SAFETYFLASH March2012.Pdf DOES YOUR SCHOOL’S CHEMISTRY LAB HAVE AN ACCIDENT WAITING TO HAPPEN? A UCLA chemistry professor has been charged in the death of a research assistant in an accident in a UCLA chemistry lab in 2008. His arraignment is set for April 11th. If convicted, the professor could go to prison for 4 ½ years. The Regents face a fine of $1.5M for each of the 3 counts of “willfully violating occupational health and safety standards”. CAL OSHA has already fined the school nearly $32,000. CAL OSHA stated that the assistant lacked proper training; that she was neither experienced nor well trained to handle the chemicals that killed her. They further stated that the professor failed to make mandatory the use of PPE; the assistant was not wearing a lab coat. The charges are believed to be the first arising from an academic lab accident in the US. The report also stated that UCLA failed to address previous safety lapses, and had ”wholly neglected its legal obligations”. The chancellor for legal affairs stated the assistant was well trained and experienced and had performed the experiment safely before, and chose not to wear protective gear. Think about that statement for a moment--- at 23 years of age, how “well- trained and experienced” could she have been? The research assistant was transferring about 1.8 ounces of t- butyl lithium from one sealed container to another when the plastic syringe came apart in her hands, spewing the chemical compound that ignites when exposed to the air. She was wearing a synthetic sweater that caught fire and melted onto her skin. She died 18 days later. A brief internet search showed surprising results for the number and types of academic laboratory accidents that have occurred within the last few years. Here are a few examples: • September 2011: University of Maryland: A small explosion in a chemistry lab sent 2 students to the hospital after the experiment blew up, causing a fire in the fume hood. The students received first degree burns and lacerations. They were using nitric acid and sulfuric acid. It was assumed during the investigation that followed that there was an incompatible substance in the waste container that reacted with the acids. • November 2011: Southwest Community College, Memphis: An explosion sent 3 students and their professor to the hospital. The explosion was caused by mixing the chemicals phosphoric acid and 2- methyl- cyclohexanol. They all suffered burns and severe cuts. There were 12 students in the lab at the time. • January 2010: Texas Tech: A graduate student worker was injured in an explosion. She lost 3 fingers and suffered serious eye damage while working with a potentially explosive chemical compound. This experiment using energized materials was being conducted under a funding agreement with the Department of Homeland Security. The student had set out to produce 1o grams of an explosive compound which was 100 times more than an informal lab limit. The student crushed a shock- sensitive material in a mortar and pestle! The experiments for Homeland Security did not come with any safety training guidelines. • June 2011: Boston College: A chemistry student was injured when her experiment exploded. She received cuts to her face and burns to her hands. She compounded the problem when she went home to clean up. HazMat crews then had to decontaminate her car and her apartment. The chemical she was using- thionyl chloride- can be used to make mustard gas and nerve toxins. She was working alone in the lab, because there were no specific guidelines that prohibited this activity. • University of Missouri: Four students were badly injured in a hydrogen explosion. • October 2011: University of Florida: A student was injured after an explosion and chemical spill. He suffered cuts to his face and hands. Another student in the lab suffered hearing loss after the explosion. • 2009: Genoa, Ill: Several students sitting in the front row in a classroom were severely injured when an experiment on the teacher’s desk blew up sending an alcohol- fueled fireball into the classroom. One student had burns over 50% of her body- and her jeans melted to her skin. One boy had the skin on his face peel off. • 2007: Michigan: At two high schools 40 miles apart 2 experiments using methyl alcohol caused fires in the labs causing severe burns. One student has undergone 8 skin grafts. Methyl alcohol experiments have caused fires in schools in California, Texas, Wisconsin and Washington State. An Associated Press article referring a Drake University Study showed that as many as 55-65% of North Carolina chemistry teachers have never been trained in safety. A USA TODAY article stated that there have been similar accidents and even death at 120 school labs in the past 10 years. The Department of Homeland Security has a $3.5 M project to study explosives detection at 12 universities. The project came with no safety-related requirements. James Kaufman with the Laboratory Safety Institute stated that lab accidents at schools and colleges happen 10-50 times more frequently than in the chemical Industry. How would your School/ College Labs measure up? Are there safety procedures in place? Has everyone been trained and tested on the safety procedures? How about chemical storage? Are incompatible items stored together? Are they stored alphabetically? Do you allow students/ research assistants to ignore safety Personal Protective Equipment rules? Are students/ assistants observed and supervised? THIS IS YOUR WAKE-UP CALL! .

RECCOMENDATIONS 1.1 The Scientific Advisory Board (SAB) has considered isotopically labelled scheduled chemicals and stereoisomers of scheduled compounds relating to the Convention according to the Director-General’s requests (see Appendixes 1 and 2). 1.2 Recommendation 1. The SAB recommends that the molecular parent structure of a chemical should determine whether it is covered by a schedule entry. This is because: (a) it is inappropriate to rely solely upon Chemical Abstracts Service (CAS) numbers to define chemicals covered by the schedules. Although relevant as aids to declaration and verification, CAS numbers should not be used as the means to identify a chemical, or to determine whether a chemical is included in, or excluded from, a schedule; (b) thus, if a chemical is included within a schedule, then all possible isotopically-labelled forms and stereoisomers of that chemical should be included, irrespective of whether or not they have been assigned a CAS number or have CAS numbers different to those shown in the Annex on Chemicals to the Convention. The isotopically labelled compound or stereoisomer related to the parent chemical specified in the schedule should be interpreted as belonging to the same schedule; and (c) this advice is consistent with previous SAB views on this topic.1 1.3 Recommendation 2.

  • 4. Chemical and Physical Information
    SULFUR MUSTARD 119 4. CHEMICAL AND PHYSICAL INFORMATION 4.1 CHEMICAL IDENTITY Information regarding the chemical identity of sulfur mustard is located in Table 4-1. Sulfur mustard has several synonyms; the most common are “mustard gas”, “H”, and “HD”. The term “mustard gas” may be used interchangeably to identify “sulfur mustard.” “H” refers to undistilled or raw sulfur mustard, which contains a large fraction of impurities (see Table 4-2). “HD” refers to a distilled or purified form of sulfur mustard (see Table 4-3). “HT” is often called sulfur mustard even though it is a mixture of 60% “HD”, <40% Agent T (bis[2-(2-chloroethylthio)ethyl]ether, CAS# 63918-89-8), and a variety of sulfur contaminants and impurities. Most studies on sulfur mustard are based on its distilled or purified form, “HD” (Munro et al. 1999). Other mustard agents, such as “HN” or nitrogen mustard (i.e., bis(2-chloro­ ethyl)methylamine hydrochloride; CAS No. 55-86-7) and lewisite (i.e., 2-chlorovinyldichloroarsine; CAS No. 541-25-3) are related to sulfur mustard. Information about “HN”, “HT”, and lewisite are not included in this document. 4.2 PHYSICAL AND CHEMICAL PROPERTIES Information regarding the physical and chemical properties of sulfur mustard (HD) is located in Table 4-4. Weapons-grade sulfur mustard can contain stabilizers, starting materials, or by-products formed during manufacturing, and products formed from slow reactions during storage (Munro et al. 1999). The typical compositions of HD and H are illustrated in Tables 4-3 and 4-4, respectively (NRC 1999; Rosenblatt et al.

  • Sulfur Mustard 21
    SULFUR MUSTARD 21 3. HEALTH EFFECTS 3.1 INTRODUCTION The primary purpose of this chapter is to provide public health officials, physicians, toxicologists, and other interested individuals and groups with an overall perspective on the toxicology of sulfur mustard. It contains descriptions and evaluations of toxicological studies and epidemiological investigations and provides conclusions, where possible, on the relevance of toxicity and toxicokinetic data to public health. A glossary and list of acronyms, abbreviations, and symbols can be found at the end of this profile. Sulfur mustard [bis(2-chloroethyl)sulfide; C4H8Cl2S; CASRN: 505-60-2] or as it is commonly called, ‘mustard gas’, is one of a class of vesicant chemical warfare agents with the ability to form vesicles or blisters on exposed skin. Sulfur mustard is a component of the H-series blister agents including undistilled sulfur mustard (H; sulfur mustard with 20–30% impurities, also known as Levinstein mustard), distilled sulfur mustard (HD or HS; approximately 96% pure), a mustard-lewisite mixture (HL), an HD/agent T mixture (HT; a mixture of HD and nonvolatile agent T), and an HD/agent Q mixture (HQ; a mixture of HD and nonvolatile agent Q; agent Q is also known as sesqui-mustard) (Gates and Moore 1946). Mustard agents, including sulfur mustard, are regulated under the Chemical Weapons Convention (CWC) (USCWCR1999). Three classes of chemicals are monitored under the CWC (1993), with sulfur mustard grouped in the highest risk class, "Schedule 1." Information about mustard agents other than sulfur mustard, such as nitrogen mustards, thickened mustard, or the mixtures listed above are not discussed in this document.

  • Evolution of Nitrogen-Based Alkylating Anticancer Agents
    processes Review Evolution of Nitrogen-Based Alkylating Anticancer Agents Fredrik Lehmann 1,* and Johan Wennerberg 2 1 Oncopeptides AB, Västra Trädgårdsgatan 15, SE-111 53 Stockholm, Sweden 2 Red Glead Discovery AB, Scheeletorget 1, 223 63 Lund, Sweden; [email protected] * Correspondence: [email protected]; Tel.: +46-(0)861-520-40 Abstract: Despite the significant progress in anticancer drug development over recent years, there is a vital need for newer agents with unique, but still effective, mechanisms of action in order to treat the disease, particularly the highly aggressive and drug-resistant types. Alkylating agents, in particular nitrogen-based alkylators, are commonly used to treat hematological and solid malignancies; they exert their antineoplastic effects at all phases of the cell cycle and prevent reproduction of tumor cells. Certain alkylating agents have been designed to be more lipophilic, enabling the compound to penetrate the cell and enhance its alkylating activity against tumors. This review details the evolution of currently available alkylating agents and their profiles, with a focus on nitrogen-based alkylating agents, as important anticancer therapy strategies.
