The text is revised in view of the facilitation of the student s learning process. Only after this step the addition of instructional adjunct aids is considered. Decisions concerning adding aids take both the function of the printed materials (e. g. self-instmctional material or handbook material) and student characteristics (learning strategies, level of external regulation needed) into account for a discussion sec [15]. 

Material Safety Data Sheet (MSDS) written or printed material concerning a hazardous chemical, which is prepared in accordance with approved regulations.

Occupational Safety and Health J ct. OSHA regulations deal principally with physical aspects of safety and those things generally associated with accident prevention. These federal regulations deal especially with the need for estabHshed material safety data sheets and the proper labeling of printing inks under the Hazard Communication Laws. 

Outlook. Total 1991 U.S. ink consumption was estimated at about 86 x 10 kg valued at over 3.0 biUion. The demand is estimated to grow at an average of about 3—4% per year in volume (26). The principal changes expected in the 1990s will continue to be in response to environmental and safety concerns and government regulations. The bulk of printing inks use raw materials based on fossil fuels, such as coal (qv) and petroleum (qv). 

A primary source of environmental pollution from printing ink comes from the metal-based pigments used, as well as various resins, waxes, and drying agents that are also part of the inks. These materials are added to inks regardless of the source of the oil. As a result, petroleum inks are just as suitable for landfill disposal under U.S. EPA regulations as are vegetable oil inks. 

The markets for polyetherimides arise to an extent from stricter regulations concerning flammability and smoke evolution coupled with such features as high strength, toughness and heat resistance. Application areas include car under-the-bonnet uses, microwave equipment, printed circuit boards and aerospace (including carbon-fibre-reinforced laminated materials). The polymer is also of interest in flim, fibre and wire insulation form. 

Information on laboratory safety is available from many places. The public library usually has material on federal, state, and local safety regulations. The Index to Books in Print, also available at libraries, lists all material published by subject, author, and title. Scientific book publishers will be glad to add new names to their mailing lists for announcements of new publications on safety. 

Initially, a crystallizer system was installed to recover copper sulfate and recycle the plating rack stripping chemistry for reuse in the printed circuit board plating area. The copper sulfate was then sold to a local copper foil manufacturer as a feedstock material to their process. Through this process, waste sludge was converted to a saleable product and exempted from regulation as a hazardous waste.
