Arc Flash Expertise
Arc flash (also known as arc blast) is a phenomenon where a flashover of electric current leaves its intended path and travels through the air (electric short circuit in air) between phase, or phase and neutral, or phase and ground conductors. It is a type of electrical explosion that results from a low impedance connection to ground or another voltage phase in an electrical system.
An arc is produced by flow of electrical current through ionized air after an initial flashover or short circuit. Causes of arc flash include:
- Electrical equipment and insulation failure
- Accidents, such as:
- Dropped tools
- Accidental contact with electrical systems
- Buildup of conductive dust, dirt, corrosion and particles
- Improperly designed or utilized equipment
- Improper work procedures
How can we help?
Through an arc flash safety analysis, Optimation's skilled engineers can offer alternatives to help your organization become more aware of possibilities to reduce your employee's exposure to arc flash energy. We can help you by:
- Designing power systems that are safer and assist with regulatory standard compliance
- Providing integrated short circuit, time current coordination, equipment, arc flash evaluation and arc flash labels
- Providing arc flash hazard analysis for flash protection and approach boundaries
- Selecting Personal Protective Equipment (PPE) for electrical safety
- Assisting in the implementation of a solution(s) to reduce arc flash exposure
- Providing critical arc flash hazard training for your internal team
Why is an Arc Flash Safety Analysis important to your organization?
It's a regulatory requirement.
80% of electrical workplace accidents are burns or injuries caused by intense heat, tremendous pressure and sound blast due to molten metal or debris shower associated with arc flash. These accidents are the fourth leading cause of traumatic occupational fatalities in the U.S. Electrical workplace accidents lead to injury and sometimes death, however these accidents can be prevented.
In an effort to prevent electrical workplace accidents, the Occupational Safety and Health Administration (OSHA) published the Occupational Safety and Health Standards (OSHA 1910) which covers electrical safety in the workplace in addition to workplace safety topics.
In addition, the National Fire and Protection Agency (NFPA) has published the "Standard for Electrical Safety in Workplace" (NFPA 70E). The NFPA 70E standard responds to electrical safety challenges, making it easier to ensure an electrically safe working area. OSHA 1910 references NFPA 70E for specifics on electrical safety.
Implementing NFPA 70E by becoming OSHA 1910 compliant, is highly recommended for a safe workplace.
