Flashcards in explosive tools fire extinguishers and haz materials Deck (45):

How does a low velocity tool drive a fastener?

1) The power load imparts sufficient energy directly to a fastener to cause it to penetrate base

2) The energy from the exploding power load acts directly on a piston, which drives the
fastener? ooooo


How does a high velocity tool drive a fastener?

1) The power load imparts sufficient energy directly to a fastener to cause it to penetrate base
materials. ooooo

2) The energy from the exploding power load acts directly on a piston, which drives the fastener?


For which types of structural loads are explosive actuated tool fasteners suited?

1) Tension load

2) Shear load

3) Static load ooooo

4) Approved for all loads


Which type of power load must be used in the low velocity tool?

1) Paper wad

2) Crimped end oooo


The color on the paper wad or end of the cartridge indicates?

1) High velocity or low velocity

2) Power level oooo

3) Material its rated for

4) Type of gun it’s to be used with


Power loads show the load strength by the casing material, Color code or power load level number?

1) True oooo
2) False


Power loads should not be carried loosely in pockets or aprons with drive pins or other metal objects.

1) Power loads may be set off, causing serious injury or death ooooo

2) The Color code or Power load number could be removed

3) They may become dented and fail to fire


Does a power load have to be approved by the manufacturer of the tool before it can be used in that tool?

1) yes ooooo

2) no


How are fasteners aligned and retained in the tool?

1) By the plastic guide strip

2) By the locking and guide mechanism

3) By guide member or head of the fastener oooo


Fasteners used in explosive actuated tools are manufactured out of what materials?

1) Tempered steel. ooooo

2) Recycled steel

3) Virgin steel

4) Platinum


Drive pins are approved for use of anchoring electrical conduit.

1) True oooo

2) False


A threaded knurled pin is best used with a hard steel base material?

1) True

2) False ooo


All fasteners are usually finished in?

1) Stainless steel

2) Zinc

3) Black Lacquer

4) All of the above oooo


What is meant by base material?

1) The material into which the fastener shank is driven

2) The material that the tip of the fasteners is made out of

3) The material from which the holding power is obtained

4) A and C are both correct oooo


The two materials that are not safe to fasten to when using an explosive actuated tool are?

1) Mild steel, OSB

2) Tempered steel, Spring steel oooooo

3) Extra hard steel, Press board

4) Tempered steel, Mild steel


Which one of these base materials that are too brittle to safely fasten to using an explosive
actuated tool.

1) Glass Block

2) Glazed tiles

3) Brick

4) All of the above oooo


Which of these base materials are too soft to safely fasten to using an explosive actuated tool.

4) All of the above ooooo


New concrete should be cured for how many days before fastening is attempted?

1) 1 day

2) 7 days oooo

3) 10 days

4) 12 days


Does spalling reduce the holding power of a fastener?

1) no

2) Yes

3) Only if the spalled area extends into the compressive bond zone oooooo

4) No the spalled area allows the fastener to penetrate deeper into the material


What is the recommended shank penetration for good holding power when fastening into concrete?

1) Two to four times the diameter

2) Six to eight times the shank diameter ooo

3) Eight to ten times the diameter

4) Ten to twelve times the diameter


What is the minimum recommended thickness of concrete that you can safely fasten to?

2) 75mm or 3 inches ooooo

3) 100mm or 4 inches

4) 150mm or 6 inches


When fastening into thin steel the fastener point should protrude 6 mm (¼ inch) to prevent
elastic action of the steel from forcing the fastener out.

1) True oooo

2) False


Fasteners should not be driven into steel thinner than what thickness?

1) Thinner than the pin’s shank diameter. ooooo

2) Thinner than the diameter of the fastener head

3) Thinner than the overall length of the fastener


Why is fastening through an existing hole in steel not recommended?

1) The fastener could shoot right through the hole and cause an injury

2) There would be a substantial reduction in the bonding strength of the fastener

3) The fastener could deflect ooooo
