Protection des mains et des bras (RSS)
Avec l'essor prévu des nanotechnologies, les risques d'exposition aux nanoparticules, déjà présents en milieu de travail, augmenteront de façon exponentielle. La contamination par voie cutanée a fait l'objet de peu de travaux et certains croient qu'elle est sous-évaluée. Il semble aussi que, dans certains cas, des taux préoccupants de nanoparticules puissent traverser les vêtements de protection, en particulier les gants de laboratoire. L'équipe de recherche vise à élaborer une méthode...
This study developed biomechanical models for hand breakaway strength that account for not only grip force but also hand-handle frictional coupling in generation of breakaway strength. Specifically, models for predicting breakaway strength for two commonly-used handle shapes (circular and rectangular handles) and varying coefficients of friction (COF) between the hand and handle were proposed. The models predict that (i) breakaway strength increases with increasing COF and (ii) a circular handle with a 50.8mm-diameter results in greater mean breakaway strength than a handle with a rectangular cross...
En réponse à une demande formulée par deux associations sectorielles paritaires et trois milieux de travail représentants les policiers, les agents de la paix en services correctionnels et les cols bleus, l'Institut de recherche Robert-Sauvé en santé et en sécurité du travail (IRSST) a mis au point une méthode d'essai pour déterminer la résistance des gants de protection contre les piqûres causées par les aiguilles médicales. L'absence de méthodes d'essai normalisées rendait...

International Glove Association launches Certification and Standards 2010 Initiative Program will end confusion over glove standard ratings. In the hand protection marketplace there are many concerns on how confusing the different standard ratings are (CE and ANSI) as well as how they are misused and miscommunicated to the end users. There is a need for leadership from the hand protection industry on this issue. As a result, the International Glove Association (IGA) has staked out a leadership role on setting performance standards for attributes of hand protection and certifying available products...
02/28/2011 American National Standard for Hand Protection Selection Criteria (ANSI/ISEA 105-2011), first published in 2000, is designed to assist users and employers in the appropriate selection of gloves for identifiable workplace hazards that could result in chemical burns, severe cuts and lacerations, and burns caused by heat and flame exposures. ANSI/ISEA 105-2011 was developed by ISEA's Hand Protection Group and was reviewed by a consensus panel representing chemical handling professionals, testing facilities, utility providers, and government agencies. http://www.safetyequipment.org/news...
Conformity assessment is key to ensuring that the products we purchase are effective and perform to specifications; as users we are not expected to know or be engaged in the actual intricacies of how products are tested and verified to make sure that they meet performance requirements. This report focuses on conformity assessment for occupational personal protective technologies (PPT)—ensuring that PPT are effective in preventing or reducing hazardous exposures or situations that workers face in their jobs. Because respirators already have an extensive testing and conformity assessment process...
Human skin offers natural protection against external influences. This protection is unfortunately often inadequate. The human body therefore sometimes needs clothing which not only keeps it warm, but also protects it against exposure to hazardous substances. Such substances range from moisture to chemicals with a variety of properties. Chemical exposure is not always obvious, as it is in the case of an acute caustic burn; it may also begin insidiously with a skin irritation, and progress through sensitizing to severe skin damage. Even substances that are regarded subjectively as harmless, such...
L'objectif de ce nouveau site Web est de fournir l'information nécessaire afin d'aider les individus et les responsables SST à identifier des gants de protection en adéquation avec leurs besoins. Source : http://www.irsst.qc.ca/gants/fr/index.html
Previous studies of anti-vibration gloves have typically only considered the effect that a glove might have in the direction of compression of the glove material. This project investigates the performance of an anti-vibration glove taking account of the influence that the glove might have in three axes. This requires consideration of the performance of the glove material in both compression and shear. Since the adoption of the revised international standard ISO 5349-1:2001 in the UK as BS EN ISO 5349-1:2001 and the implementation of the Control of Vibration at Work Regulations 2005, the technique...
The current international standard for gloves designed to protect against mechanical injury is EN 388, which has been adopted word for word by AS/NZS 2161. However, this standard has a number of shortcomings. In particular, the performance tests are often misconstrued and often do not reflect the environment in which a glove may be used, or the glove's actual performance in all-too-common circumstances. This article briefly reviews the four performance tests covered by AS/NZS 2161 (abrasion, cut, tear and puncture) and lists a few considerations that should be made when interpreting the results...
En raison de la multiplicité de ses fonctions, la main se trouve très fréquemment en situation dangereuse. Les risques découlant de l'activité professionnelle peuvent être classés selon la nature du travail en trois catégories : - les risques mécaniques - les risques thermiques et électriques, - les risques chimiques. Bien souvent, ces risques se manifestent lors d'opérations de manipulation, de préhension, levage, transport de charges. Les causes des accidents et des maladies professionnelles de la main...
