Many small and medium sized enterprises (SMEs) are obliged to adopt a Safety Managements System (SMS) by the Directive 2012/18/EU for the control of Major Accident Hazards (Seveso III). The difficulties of implementing an SMS within a small sized work organization are well known by practitioners, including inspectors and auditors and have been discussed in many recent papers. In the present paper is discussed a new method, based on the bowtie model, to build an easy and effective SMS. The very core of this method is a “safety net model”, which is able to connect in a network all the tangible and intangible elements of safety, including equipment, operating instructions, procedures and safety documents. This safety model has been used as the core of a smart application, the strength of which is the workers' contribution. The application allows the users to build step by step an SMS. It starts from a first version based just on regulations and standard codes (version 0), then it integrates internal knowledge through the bowtie paradigm (version 1). Near misses' discussion is used to transfer actual workers' experience into the system, to get intermediate improvement of the SMS (version 1.x). At the end audit may be used to a major release of the SMS (version 2). The full cycle has been tested at two small Seveso establishments: a galvanic plant and small glue manufacturer. 相似文献
Hydrocarbon leaks on offshore installations may result in severe consequences to personnel, to the environment and to assets. In order to prevent such leaks, it is crucial to understand their root causes. The objective of this paper is to study the circumstances of hydrocarbon leaks on the Norwegian continental shelf (NCS). In the study, all reported hydrocarbon leaks from process inventories on all offshore installations on the NCS, with an initial leak rate higher than 0.1 kg/s in the period 2008–2014, have been considered. This includes 78 hydrocarbon leaks, of which about 60% have occurred during manual intervention on normally pressurized systems. The dominating activity when leaks occur is preventive maintenance. A significant fraction of the leaks occur during the preparation for maintenance; such a preparation is typically carried out during the night shift. About half of the leaks are associated with wellhead area and manifolds, separation and compression systems. A substantial fraction of the leaks can be associated with verification faults, dominated by the failure to comply with procedural requirements that are needed to carry out independent verification. 相似文献
Waste water pollution of industrial areas can answer for the serious consequences of one of the most important environmental
threats to the future. In this study, inductively coupled plasma-atomic emission spectrometry method (ICP-AES) is proposed
to determine heavy metals (Pb, Cu, Cd, Cr, Zn, Al, Fe, Ni, Co, Mn) and major elements (Ca, Mg) in waste water of Kocabas Stream.
The concentration of metals in the waste water samples taken from 9 different stations (St.) in Biga-Kocabas Stream in November
2004 (autumn period) were determined after simple pretreatment of samples by the proposed ICP-AES method. An analysis of a
given sample is completed in about 15 min for ICP-AES the method. The results of heavy metals concentrations in waste water
were found between 0.00001–77.69610 mg l−1 by the ICP-AES technique. The concentrations of Pb, Cd, Cu, Zn, Cr, Al, Fe, Mn, Ni, Co, Mg and Ca 0.00001 (St.3,6,7) – 0.0087
mg l−1 (St.9), 0.00001 (St.4-7) – 0.0020 mg l−1 (St.8), 0.00001 (St.1,3-7,9) – 0.0041 mg l−1 (St.2), 0.0620 (St.2) – 0.2080 mg l−1 (St.3), 0.0082 (St.6) – 0.2290 mg l−1 (St.8), 0.3580 (St.2) – 1.7400 mg l−1 (St.3), 0.2240 (St.1) – 0.6790 mg l−1 (St.3), 0.0080 (St.1) – 1.5840 mg l−1 (St.3), 0.0170 (St.3) – 0.0640 mg l−1 (St.2), 0.0010 (St.1,4,5,8) – 0.0080 mg l−1 (St.3), 5.0640 (St.9) – 5.2140 mg l−1 (St.1) and 43.3600 (St.2) – 77.6961 mg l−1 (St.9), respectively. Also we measured environmental physicochemical parameters such as temperature, salinity, specific conductivity,
total dissolved solid (TDS), pH, oxidation and reduction potential (ORP), and dissolved oxygen (DO) in the waste water at
sampling stations. 相似文献
Rain water samples were collected to study the chemical composition of wet atmospheric precipitation (first event) over the
Lucknow city in the northern Indo-gangetic alluvial plains. The samples were collected in the month of July, 2005 from different
sites. The wet precipitation samples were analyzed for pH, EC, major ions (, Cl−, , , , F−, Na+, K+, Ca2+, Mg2+, ) and heavy metals (As, Cd, Al, Co, Cr, Cu, Fe, Mn, Mo, Ni, Hg, Pb, Se, Sn, Ti, V, Zn). The pH values of wet precipitation
samples ranged between 6.5 and 8.7. The analysis of linear regression applied to the set of studied variables and computation
of neutralization factors showed that neutralization occurred in precipitation samples and Ca2+ had the maximum neutralization capacity. It was found that Cl−, , Ca2+, Mg2+, Na+ and K+ in the precipitation samples originated mainly from crustal/anthropogenic sources in the region. On an average Fe, and Al
accounted for >72% of the total concentration of trace metals in the wet precipitation samples followed by Zn (>10%). Enrichment
factors calculated for heavy metals over reference background level in seawater and Earth’s crust showed relatively higher
enrichment of Zn. The principal component analysis (PCA) identified the possible sources of ionic species and heavy metals
in the wet precipitation samples. 相似文献
How do organisational cultures influence safety? To answer this question requires a strategy for investigating organisational culture. By far the most widely used research strategy is the perception survey. An alternative is for researchers is to immerse themselves in one or more organisations, making detailed observations about activities and drawing inferences about the nature of the organisation’s culture (the ethnographic method). A third technique makes use of the wealth of material that is assembled by inquiries into major accidents. This paper describes how this material can be used to provide insights into organisational cultures. It draws on specific examples from the author’s own work as well as the cultural analysis carried out by the Columbia Accident Investigation Board. It concludes with some additional suggestions for carrying out research on safety-relevant aspects of organisational culture. 相似文献
Instead of legislating after the Bhopal accident, Canada choose to innovate by adopting a consultative approach. In 1987, Environment Canada set up the Major Industrial Accidents Council of Canada (MIACC), a non profit organization financed by the federal and provincial governments and industry.
MIACC was a process rather than a structure. Governments, industries, responders, trade unions, NGOs, etc. have shared their expertise. It has worked as a partnership for the development of standards, guidance documents, etc. in prevention, preparedness, response and recovery.
MIACC ceased to exist in 1999. Although, MIACC disappearance is unfortunate, it is not dramatic. A culture of partnership, of working together towards common objectives, is now well in place and influences the development of regulations.
Natural disasters and the 911 terrorist attack on New York triggered the publication of regulations.
The legislative process started in 2001 with the Province of Quebec adopting a new Civil Protection Act for the protection of persons and property against disasters.
Year 2003 saw major developments in the regulation of emergencies—changes that are likely to have significant influences on how companies operate in Canada. Surprisingly, however, these changes have received little attention in the media, and many companies may not be aware of their implications.
This paper will review these developments, and will examine what has already taken place. Topics include:
• The federal regulation of environmental emergencies under the Canadian Environmental Protection Act;
• Extension of the Criminal Code of Canada to allow criminal charges and possibly heavy penalties for senior officials and corporations, including an explicit legal duty to protect workers from harm;
• Quebec Civil Protection Act designed to identify and manage risks;
• Ontario‘s stepwise regulation of municipal emergency preparedness with the intended goal of NFPA 1600 compliance by 2007, and the implications for the process industries;
• Potential regulation at the municipal level.

When a major hazard occurs on an installation, evacuation, escape, and rescue (EER) operations play a vital role in safeguarding the lives of personnel. There have been several major offshore accidents where most of the crew has been killed during EER operations. The major hazards and EER operations can be divided into three categories; depending on the hazard, time pressure and the risk influencing factors (RIFs). The RIFs are categorized into human elements, the installation and hazards. A step by step evacuation sequence is illustrated. The escape and evacuation sequence from the Deepwater Horizon offshore drilling platform is reviewed based on testimonies from the survivors. Although no casualties were reported as a result of the EER operations from the Deepwater Horizon, the number of survivors offers a limited insight into the level of success of the EER operations. Several technical and non-technical improvements are suggested to improve EER operations. There is need for a comprehensive analysis of the systems used for the rescue of personnel at sea, life rafts and lifeboats in the Gulf of Mexico. 相似文献
