to handling RCF materials. 

Those engaged in handling sulfuric acid should obtain detailed information on safe handling practices. Material Safety Data Sheets (MSDS) are available from U.S. and European manufacturers. 

Isocyanates. Isocyanates in general are toxic chemicals and require great care in handling. Oral ingestion of substantial quantities of isocyanates can be tolerated by the human body, but acute symptoms may develop from the inhalation of much smaller amounts. The inhalation of isocyanates presents a ha2ard for the people who work with them as weU as the people who Hve in the proximity of an isocyanate plant. Adequate control of exposure is necessary to achieve a safe working environment. The suppHers Material Safety Data Sheets (MSDS) have to be consulted for the most current information on the safe handling of isocyanates. 

Manufacturers of benzene are requited by federal law to pubHsh Material Safety Data Sheets (MSDS) that describe in detail the procedures for its safe handling. Benzene is classified as a flammable Hquid and should be stored away from any potential source of ignition. Fine and explosion hazard data for benzene are shown (91). 

Manufacturer material safety data sheets (MSDS) indicate that the oxygen concentration in bulk storage bins or other enclosed vessels can be reduced by wet activated carbon to a level that will not support life. Therefore, self-contained air packs should be used by personnel entering enclosed vessels where activated carbon is present (68). 

Polyisoprene mbber is relatively nonhazardous, but must be kept away from sparks, open flames, or excessive heat because it will bum. The current Material Safety Data Sheet (MSDS) should always be checked for known hazards before using polyisoprene or any other chemical materials. 

Reactive Chemicals Exposure. The ha2ards associated with exposure to reactive chemicals vary with the chemicals produced. The multitude of chemicals produced electrochemically precludes a detailed discussion of these ha2ards. Material Safety Data Sheets (MSDS) are available from suppHers. Anyone contemplating the production of a chemical must become thoroughly familiar with all safety, health, and environmental aspects of such production.

While material safety data sheets (MSDS) provide important information they may not provide information on all hazards that may be encountered during processing. A review of the MSDS is not a substitute for conducting a process hazards analysis. Additional information to consider should include ... 

Implied is the availability of Material Safety Data Sheets (MSDS) for all products handled by the toller. The assessor should question the distribution system of product information. 

Supplier Notification. In 1989 and subsequent years, suppliers of facilities in SIC codes 20-39 are required to develop and distribute a notice if the mixtures or trade name products that they manufacture or process, and subsequently distribute, contain listed toxic chemicals. These notices are distributed to other companies in SIC codes 20-39 or to companies that sell the product to facilities in SIC codes 20-39. tf a Material Safety Data Sheet (MSDS) is not required for the mixture or trade name product, the notification must be in written form (i.e., letter or attachment to a MSDS). Otherwise, the notice must be incorporated into or attached to the MSDS for that product. The supplier notification requirement began with the first shipment of a product in 1989 and must accompany the first shipment each year thereafter. In addition, a new or revised notice must be sent if a change occurs in the product which affects the weight percent of a listed chemical or if it is discovered that a previous notice did not property identify the chemicals or the percentage by weight. For more information on supplier notification, see Appendix E. 

The required notification must be provided at ieast annually In writing. Acceptable forms of notice are, for example, a letter, product labeling, and product literature distributed to customers. If you are required to prepare and distribute a Material Safety Data Sheet (MSDS) for the mixture under the Occupational Safety and Health Act (OSHA) Hazard Communication Standard, your section 313 notification may be attached to the MSDS or the MSDS may be modified to include the required information. (A sample letter and recommended text for inclusion in an MSDS appear on pages E-4 and E-5 of this appendix.)... 

Any product which you keep a material safety data sheet (MSDS) for, in accordance with the OSHA Hazard Communication Standard, must be reported, if it was present at your facility in the preceding year, at 10.000 pounds or more at any on time. 

Accessing a material safety data sheet (MSDS)... 

Industrial hygiene/toxicology people need to develop acute and chronic toxicology information on all the materials used and produced in the process. This information should also include the potential products of abnormal reactions. The industrial hygiene member of the team should be prepared to explain the toxicology information on the material safety data sheet (MSDS) to the review team. 

The information to be compiled about the chemicals, including process intermediates, needs to be comprehensive enough for an accurate assessment of the fire and explosion characteristics, reactivity hazards, the safety and health hazards to workers, and the corrosion and erosion effects on the process equipment and monitoring tools. Current material safety data sheet (MSDS) information can be used to help meet this requirement but must be supplemented with process chemistry information, including runaway reaction and over-pressure hazards, if applicable. 

Caution All alkali metals react violently upon contact with water. Read all Material Safety Data Sheets (MSDS) very carefully prior to handling of alkali metals and handle these metals only under the direct supervision of trained and qualified personnel. 

The pilot study is likely to use all the same Quality Management tools that were used for the integration framework development (Chapter 5). However, the limited scope of the pilot study enforces some limitations and compromises—it will not be possible to make changes outside of the department covered by the pilot. Any existing interfaces with other departments must remain the same. This will impact the design phases of the work. For example, Material Safety Data Sheets (MSDS) may currently be prepared locally, in the overall project it might be proposed to develop these centrally. However, for the pilot study it will not be possible develop the central resource so the pilot would have to continue to rely on local resources and there will be no efficiency improvement.

The Material Safety Data Sheet (MSDS) is a detailed information bulletin prepared by the manufacturer or importer of a chemical tliat describes tlie physical and healtli hazards, routes of exposure, precautions for safe handling and use, emergency and first-aid procedures, and control measures. Infonnation on an MSDS aids in tlie selection of safe products and helps prepare employers and employees to respond effectively to daily exposure situations as well as to emergency situations. It is also a source of information for identifying chemical hazards.
