Arc Flash Pre-Assessment By MR Powertech

Reduce the risk to personnel and equipment with arc-flash prevention and detection solutions. An arc-flash event can release heat up to 19,427°C, but detecting these dangers and tripping circuits quickly reduces the incident energy, protecting personnel from severe burns and equipment from explosive hazards. With trip times measured in milliseconds, a pre-assesment arc-flash helps you to explore if you need special work done to prevent severe injury and death, equipment damage, system downtime, and regulatory penalties.

General information
Comments


Participants

info: Electrical safety plan is an official document, in some countries mandatory. It provides information about electrical networks, rules for the safe operation of electrical installation, and identifies risks related to it including arc flash, shock hazard and ATEX etc also provides information about required Personal Protective Equipment, a list of authorised personnel, training and more.


info: Electrical one-line diagram is an overview of an electrical system and is used for example for LOTO identification 


info: Arc Flash Risk Assessment identify incident energy hazard from an electrical arc in cal/cm2 in electrical panels across the facility.


It needs to be up to date and no older than 5 years


The requirements according to IEEE 1584.1 and NFPA70E (or local standards and requirements)


Arc Flash training is typically dedicated to the electrical maintenance team, safety personnel, facility team, etc.


Info:

All electrical panels identified by arc flash risk assessment require labels (to be confirmed by the responsible engineer)


info: Arc Flash report should provide information how to improve safety if arc flash incident energy is bigger than 1.2 cal/cm2 and investigate possible improvements and mitigation techniques 


info: Arc rated PPE is rated with ATPV, EBT50 or ELIM  test values usually given in cal/cm2 and shock hazard PPE
