CSA Z462-2021 Standard

CSA Z462-2021 Standard

This blog is a continuation of the one published in 2020 on the probable changes of the CSA Z462 standard in 2021, related to the changes of the American standard NFPA 70E 2021. Following the release of the new version of the CSA Z462-21 standard, the first important point is that the revision of the CSA Z462 standard does not consider the changes of the NFPA 70E 2021 standard.

Likely Changes Coming to CSA Z462:21 Based on NFPA 70E

The 2021 version of standard CSA Z462 will be released in the coming months. Since it makes changes based on the American standard NFPA 70E, we analyzed the latter, which just released its new revision, to predict probable changes to appear in the CSA Z462 standard in 2021. Standard NFPA 70E contains minor changes from its previous version. In 2021, the committee’s goal is to refine the articles and link them with current safety rules, i.e. risk reduction at the source.

Analysis of electric shock which could have been avoided

Analysis of electric shock which could have been avoided

According to Tucker and Keefe (2019) of the University of Regina, the annual percentage of non-fatal accidents in Quebec between 2010 and 2017 remained relatively constant (slightly less than 2%). The rate of fatal accidents fell slightly during the same period, from 2.6 to 1.6 (per 100 000). For example, with regard to accidents related to electricity, in 2018 this represented 164 cases and 161 in 2017, a little more than 2 per day on average (CNESST, 2019).

Z463-18: Maintenance of electrical systems

Z463-18: Maintenance of electrical systems

The CSA Z463 went from a guideline on maintenance of electrical systems to a standard on maintenance of electrical systems in 2018.
The purpose of this standard is to facilitate the reliable and cost-effective performance of electrical systems by developing risk assessment techniques and maintenance programs.

Means of maintenance for electrical installations

Means of maintenance for electrical installations

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.

The integration of OHS management into the general management systems of businesses

The integration of OHS management into the general management systems of businesses

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 key changes to IEEE-1584-2018.

The key changes to IEEE-1584-2018.

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.

The importance of arc flash study and keeping it up to date

The importance of arc flash study and keeping it up to date

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).

The economic benefits of the arc flash study

The economic benefits of the arc flash study

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.
