  • Chemicals used for pH Adjustment

    The most commonly used neutralization chemicals for acid or base neutralization are 98% Sulfuric acid and 50% Sodium hydroxide. In many cases these are very good choices, however, there are many considerations when selecting chemicals and these may not always be the best selection. The selection of the chemicals used for the neutralization of an acid or base is almost as important as the design ...

  • Counting the costs of chemical incidents

    The consequences of a lack of control when using chemical substances in the workplace are well known and apparent.  Any health and safety expert can tell you of at least one major accident whereby poor chemical management policies and procedures have lead to disaster.  Examples include Bhopal, Grangemouth, Flixborough, Seveso and more recently, Buncefield.  Major accidents like ...

  • Parting the chemical curtain with GreenWERCS

    In May, with very little fanfare, Walmart introduced an extraordinary new tool known as GreenWERCS. GreenWERCS assesses the composition of chemical intensive products -- which is just about any non-food item on a Walmart shelf that you can pour, squeeze, dab or otherwise apply to your body or use in or around your home or car. GreenWERCS analyzes the composition of individual products from ...

  • Hazard material information management and regulatory compliance

    Prior to the 1970s, legislative acts addressing hazardous chemicals were few in number and specific to a handful of topics. The Refuse Act of 1899 was often ignored and rarely enforced, and the Atomic Energy Act of 1954 was exclusive to radioactive material. When it came to workplace and community safety involving the handling, storage, disposal, and transportation of hazardous materials, ...

  • The role of persistence in chemical evaluations

    The initial stage in the assessment and priority‐setting of chemicals for their potential to cause harm to humans and the environment is usually a hazard assessment employing metrics for persistence, bioaccumulation and inherent toxicity. This hazard assessment is followed, when necessary, by the more demanding task of risk assessment. Hazard assessment of data and processes influencing ...

  • Cost Justification of EH&S Information Systems

    Background While there has been significant progress in developing accounting methods that integrate environmental considerations into the decision making process, conventional accounting practices generally lean toward the near side of complexity. Many organizations do not include the cost of activities such as EH&S monitoring as cost to production, but rather tend to bury these costs into ...

  • Carcinogens are Cancer Causing Chemicals

    What’s at Stake? A carcinogen is any substance that can cause cancer. They are chronic toxins that cause damage after repeated or long-term exposure. For some people, the workplace can be a source of exposure to some carcinogens, such as asbestos, benzene, or formaldehyde. What’s the Danger? Benzene is a colorless, flammable liquid with a sweet ...

  • Estimating hazardous concentrations by an informative bayesian approach

    The species sensitivity distribution (SSD) approach is recommended for assessing chemical risk. In practice, however, it can be used only for the few substances for which large‐scale ecotoxicological results are available. Indeed, the statistical frequentist approaches used for building SSDs and for deriving hazardous concentrations (HC5) inherently require extensive data to guarantee ...
