  • Chemical Storage Cabinets
    Storage cabinets Incompatible chemicals must be kept separately to reduce the risk of mixing in case of accidental breakage or response to an emergency within the laboratory. (A starting point is to check the Safety Data Sheet for hazard and storage requirements.) Containers must be kept tightly closed and stored in cabinets which are suitable for the chemical. It is important to check materials which have a shelf life and safely dispose of before the date expires, and generally check the label to ensure it is still suitable and provides the necessary safety information. The condition of the cabinets needs to be checked to ensure that they are providing adequate containment of the materials being stored. Ensure spill trays are used which are capable of holding 110% volume of the largest container being stored in the tray. There may be occasions where the quantities being stored are very small and secondary containment of the chemicals within a cabinet provided would be deemed as providing adequate separation. The table below provides guidance on the type of materials being stored and the type of cabinet which is suitable for that material. This is not a definitive list and does not include ‘Highly Toxic’ materials. Separate guidance is in development.

Migliaccio, Brian Boman and Gary A. Clark2 Introduction Irrigation systems can become partially or completely clogged from biological growths of bacteria or algae which are often present in surface water and ground water. Bacteria and algae use chemical elements such as nitrogen, phosphorus, sulfur, or iron as nutrient sources to grow and develop (Figures 1 and 2) (Pitts et al., 2003). Thus, irrigation systems that also receive nutrients (such as natural background concentrations in the water or from fertigation) may experience greater rates of clogging. While all irrigation systems should have some Figure 1.

  • On the Protective Effect of Omega-3 Against Propionic Acid-Induced Neurotoxicity in Rat Pups Afaf K El-Ansary*, Sooad K Al-Daihan and Amina R El-Gezeery
    El-Ansary et al. Lipids in Health and Disease 2011, 10:142 http://www.lipidworld.com/content/10/1/142 RESEARCH Open Access On the protective effect of omega-3 against propionic acid-induced neurotoxicity in rat pups Afaf K El-Ansary*, Sooad K Al-Daihan and Amina R El-Gezeery Abstract Backgrounds: The investigation of the environmental contribution for developmental neurotoxicity is very important. Many environmental chemical exposures are now thought to contribute to the development of neurological disorders, especially in children. Results from animal studies may guide investigations of human populations toward identifying environmental contaminants and drugs that produce or protect from neurotoxicity and may help in the treatment of neurodevelopmental disorders. Objective: To study the protective effects of omega-3 polyunsaturated fatty acid on brain intoxication induced by propionic acid (PPA) in rats. Methods: 24 young male Western Albino rats were enrolled in the present study. They were grouped into three equal groups; oral buffered PPA-treated group given a nuerotoxic dose of 250 mg/Kg body weight/day for 3 days; omega-3 - protected group given a dose of 100 mg/kg body weight/day omega-3 orally daily for 5 days followed by PPA for 3 days, and a third group as control given only phosphate buffered saline. Tumor necrosis factor-a, caspase-3, interlukin-6, gamma amino-buteric acid (GABA), serotonin, dopamine and phospholipids were then assayed in the rats brain’s tissue of different groups. Results: The obtained data showed that PPA caused multiple signs of brain toxicity as measured by depletion of gamaaminobyteric acid (GABA), serotonin (5HT) and dopamine (DA) as three important neurotransmitters that reflect brain function.

  • July 2014 1/15 ASSESSMENT of the PERFORMANCE
    July 2014 ASSESSMENT OF THE PERFORMANCE CHARACTERISTICS OF PROPOSED IN VITRO MEMBRANE BARRIER TEST METHOD FOR SKIN CORROSION This document contains Performance Standards (PS) for determining the validation status (reliability and relevance) of similar and modified skin corrosion test methods that are structurally and mechanistically similar to the in vitro membrane barrier test method in OECD Test Guideline 435 (1), in accordance with the principles of Guidance Document No. 34 (3). These PS include a list of 40 Reference Chemicals by which to evaluate assay performance, the essential test method components by which to evaluate the structural, mechanistic and procedural similarity of a new proposed test method, and the minimum reliability and accuracy values necessary for the test method to be considered comparable to the validated reference method (VRM). INTRODUCTION 1. Test methods proposed for use under this Test Guideline should be evaluated to determine their Field Code Changed reliability and accuracy using substances of known corrosivity and non-corrosivity. When evaluated using the recommended reference chemicals (Table 1), the proposed test methods should have reliability and accuracy that are comparable to that of the validated reference test method (VRM) (2)(Table 2). The reliability and accuracy standards that should be achieved are provided in paragraphs 3 and 4. Non- corrosive and corrosive substances, ranging from strong to weak and representing relevant chemical classes are included so that the reliability and accuracy, i.e., sensitivity, specificity, false negative rates, and false positive rates, of the proposed test method can be compared to that of the validated reference test method (2)(3).

  • Guidelines for Using Perchloric Acid
    Guidelines for Using Perchloric Acid Perchloric acid (HClO4) is a strong mineral acid. Under some circumstances it may act as an oxidizer and/or present an explosion hazards. These guidelines present information on how to handle and store perchloric acid safely. Please notify EH&S at 8-8182 if you are using perchloric acid in your laboratory. Using Perchloric Acid (< 72%) at Room Temperature At room temperature, perchloric acid up to concentrations of 72% has properties similar to other strong mineral acids. It is a highly corrosive substance and causes severe burns on contact with the eyes, skin, and mucous membranes. When used under these conditions, perchloric acid reacts as a strong non-oxidizing acid. The following precautions should be taken when using perchloric acid under these conditions: · Substitute with less hazardous chemicals when appropriate. Use dilute solutions (< 60%) whenever possible. · Conduct operations involving cold perchloric acid in a properly functioning chemical fume hood with current EH&S certification. If operations are conducted frequently or in large quantities contact EH&S to determine if a specially designed fume hood dedicated to perchloric acid use is required. · Always use impact-resistant chemical goggles, a face shield, neoprene gloves, and a rubber apron when handling perchloric acid. · When using or storing even dilute perchloric acid solutions avoid contact with strong dehydrating agents (concentrated sulfuric acid, anhydrous phosphorous pentoxide, etc.). These chemicals may concentrate the perchloric acid and make it unstable. · Always transfer perchloric acid over a sink or other suitable containment in order to catch any spills and afford a ready means of cleanup and disposal.
