Curtain wall

Non load-bearing exterior wall attached to the outside of a building.

Fire partitions & fire barriers

___ _______ _ ____ _____ are vertical building elements. They are walls & shafts enclosures that have fire resistant ratings. Number of openings is limited. Openings & penetrations must be rated too.

Horizontal Assemblies

________ __________ are floor or ceiling, ceiling or roof assembly that has fire resistant rating.

Walls, Floor & Ceiling

_____, ____ & _____ assemblies surrounding an area having the same fire-resistance rating create complete compartmentation or enclosure.

ASTM E119

Standard Test methods for Fire Tests of Building Construction and Materials

UL 263

Standard for Fire Tests of Building Construction and Materials

NFPA 221

Standard for High Challenge Fire Walls, Fire Walls, and Fire Barrier Walls

ASTM E-119 & UL 263

These two are testing standards for walls that ensure an assembly can resist fuel loading through heat transfer.

Fuel loading

___ ______ is when materials (ie. Boxes, wall paper, books) on one side of a wall are subjected to enough heat transfer from the opposite side of the wall that they ignite.

one-hour

When it comes to a fire barrier, the IBC requires that it must have no less than a __-_____ fire-resistance rating.

However, rating requirements for this can extend to a four-hour rating depending on the type of occupancy of a particular building.

30

On the other hand, a fire partition must have a fire-resistance rating of no less than _____ minutes.

do not, same level

According to IBC, fire partitions ___ ____ provide the ____ ____ of protection as fire barriers.

1 hour

Fire partitions must have a rating of at least ___ _____.

Automatic Sprinkler system

If fire partitions are less than one-hour rated, an ____ _____ ______ must be installed.

prevent the passage

Fire rated doors are used in buildings to _____ ___ ______ of fire and smoke between two compartments or areas.

NFPA 80

Standard for Fire Doors and Other Opening Protectives -- installation and maintenance of fire doors.

doors and frames

The International Building Code and International Residential Code require that _____ ____ _______ be given a fire-resistance rating after extensive testing by an approved agency.

20, 3

Fired rating doors & frames vary from __ min to _ hours, which represent the duration of the fire protection.

steel

Only ____ doors and frames have earned a three-hour rating.

110 V and 220 V

These are the 2 distinct types of power sources you will find in your home.

110

The most common electrical outlet in any home is a ___ volt.

15 amp & 20 amp

What are the two variations of the 110 volt outlet?

110 Volts & 15 Amp

This is suitable for the majority of your electronic needs, such as TVs, microwaves, small air conditioners, etc.

110 Volts & 20 Amp

Small dryers and washing machines often use this socket.

220 volt

With the increased electrical demands of larger appliances, such as ranges, the power supply is doubled by combining 2 circuits and creating a _______ outlet.

15, 20, and 30 Amp

What are the three types of variations for a 220 volt outlet?

220 Volt & 15 Amp

More powerful appliances increase the demand on your electrical system. These are larger plugs than normal 110 Volt, and it would be impossible to confuse the two. Washers, dryers, and commercial-sized air conditioners commonly use this plug.

Safety, expenses

Why not make all outlets 220 volts?

Two areas of concern:
1. _____
2. _______

220 volt outlet uses

This volt outlet is for rooms with appliances such as a washer, dryer, oven, furnace, etc that require the extra voltage.

Ground-Fault Circuit Interrupter

This is an inexpensive electrical device that can either be installed in your electrical system or built into a power cord to protect you from severe electrical shocks. GFCIs have played a key role in reducing electrocutions.
