15-year compressed air analysis at a French Navy laboratory in Toulon
Quinze années d'analyse d'air comprimé au sein du laboratoire de la Marine de Toulon [in French]
Breathing compressed air is a common practice for many professionals. Among them, French Navy personnel uses compressed air for diving and operations conducted in polluted environments (closed respiratory systems). The Navy has implemented a monitoring plan for several decades to limit chemical toxicity risks associated with compressed air usage. Laboratories offering expert surveys are a key component of this programme. This article's main aim is to present compressed air analysis results obtained over the last 15 years by the Naval expert survey and surveillance laboratory (LASEM) in Toulon. This retrospective analysis shows in particular that the overall non-compliance rate is less than 10%, excluding humidity measurements, despite the very stringent standards. Prospects for improving analytical services are proposed for guaranteeing better assessment of compressed air-related chemical risks.

Probability of Detection (PoD) curves - Derivation, applications and limitations
Despite the large amount of "Probability of Detection" (PoD) data available, it is believed that PoD curves produced from PoD data are not very well understood by many of the persons who apply them. It is consequently important to question the validity of these curves as well as their limitations. This report aims to answer such questions and in particular their relevance to fitness for service issues involving PoD. The overall goal of this project is to provide clear, concise, understandable and practical information on the use of PoD curves, particularly aimed at safety and health inspectors.

Computer model for the design and validation of directed water deluge systems for the protection of plant containing pressurised flammable materials against fire
This report describes the development of a computer model to predict the water distribution on the surface of vessels containing pressurized flammable materials protected by directed water deluge systems. The model is intended to be an integral component of new improved guidelines for the design of such water deluge systems. The aims of the project were to extend the range of applicability of an existing basic model to a wide range of tank sizes and water deluge designs. Predictions of water distributions across the surface of storage vessels obtained using the model have been validated against measured (experimental) data and a close level of agreement to within 7% has been demonstrated.

Piping systems integrity - Management review
This project was intended to develop proposals that would help companies reduce the occurrence of piping failure on industrial sites. It identified the key areas where improvements could be made. Work involved examining commonly-available information on piping, reviewing typical failures of piping and drawing upon practical experience from the chemical industry. A "life cycle" model of piping integrity was used to assess findings and make recommendations. The life cycle starts with scope definition, continues through design, construction, operation, and maintenance, includes modification and repair, and ends with decommissioning and disposal.

Hand injuries due to high-pressure injection devices for painting in shipyards: Circumstances, management and outcome in twelve patients
Injuries due to high-pressure injections are frequently underestimated occupational accidents, which may have disabling outcomes. The occupational injuries logbooks of two shipyards were examined. Twelve accidents due to the utilization of high-pressure equipment were reported. Data were obtained by reviewing the employers' logbooks and hospital records. Contaminants were epoxy paint and stucco, paint solvent, hydraulic and industrial oil. The palm was injured in three cases and the fingers in nine. In 91% of cases, the accident occurred in the last two hours of the work shift. Causes were mishandling in nine cases and rupture of the high-pressure equipment in three. Mean time to medical treatment was 42.5hr. Ten workers were permanently disabled. Prompt surgical intervention with debridement and decompression was done in two workers, who healed completely. The ten patients who were not treated immediately eventually experienced a high rate of disability and five of them also suffered amputation.

Validation of propping based on high-density polyethylene piping or on metallic profiles normally used for culverts or sewers
Validation d'un étançonnement fait d'un tuyau de polyéthylène haute densité ou de profilés métalliques normalement utilisés pour les ponceaux et les égouts [in French]
The objective of this study was to validate the use of circular cross-section metallic or high density polyethylene profiles for propping during short-duration excavation work. This type of propping is easier and quicker to install than rigid panels and are better suited to reduced-diameter boring. Work involved measurements in the laboratory and at construction sites, together with mathematical simulations on the mechanical behaviour of pipes. It was concluded that this type of shoring is well suited provided one selects pipes having a minimum specified rigidity.

Study on leakage in flat gaskets for manhole covers
Leckageuntersuchungen an Flachdichtungen für Mannlochverschlüsse [in German]
The leak-proof properties of seals depend on numerous factors, some of which are relatively complex. This report presents the results of a study on the leakage behaviour of flat static joints, and more particularly of bolted manhole cover gaskets. Three series of tests were conducted: leakage behaviour as a function of bolt tightening procedures, using different types of gaskets and with the systematic change of compressive load per unit area. Findings show that the specific rates of leakage in the nine types of flat gaskets studied are influenced considerably by the type of sealing material, the conditions of use and by the mechanical properties of the equipment flange used. The report will help users select suitable sealing.

Assessment of methods to detect leaks in the casing of room sealed appliances
Incidents involving the escape of carbon monoxide from central heating boilers occur frequently. The purpose of this study was to evaluate suitable procedures for detecting leaks from the case and seals of pressurized central heating boilers. The following procedures were found to be suited: visual and tactile inspection of the case and seals; smoke tubes to produce smoke for flow visualization; smoke matches to produce smoke for flow visualization; ordinary matches and wax tapers to produce a flame for flow visualization. However, the use of a flue gas analyser is not recommended: it does detect the drop in oxygen concentration or the presence of carbon monoxide due to a leak of combustion products, but may miss the small changes from a boiler burning well but leaking only slightly.

Report on a second study of pipeline accidents using the Health and Safety Executive's risk assessment programs MISHAP and PIPERS
HSE uses mathematical models to estimate risks when examining proposals to develop land in the vicinity of high-pressure pipelines. PIPERS and MISHAP are computer programs based on these models. An earlier version of MISHAP, called MISHAP98, was not sufficiently conservative in some respects, and it was recommended that improvements be made. These have now been implemented and the present work examines the performance of the new version, called MISHAP01 that is now the routine tool for studying natural gas pipelines. PIPERS is an extension and development version of MISHAP, embodying alternative ways of modelling releases from natural gas pipelines and having additional models for use in the study of risks in the vicinity of pipelines carrying flashing and non-flashing liquids. Over 100 reports of pipeline accidents were studied using these programmes, and recommendations are made concerning their applicability and areas for further improvement.

Simple mechanical joints for dangerous substances?
Einfache Gleitringdichtungen für gefährliche Medien? [in German]
Mechanical joints used in chemical plants, refineries or storage tanks are important components of safe operations. They are generally reliable under normal conditions. However, in cases of failure, they could result in the leakage of important quantities of liquids, which depending on their nature could have serious consequences. A team from the University of Duisburg undertook to examine what would happen if mechanical joints were damaged. A test rig was built for this purpose, including a pump for submitting the joints to extreme conditions and to determine the volumes of leaked liquids. Trials were carried out with different types of joints. Results indicate that that mechanical joints are relatively reliable and even in cases where the joint surface is damaged, leakage volumes remain low.

Investigations on industrial safety and health protection using devices working with jets of liquids on building sites in the construction industry
Untersuchungen zur Arbeitssicherheit und zum Gesundheitsschutz beim Einsatz von Flüssigkeitsstrahlern auf Baustellen im Bauhaupt- und Baunebengewerbe [in German]
High-pressure water-jet equipment is increasingly used in many sectors of the building industry. In this study, the different hazards due to these devices are analysed with the objective of identifying appropriate prevention measures. The main hazards identified include the high noise level, bruises and injuries due to the jet, the wrenching of the hose and fittings, risks of trips and falls, high recoil forces and vibrations, in particular from the hand-held parts and due to poor work postures. Preventive measures for reducing these hazards are proposed.

Standardization relating to the Pressure Equipment Directive
Normung im Bereich der Druckgeräte-Richtlinie [in German]
The purpose of this study was to develop an overview of the standards related to the European Pressure Equipment Directive 97/23/EC (see CIS 98-409). A survey of expert opinion was carried out to determine the degree with which the European standards took account of German regulations, and whether there remained further needs for standardization at the European level. Based on this overview, actions required at the German level with respect to the harmonization of standards for equipment operating under pressure were determined, and are the object of recommendations.

Survey of criticality of risk from LPG storage tanks at user-sites in North India
LPG is stored and handled in liquefied form under pressure. LPG storage systems are spreading rapidly across India. The large inventories in bottling plants and at user industries have lead to anxiety among industrial workers, the neighbouring public and government authorities. This article presents the results of a survey of the potential damage that could result from gas explosions following accidental release at a number of industrial sites in North India.

Air sampling at the chest and ear as representative of the breathing zone
Tracer gas concentrations were measured on a 60%-sized mannequin, which was holding a sulfur hexafluoride source at waist height while standing in a wind tunnel. Samplers were placed at the mannequin's mouth, in front of the ear and at three chest locations at lapel level. Simultaneous 15-min time-weighted average samples were taken with sampling pumps. Concentrations at all sampling locations when the mannequin faced to the front and side were less than a tenth of the levels measured at the nose, when the mannequin faced downstream. Different flow orientations and velocities affected the ratios of concentrations. At the back orientation, the chest sampler provided lower overestimates of measurements at higher velocities than at lower values. Results showed significant differences between concentrations at the nose and lapel. These findings should be interpreted with caution, because a dense tracer gas and an unheated not breathing mannequin were used.

An evaluation of industrial ventilation branch screening methods for obstructions in working exhaust systems
Methods in identifying obstructed branches in industrial ventilation systems are divided into two categories: pressure comparisons and pressure ratio comparisons. The first compares measured static pressures with the corresponding design static pressures or previously measured pressures. The second compares the ratios of two measured pressures. Data were collected from 6 industrial ventilation systems. Each one was tested for naturally occurring or deliberately inserted obstructions. The pressure ratio method was substantially superior for the detection of obstructions.

Best practice for risk based inspection as a part of plant integrity management
This report discusses the best practice for the application of Risk Based Inspection (RBI) for the inspection of pressure equipment and systems that are subject to the requirements for in-service examination under the Pressure Systems Safety Regulations 2000 (PSSR). It can also apply to equipment and systems containing hazardous materials that are inspected as a means to comply with the Control of Major Accident Hazards Regulations (COMAH, see CIS 00-24). The report considers the application, data requirements, team competences, inspection plan (including NDT techniques and reliability) and overall management of the RBI process. An audit tool is given in the Appendices order to assist the evaluation the RBI process. This contains a flow diagram followed by a series of questions and a commentary relating to each stage, outlining the proposed best practice.

Detection of leaks in seals of fan pressurised central heating boilers
The purpose of the project was to define a suitable method for detecting leaks of combustion products from the case and seals of fan pressurized central heating boilers, which can result in carbon monoxide emissions. Several methods were found to have the potential to detect leaks: smoke tubes to produce smoke for flow visualization; flue gas analyser to detect the drop in oxygen concentration due to a leak of combustion products or to determine the flue gas composition; micro-manometers to determine the overpressure inside the boiler casing. Further work is required to determine appropriate test criteria and to develop suitable procedures for use by a service engineer.
