Health and safety information

Health and safety information is available from the manufacturer of every adhesive sold in the United States. The toxicology of a particular adhesive is dependent upon its components, which mn the gamut of polymeric materials from natural products which often exhibit low toxicity to isocyanates which can cause severe allergic reactions. Toxicological information may be found in articles discussing the manufacture of the specific chemical compounds that comprise the adhesives. 

Workers in the metals treatment industry are exposed to fumes, dusts, and mists containing metals and metal compounds, as well as to various chemicals from sources such as grinding wheels and lubricants. Exposure can be by inhalation, ingestion, or skin contact. Historically, metal toxicology was concerned with overt effects such as abdominal coHc from lead toxicity. Because of the occupational health and safety standards of the 1990s such effects are rare. Subtie, chronic, or long-term effects of metals treatment exposure are under study. An index to safety precautions for various metal treatment processes is available (6). As additional information is gained, standards are adjusted. 

Information on health and safety considerations cited herein for Ryton PPS powders and pellets can be found in Reference 157. Ryton PPS [26125-40-6] is listed in the Toxic Substance Control Act (TSCA) Inventory of Chemicals. 

All the PMBs are Hsted on the U.S. EPA s Toxic Substances Control Act NonConfidential Chemical Substances Inventory (Table 8). In the early to mid-1980s, pseudocumene, mesitylene, hemimellitene, and trimethylbenzene were coveted by TSCA Section 8(a) Preliminary Assessment Information Rule (PAIR) reporting requirements (22) and by TSCA Section 8(d) for health and safety data (23). Mesitylene is the subject of a test rule subacute oral toxicity and subchtonic oral toxicity in tats were underway in 1994 (24). The Safe Drinking Water Act (SDWA) allows monitoring for pseudocumene and mesitylene at the discretion of the State (25). Of the PMBs, only pseudocumene is subject to SARA Tide III section 313 annual release reporting (26). 

Potassium compounds commonly used in ferti1i2ers, eg, KCl and K SO, are not considered to be ha2ardous substances. Detailed information concerning health and safety precautions recommended for a specific, industrially produced potassium chemical can be obtained by contacting a manufacturer direcdy. Principal potassium chemical producers are Hsted in buyers guides pubHshed aimually by chemical trade maga2ines (52). 

AH of the toxicity data on MDA have been collected using either 4,4 -MDA or the corresponding hydrochloride salt. The information discussed in this section can also be used for commercial products containing MDA or PMDA. Because MDA is a potentially ha2ardous chemical, worker exposure should be kept to a minimum. For complete health and safety information on MDA consult references 46 and 56—59. 

Many more suppHers and information about their product line can be obtained from compilations such as the Modem Plastics Pmyclopedia (1) and the Thomas Register of Mmerican Manufacturers (2). The choice of a release agent depends on the process conditions involved and the nature of the contacting substrates (3). Apart from the obvious ease of release, other important requirements are minimal buildup of residues on mold substrate, minimal effect on the molded article, adequate film-forming abiHty, compatibiHty with secondary operations and other processing parameters, health and safety requirements, and cost. 

Tables 2, 3, 4, 5, and 6 contain information concerning the physical properties, solvent characteristics (9—11), economic and production data (12,13), and health and safety characteristics of common industrial solvents (14).

The National Safety Council, National Fire Protection Association, and other similar organizations pubHsh technical information that describes general safety practices for use during the testing, handling, storage, and transport of sulfur (21,36—40). Each of these pubHcations include a Hst of references for additional health and safety information. 

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. 

When used judiciously, the advantages of QRA can outweigh the associated problems and costs. Companies that prudently commission QRAs and conscientiously act on the resulting recommendations are better off for two reasons (1) they have a better base of information to make decisions and (2) their judicious use of QRA technology represents another demonstration of responsible concern for the health and safety of workers and the public. However, companies should resist the indiscriminate use of QRA as a means to solve all problems since this strategy could waste safety improvement resources, diverting attention from other essential safety activities. Once executives are able to interpret and use QRA results, they will appreciate that the quality of their decisions rests largely on their ability to understand the salient analysis assumptions and the limitations of the results.

The motivation for ensuring good indoor air quality should be obvious. The Occupational Safety and Health Act of 1970 emphasizes the need for standards to protect the health and safety of workers. To fulfill this need, the National Institute for Occupational Safety and Health (NIOSH) has developed a strategy for disseminating information that assists employers to protect their workers from workplace hazards. This strategy includes the development of Special NIOSH Hazard Reviews, which support and complement the major standards development and hazard documentation activities of the Institute. These documents deal with...

You will find MSDS-type chemical health and safety information from the National Toxicology Program. Chemical searches can be performed by chemical name, synonym, or CAS (Chemical Abstract Service) number. 

Hazardous Substances Data Bank (HSDB) on compact disc from the Canadian Center for Occupational Health and Safety (can buy at CCOHS web site). "The HSDB(R) (Hazardous Substances Data Bank(R)) database contains data profiles on 4,500 potentially toxic chemical substances. It is created and updated by specialists at the U.S. National Library of Medicine. Compiled from an extensive range of authoritative sources, HSDB is widely recognized as a reliable and practical source of health and safety information. Much of the data is peer reviewed.
