Article 210

What is the NEC definition of a “Qualified Person”? Article 100 in the NEC defines a qualified person as: “one who has the skills and knowledge related to the construction and operation of the electrical equipment and installations and has received safety training to recognize and avoid the hazards involved.”

2017 NEC Building: A structure that stands alone or that is separated from adjoining structures by fire walls. The definition of the word building was revised and the term “fire doors” was deleted because openings in firewalls are not limited to just doors.

A nonprofit organization whose purpose is to reduce the worldwide burden of fire and other hazards on the quality of life by providing and advocating consensus codes, standards, research, training, and education. Standard for wildland fire fighter professional qualifications.

NFPA publishes more than 300 consensus codes and standards intended to minimize the possibility and effects of fire and other risks. NFPA codes and standards, administered by more than 250 Technical Committees comprising approximately 8,000 volunteers, are adopted and used throughout the world.

REILLY4; R-EBT stands for Reilly Emergency Breathing Technique It consists of: Breathing in normally through the nose; • Breathing out through the mouth, partially opening it, and extending the exhalation.

Wheel breathing is a very effective and proven technique that we as firefighters can use to extend our cylinders when in an emergency situation. Give it a shot after a solid workout and work hard to slow your breathing down as quickly as possible.

(1) Skip breathing – A normal inhalation held for several seconds, followed by an additional inhalation before exhalation. (2) Box breathing – A slow inhalation over 3-4 seconds, hold for 3-4 seconds, exhale over 3-4 seconds, and then hold for 3-4 seconds before the next inhalation.

The SCBA supplies the compressed oxygen from the oxygen cylinder to the wearer through cylinder valve, pressure reducer, demand valve, etc. Carbon dioxide in exhales air is absorbed by the absorbing canister, and oxygen is re-supplied through breathing bag. This mechanism enables for long time use.

Service life for SCBA cylinders is currently limited to 15 years by U.S. Department of Transportation (DOT) Code of Federal Regulations and Special Permits issued to SCBA cylinder manufacturers.

SCBAs are extremely expensive, with each SCBA unit & mask costing in the ballpark of $5,000 per set. Each firefighter normally will use at least two cylinders on the scene of fire, and each spare cylinder costs in the area of $1,500.

An SCBA typically has three main components: a high-pressure tank (e.g., 2,216 to 5,500 psi (15,280 to 37,920 kPa), about 150 to 374 atmospheres), a pressure regulator, and an inhalation connection (mouthpiece, mouth mask or face mask), connected together and mounted to a carrying frame.

Limitations: SCBA units are expensive to purchase and maintain; require the wearer to carry 20 to 30 pounds of equipment on their backs, and provide no more than 40 minutes of continuous use. Personnel with facial hair which comes between the respirator sealing surface and the wearer’s face cannot use SCBA equipment.

There are two major types of SCBA that are in use today – the Open Circuit SCBA and the Closed Circuit SCBA.

There are 3 main types of Breathing Apparatus – Escape, Self-Contained and Airline.

One of the most common uses for an SCBA is in confined space entry. Some others SCBA applications include working with liquid spills, gas exposure that produce (or could produce) IDLH conditions, and so many more: First response emergency rescue of people overcome by atmospheric hazards (e.g. firefighting)

The full-facepiece, closed-circuit (CC) self-contained breathing apparatus (SCBA) is designed to protect personnel in hazardous, toxic, or oxygen- deficient environments. The CC-SCBA recirculates breathing air and purifies it, removing carbon dioxide and adding fresh oxygen.

The closed-circuit type, also known as a rebreather, operates by filtering, supplementing, and recirculating exhaled gas. It is used when a longer-duration supply of breathing gas is needed, such as in mine rescue and in long tunnels, and going through passages too narrow for a big open-circuit air cylinder.

SCBA units were not designed for use in deep water; a pressure greater than approximately five feet or 2.5 psi may cause the unit to malfunction. Breathing underwater involves an increased pressure of approximately 0.5 psi per of water. At the surface, normal atmospheric pressure is 14.7 psi.

SCBA Information. A self-contained breathing apparatus (SCBA) is a type of respirator that contains breathable compressed air. This document will focus, primarily, on open circuit, positive pressure-demand SCBAs. This is the type worn by firefighters and the most commonly used SCBA.

Certainly pressure demand SCBA, pressure demand and continuous flow SAR, and PAPRs are positive pressure respirators according to these definitions.

To conduct a positive pressure check, follow this procedure:

1. Don the facepiece and adjust so it’s snug but not overly tight.
2. Using the palm of your hand, block the exhalation valve, usually found on the bottom of the respirator.
3. Gently try to breathe out, which should allow the facepiece to puff out slightly.
