MSDS Materials Safety Data

Go to the Web and develop a list of suppliers along with unit costs for some of the various types of flocculants described in this chapter. Also obtain the MSDS (Material Safety Data Sheets) for these chemicals. Once you have collected the information, develop a relative ranking of unit cost and health risk associated with each. For question 2 you will need information of recommended doses. 

Make a list of chemical flocculating agents and relate each of these chemicals to the specific types of contaminants they are best suited to handle in wastewater. Obtain MSDS (Material Safety Data Sheets) for each of these chemicals. 

MSDS Material Safety Data Sheet - a document that provides pertinent information and a profile of a particular hazardous substance or mixture. An MSDS is normally developed by the manufacturer or formulator of the hazardous substance or mixture. The MSDS is required to be made available to employees and operators whenever there is the likelihood of the hazardous substance or mixture being introduced into the workplace. Some manufacturers prepare MSDS for products that are not considered to be hazardous to show that the product or substance is not hazardous. 

MSDS - Material safety data sheets. Information provided by chemical manufacturers that list the hazards.

All the data on health and fire/explosion hazards for compounds and (if possible) mixtures to be dealt with in a process should be collected in the form of an MSDS (Material Safety Data Sheet). It is common practice for users to require that suppliers attach an MSDS to all batches of materials delivered. 

Even unifying information about a very specific field such as the pharmacology of discrete drugs is a monumental task. The primary reason for this difficulty is the disparity of purpose between various information sources. Consider how different the purposes are ofWDI (World Drug Index) [20], PDR (Physician s Desk Reference) [21], MSDS (Material Safety Data Sheets) [22] and REG (Chemical Abstracts Registry) [23], each of which has a different natural data model.

MSDS (Materials Safety Data Sheets) sheets are available from the suppliers of commercially available reagents, solvents, and other chemical materials anyone performing an experiment should check these data sheets before initiating an experiment to learn of any specific hazards associated with the chemicals being used in that experiment. 

The hypothesis that anions of BP A might be removed by column chromatography with Octolig was considered but not pursued because of the warnings in a MSDS (Material Safety Data Sheet) about hazards of BPA and because the pKa values of BPA were listed as 9.59 and 11.3. 

TLV The TLV or Threshold Limit Value refers to a safe level of exposure by inhalation. The definition was established by the American Conference of Governmental Hygienists. There are several variations or criteria levels for the TLV. As an example, hydrogen sulfide has a TLV for short-term exposure limits (STEL) of 15 minutes of only 5 ppm. Comparing this to the TLV-STEL of 400 ppm for carbon monoxide provides an indication of the need to be extremely careful when H2S is suspected. Under OSHA Standards, and particularly on MSDS (Material Safety Data Sheets) compounds are associated with a time weighted average (TWA) TLV, which is the allowable concentration for an 8-hour continuous exposure period. For firefighting purposes, the short-term exposure is likely more realistic. 

MSDS Material Safety Data Sheet a (legal) document that must accompany any supplied chemical that provides information on chemical content, physical properties, hazards, and treatment of hazards. The MSDS should be considered only a minimal source of information, and cannot replace additional information available in other, more comprehensive sources. 

MSDS (Material Safety Data Sheet) A document required by law to be supplied to a user of a hazardous product, to assist the user in safe use and handling of the hazardous product. 

It is essential to understand the hazards of chemical products so that they can be used safely. Important sources of information for aromatherapists include guidelines from bodies such as RIFM (Research Institute for Fragrance Materials), IFRA (International Fragrance Association), product labels and MSDS (Material Safety Data Sheets). 

MSDS - Material Safety Data Sheets (now usually referred to as SDS, Safety Data Sheets) Suppliers, manufacturers and importers who make up the chain of supply of essential oils to the aromatherapist, and ultimately the client, are responsible for drawing up the MSDS. Each time an oil is repackaged or relabelled, a MSDS should be prepared and relevant additional... 

MSDS Material safety data sheet. Printed material on hazardous chemical substances and/or extremely hazardous substances. An MSDS provides information on physical properties, hazards to personnel, fire and explosion potential, safe handling recommendations, health effects, fire-fighting techniques, reactivity, and proper disposal. It was originally established for employee safety by OSHA...
