Abattage manuel, 2e édition

La deuxième édition de ce guide expliquant les méthodes sécuritaires d'abattage manuel est conforme à la formation donnée aux travailleurs forestiers et on y prend en compte les modifications apportées au Règlement sur la santé et la sécurité du travail du Québec. Il comprend en outre deux nouvelles sections portant sur les règles à suivre en cas d'orage ou en présence d'un ours.

Process approach-based methodology for safe maintenance operation

From concepts to SPRIMI software prototype
Maintenance can be considered today as the main enabling system to sustain a target physical item - a workplace, a work equipment or means of transport - in a state in which it can perform the required function. In that way, whatever the sector is, workers carrying out maintenance activities are exposed to various hazards (e.g. chemical, physical, biological or psychosocial) that may be at risk of developing musculoskeletal disorders, diseases, etc. and occupational accidents (e.g. falls through or off something). Indeed maintenance can affect the health and safety not only of the workers directly involved in it, but of other people present in the workplace. To face this maintenance risk issue, risk assessment/management approaches are conventionally conducted by considering human, organisational or technical directions. Nevertheless such approaches are often not enough efficient because too focused on one direction without taking into account all its interactions with the others. Thus this paper presents a generic integrated risk management approach to maintenance which is based on a generic formalisation of maintenance (intervention) business processes/activities but also of their requirements more dedicated to health and safety. Then the approach and its resulting models have been automated on a tool called SPRIMI (software engineering) to be usable for information, support, training and design of safe maintenance system.

Risk of electrocution during fire suppression activities involving photovoltaic systems

Firefighting activities regarding buildings normally require electric power to be disconnected before a water jet is used, in order to minimize the risk of electrocution. As for as concerns Photovoltaic Systems, during a fire event it is not possible to turn off the whole power system in order to guarantee that all the components are de-energized. The object of this paper is to estimate the safe distances to respect during firefighting involving PV Systems. To this end a series of experimental tests have been performed, in order to measure the current flowing through the water stream, under different conditions of nozzle design, jet shape, water pressure and stream length. Experimental results have been compared with data in literature. Moreover, the electrical conductivity of the water streams, which actually consists of water mixed with air, has been evaluated.

Presse à servomoteur

L'arrivée sur le marché d'un nouveau type de presses, dites à servomoteur, pose des questions en matière de risques professionnels. Parce que leur fonctionnement diffère de celui des technologies conventionnelles, des investigations sont à mener pour analyser les fonctions de sécurité disponibles et leur efficacité en cas de défaillances des systèmes de régulation électronique.

A Wrench in the Gear

Lockout/tagout in the food industry
The food manufacturing industry includes animal slaughtering as well as the processing and packaging of meat, dairy, fruit, vegetable, grain, seafood, beverages, and bakery products. The industry employs nearly 1.5 million workers.1 Work in food manufacturing is typically fast-paced and workers can face exposure to hazards such as slips trips and falls, musculoskeletal disorders, and machine-related injuries.
Although there has been improvement in recent years, workers in food manufacturing have a higher rate of injuries and illnesses than workers in private industry as a whole. Many of the machine-related injuries are related to failure to use lockout/tagout (LO/TO) procedures. An examination of OSHA's Accident Investigation database (using SIC codes 201-207) showed that from 2003-2013, 28 fatalities and 227 serious injuries (such as amputations) were related to lockout procedures in food manufacturing.5 The largest number of incidents occurred in meatpacking and poultry slaughtering and processing.5  In fact, violation of the lockout/tagout standard (1910.147) was the most frequently cited infraction of an OSHA standard during 2012?2013 in food manufacturing with penalties totaling over $894,000.
