So what is the NFPA 70 E?
• The Purpose of the 70E Standard is to provide safe working guidelines and practices to ensure employee safety when working on electrical systems
• First published in 1979- It is a appendix to NFPA 70 or known more commonly as
the NEC.
• Consists of several updated versions- 2000, 2004, 2007, 2009, 2012, 2015
- Working on 2018 updates.

NFPA-70E 90.2
This standard addresses electrical practices for
employee workplaces that are necessary for the
practical safeguarding of employees relative to
the hazards associated with electrical energy.
This standard also includes safe work practices
for employees performing other activities that
expose them to electrical hazards

130.7(J) Anticipating Failure
When there is evidence that electrical
equipment could fail and injure employees, the
equipment shall be deenergized. Until the
equipment is deenergized or repaired,
employees shall be protected from hazards
associated with impending failure by suitable
barricades or other alerting techniques
necessary for the safety of employees.

WHY SHOULD I HAVE AN ARC FLASH RISK ASSESSMENT?
1.OSHA General Duty Clause which states: Each employer shall furnish to
each of his employees employment and a place of employment which are
free from recognized hazards that are causing or are likely to cause death
or serious physical harm.
2.OSHA 29 CFR 1926.960(g)
1.Hazard assessment. The employer shall assess the workplace to
identify employees exposed to hazards from flames or from electric
arcs.
2.Estimate of available heat energy. For each employee exposed to
hazards from electric arcs, the employer shall make a reasonable
estimate of the incident heat energy to which the employee would be
exposed.
3.OSHA 29 CFR 1910.335 Employees working in areas where potential
electrical hazards exist shall be provided with and shall use personal
protective equipment.

Risk assessment cont.
• NFPA 70e 110. A The employer shall implement and
document an overall electrical safety program that directs
activity appropriate to the risk associated with electric
hazards. The electrical safety program shall be implemented
as apart of the employer’s overall occupational health and
safety management system, when one exists.
