CIS 07-1447 Practical assistance for the preparation of an explosion protection document
Praxishilfen zur Erstellung des Explosionsschutzdokumentes [in German]
Guide pratique pour l'élaboration du document relatif à la protection contre les explosions [in French]
European Directive 94/9/EC, known as the ATEX Directive (see CIS 95-27), specifies the requirements concerning the protection against explosions within enterprises. It requires employers to carry out a hazard evaluation and to record the findings in an explosion protection document, together with all related prevention measures. This booklet presents the structure and content of this document, and provides several examples of hazard evaluations (floor over a silo complex, pneumatic conveying systems, storage of explosive gases and liquids, paint spraying booths, etc.).

Exploratory study of heavy truck tyre blowout and explosion phenomena
Etude exploratoire sur les phénomènes d'éclatement et d'explosion de pneus de camions lourds [in French]
In Quebec in the last four years, three fatal accidents involving heavy vehicles were directly attributable to the bursting of tyres. The degradation of the rubber under the effect of heat is the main cause. However, there are few apparent warning signs for detecting the beginning or the extent of the degradation with or without pyrolysis. This study provides updated information on the tyre bursting phenomenon, as well as its causes, consequences, risks and means of prevention. It involved a literature survey and an analysis of accident investigation reports. Previous studies dealing with means of degradation and aging of tyres, and the mechanical properties and failures of the wheel-tyre system were also updated.

Pyrotechnics: Hazard evaluation
Pyrotechnie: une évaluation des risques [in French]
Several serious accidents have occurred in recent years in Europe and around the world during the storage and use of pyrotechnic products for entertainment or industrial use. The generalized use of airbags in automobiles has considerably increased the consumption of pyrotechnic products in industry, making it even more necessary to manage the hazards during their storage or handling. This article reviews the current regulatory situation in France in this field.

Simplified methodology for chemical risk assessment: A decision-making tool
Méthodologie d'évaluation simplifiée du risque chimique: un outil d'aide à la décision [in French]
Worker's protection is above all based on assessing the risks and introducing an appropriate prevention policy. Concerning chemical risks, this assessment is often difficult on account of the wide diversity of products and formulations used. To help enterprises faced with this problem, INRS, in collaboration with the French National Prevention and Protection Centre (CNPP), has developed a simplified method to assess the health, safety and environmental risks of chemicals that can be used by managers of small enterprises. The risk prevention departments of a number of enterprises in various sectors have applied this method, and the results obtained concur with the views of experts.

Flammability of gas mixtures Part 2: Influence of inert gases
Systems containing flammable gas, inert gas and air were studied to evaluate the ISO 10156 method for calculating the flammability of gas mixtures. The fire potential of flammable gases was the focal point of a separate article (see CIS 05-681), while this article discusses the influence of inert gases on the flammability of gas mixtures. The estimated results given by ISO 10156 were compared with measurements based on the German standard DIN 51649-1. The comparison shows that ISO 10156 supplies conservative values, which can be regarded as safe in all cases. However, in a number of cases, ISO underestimates the inerting capacity so that non-flammable gas mixtures are considered to be flammable.

Dust explosion hazard of pulverized fuel carry-over
The results of experiments carried out to examine the explosibility of the waste products (fly ash and bottom ash) from pulverized fuels (coal and petroleum coke) are presented. Tests were conducted for the fly and bottom ashes alone and also for selected fly ashes blended with the fuels. The explosion parameters of interest were explosion pressure and rate of pressure rise. The fly ashes showed no propensity to explode, whereas one of the bottom ashes did show limited explosibility. Both findings can be explained with reference to the volatile matter content of the ashes. Admixture of either coal or petroleum coke with fly ash resulted in explosible mixtures at volatile contents in the range of 7-13%, with the value being dependent on the composition of the mixture components and their particle sizes.

Development of new high-performance absorbing materials for the attenuation of low-frequency noise
Développement de nouveaux matériaux absorbants à hautes performances acoustiques pour diminuer le bruit en basses fréquences [in French]
Conventional acoustic materials used for controlling noise in occupational settings are mainly effective for medium and high frequencies. In an earlier study (Etudes et Recherches R-278, http://www.irsst.qc.ca/files/documents/PubIRSST/R-278.pdf), the Occupational Safety and Health Institute of the Canadian Province of Quebec (Institut de recherche en santé et en sécurité du travail - IRSST) evaluated the possibilities presented by heterogeneous porous materials that are more effective in absorbing lower frequencies. This document reports on the further modelling and optimisation of these materials during laboratory testing. Work on the project is expected to continue, with the next phases involving additional numerical and experimental studies in areas including the building, aeronautical and automobile industries.

CIS 04-189 Specification for electrical apparatus for explosive gas atmospheres - Part 10: Classification of hazardous areas
This standard concerns the classification of hazardous areas and provides a proper selection and installation of apparatus for use in hazardous areas where the risks of flammable gases may arise, in order to allow the selection and installation of appropriate equipment in such areas. It is intended to be applied where there may be a risk of ignition due to the presence of flammable gas mixed with air under normal atmospheric conditions. Requirements are supplementary to those in SS 254: Part 0: 2001 which apply to the classification of hazardous areas. In areas where dangerous quantities and concentrations of flammable gas may arise, protective measures are to be applied in order to reduce the risk of explosions. This standard sets out the essential criteria against which the risk of ignition can be assessed, and gives guidance on the design and control parameters which can be used in order to reduce such a risk.

Dangerous Substances and Explosive Atmospheres Regulations 2002. Approved Code of Practice and guidance
This document provides a general Approved Code of Practice and guidance on the Dangerous Substances and Explosive Atmospheres Regulations 2002 (DSEAR) (see CIS 03-1035). DSEAR sets minimum requirements for the protection of workers from fire and explosion risks related to dangerous substances and potentially explosive atmospheres. The key requirements in DSEAR are that risks from dangerous substances are assessed and eliminated or reduced. The regulations revokes, repeals or modifies a large amount of old legislation relating to flammable substances and dusts.
