Welcome to SafeWork SA's tool box series
on avoiding utility strikes.
This series is all about avoiding utility strikes
while digging or working near overhead power lines.
This is the third episode, Excavation Work.
Excavation work can introduce
many high-risk work activities.
In this toolbox, we'll be looking at
excavating techniques to minimise those risks.
Excavations are any activities that penetrate the soil.
It could be as simple as using a shovel to dig a hole,
using an excavator to dig a trench,
or using a vacuum truck to remove soil.
Excavation work should be carefully planned
before work starts so it can be carried out safely.
Before starting any excavation activities,
you must take all reasonable steps to obtain
current underground essential services information,
and locate all services within the areas you are working.
Toolbox 1 and 2 explain this in more detail.
For all mechanical excavation activities,
it is good practice to use a permit to excavate,
as this will help clearly define persons
with key responsibilities, the scope of works,
preliminary planning requirements,
including permits from relevant authorities,
specific controls and hold points
with respect to identifying and locating services.
A permit to excavate helps work crews
understand the process.
A permit to excavate will need to be completed
by someone who has been trained
and deemed competent by your organisation.
However, everyone is responsible for making sure
that all steps on the permit
have been completed and are understood.
Excavation work can introduce
many high-risk construction work activities.
A documented SafeWork Method Statement
will need to be developed for those activities
identifying site specific hazards
and the appropriate risk controls.
The SWMS must also describe
how the control measures are to be implemented,
monitored and reviewed,
and should include what actions are required
in the event of contact with gas or electricity lines.
Prior to excavating,
ensure all relevant Personal Protective Equipment
is available on site, as identified in the SWMS.
When planning an excavation consider the following.
Have all access authorisations been confirmed?
Are there man-made structures?
Have overhead power lines been identified
if mechanical excavation or large plant is to be used?
Have all underground assets been physically located
and marked prior to breaking ground?
Have you notified all persons
who are affected by the work prior to commencing?
Will the planned trench be close
to pedestrian or vehicle traffic?
Is Work Zone Traffic Management required?
Barricading, cones and traffic control are examples of this.
Is the excavation going to be within a rail corridor?
If so has the appropriate authority been notified,
approved spotter engaged,
and the required rail safety induction undertaken?
Is there a risk of falling into the trench
during the day or night?
If so, consider covering or barricading the trench area.
Do exposed services need to be protected
from falling objects?
If the work is being performed on or near a country road,
give consideration to the level of compaction density
on the verge of the road,
as it may not be as solid as that on a major road.
How big will the trench need to be?
Can workers safely move around the site,
for example in and out of the trench,
and the movement of plant and equipment?
Are ladders required to assist workers
safely get in or out of the trench?
Consider an emergency situation
where you needed to rescue a worker from the trench.
Plan how you would get them out.
If the excavation is greater than 1.5 metres deep,
you must install trench support,
shoring, battering, or benching.
What equipment will be in use?
If it is needed in the trench
how will you get the tools and equipment in and out?
How long will trench be open for?
The longer it is exposed to the elements,
the greater the risk of collapse.
All open excavations and assets
shall be secured in a safe manner
when there are no workers on site.
Operators of excavators and backhoes
must be trained and competent
prior to operating any machinery on site.
If mobile plant is in use,
ensure all workers remain outside
the operator's blind spots.
Operators can often have
severely restricted visibility
of ground workers or nearby pedestrians,
particularly those close to the plant.
Consider the placement of the spoil.
Where possible, place it on the low side
or opposite to previous excavation
at least 1 meter from the zone of influence.
Consider heavy fleet accessing the site;
all need space planning, safe bringing to site,
use, and removal.
Also consider possible weight effects on trench sides.
Heavy loads should not be located
in the zone of influence of an excavation,
unless the ground support system installed
has been designed by a competent person,
for example, a geotechnical engineer, to carry such loads.
The zone of influence will depend on the ground conditions.
It is the zone in which there may be an influence
on the excavation, including possible ground collapse.
Some soils are more stable than others.
The type of soil is one of the factors
that determine the chance that an excavation may cave in.
Hard cohesive is very stable.
Clay is an example of a hard cohesive material.
Soft cohesive is less stable.
This generally includes crushed rock, silt,
and soils containing an equal mixture of sand
and can incorporate silt material.
Non cohesive is even less cohesive.
Gravel and coarse sand are examples.
Consider the soil's granularity.
This refers to the size of the soil grains;
the larger the grains, the less stable the soil.
For example, clay has very small grains.
Saturation means how much water soil will absorb.
Saturated soils are subject to slumping.
Cohesiveness means how well soil holds together.
Remember, clay is a cohesive soil.
When adjoining man-made structures,
all soil types will lose their normal cohesiveness.
They will not bond to man-made materials
like concrete, brick and metal.
Also man-made structures
may introduce a large downward force on the soil below.
For this reason, excavating near man-made structures
requires special safety consideration.
Normal battering and benching designs
may have to be revised around man-made structures.
More soil removal may be required.
If in doubt seek professional engineering advice.
So, in summary:
Conduct appropriate searches
for overhead and underground utilities.
Where high risk construction work has been identified,
complete a documented SWMS based on a risk assessment
and consider a permit to excavate process.
Notify the public and protect them
from machinery and fall hazards.
Consider traffic management.
Consider the proximity of machinery to workers
and the sides of the trench.
Machinery operators must have
the appropriate training and competency.
Consider trench depth and size.
Workers need to enter and exit the trench safely
and must have the appropriate
personal protective equipment and tools.
Is the trench at risk of collapse?
Conduct analysis of soil type
and length of exposure to the elements.
Support the trench appropriately.
Practice emergency procedures regularly.
Toolbox 4 of the series
outlines the safe approach limits for people
and minimum safe clearance distances for machinery
when working near overhead power lines.

Ant Man and the Wasp Casts Sean Kleier in Key Role - Duration: 3:12.
the cast of Ant Man and the wasp continues to grow with Sean kleiner
joining the film the sequel to 2015's debut outing for the shrinking superhero
is going to be the MCS first film after Avengers infinity war so will naturally
be of a fittingly smaller scale although that doesn't mean it's not being more
ambitious than the original indeed the film has already vastly expanded its
cast as well as Michael Douglas Michael Pena and Judy Greer returning to backup
Paul Rudd and Evangeline Lilly Steeler heroes there are high-profile additions
including Michelle Pfeiffer as the original wasp Walton Goggins as Sonny
birch Laurence Fishburne as Goliath and Randall Park as Jimmy woo although the
film is already well into principal photography production another key
player has reportedly been added the hashtag show reports that Sean Klein has
been cast in ant-man in the wasp in what they describe an apipa ttle currently
unnamed role character details are scarce but he's said to be a special
agent and mo lova story Kleier has become a semi prominent TV comedy actor
in recent years best known for starring in odd mom out but also having recurring
roles in happy-ish and mr. right this would seem to suggest in his first major
blockbuster role he's had minor parts in just a few movies he would be in a
comedic part although given how the ant-man side of the MCU tends to be
lighter in tone than some other areas in general and that vague description there
may be something more indeed special agents are recurring presence in rumors
surrounding the film with Jimmy woo heralding the return of shield to the
big screen and the synopsis teasing the likelihood of a similar heist adventure
the fact he's called a mole could work either way is he a secret villain or a
good guy getting close to the movies actual Big Bad presumably Hannah John
commands Ghost th s DRI CIA Special Agent Jeffrey
Ballard who in the comics became villains and Tyrion but that's just
speculation for now of course casting at this point cameras started rolling at
the start of this month can often mean a minor role although it all really
depends on the shooting schedule there's been several lots of set photos emerged
from the production so we might get some more tangible clue soon

► Diamond Sky - Elliot Berger (Ft. Laura Brehm) | Sub Español - Duration: 4:09.
Moving with the wind
We are free fallin now
No choice but to trust this
As we
go into
the void
We are standing
Staring into empty space
Asking all our questions
Answers we can't chase
Is this all there is?
Is this all there is?
I feel the wave
of the change
Reflect on
everything
we know
How do you stand
Out from the infinite
The rate of growth
Is hard to keep up with
Under a diamond sky
Everyone wants to shine
Under a diamond sky
Everyone wants to shine
We are all connected
To each other now
Reaching new dimensions
As we
go into
the void
Moments away from our
one true destiny
Time won't slow down at all
Like a bird
set free
It will fly
to
the
heights
Of it's whole life
Do not hesitate
in flight
Just reach the sky
I feel the wave
of the change
Reflect on
everything
we know
And can we stand
Out from the infinite
We are the ones
who define what this life is
Under a diamond sky
Everything starts to shine

How to be Creative ? - Duration: 2:57.
are you creatively blocked ? Julia Cameron -the author of the book ' the artists way'
which is a staple on creatively mentions, "that jealousy is an excellent clue to
judge if you're blocked." If there are people who use or resent or if you tell
yourself I could do that if only ... and your brain somehow comes up with a bunch
of reasons for why /// excuses. Do you ever tell yourself that if only you took your
creative potential seriously you might be able to accomplish many great things?
We should all be creative !!! Why ? Brenda Ueland - a prolific teacher of
writer, journalist, editor and a scriptwriter for radio shows in the
early 1900's - mid 1900's said, -"we should all
be creative because there is nothing that makes people so generous, joyful,
lively, bold and compassionate. So indifferent to fighting and the
accumulation of objects and money. It would lead to a lot less frustration in
the world. She also said, that "everybody is talented and
creative because everybody who is human has something to express. Where do I Begin?
STEAL!!!! That's right ! STEAL things from
people. A world renowned artist of the 20th century named Pablo Picasso said
that -"Art is the theft." David Bowie - a pop singer, songwriter, and actor who
produced 11 -#1 albums over his career was quoted saying that, "The only art I'll
ever study is the one that I can steal from."
Yohji Yamamoto an influential Japanese fashion designer and a master tailor said,
"Start copying what you love. Copy copy copy, because at the end of the copy you
will find yourself. and the last quote from one of my favourite basketball players of
ALL time said, "I have stolen all these moves from great players. I just
try to do them proud. The guys have come before me because I learned so much from them.
It's all in the name of the game. It's a lot bigger than me...........
GUYYYYSSSS!!!!!! I have pinkeye and it's
disgusting. I feel so sad ! So... what is creativity ? As mentioned in the book
"Thinking Grow Rich"- Napoleon Hill. There are 2 forms of creativity -
1. Synthetic imagination and 2. Creative imagination Synthetic imagination is
old concepts + ideas + plans = new combinations. Creative
imagination is through which hunches and inspirations are received from higher
thought frequency processes. So basically in the beginning you start with
Synthetic imagination to learn and get in that higher frequency of thought.
But then later on you transition to ----> Creative imagination which is exactly what
happened with any creator. At first you emulate and then from there you find your """""" OWN. """""

Right After Pardoning Joe Arpaio, Trump Just Did Something HUGE For Sheriff David Clarke - Duration: 1:37.
Donald Trump may be President now and working hard to try and put our country back together
with his time in office, but that does NOT mean he forgets the people who got him there.
Just last week the President issued a Pardon to Joe Arpaio, a retired Sheriff accused of
violating a court order.
Today, he gave a special gift to another cop buddy of his, Sheriff David Clarke…
President Trump told everyone how good Sheriff Clarke's new book "Cop Under Fire: Moving
Beyond Hashtags of Race, Crime, and Politics for a Better America"
The President Tweeted,
"A great book by a great guy, highly recommend."
Lefties HATE Sheriff Clarke, mainly because he is a conservative black cop.
He also has driven them crazy by going after BLM, Antifa, and other leftists hate organizations.
If you were not already aware, Clarke also was one of the FIRST people to defend Trump's
response to Charlottesville.
He saw it for what it really was: a declaration that our country will not tolerate hate on
either side.
Sheriff Clarke is a man who simply has dedicated his life to upholding law and order and there
is nothing wrong with supporting a hero like this.
Help the good man out by sharing this out and, if you are a reader, buy his new book.
It comes highly recommended by the President of the United States, after all.

【初音ミク】Reassessment (MARETU) ~English Subtitles~ - Duration: 4:09.
I believed in a lie, believed in it
When I realized it, when I realized it,
It was far too late to stop
It was such a dark heart, just leave it alone
I understood, I understood
To say it was past time to get over it
Ah, such a child to be born of his
To be so miserable and despised
I know it'd fail to reject such an idea
A dead love
My baby girl's rusted maidenhead
I remember thinking it unneeded
All that is left is the role of regenerating slavery
That is just life
Please, keep this ring
I'm going to destroy this world,
Heart
and body
Those countless worries you have
Abandon this dumb idol
Get caught up in this entangled situation
Coldly
Rightly
Cut it out, my confused partner
How to disappoint you, who was already
born regrettably
There are still destinations left
for us to see.
More so, the tears will wither away
So, let's give up already
So, let's be happy
Ah, I see.
A lie looked out, greedily looked out
When I realized it, when I realized it,
The end of this dream is close, yet,
Do not mention anything about that dark heart
I understood, I understood
The sinful crime is coming to a near
I was born in such an unacceptable way
My nausea kept chase at me
I know this is but a denial of failure
A dysfunctional love
My baby girl's rusted maidenhead
You can see this as going downhill
Let's make things come true, I don't want to see any
"I don't wanna be born."
Please, keep this ring
I'm going to destroy this world,
Heart
and body
Those countless worries you have
Escape this circumstance
Let's create complex emotions
With this hand
With these eyes
This mass of sculpted insights
Repetitive
Self criticism, dangerous thoughts
Residue of natural love
Now, an innocent, awkward defeat should be obvious
A delusional birth, believing that only "living is everything"!
And,
Reproduction of slaves, that's just life
A strange pleasure we get just from removing safety
The next spoiled victim fills this room with unneeded words
Maybe this feeling will only be understood with a taste, and after this
Maybe this pain will also only be understood with a taste, and after this
It was only funny when I had to hold in my laughter,
when was that?
I'm being cluttered by
gathering memories!
Both sides of this were damp, were damp
Let us break away from what has already ended
To you that were completely born,
even if it was with struggle
Because only you can choose the unclear path
of your life.
More so, the tears will wither away
Without hesitation, let us set out
Shall you be born again?
So, let us be happy
There is not a thing wrong with you.

Cheryl and Liam Payne look smitten as they share first holiday pictures since birth of baby Bear
Cheryl and Liam Payne look smitten as they share first holiday snaps since birth of Bear. Cheryl Cole and Liam Payne couldnt look any happier as they shared snaps from their first family holiday since the birth of their son Bear.
Liam and Cheryl, 34, headed off on holiday to catch some sun ahead of Liams 24th birthday – and now the Fight For This Love singer has posted their enviable pics on Instagram.
Its the first outing proper for the loved up couple and their first family excursion since their son was born.
Cheryl looked at ease as she posed on a boat for one of the pictures, displaying her figure just five months after welcoming Baby Bear to the fold in March.
The couple also posted a series of selfies to Instagram Stories, showing that the former Girls Aloud star was fresh and happy since returning to social media.
Some of the pictures showed the lovebirds clearly having fun on their holiday with filters and emojis. One of the Instagram posts shows Liam putting his arms around Cheryl and stroking her hair in an image that resembles a Calvin Klein advert.
Cheryl and Liam Payne look smitten as they share first holiday snaps since birth of Bear. Another showed the couple naturally beaming with happiness as they basked in the sun.
Its not the first display of PDA to come from camp Chiam – with Cheryl sharing a picture of the couple as she plans to record a new album in the US.
'Couple goals' was the general consensus of her fans, as was how beautiful a couple they make – all we need now is a cute selfie with little lad Bear to tip us all over the edge.
It's a sweet insight into their personal lives, and not because the 34-year-old has an album to promote or anything. Hang on a minute – its been rumoured the popstar is planning on her comeback with her fifth solo album, what timing.
She reportedly has designs on recording it during their trips to LA – she was recently seen picking up her American visa to put the plan into action. So this album may well not be too far off.
A source told The Sun: 'Cheryl's got a longer US visa so she can go back and forth more frequently to the States. 'She hasn't started working on the new album yet as she is still enjoying her time off with Bear.
So… what else has been happening with team Chiam? Liam surprised Londoners earlier this month when he appeared busking on Oxford Street and performed new single Get Low.
The Strip That Down singer was spotted singing at various locations around the capital on Tuesday, including outside the National Gallery at Trafalgar Square, armed with a mic and his DJ collaborator Zedd, who features on the track.
Liam Paynes been doing impromptu performances on the streets of London. And finally – Liam confirmed that a One Direction reunion will be inevitable. We cant wait to see if it happens.
In a candid chat with Buzzfeed, he revealed: 'I think we will reunite at some point in the future. 'We've got an album we haven't even toured yet. And I want to write some more songs as well with the boys.'.
