Material safety data sheet chemical inventory

Hazardous Chemicals (Material Safety Data Sheet Chemicals) Inventory Reporting Toxic Chemical Release Reporting Expansion of TRI List... 

Trichloroethylene waste is considered hazardous under the federal Resource Conservation and Recovery Act (RCRA) and many state laws. The waste must be stored, transported, and disposed of in accordance with applicable RCRA and state requirements. The reportable quantity (RQ) for releases of trichloroethylene under the Comprehensive Environmental Response, Compensation, and Liability Act (Superfund) is 100 pounds. It is one of several hundred chemicals subject to material safety data sheet (MSDS), inventory, and release reporting under the Emergency Planning and Community Right-to-Know Act (Title 111 of the 1986 Superfimd Amendments and Reauthorization Act, or SARA). 

There are a variety of chemicals that are toxic and used in the drilling fluid makeup. Chromates and asbestos were once commonly used and are now off the market. A mud inventory should be kept for all drilling additives. Included in the inventory are the material safety data sheets (MSDS) that describe each material s pertinent characteristics. The chemicals found on the MSDS sheet should be compared with the priority pollutants and any material should be eliminated if a match is found. The chemicals should also be checked on arrival for breakage and returned to the vendor if defective packaging is found. All mud additives should be housed in a dry area and properly cared for to prevent waste. Chemicals should always be mixed in packaged proportions. Wasted chemicals, ejected to the reserve pit by untrained personnel, can present future liabilities to the operator. 

The Emergency Planning and Community-Right-to-Know Act was signed into law. Companies involved in the production and handling of hazardous materials must submit material safety data sheets (MSDS) or lists of chemicals kept on site. Companies must report inventories of specific chemicals kept in the workplace and an annual release of hazardous materials into the environment. 

An estimate of the toxicity or intrinsic hazard is needed for each material identified in the inventory. Such information for many chemicals in the form of a Material Safety Data Sheet (MSDS) are required by the OSHA Hazard Communication Standard. (Other countries have similar requirements.) Standard hazard-data sources may need to be consulted for those chemical compounds for which no MSDSs are presently available. Adequate hazard data may be lacking for various mixtures that are unique to the plant. For such mixtures, it may be necessary to analyze the contents and then estimate the overall hazard based on the individual components. 

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. 

Major elements of a CHP plan include listing of responsibilities for employers, employees, and a chemical hygiene officer. Also among the items that have to be covered in the plan is the stipulation that every laboratory must have a complete chemical inventory that is updated annually. A copy of the Material Safety Data Sheet (MSDS), which defines each chemical as toxic, carcinogenic, or dangerous, must be on file and readily accessible and available to aU employees 24 hours a day, 7 days a week. The MSDS contains important information for the benefit of laboratory employees. The chemical manufacturer s information as supplied on the MSDS is used to ascertain whether a certain chemical is hazardous. Each MSDS must give the product s... 

An emergency spill response plan should reflect the operations, materials and quantities which are specific to that facility. Inventory should be maintained of all chemicals, and the quantity on site of each. Information on the hazardous characteristics of each chemical may be found on Material Safety Data Sheets (MSDSs), which are required by law to accompany the first chemical shipment. Appropriate responses will depend upon an evaluation of the hazards posed from release of the chemicals specific to each facility. 

The inventory must contain information about the hazards and properties of the chemicals. This inventory is to be checked against the "Substance List". Training must be provided on the safe handling and interpretation of the Material Safety Data Sheet. 

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. 

Information, results, or records concerning employee exposures to harmful substances or agents in the workplace, such as inventories of chemicals, material safety data sheets, and work area sampling results. 

Hazardous chemical identity The identity of the chemicai(s) contained inside the container. The name used may be a common or trade name ( Biack Magic Formuia ), or a chemical name (1,1,1-Trichloroethane). The chemical name is found on not only the label, but also the chemical s material safety data sheet (MSDS) and the company s chemical inventory. Therefore, the chemical identity links these three sources of information. 

Hazardous and toxic substances can be defined as those chemicals present in the workplace that are capable of causing harm (see Figure 23.6). In this definition, the term chemicals includes dusts, mixtures, and common materials such as paints, fuels, and solvents. OSHA currently regulates exposure to approximately 400 substances. The OSHA Chemical Sampling Information file contains a listing for approximately 1,500 substances. The EPA s Toxic Substance Chemical Act Chemical Substances Inventory lists information on more than 62,000 chemicals or chemical substances. Some libraries maintain files of Material Safety Data Sheets (MSDSs) for more than 100,000 substances. It is not possible at this time to address or regulate the hazards associated with each of these chemicals that can potentially be found in the workplace. 

Employers are responsible for the development of a written hazard communication program, a hazardous chemical inventory list, and associated material safety data sheets. This written program should be designed so that it is given to the new employee upon initial assignment. The materials should be site specific, readily accessible by plant personnel, and include an evergreen feature that will keep it up to date. Employers are also required to provide training to employees... 

Storage Requirements for maximum allowable flammable storage by class, incompatibility of chemicals in stock, chemical inventory maintenance. Material Safety Data Sheet (MSDS) location and management, and use of refrigerators, flammable cabinets and bench top. 

A brief history of lab safety education since 1986 at the University of California, San Diego is presented along with the rationale for, and content of the various forms this education has taken. The use of electronic media in regulatory compliance includes environment, health and safety training, chemical inventory control, material safety data sheet repository and chemical hygiene plan documentation. A summary of present efforts and future goals is included. 

Material Safety Data Sheets. MSDS are kept both on paper copies and on-line through the undergraduate lab web pages. We recently created an index of all of the paper copies and are in the process of obtaining electronic versions whenever possible. One of our goals is to have each of the course experiments linked to the safety data sheet for the chemicals used in that lab. Our intention is to have our inventory list on-line and have each chemical name linked to the safety data sheet appropriate for it. Currently the best general MSDS on-line resource that we have found is through the Vermont SIRI web site (Stuart, R. 1997 http //siri.org/). 

Inspect quarterly each work center s Hazardous Chemical Inventory List and corresponding Material Safety Data Sheets to ensure they are current and complete,... 

The Material Safety Data Sheets (MSDSs) are a set of individual data sheets providing related safety information for each hazardous chemical used or produced at the work center. Material Safety Data Sheets are filed in each work center s "Right-to-Know" Station Binder, located in the "Right-to-Know" work stations. Each chemical listed on the Hazardous Chemical Inventory List must have a corresponding MSDS. MSDSs are provided to work centers by the Safety Division any time manufacturers forward new copies or new editions. Work center supervisors are responsible for ensuring that MSDSs are current and available for all chemicals listed on their work center s Hazardous Chemical Inventory List, and that chemicals are not used unless this information is available.
