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
NFPA 51B is full of useful information on the best practices for hot work. Along with the National Fire Code of Canada and CAN/CSA W117.2-M87 Safety in Welding, Cutting, and Allied Processes, it is essential reading to provide framework and safely perform hot works in conformity with the Safety Code for the construction industry (SCCI) and the Regulation respecting occupational health and safety (RROHS).read more
Do you know the risks of working with ladders?
Your mind might go straight to falls and resulting injuries, but did you know that electrification and electrocution are frequently associated with the use of these tools?
Here’s how you can reduce your risks for many types of accidents in five simple steps:
In Quebec, cool weather quickly gives way to summer heat. It is not uncommon to have a first heat wave at the beginning of June. This meteorological phenomenon leads to hot thermal stress “heat stroke” in many workers, because their bodies are not yet used to a warm environment.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.
Did you know that mobile equipment is subject to the same regulatory requirements as any other type of equipment or industrial machine where lockout is concerned? Articles 188.1 to 188.13 of RROHS apply to all “machines”. This means, among other things, that mobile equipment should be included in your lockout program and that a lockout procedure (lockout card) should be available for each device. The inclusion of mobile equipment is also provided for in standards such as CSA Z460-13.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
In this blog, it will be presented the different electrical risk assessment methods as well as the proper PPE to use for live work.read more
Have you ever been confronted with any of the following questions? Can an operator activate disconnect devices by him or herself? Can an electrician work under voltage or near a voltage source? …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
Maintenance of electrical apparatus allows for improvement of reliability, increased lifespan and reduced allotted maintenance time. There are three modes of maintenance: reactive maintenance, preventive maintenance or predictive maintenance.
The difference between the three modes is mainly related to the time allotted to maintenance personnel and the diagnostic equipment available to detect anomalies.
In theory, any organization can be classified into one of the two following categories:
1- Businesses that choose to handle OHS questions on a case-by-case or day-to-day basis.
2- Businesses that prefer to handle the health and safety of their human capital in a more proactive manner.
The IEEE-1584 standard is used to calculate the incident energy level, or the heat released during an arc flash explosion. This standard appeared in 2002 and is based on statistics, physics and empirical formulae to accurately estimate the heat to which a person could be exposed if situated 18 inches from the electric arc.read more
The Electrical Safety Program (ESP) is created and offered by a company to require workers to use safe work methods for live electrical work and prioritize de-energized work.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
With the CSA Z460 standard and the regulatory changes in Quebec, the aim is to find the most reliable method for validating the absence of electrical energy.read more
An incident energy (arc flash) study allows updating of the plant’s electrical plan(s), clear identification of each electrical equipment, targeting of protective equipment that are likely to falter during a short circuit and allows electricians, mechanics, refrigeration technicians and other qualified persons to use the right category or arc rating for personal protective equipment (PPE).read more
In Quebec in 2013, three workers died and 601 were injured in accidents caused by forklifts. Also, between 2017 and 2018, 8 fatal accidents were directly or indirectly related to the use of forklifts.read more
Workplace accidents in general, and more specifically those attributed to machines, represent a major issue at the human and financial levels for both the employee, the employer and society.read more
An incident energy (arc flash) study allows knowledge of the real incident energy level and the robustness of protective equipment: breakers and fuses. If an enterprise has never done an arc flash study, a first incident energy study could reveal several defects and prove to be very costly for the replacement of safety equipment.read more
