Formation sur le harnais de sécurité pour le secteur automobile

L'association sectorielle services automobile présente le contenu d'une formation de 45 minutes sur l'achat et le port du harnais de sécurité. Développée avec la contribution de l'ASP construction, la formation comporte des conseils sur l'ajustement, l'entretien et l'inspection quotidienne et annuelle.

Are Health Care Workers Protected?

Background: The proper use of personal protective equipment (PPE) by health care workers (HCWs) is vital in preventing the spread of infection and has implications for HCW safety. Methods: An observational study was performed in 11 hospitals participating in the Canadian Nosocomial Infection Surveillance Program between January 7 and March 30, 2011. Using a standardized data collection tool, observers recorded HCWs selecting and removing PPE and performing hand hygiene on entry into the rooms of febrile respiratory illness patients. Results: The majority of HCWs put on gloves (88%, n = 390), gown (83%, n = 368), and mask (88%, n = 386). Only 37% (n = 163) were observed to have put on eye protection. Working in a pediatric unit was significantly associated with not wearing eye protection (7%), gown (70%), gloves (77%), or mask (79%). Half of the observed HCWs (54%, n = 206) removed their PPE in the correct sequence. Twenty-six percent performed hand hygiene after removing their gloves, 46% after removing their gown, and 57% after removing their mask and/or eye protection. Conclusion:
Overall adherence with appropriate PPE use in health care settings involving febrile respiratory illness patients was modest, particularly on pediatric units. Interventions to improve PPE use should be targeted toward the use of recommended precautions (eg, eye protection), HCWs working in pediatric units, the correct sequence of PPE removal, and performing hand hygiene.

Over-treating tiles with 10 times the amount of hydrofluoric acid normally used leads to more slip resistant surface

There are many anti-slip treatments that claim to reduce the risk of slips and falls. In a previous investigation, it was shown that the normal treatment of smooth and glazed ceramic tiles with an aqueous solution of hydrofluoric acid increased only slightly the dry and wet friction and the average roughness but made the tiles more fragile and more difficult to clean. This article reports the impact of multiple cycles of hydrofluoric acid treatment and abrasive wear and the impact of over-treating the tiles with 10 times the amount of hydrofluoric acid normally used. The overtreatment removes more glaze than the normal treatment and it leads to a significantly rougher and more slip resistant surface. On the other hand, the surface properties and slip resistance of the tiles exposed to multiple cycles of hydrofluoric acid treatment and abrasive wear do not evolve much.

Exposure to high temperature environments can result in the thermal degradation or melting of a Self- Contained Breathing Apparatus facepiece lens

During the investigation of firefighter fatalities that occurred from 2002 to 2011, the National Institute for Occupational Safety and Health (NIOSH) found evidence of thermal degradation of facepiece lenses that may have been a contributing factor in three fatalities. In the fatality cases, the firefighters were likely still “on air”  at the time they were overrun by extreme thermal conditions; all had their Self- Contained Breathing Apparatus (SCBA)  facepiece still in place; all had SCBA facepieces that displayed extensive damage consistent with thermal conditions that likely exceeded the capabilities of the SCBA facepiece lens, resulting in the loss of respiratory protection from an Immediately Dangerous to Life and Health (IDLH ) environment. The firefighters in these incidents suffered thermal injuries to their respiratory system and sustained inhalation injuries from products of combustion.

Ladder Use in Construction Guideline

Workers on construction sites continue to fall from ladders and become critically injured or killed. The Provincial Labour-Management Health and Safety Committee (PLMHSC) has prepared a guideline on safe ladder use in construction to assist workplace parties in understanding their obligations under the OHSA and its regulations. The Ministry of Labour views the guideline as a recommended set of industry best practices that may be used as part of an employer's health and safety program.

Les exigences actuelles ne sont pas suffisantes pour la caractérisation antistatique d'un VT ou EPI

Une étude a été menée par l'INRS, en collaboration avec l'INERIS, sur les propriétés dissipatrices des vêtements de travail (VT) et des équipements de protection individuelle (EPI). L'analyse des résultats fait ressortir que les modes opératoires et les exigences actuels ne sont pas suffisants pour la caractérisation antistatique d'un VT ou EPI dans son ensemble. La conception (coutures, poches, logos...) mais aussi la nature et l'épaisseur des couches portées sous l'équipement jouent un rôle prépondérant sur la dissipation des charges. De la même manière, l'usure et les cycles de lavage répétitifs ont un impact négatif sur les performances initiales.  L'objectif à terme est de pouvoir stabiliser une méthode et les critères associés permettant de valider l'équipement dans sa globalité pour une utilisation en zone ATEX.
