  • Gas Safety in Confined Spaces

    Introduction An offshore worker ensures a vessel is safe to enter; a plant manager enters a small plant room; a contractor inspects the lining of a sewage pipe.  All these personnel face common dangers, despite working in widely different industries.  Gas-related injury poses a serious threat in any confined space where the free movement of air is limited. A confined space ...

  • Gas safety in confined spaces

    An engineer repairs buried cables; a plant manager enters a small plant room; a contractor inspects the lining of a sewage pipe.  All these personnel face a common danger, despite working in widely different industries.  Gas-related injury poses a serious threat in any confined space where the free movement of air is limited.  ...

  • Ensuring personnel safety in a confined space

    “There are no second chances with a confined space entry. It has to be right first time.“ Identifying a confined space… The HSE Confined Space Regulations 1997 define a confined space as: “A space of an enclosed nature where there is a risk of death or serious injury from hazardous substances or dangerous conditions” Some confined ...

  • 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. ...

  • Experimental Study of Suppressing PVC Fire with Water Mist using a Cone Calorimeter

    Effect of water mist on the small-scale solid fuel PVC (poly vinyl chloride) fire in a confined space has been studied experimentally using a cone calorimeter. In this study, the combustion characteristics of PVC, and the interaction between the water mists and the diffusion flame in a confined space with proper ventilation control are studied under various conditions in the cone calorimeter. The ...

  • Active emitters based on nanostructured Si

    The present paper deals with the use of Si nanoclusters as efficient sensitisers for Er and Nd rare earth ions or as active emitters in Si/SiO2 Fabry-Perot microcavities. The films have been fabricated using the reactive magnetron sputtering of a silica target. The energy transfer efficiency from Si-nc towards Er ions has been studied as a function of the fabrication parameters (hydrogen rate, ...

  • Tracer studies on an aerated lagoon

    The city of Palmerston North, New Zealand, has two aerated lagoons as its secondary treatment facility. Interest about treatment efficiency led to an investigation into the hydraulics in the second lagoon to determine if further optimisation was viable. A tracer study using rhodamine WT was undertaken to ascertain the stimulus response output. Samples were also taken at 24 points within the ...

  • Welding Fumes and the effects of Manganese

    The potential risks of welding operations include the potential to breathe in metal fumes and toxic gases. Fume particles are formed from the vaporisation of molten metal that occurs during the process. These particles are very fine in size and may join together to form larger particles.. The biggest risk is exposure to the manganese contained in fumes that are given off during welding. ...

  • The Light at the End of the Tunnel - How to Successfully Operate a UV Disinfection System

    ABSTRACTOver the past ten years, ultraviolet (UV) technology has become a commonly applied method of disinfecting of wastewater effluent. UV disinfection involves passing wastewater effluent through a confined chamber with rows of underwater lamps emitting UV energy. Viruses and bacteria become inactivated upon exposure to dosages of UV energy, thereby disinfecting the wastewater. The UV system ...

  • Pt. 2 - IN the MIX - Construction Safety and Gas Detection

    This is part 2 of our 4 part series on Gas detection in the Construction Industry. With so many OSHA regulations, where do we begin to search for help with gas detection or respiratory protection within confined spaces? To start, OSHA has a web tool called the OSHA Construction “eTool”. ...


  • Gas Monitoring for Ventilation Control and Energy Management

    The growing demand for underground and enclosed parking and maintenance garages (resulting from limitations on land availability) has increased the awareness and need for proper ventilation and control systems. In addition, increased health and safety programs have only added to the concerns of toxic and combustible gases in confined or enclosed spaces. Historically, ventilation and make-up air ...

  • Workplace Monitoring: Who, What, When, Why, How?

    In my previous articles in this series for SHP readers, I have focussed on the need for current attitudes to general health and safety processes to change and emphasised the importance of regular monitoring. The best way to combat those ‘hidden killers’ and protect our workforces is to increase awareness of the benefits of regular monitoring and detection.  Employees then need to ...
