Chemicals Material Safety Data Sheets

A practical problem faced by tanneries is that many chemical products are proprietary products. Many suppliers do not specify the chemical composition of the products, so tanneries may have to seek additional information from the chemical suppliers in order to determine the environmental impact of the products they use. Sometimes it is also difficult for tanneries to receive accurate information also from the suppliers of the chemicals. Material safety data sheets generally provide some data on the toxicity of the products to humans and environment, and many tanneries use these as the sole source of information to determine the environmental impact of a certain substance. It can be expected in the EU in the future that tanneries will receive more detailed information about the substances used because of the REACH legislation.

Safety glasses should be worn in the laboratory at all times. Appropriate safety gloves should be used when handling chemicals. Material safety data sheets (MSDS) for all chemicals to be used must be read prior to beginning the experiment. All chemicals should be considered hazardous from the standpoint of flammability and toxicity.

To an experienced operator trained in the handling of industrial chemicals, the dimers present Httle cause for concern in handling or storage. The finished polymer coating presents even less of a health problem contact with the reactive monomer is unlikely. In the ancillary operations, such as cleaning or adhesion promotion, the operator must observe suitable precautions. Before using the process chemicals, operators must read and understand the current Material Safety Data Sheets, which are available from the manufacturers. 

C depending on the reference consulted). Fires may be controlled with carbon dioxide or dry chemical extinguishers. Recommended methods of handlings loadings unloadings and storage can be obtained from Material Safety Data Sheets and inquiries directed to suppHers of acetone.

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.

A brief summary of safety and health hazards follows detailed health hazards, however, should be obtained from producers by requesting Material Safety Data Sheets. Proper protective equipment and exposure hazards should be noted before handling any alkan olamine. Detailed toxicological testing is found in the CTEA Chemical Ingredient Review Board Reports on ethanolamines and isopropanolamines (24). 

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. 

Health and Safety Factors. The Material Safety Data Sheets provided by the suppUers should be consulted for each product. In general, products are aqueous emulsions with low levels of toxicity. Products with high solvent content have mostly been eliminated. Personnel handling the chemicals should always avoid contact of the products with skin and eyes, and avoid exposure to vapors if the product contains volatile components.

Additional information on health and safety aspects should be sought by consulting material safety data sheets available from suppHers of the chemical in question. In addition, most suppHers of bleaching chemicals, upon request, provide on-site training sessions by experts on the safe use and handling of their products.

Neoprene Type TW was shown to have low oral toxicity in rats. The LD q was found to be in excess of 20,000 mg/kg. Human patch tests with Types GN, W, WRT, and WHV showed no skin reactions (169). The FDA status of Du Pont Neoprene polymers is described (172). Although polychloroprene itself has not been shown to have potential health problems, it should be understood that many mbber chemicals that may be used with CR can be dangerous if not handled properly. This is particularly tme of ethylenethiourea curatives and, perhaps, secondary amine precursors often contained in sulfur modified polychloroprene types. Material safety data sheets should be consulted for specific information on products to be handled.

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.
