Nomination Background: Methylal (CASRN: 109-87-5)
SUMMARY OF DATA FOR CHEMICAL SELECTION METHYLAL CAS NO. 109-87-5 BASIS OF NOMINATION TO THE CSWG The nomination of methylal to the CSWG is based on high production volume and exposure potential. Dr. Elizabeth Weisburger, a member of the American Conference of Governmental Industrial Hygienists (ACGIH) TLV Committee as well as the Chemical Selection Working Group (CSWG), provided a list of 281 chemical substances with ACGIH recommended TLVs for which there were no long term studies cited in the supporting data and no designations with respect to carcinogenicity. She presented the list to the Chemical Selection Planning Group (CSPG) for evaluation as chemicals which may warrant chronic testing: it was affirmed at the CSPG meeting held on August 9, 1994, that the 281 "TLV Chemicals" be reviewed as a Class Study. As a result of the class study review, methylal is presented as a candidate for testing by the National Toxicology Program because of: • potential for occupational exposures based on high production volume (1.2-64 million lbs) and estimate of worker exposure • evidence of occupational exposures based on TLV and other literature documentation • potential for general population exposures based on use as a solvent in consumer products and occurrence in environmental media • suspicion of carcinogenicity based on potential for metabolic release of formaldehyde and positive mutagenicity data • lack of chronic toxicity data. SELECTION STATUS ACTION BY CSWG : 9/25/96 Studies requested : - Carcinogenicity Priority : Moderate to High Rationale/Remarks : - Potential for human exposure - Inhalation route recommended for testing - Consider transgenic mouse model (p53 or TGAC) INPUT FROM GOVERNMENT AGENCIES/INDUSTRY Dr. -

Another purpose was to make an effort to separate biologically produced Se0 from cells. Methods Pseudomonas fluorescens K27 was grown in TSN3 medium (tryptic soy broth with 0.3% nitrate) under anaerobic conditions and the production of elemental tellurium and elemental selenium was observed when amended with inorganic tellurium salts and selenium salts, respectively. The amount of soluble tellurium species in the culture medium also was determined. Samples from a 2.75 L bioreactor were taken after cultures had reached the stationary growth phase and were centrifuged in order to separate insoluble species (elemental tellurium, elemental selenium) from soluble species (oxyanions of tellurium, oxyanions of selenium). -

Preparation of Telluric Acid from Tellurium Dioxide by Oxidation with Potassium Permanganate Frank C. Mathers, Charles M. Rice, Howard Broderick, and Robert Forney, Indiana University General Statement Tellurium dioxide, Te0 2 , although periodically similar to sulfur dioxide, cannot be oxidized by nitric acid to the valence of six, i.e., to telluric acid, H 2 Te04.2H 2 0. Among the many stronger oxidizing agents that will produce this oxidation, potassium permanganate in a nitric acid solution is quite satisfactory. This paper gives directions and data for the preparation of telluric acid by this reaction. The making of telluric acid is a desirable laboratory experiment because (1) tellurim dioxide is available in large quantities and is easily obtained, (2) the telluric acid is a stable compound, easily purified, easily crystallized, and non-corrosive, and (3) students are interested in experimenting with the rarer elements. The small soluibility of telluric acid and the high solubility of both manganese and potassium nitrates in nitric acidi gives a sufficient differ- ence in properties for successful purification by crystallization of the telluric acid. Methods of Analyses Tellurium dioxide can be volumetrically 2 titrated in a sulfuric acid solution by an excess of standard potassium permanganate, followed by enough standard oxalic acid to decolorize the excess of permanganate. The excess of oxalic acid must then be titrated by more of the perman- ganate. The telluric acid can be titrated, like any ordinary monobasic acid, 3 (1911). with standard sodium hydroxide using phenolphthalein as an indicator, if an equal volume of glycerine is added. If any nitric acid is present, it must be neutralized first with sodium hydroxide, using methyl orange as indicator. -

Attorney General Balderas Sues Takata & 15 Automakers Over Dangerous Airbags
FOR IMMEDIATE RELEASE: Contact: James Hallinan January 24, 2017 (505) 660-2216 Attorney General Balderas Sues Takata & 15 Automakers over Dangerous Airbags To date, known Takata airbag IR incidents have injured over 180 people and killed at least 11 in the United States alone Santa Fe, NM – Today, New Mexico Attorney General Hector Balderas announced that he filed a lawsuit this week against Japanese airbag manufacturer Takata and 15 automakers over dangerous and defective airbags that function as fragmentation grenades. Hundreds of thousands of which were installed in cars sold or offered for sale in the State of New Mexico. The lawsuit was filed in the First Judicial District Court in Santa Fe, New Mexico, and it names Takata, Honda, Ford, Toyota, BMW, Mazda, Subaru, Mitsubishi, Nissan, FCA, Volkswagen, Audi, Ferrari, General Motors, Jaguar, and Mercedes-Benz. Attorney General Balderas alleges that the parties knew about, and misrepresented, the existence and extent of the defective airbags, and tried to conceal the defect until the National Highway Traffic Safety Administration (NHTSA) and Congress exposed the full extent of the defective airbags. “In New Mexico, no child should ever be put in danger so international corporations can reap enormous profits,” Attorney General Balderas said. “New Mexico families’ health and safety have been put at dangerous risk by Takata and the automakers, and we will hold them accountable. Corporations who harm New Mexicans will pay for their actions no matter their size or location around the world.” Takata’s airbag systems are installed in millions of vehicles, including vehicles manufactured by the defendant automakers. -

Prohibited and Restricted Chemical List
School Emergency Response Plan and Management Guide Prohibited and Restricted Chemical List PROHIBITED AND RESTRICTED CHEMICAL LIST Introduction After incidents of laboratory chemical contamination at several schools, DCPS, The American Association for the Advancement of Science (AAAS) and DC Fire and Emergency Management Services developed an aggressive program for chemical control to eliminate student and staff exposure to potential hazardous chemicals. Based upon this program, all principals are required to conduct a complete yearly inventory of all chemicals located at each school building to identify for the removal and disposal of any prohibited/banned chemicals. Prohibited chemicals are those that pose an inherent, immediate, and potentially life- threatening risk, injury, or impairment due to toxicity or other chemical properties to students, staff, or other occupants of the school. These chemicals are prohibited from use and/or storage at the school, and the school is prohibited from purchasing or accepting donations of such chemicals. Restricted chemicals are chemicals that are restricted by use and/or quantities. If restricted chemicals are present at the school, each storage location must be addressed in the school's written emergency plan. Also, plan maps must clearly denote the storage locations of these chemicals. Restricted chemicals—demonstration use only are a subclass in the Restricted chemicals list that are limited to instructor demonstration. Students may not participate in handling or preparation of restricted chemicals as part of a demonstration. If Restricted chemicals—demonstration use only are present at the school, each storage location must be addressed in the school's written emergency plan. Section 7: Appendices – October 2009 37 School Emergency Response Plan and Management Guide Prohibited and Restricted Chemical List Following is a table of chemicals that are Prohibited—banned, Restricted—academic curriculum use, and Restricted—demonstration use only.
