Rather than safety or maintenance practices, NFPA 70 revolves around installing and maintaining electrical equipment. Its intent is to provide practical safeguarding practices that can protect both people and property from electrical hazards that can arise when users install electrical components.
NFPA 70E is a standard of the National Fire Protection Association (NFPA) that addresses electrical safety requirements for employees in the workplace and details how to protect workers from the heat of electric arc exposures.
A common rule that is followed for obstructions within 18 inches of the sprinkler deflector is the “three times rule”. This requires sprinklers to be positioned away from obstructions a minimum or three times the maximum dimension of the obstruction.
A: Some of the key requirements of NFPA 72, National Fire Alarm and Signaling Code include: providing fire alarm systems that are designed, installed, inspected, tested, and maintained to meet the code's standards, providing fire alarm control units that are designed and installed to detect fires and initiate an alarm ...
While NFPA 70E training is NOT required by law except for contractors to the Department of Energy [10CFR 851.23(a)(14)], meeting OSHA requirements for electrical safety training IS required by law.
Summary. Although OSHA may not specifically enforce NFPA 70E, they can and have cited electrical safe work practice hazards with existing OSHA standards.
Difference Between NFPA 70 (NEC) and NFPA 70E
While NFPA 70E tells employers how to keep their workplace safe and the specific procedures they can put in place, NFPA 70 (NEC) goes into detail about how to design and install safe and effective electrical systems.
NFPA 70, or the National Electrical Code (NEC), is a code for installing and maintaining electrical systems in buildings. It covers topics such as proper wiring techniques and safety measures to be taken when working with electricity. On the other hand, NFPA 72 is a code specifically for fire alarm systems.
Calculating the Number of Detectors per Area
Per Square Footage: Generally, one smoke detector is recommended for every 500-1,000 square feet of floor space.
Ultimately, the NFPA, your local AHJ, as well as your insurance company will determine whether or not you are required to have both. There are some instances where having an adequate fire sprinkler system may free you from an obligation to install and maintain a fire alarm.
The Rule of Three for learning establishes the requirement that students be given the opportunity to learn something at least three times before they are expected to know it and apply it.
NFPA 20 protects life and property by providing requirements for the selection and installation of pumps to ensure that systems will work as intended to deliver adequate and reliable water supplies in a fire emergency.
The overall enforcement (AHJ) for NFPA 70E is therefore the employer. It is their responsibility to establish, document, and implement the safety-related work practices and procedures required by NFPA 70E and to provide employees with training in safety related work practices and procedures.
NFPA 13 covers the installation of fire sprinkler systems; NFPA 72 covers equipment related to fire alarm systems.
NFPA 70E certification is valid for three years, at which time you will be required to recertify to maintain your education at a top-level. It should be noted the NFPA 70E, Standard for Electrical Safety in the Workplace is revised on a three-year cycle.
Because smoke rises, you should place alarms on the ceiling. If you cannot do this, place them high up on a wall according to manufacturer's instructions. Most importantly, read the installation instructions that come with the alarm.
One alarm can cover multiple rooms if you place them outside sleeping areas within 21 feet from its door. If there is a door to an upper floor or the basement stairs, install one detector on each side of the door. Install a sensor every 500 square feet if you have a house that is bigger than 1,000 square feet.
The NFPA recommends that you install a carbon monoxide alarm, like smoke alarms, on every level of your home, inside every bedroom, and outside each sleeping area. Make sure carbon monoxide detectors are also installed near attached garages in case a car is left running, and anywhere else the manufacturer recommends.
NFPA 70E is a voluntary safeguard that can help protect your workers from electrical hazards and ensure a safe working environment. While the standard is voluntary, complying can protect your employees from injury and your business from potential OSHA violations.
Install smoke alarms inside and outside every bedroom and sleeping area (like a hallway). Install on every level of the home, including the basement. A smoke alarm should be on the ceiling or high on a wall. Keep smoke alarms away from the kitchen to reduce nuisance, or false, alarms.

The guidance document provides guidance on how to interpret selected articles of NFPA 70, “National Electrical Code” (NEC), in particular certain articles within Article 590, “Temporary Power,” for D&D electrical activities at DOE sites.
Authorities having jurisdiction (AHJ) are a big deal in fire protection. They feature heavily in the standards and codes of the National Fire Protection Association (NFPA) as the ultimate arbiter of what will or won't work in terms of a structure's fire protection measures.
Circuit breakers trip and fuses blow, which show that too much current is flowing. This could be due to a number of factors, such as malfunctioning equipment or a short between conductors. An electrical tool, wire, or connection that feels warm may indicate too much current in the circuit or equipment.
