  • Safety Showers for the Fertiliser Industry

    The fertiliser industry uses extremely hazardous materials in their production processes. Common industry chemicals like anhydrous ammonia can cause burns and inhalation hazards. Others like ammonium nitrate pose a risk of fire and explosion. In 2006 a large explosion at a fertiliser plant in Teeside, UK caused a fire involving mixed gases including hydrogen, nitrogen and ammonia ...

  • Process-generated contaminants

    Overview: There is not currently a formal and universally recognised definition of a process-generated substance. Process-generated contaminants can be generated as emissions from combustion processes, abrasion and/or other processes that physically or chemically degrade or otherwise modify the starting material(s), e.g. degradation/composting of organic materials. Such ...

  • 3-MCPD and glycidol in infant formula

    SpeedExtractor E-916, MultivaporTM P-6: Extraction of 3-MCPD and glycidyl-esters from infant formula Esters of 2- and 3-MCPD (monochloropropanediol) are formed during the refining process of vegetable oils. Therefore, any food that contains vegetable oils can potentially contain 2- or 3-MCPD esters. 3-MCPD has been classified as potentially carcinogenic to humans, whereas glycidol is ...

  • 12,000 U.S. schools are within a mile of a hazardous chemical facility. What should we do about that?

    In the absence of a federal U.S. policy for schools located near potentially dangerous sites, community activists search for safer solutions. On April 17, 2013, an explosion and fire at the West Fertilizer Company plant in West, Texas, killed 15 people and injured hundreds. It also destroyed more than 150 buildings around the plant. Among these were the West Intermediate School for 4th and ...

  • MSDS vs SDS, a comparison

    The main purpose of the switch from the MSDS to the SDS is to create a simpler and more unified standard way to communicate the hazards of a chemical. Prior to the switch companies may have had MSDS in multiple formats with information on those formats in varied locations. By moving to a universal format it makes it easier for employees to find information on a chemical, it also lowers the burden ...

  • A dangerous list

    California has proposed Prop 65 Listings under the Labor Code mechanism, but using such listing methods could set a dangerous precedent. On March 4, 2011, the California Office of Environmental Health Hazard Assessment (OEHHA) proposed to list four chemicals as known to the state to cause cancer under the Safe Drinking Water and Toxic Enforcement Act (Prop 65) based on the Labor Code mechanism ...

  • A Dangerous List

    On March 4, 2011, the California Office of Environmental Health Hazard Assessment (OEHHA) proposed to list four chemicals as known to the state to cause cancer under the Safe Drinking Water and Toxic Enforcement Act (Prop 65) based on the Labor Code mechanism contained in Health and Safety Code Section 25249.8(a). The four substances are: cyclopenta[cd]pyrene, ethanol in alcoholic beverages, ...

  • The correlation of hypersensitivity for HRS/IRR and the 'inverse' dose-rate effect – its potential influence on LDR brachytherapy: a review

    The 'Inverse' Dose-Rate Effect (IDRE) has been extensively studied (Leonard, 2000; 2007a; Leonard and Lucas, 2008a?b). We here consolidate these results. We have shown a correlation between Hyper-radiosensitivity and the Induced Radioresistance effect (HRS/IRR), and IDRE has the same threshold and transition behaviours. This supports a conclusion that IDRE is the dose-rate manifestation of ...

  • Playing Dirty: Analysis of hazardous chemicals and materials in games consoles

    The use of hazardous chemicals and materials in electronic products is widespread. Despite some recent improvements – a result of a combination of legal restrictions in some parts of the world, and voluntary action by companies – many devices still contain a variety of hazardous substances. These include chemicals which fall outside current legislative controls, as highlighted in recent studies ...

  • Hazardous chemicals and proper storage solutions

    Many acceptable categorical storage schemes have been proposed and used by laboratories in academic, industrial, government and medical institutions. The common features uniting all these plans is the separation of incompatible materials. The differences in these various storage schemes arises in the number of groups that should be established for segregation purposes. The ten most commonly cited ...

  • Management of chemical exposure: the limitations of a risk-based approach

    Risk assessment and risk-based management approaches are becoming incorporated into a wide range of disciplines as frameworks for use in critical decision-making pathways. During its rapid expansion, many of the assumptions, subjective judgements and irreducible uncertainties inherent within the risk paradigm are becoming increasingly overlooked. This paper provides a critical review of the ...

  • X-Ray Radiographic Investigation of Perchloroethylene Migration at the Livingston Derailment Site

    X-ray radiography of soil cores was used as the primary test method to determine the reasons for the permeation of perchloroethylene into apparently impermeable clay layers at a hazardous chemical spill site. X-ray powder diffractometry, scanning electron microscopy, and chemical analysis were also performed to characterize the materials and structures observed in the soil cores through X ...
