"Electric arc is a complex phenomenon"

Arc flash incidents are one of the most deadly risks on the

worksite, with arc flashes able to kill at distances of as little as

10 feet. More than three quarters of those questioned in an arc

flash mitigation survey said reducing the risk of arc flash was an

essential consideration, yet only 67% of respondents stated

they had completed an analysis.

Why?

Perhaps a part of the problem is that there’s really no such thing

as an ‘arc flash analysis’. Instead, this term has been created by

combining ‘incident energy analysis’ and ‘arc flash risk

assessment’… so which one should you be focusing on? Both.

Incident energy analysis should be an integral part of an arc

flash risk assessment, and conducting this assessment is

something that all businesses working onsite with electrical

equipment should be prioritising. Under the European Council

Directive 89/391/EEC, all employers have a legal responsibility

to assess and identify the level of risk at work.

So how do you conduct an arc flash risk assessment?

There are two stages. The first stage covers the first 3 aspects

of the Health & Safety Executive’s 5-step plan for undertaking a

workplace risk assessment: identifying hazards, determining

who is at risk and how, and considering the most effective

precautions. This stage involves examining your electrical

equipment type and voltage to generate a minimum arc rating in

calories/cm2 and the overall arc flash boundary.

Conducting an arc flash risk assessment and calculating incident

energy can take time, yet it’s one of the most effective ways to

minimise risk and ensure that all workers fully understand the type

of personal protective equipment they should be wearing onsite.
