Tip of the Month- To Guide Your Company’s Future, Look to Its Past

Each company has its own DNA: a unique strategy and culture that sets it apart from competitors.

To guide an organization’s growth, you need to understand its nature. Start by looking at its past. Dig around in the company archives. Talk to early employees to find out what the organization used to be like and what shaped its beginning. Read the corporate history, if you’ve got one. Look at the original vision and values of the founders. How did they see the world? What problem were they out to solve? How did they believe the business was creating value?

Map what you learn to the company’s current business. Where is there alignment? Where isn’t there? The goal of this exercise isn’t just to increase your understanding of the company; it’s to think about how the company can create value in new ways while staying true to its origins.

Electric Arc Flash PPE

According to the NFPA 70E, Arc Flash is a “dangerous condition associated with the release of energy caused by an electric arc.” It is measured in terms of arc flash incident energy E (AFIE), which is used to determine the level of Personal Protective Equipment (PPE).

An arc flash is the light and heat produced from an electric arc supplied with sufficient electrical energy to cause substantial damage, harm, fire, or injury. This can occur near high power electrical equipment such as transformers, service entrance switch gear or generators.

The first step to protection conduct an Arc Flash Hazard Analysis which defines the procedures and limits the damage of electrical arcs on personnel and, by measuring the released energy, defines the risk and determines the relevant level of the PPE required.

 HRC* 0 –  0 cal/cm2 ; 0 J/cm2: Non-melting, flammable materials (i.e untreated cotton, rayon, wool, silk or blends of these materials) with a minimum fabric weight of 150g/m2
 HRC* 1 – 4 cal/cm2 ; 16,74 J/cm2: Arc Rated Flame Retardant shirt, Flame Retardant trousers or Flame Retardant coverall
 HRC* 2 – 8 cal/cm2 ; 33,47 J/cm2: Arc Rated Flame Retardant shirt, Flame Retardant trousers or Flame Retardant coverall
HRC* 3 – 25 cal/cm2 ; 104,6 J/cm2: Arc Rated Flame Retardant shirt and FR trousers or FR coverall, and arc flash suit selected so that the system arc rating complies with the required minimum
HRC* 4 – 40 cal/cm2 ; 167,36 J/cm2: Arc Rated Flame Retardant shirt and FR trousers or FR coverall, and arc flash suit selected so that the system arc rating complies with the required mini

*HRC:  Harzard/Risk Category

Selecting the correct level of Arc Protection Equipment (APE) is made easy from this table however there are a few questions to ask your APE supplier:

  • Is the garment compliant with SANS 724:2010, NFPA 70E:2009 and SANS 984/IEEE Std 1584?
  • Can they send you the relevant certifications?
  • Does the garment meet your required HRC level?
  • Has the garment been tested? (not the fabric – very important)
  • If so, can they send you the test reports that include photos?

It’s important to note that where more than 40cal/cm2 APE is required it is not recommended unless all other means of reducing the risk of exposure has been investigated.

The Arc PPE you use really is your last line of defence, and following the above steps ensures that you are doing the best you possibly can to minimise injuries as a result of an arc flash incident.
