In Quebec, the health and safety of workers is a priority framed in section 2 of the Occupational Health and Safety Act (LSST), which defines its purpose by eliminating at the source of the hazards to health, safety and health and physical integrity of workers. In this definition, the dangers to the health, safety and physical integrity of workers are absolutely referred without mentioning any particular criterion to avoid any possibility of misinterpretation that may lead to depreciation or to neglect one or more corrective measures. However, because of the severity and the high frequency of certain situations, the CNESST has identified nine (9) points with zero tolerance that concerns all work environments.read more
In a workplace, ergonomics scientifically establishes, through the design of systems, the relationships between man, his tools, his methods and his workstation to ensure his comfort, safety and performance when carrying out his work. According to the “Society of Ergonomics of French Language”, this discipline is the science that includes both physiological knowledge or related sciences applied to human work in the perspective of a better adaptation to humans. It aims to understand the constraints factors specific to each workstation to make improvements by considering all the elements to determine how the work is done. It’s about the physical area, the physical development, the safety conditions, the amount of operations or informations to be used, the rate, the schedules and the physical characteristics of the operators (size, weight and gender).read more
One of the most frequently asked questions concerning the fastening of permanent protectors is the possibility of using a padlock as a means of fastening (conformity of fastening with a padlock).
It is a question that appears simple, but quickly becomes ambiguous when we try to rely solely on regulatory articles and applicable standards. This is a gray area where no clear answer can decide as to the conformity of this action. For this reason, deeper understanding and interpretations are needed to line up our actions with the true goals of these texts.
Lorsqu’un équipement électrique est utilisé dans un endroit caractérisé par une présence de gaz ou liquide, fibre ou poussière inflammable, un risque d’incendie ou d’explosion devient plus considérable. Les endroits où ce risque est à prendre en compte sont appelés des emplacements dangereux ou classifiés. La classification peut se faire selon deux systèmes, soit le système des classes/divisions et le système des zones.read more
The stick is a tool that simulates the limb you wish to keep from the danger zone (e.g. finger, hand, arm). Performing the permanent protector’s conformity check is done simply by making sure that the stick cannot reach the danger zone when inserted through the openings of the protector, according to its smallest opening.read more
For access to a danger zone during maintenance activities or assembly and installation activities, lockout or, in absence of lockout, any other energy control method that ensures equivalent safety must be applied, according to RROHS article 188.2. These other energy control methods are sometimes called ‘’alternative methods to lockout.’’read more
Many alternatives are available to allow for efficient control of access to the danger zones of equipment. The choice of one or many of these alternatives is mainly based on the need to access the danger zone, the frequency and the nature of the tasks to be performed inside the danger zone.read more
Access to the danger zone of a machine during maintenance, or even setup and installation activities, should only be allowed once all energies have been controlled by use of lockout, according to article 188.2 of ROHS.read more
