The data to be listed on the Material Technical Sheet needs to be comprehensive enough for an accurate assessment of the fire and explosion characteristics, reactivity hazards, corrosion or erosion effects, and safety, health, and environmental hazards. 

Health and Safety Issues. Polyesterether elastomers derived from dimethyl terephthalate, butanediol, and Ptmeg are not hazardous according to the published Materials Safety Data Sheets (MSDS) for this elastomer. Polymers of a similar structure containing isophthalic acid are also not considered hazardous. For other copolymer elastomers, the MSDS put out by suppliers should be consulted by potential users before evaluation. One environmental advantage of thermoplastic elastomers of this type is that they are melt-reprocessible and thus scrap and off-specification material and even obselete parts can be easily recycled. Up to 25% by weight of recycled material can be incorporated (see Recycling, plastics). 

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

Safety Data Sheets (SDS) should be produced for all substances and mixtures which meet the harmonized criteria for physical, health or environmental hazards under the GHS and for all mixtures which contain substances that meet the criteria for carcinogenic, toxic to reproduction or target organ systemic toxicity in concentrations exceeding the cut-off limits for SDS specified by the criteria for mixtures (see Table 1.5.1 in Chapter 1.5). The competent authority (CA) may also require SDS for mixtures not meeting the criteria for classification as hazardous but which contain hazardous substances in certain concentrations (see Chapter 3.2). The CA may also require SDS for substances or mixtures that meet the criteria for classification as hazardous for non-GHS classes/end-points. An SDS is a well-accepted and effective method for the provision of information, and may be used to convey information for substances or mixtures that do not meet or are not included in the GHS classification criteria. 

Once a substance has been classified, the hazard(s) must be communicated to target audiences. The main tools of chemical hazard communication are labels and MSDSs (sometimes called Safety Data Sheets (SDSs) and Material Data Sheets (MDSs)) that contain the hazard information. Their purpose is to identify the hazardous properties of chemicals that may constitute a health, property, or environmental risk during normal handling or use. 

As discussed in Chapter 3, the selection of raw materials and chemical reactions is often suggested by chemists, biologists, biochemists, or other persons knowledgeable about the chemical conversions involved. In recent years, with the tremendous increase in awareness of the need to avoid handling hazardous and toxic chemicals, in connection with environmental and safety regulations (as discussed in Sections 1.3 and 1.4), raw materials and chemical reactions are often selected to protect the environment and avoid the safety problems that are evident in Material Safety Data Sheets (MSDSs). For example, recall that when the vinyl chloride... 

Material Safety Data Sheet (MSDS). A document that describes the health and safety hazards associated with a product. It also provides information on the selection of protective equipment, spill response, disposal, and other environmental information, matte agent. A compound which aids in the production of an uneven, uniformly rough surface. MCF. See 1,1,1-Trichloroethane. meat wrapping paper. A specially treated odorless and tasteless paper that resists meat juices, fat and grease, and is easy to remove from any kind of meat. 

It can be seen that cyclohexane satisfies the criteria for HIGHLY Flammable, but not those for toxic or environmental hazards. This solvent does, however, possess the generic ability to cause CNS effects and irritation and this makes the point that the label alone is insufficient to give the user full knowledge of the potential hazards of a substance. More extensive information should be available in the Safety Data Sheet, which is required to be supplied with all substances classified as DANGEROUS under this system. 

The physical and health hazards associated with chemicals should be determined before working with them This determination may involve consulting literature references. Laboratory Chemical Safety Summaries (LCSSs), Matmal Safety Data Sheets (MSDSs), or other reference materials (see also Chapter 3, section 3.B) and may require discussions with the laboratory supervisor and consultants such as safety and industrial hygiene officers. Every step of the waste minimization and removal processes should be checked against federal, state, and local regulations. Production of mixed chemical-radioactive-biological waste (see Chapter 7, section 7.C.1.3) should not be considered without discussions with environmental health and safety experts. 

The GHS includes criteria for the classification of health, physical and environmental hazards, as well as specifying what information should be included on labels of hazardous chemicals as well as safety data sheets.

The Globally Harmonized System of Classification and Labelling of Chemicals (CHS) Presents a brief overview of the United Nations Globally Harmonized System of Classification and Labelling of Chemicals (GHS) for defining and communicating hazard information and protective measures related to the physical, health, and environmental risks of chemicals through product labels and safety data sheets (SDSs). 

When medicines are prepared from raw materials, residues will turn up in the cleaning waste. Some guidance about environmental hazards can be found in the safety information forms (The Safety Data Sheets, see also Sect. 26.3.4) of the different substances. The relevant part of the form is called ecologic information. 

Hazardous and toxic substances are defined as those chemicals present in the workplace which are capable of causing harm. In this definition, the term chemicals includes dusts, mixtures, and common materials such as paints, fuels, and solvents. OSHA currently regulates exposure to approximately 400 substances. The OSHA Chemical Sampling Information file contains listings for approximately 1,500 substances the Environmental Protection Agency s (EPA s) Toxic Substance Control Act (TSCA) Chemical Substances Inventory lists information on more than 62,000 chemicals or chemical substances some libraries maintain files of material safety data sheets (MSDS) for more than 100,000 substances. 

Trichloroethylene waste is considered hazardous under the federal Resource Conservation and Recovery Act (RCRA) and many state laws. The waste must be stored, transported, and disposed of in accordance with applicable RCRA and state requirements. The reportable quantity (RQ) for releases of trichloroethylene under the Comprehensive Environmental Response, Compensation, and Liability Act (Superfund) is 100 pounds. It is one of several hundred chemicals subject to material safety data sheet (MSDS), inventory, and release reporting under the Emergency Planning and Community Right-to-Know Act (Title 111 of the 1986 Superfimd Amendments and Reauthorization Act, or SARA).
