  • What makes high-risk pipelines deteriorate to a state of failure?

    According to AWWA's 2016 Benchmarking Survey, the average water and wastewater utility has seven breaks per 100 miles of piping every year. Tip-top systems experience just four breaks in that distance, while those at the bottom have 18. While it’s interesting to note the difference in break rates, it’s unfair ...

  • Read about Confined Space in Construction and Atmospheric Testing Right Here!

    In 1993, 29 CFR 1910.146 went into effect as the first federal legislation governing entry into permit-required confined spaces in general industry. Because some industries, such as the construction industry, were covered by specific Occupational Safety and Health Administration (OSHA) safety regulations, they were exempt from the confined space entry requirements of the general industry rule. ...

  • Empirical validation of a new heat stress index

    Thermal stress is a well-recognised health hazard in the workplace. In addition to the health deficits, working in the heat can impact significantly on the productivity of some industries which are located in harsh environments. A long-standing dilemma in OHS has been the specification of what constitutes a safe working environment. The current indices used to evaluate the environment are either ...

  • If you can`t stand the CO2, get out of the kitchen - part 1

    There are two potentially dangerous types of gas in a commercial kitchen: 1) the flammable ones used for cooking (e.g. methane/natural gas; propane/liquefied petroleum gas); and 2) the noxious, gaseous products of combustion such as carbon monoxide, carbon dioxide and hydrocarbons. It would be good to know how to avoid them. But a search for advice on kitchen ventilation threatens to drown the ...
