Material Safety Data Sheets purpose

Pyrophoric and other spontaneously combustible substances will generally be identified as such on their product literature, material safety data sheets (MSDSs), or International Chemical Safety Cards (ICSCs). If transported, these substances should be identified as DOT/UN Hazard Class 4.2 materials for shipping purposes and labeled as spontaneously combustible. For pyrophoric substances, the NFPA 704 diamond for container or vessel labeling has a red (top) quadrant with a rating of 4, indicating the highest severity of flammability hazard (NFPA 704, 2001). Note that pyrophoric materials often exhibit one or more other reactivity hazards as well, such as water reactivity. 

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.

The handbook provides ready information on the fire and chemical reactivity of commonly used chemicals. Its purpose is to provide basic information important to the safe handling of chemicals and to help provide guidance in responding to a hazardous materials incident, in particular, incidents involving reactive chemicals and materials posing fire and explosion hazards. The data and information on each chemical have been compiled from several sources, including the CHRIS data base, material safety data sheets from chemical manufacturers and suppliers, and various references cited at the end of this first chapter. This first chapter provides an explanation of the terms used in chemical specific discussions and also provides basic guidance on how to extract information from the handbook. 

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. 

Under the Industrial Safety and Health Law, unlike the Chemical Substances Control Law, all chemical substances including a chemical substance regulated by other laws, such as the Food Sanitation Law in lapan and the Pharmaceutical Affairs Law, and used exclusively for the purpose permitted by such laws must be notified. Notification of a substance is accepted if it shows a negative result for the test and the notification document is complete. On acceptance, the substance can be manufactured and / or imported. If the substance shows a positive result for the test, the competent authority requires that additional tests be performed, such as a chromosomal aberration test, and the provision to workers who handle the substance with the information on safety, handling methods and emergency measures for the substance described in a Material Safety Data Sheet (MSDS). 

Special models and programs are developed for such purposes as health and safety management and assessment, risk analysis and assessment, emission control and detection and quality control. Such a program may, for example, help the user to keep records regarding training, chemical inventories, emergency response plans, material safety data, sheet expiry dates and so on. 

Employers are reqnired to obtain and keep material safety data sheets. They mnst snbmit copies of each MSDS (or a listing of MSDSs that must be maintained) to their local fire department, the LEPC, and the SERC. There is one exdnsicn if a chemical is nsed solely nsed for household, consuma or agn-cultural purposes, notification is not reqnired. However, nnder OSHA regulations, pesticide nsers (except homeowners) mnst have an MSDS for each pesticide they handle. 

Injections into the subcutaneous or intradermal sites do not require that the animals are anesthetized however, intradermal injections are significantly easier when the animals are unconscious or sedated. Metastatic potential does not seem to be affected by anesthetics at this step. Methoxyllurane (Metofane , Pitman-Moore) inhalation anesthetic is relatively inexpensive and effective for this purpose. A homemade anesthesia jar will suffice. Place a small volume of Metofane under a wire screen suspended above the floor of a container with a lid. Mice and rats will be unconscious within 3-5 min and the effects will last less than 5 min. It is crucial that the animals never come into contact with the fluid. Transdermal absorption can be lethal. Also, anyone using this inhalant should also be cognisant of the content within the Material Safety Data Sheets (MSDS) and the chances of pathologies if overexposed. Hint construct the anesthesia jar with a wire mesh that allows feces to drop as this maintains clean conditions. This provides for easier and more complete cleaning of the jar. 

SCHC s purpose is to promote effective communication of chemical hazards. The Society is committed to sharing knowledge and resources to ensure a consistent and uniform approach to assessing and communicating chemical hazards on product labels, material safety data sheet (MSDS), and other product literature and documentation by... 

Workplace exposure to chemical substances and the potential for pulmonary toxicity are subject to regulation by the Occupational Safety and Health Administration under the Occupational Safety and Health Act (OSHA), including the requirement that potential hazards be disclosed on material safety data sheets (MSDS). (An interesting question arises as to whether carbon nanotubes, chemically carbon but with different properties because of their small size and structure, are indeed to be considered the same as or different from carbon black for MSDS purposes.) Both government and private agencies can be expected to develop the requisite threshold limit values (TLVs) for workplace exposure. Also, EPA may once again utilize TSCA to assert its own jurisdiction, appropriate or not, to minimize exposure in the workplace. 

The vehicle used to transport the used battery must be correctly identified following international conventions and local legislation. The appropriate symbols and colors should be used to identify the fact that corrosive, hazardous waste is being transported. A complete Material Safety Data Sheet (MSDS) should also be visible, either attached to the side of the used battery stack or inside the transport vehicle. Appendix 1 contains a sample MSDS sheet, for illustration purposes only. 

For TSCA Inventory purposes, the EPA distinguishes silica gel (CASRN 63231-67-4), and silica fumes, (CASRN 69012-64-2), as unique chemical substances. The EPA takes the position that manufacturers are free to describe these types of substances in promotional literature and in Material Safety Data Sheets (MSDS) in any way they wish. For example, the substance silica, crystalline, has no CASRN assigned to it and does not appear on the TSCA Inventory, but it has been listed by California under Proposition 65 as a carcinogen. The list of various forms of silica in Table 4.1 does not contain forms that are specifically described as being crystalline, but two of them (CASRN 112945-52-5 and 112926-00-8) clearly state that they are not crystalline (crystalline-free). Some suppliers may use these CAS numbers on their MSDS to assure California customers that their products are not subject to a Proposition-65 warning, even though the correct CASRN for TSCA purposes is 76310-86-9. 

The purpose of this section is to ensure that the hazards of all chemicals produced or imported are evaluated, and that information concerning their hazards is transmitted to employers and employees. This transmittal of information is to be accomplished by means of comprehensive hazard communication programs, which are to include container labeling and other forms of warning, material safety data sheets, and employee training. 

Details can be found in EFFA s Code of Practice (CoP, 2008, et seq.), which is described later on. Consignments of dangerous substances (and dangerous goods respectively) must be accompanied by a so-called Material Safety Data Sheet. For this purpose, the International Standard...

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.
