yourself
2

16
Q
Competent person vs Qualified person
A
- has experience to carry out a certain task
- has been trained via education, school
- more clought will come from a competent person (they have to know risks, soil (cave-ins), etc.)
- trust a competent person more than a qualified person
17
Q
Record Keeping
A
- All accidents must be reported
- worker comp
- sounds silly, but still report in case of infection and festering
18

A
Falls - #1 cause of accidents
Struck-by - hit by something
Caught in between - confined spaces and can’t move
Electrical - Shock
19
Q
JSA - Job Safety Analysis and TSA - Task Safety Analysis
A
- Review tasks at hand and hazards
20
Q
How do you protect yourself from falls?
A
- Fall protection: body harness and laniard attached
- chains guard rails
- 6ft or more above the ground fall protection is required
- put a barricade on trenches
- guard rails on places without windows and just a hole in the wall
21
Q
How do you guard a hole in the ground?
A
- a cover plate must be able to hold 2 times the intended weight
- Guard rails
- Caution tape
- fence
- construction fences
- caution that there’s a temporary cover
22
Q
What is the toeboard on a scaffold?
A
prevents equipment/material from falling off the scaffold.
23
Q
Laniard info
A
- must have shock absorb
- needs to be short enough to protect you from a fall
24
Q
Ladders
A
- have a weight length
- Aluminum step ladder 300lbs
- Fiberglass step ladder 375lbs
- ladders are not all made the same
25
What kind of ladder must be used when working with electricity?
Fiberglass step ladder
26
volts to stop heart
0.1 amps or 1 milliamps
27
Where does electricity naturally want to go?
return back to the ground
28
Step ladder and extension ladder
the safest standing height on the extension ladder is 4 rungs from the top
2 rungs from the top on step ladder is the safest
Get a bigger ladder is standign on the top of a step ladder.
29
Ladder ratio
4 to 1
every 4 ft on a wall the ladder must go out 1 foot
30
What is a key safety guideline for using a ladder to access a roof?
ladder must extend 3 ft past the roof
31
What are two essential safety tips for maintaining stability while using a ladder?
one limb at a time on a ladder/3 points of contact on a ladder at all times
32
What is an important safety rule for transporting materials when using a ladder?
Never climb a ladder carrying material instead pull the material up after climbing
33
Self supporting scaffold
34
Manufactured Scaffold
35
Rolling Scaffolds
36
Inspecting Scaffolds
37
Scaffolds have to be tagged
- green safe to climb
- yellow usable, but use caution because it may be altered to complete a certain task
- red do not use because it's being put up or taken down
38
On equipment vehicles
- backup alarms must work
39
every 25 ft, if the trench is 4 feet, there has to be a ladder or stairs (some way) for going in and out
40
Trench box
Bench/slope (excavate at an angle, or make a set of stairs)
- protects workers as they work in a trench
- The trench box has to be above the excavation
41
Dirt being brought out
is called spoil
42
Type A soil
Cohesive soil that has a high unconfined compressive strength of 1.5 tons per square foot or greater. Examples: clay, silty clay, sandy clay, clay loam, and in some cases silty clay loam and sandy clay loam. Often used for gardening, farming, and construction projects that require a strong and stable foundation.
43
Type B soil
a soil that has medium stability and strength. It has an unconfined compressive strength of more than 0.5 tons per square foot (tsf) but less than 1.5 tsf. Examples: angular gravel, silt, silt loam, and some types of clay loam. Ofte n used for construction projects that do not require a very strong foundation.
44
Type C soil
least stable and productive soil. It has an unconfined compressive strength of 0.5 tons per square foot or less. Examples: gravel, sand, loamy sand, submerged soil, soil with seeping water, and unstable rock.
Not suitable for construction projects that require a strong foundation, and it poses a high risk of vace-ins or collapses in excavations.
45
Access and Egress
46
Soil has to be 2 ft from the edge of the trench
47
How many amps of current does it take to kill somebody?
less than 1 amp has the ability to kill somebody
48
Use a chord wiht a ground wire
pass through ground not through body
49
GFCI (ground fault circuit interrupter
trips before you get electrocuted
50
When should you work on an energized circuit?
never; always disconnect power first
51
Never use chords with cuts/revealed wire
must reinsulate the chord correctly in order to fix it.
