Quand et comment avoir recours à un double protecteur auditif ?

Réponse de l'INRS à la question suivante :
À partir de quel niveau de bruit d'exposition peut-on conseiller le port d'un double protecteur auditif ?
Comment peut-on estimer l'efficacité d'une double protection ? Comment en déduire le niveau de bruit résiduel sous le protecteur pour le comparer aux valeurs limites d'exposition ? A. Kusy

Evaluation of safety nets by experiment-RR835

Safety nets have become a common means of providing collective protection, particularly in construction, to mitigate the effects of falls where it is impractical to use temporary edge protection. The reason for carrying out the research was to explore issues where there was doubt/concern about the performance of safety nets and their attachments. This research evaluated the effectiveness of safety nets, as used in the UK, to identify the risk (if any) of premature failure, in less than ideal conditions that could occur in the use. A series of non-ideal loading conditions involving a range of variables were conducted.

These included: net type; different impact locations (ie edge and corner); attachment point spacing; repeated dynamic loading at one position in the net; multiple falls; effect of sag in the net and industry practice to control sag; presence of defects; effect of differently shaped objects falling into net; and effects of aging and degradation from ongoing service damage and the effectiveness of test meshes in monitoring degradation.

The UK safety net industry supported the research by providing nets. Source : http://www.hse.gov.uk/research/rrpdf/rr835.pdf

 

OSHA to help prevent injuries and deaths among residential construction workers

The Occupational Safety and Health Administration has issued guidance on Fall Protection in Residential Construction to help employers prevent fall-related injuries and deaths among residential construction workers. Data shows that falls are the leading cause of death for workers involved in residential construction. Directed primarily to those working on new construction, the document describes safety methods employers can implement during stages of construction. Methods for preventing fall-related injuries and deaths include using anchors for personal fall arrest systems and fall restraints, safety net systems, guardrails, ladders, and scaffolds for activities such as installing roof sheathing, weatherproofing a roof, and installing walls and subfloors, among others.

Protection contre les chutes de hauteur : avis du 14 avril 2011 du ministère du travail relatif à une interdiction de mise sur le marché d’un dispositif antichute

Cet avis reprend la décision de la Commission européenne selon laquelle la mesure d'interdiction de mise sur le marché du modèle antichute HACA (EN 353-1) prise par les autorités britanniques est justifiée.

Ministère du Travail, de l'Emploi et de la santé. Avis aux importateurs, distributeurs, installateurs et utilisateurs d'équipements de protection individuelle contre les chutes de hauteur : antichutes mobiles incluant un support d'assurage rigide.
