highlights
Highlights
  • The purpose of the Life Safety Code is to establish minimum requirements that will provide a reasonable degree of safety from fire and similar emergencies in buildings and structures.
  • To apply the Code effectively, one must understand the legal authority of the Code in various jurisdictions; be familiar with the layout and content of the Code;
  • understand how to navigate through the Code; and have a thorough understanding of how proper application of the Code can minimize the effects of a devastating fire or other emergency.
what is the ibc
What is the IBC
  • First published in 2000 by international Code Council
  • Complies regulation from BOCA (Building Officials and Code Administrators International), Uniform Building Code-ICBO (International Conference of Building Officials), and SBCCI (Southern Building Code Congress International)
  • Updated every 3 years
  • 35 chapters, 10 appendixes, and an Index
occupancy types
Occupancy Types
  • Chapter 3
  • A,B,E,F,H,I, M,R,S, U
  • Some occupancies have numbers attached
    • A-3: assemblies for worship, recreation

The number reflects the degree for which the area is being used.

chapters 1 10
Chapters 1- 10
  • Set up like NFPA 101
    • Means of egress, fire protection, interior finish, rated construction
    • Chapters are more in depth
summary
SUMMARY
  • NFPA 101 and IBC
      • There is no national or worldwide building code.
      • Both codes reference one another
      • Federal Government requires NFPA for hospitals participation in Medicare and Medicaid programs
      • State agency along with municipalities may use IBC but want to use NFPA for egress.
      • IBC geared toward construction and life safety
      • NFPA 101 is more for life safety in different occupancies

Fire Extinguisher Training Requirements.

29 CFR 1910.157(g)

Where the employer has provided portable fire extinguishers for employee use in the workplace, the employer shall also provide an educational program to familiarize employees with:

  • the general principles of fire extinguisher use and
  • the hazards involved with incipient stage fire fighting
  • upon initial employment and
  • at least annually thereafter.

fire extinguishers1
Fire Extinguishers
  • TYPES OF FIRE
  • Class A - Combustible material
  • Class B - Flammable liquid
  • Class C - Electrical
  • Class D - Combustible metals (not as well known)
  • Class K- Kitchen
fire extinguishers2
Fire Extinguishers
  • Extinguisher types
  • The fire equipment manufacturers refer to three basic types of hand portable fire extinguishers:
  • 1. Stored pressure
  • 2. Cartridge operated
  • 3. Sealed pressure
fire extinguishers3
Fire Extinguishers
  • The difference lies mainly in the sealing method and the means by which the container is pressurized
fire extinguishers4
Fire Extinguishers
  • Classified as either stored pressure or cartridge operated, they are additionally classified by Underwriters Laboratory (UL) as:
  • ABC - (Ammonium Phosphate).
  • BC - (Sodium Bicarbonate; Purple K). or
  • D - (Super D or Sodium Chloride), Copper, or G-Plus (Graphite).
fire extinguishers5
Fire Extinguishers
  • Stored pressure

In stored pressure models the expellant gas and extinguishing agent are stored in a single chamber and discharge is directly controlled by the valve

fire extinguishers6
Fire Extinguishers
  • Stored pressure

These units have the advantage of being easily inspected since most are equipped with a pressure gauge indicating that the unit is ready for use.

fire extinguishers7
Fire Extinguishers
  • Stored pressure

Once used this unit requires special recharging equipment and is normally returned to the fire department for recharge

fire extinguishers8
Fire Extinguishers
  • Cartridge operated

With cartridge operated fire extinguishers, the expellant gas is stored in a separate cartridge located within or adjacent to the shell containing the extinguishing agent

Fire Extinguishers

Sealed pressure

Sealed pressure fire

extinguishers are much the

same as stored pressure units

and are often referred to as

disposable-non refillable

types

fire extinguishers10
Fire Extinguishers

Sealed pressure - cont.

The expellant gas and

extinguishing agent are both

stored in a single chamber,

but differ from stored

pressure units in that sealing

is accomplished by means of

a frangible metal disc as

opposed to a valve

fire extinguishers11
Fire Extinguishers

Wheeled Units

Wheeled units are also

considered portable

extinguishers and are

nitrogen cylinder operated

dry chemical units. They are

available in sizes ranging

from 75 pounds to 350

pounds. They can be used on

Class A, B and C fires

depending on the agent used.

fire extinguishers12
Fire Extinguishers

Portable fire extinguishers must be visually inspected monthly. The inspection should assure that:

1. Fire extinguishers are in their assigned place;

2. Fire extinguishers are not blocked or hidden;

3. Fire extinguishers are mounted in accordance with NFPA Standard No. 10 (Portable Fire Extinguisher);

4. Pressure gauges show adequate pressure (CO2 extinguisher must be weighted to determine if leakage has occurred);

5. Pin and seals are in place;

6. Fire extinguishers show no visual sign of damage or abuse;

7. Nozzles are free of blockage.

Extinguisher Placement (Travel Distance)

The following chart contains OSHA requirements for classes of fires and

travel distance to an extinguisher.

Some local requirements may be stricter, so you should always check with your local fire marshal / fire prevention office.

  • Fire Class Travel Distance
  • Class A *75 ft. (22.9m) or less
  • Class B 50 ft. (15.2m)
  • Class C Based on appropriate A or B Hazard Class.
  • Class D 75 ft

“P” for PULL

“A” for AIM

"S“ for SQUEEZE

“S” for SWEEP

Remember……….

The average hand portable extinguisher will only operate for 30 seconds ----- There is NO TIME to learn during an actual emergency.

IN CASE OF FIRE

Evacuate the building

Call the fire department

Make sure the fire is small

Make sure you have a clear way out
