Trench Safety Month is June! Trenching and excavation training should be provided to employees in order to comply with OSHA regulations and to learn about trenching hazards and how to reduce them.
Excavation and trenching are among the most hazardous construction operations. OSHA defines an excavation as any man-made cut, cavity, trench, or depression in the earth’s surface formed by earth removal. A trench is defined as a narrow underground excavation that is deeper than it is wide, and is no wider than 15 feet (4.5 meters).
There are many complex situation during work in excavation, fabrication, erection and testing are undertaken. The job hazards involves are present here.
This was in the book form circulated among the employees who works under project areas..
At present this book is not available. So it is given here for those working in SAL/ Bokaro Steel Plant for reference.
EXCAVATION AND PREVENTION OF HAZARDS.pptxEricShawd
Excavation refers to a man-made cut, trench, or depression created by earth removal.
Excavation is an integral part of many construction projects, including building foundations and public infrastructure projects like building roads.
Excavation sites present numerous hazards that can lead to serious injuries and death.
The major hazards include trench collapses, falls, falling objects, hazardous atmospheres, mobile equipment accidents, electrical hazards, and inclement weather.
This presentation aims to raise awareness about the hazards associated with excavation work and provide control measures to prevent accidents and ensure a safe working environment.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.
3. Basic defenitions
Deep Foundation means a foundation unit that
provides support for a building or structure by
transferring loads either by end bearing to soil or rock at
substantial depth below the building or structure, or by
adhesion or friction or both, in the soil or rock in which it
is placed, and includes a pile or caisson.
Excavation means a dug out area of ground and
includes a deep foundation excavation, trench, tunnel
and shaft.
Open excavation means an excavation in which the
width is greater than the depth, measured at the bottom.
4. Basic defenitions
Pile or Caisson means a slender, deep foundation
unit made of materials or a combination of
materials, such as wood, steel or concrete, which is
either pre-manufactured and placed by
driving, jacking, jetting or screwing, or cast in place in
a hole formed by driving, excavation or boring.
Shaft means a vertical or inclined opening that
leads to an underground working and is excavated
below ground level.
5. Basic defenitions
Shoring is an assembly of structural members
designed to prevent earth or material from
falling, sliding or rolling into an excavation.
Support structure means a temporary or
permanent structure or device designed to provide
protection to workers in an excavation, tunnel or shaft
from cave-ins, collapse, sliding or rolling materials
and includes shoring, bracing, piles, planks and trench
cages.
6. Basic defenitions
Trench means an excavation that is deeper than
its width measured at the bottom.
Trench Cage means a steel support structure
designed to resist the pressure from the walls of a
trench and capable of being moved as a unit.
Trench Jack means a screw or hydraulic jack used
as a brace for a temporary support structure.
Tunnel means a generally horizontal excavation
that is more than a metre long and located
underground.
7. MAJOR HAZADRS OF EXCAVATION
cave-ins or excavation collapses
excavated material
falling objects or objects near an excavation
powered mobile equipment
slips, trips, and falls
hazardous atmospheres
flooding/water hazards
underground facilities
8. Why do serious worker injuries and fatalities continue
to occur in the excavation industry?
It is because both employers and workers often forget
that when they remove earth from the ground it
creates an opening, and the remaining earth
surrounding the opening tends to relax. This
increases the pressure towards the walls of the
opening and makes the ground collapse. Water in the
soil or ground also affects the stability of the walls by
putting additional pressure on the walls and
increasing the possibility of a cave in. Unless a
horizontal distance equal to the vertical depth of the
excavation walls is maintained, engineering controls
must be used (ex: shoring, trench cages) to provide a
safe and healthy workplace within the
excavation area.
9. Falling Objects or Objects near an
Excavation???
Place tools and equipment used at the
excavation site so that they cannot fall into the
excavation or affect the structural stability of
the walls of the excavation. Use barriers to
help keep tools and equipment at a safe
distance from the edge of the excavation. Use
ropes or other lowering devices to transport
the tools or equipment into the excavation.
10. Excavated Material?
Injuries may also occur in excavation work when
excavated material on the surface of the excavation is
too close to the edge and falls into the excavation, or
affects the structural stability of the walls of the
excavation. Pile all excavated material so that the
material cannot roll back into the excavation. The
material must never be closer than one metre (three
feet) from the edge of the excavation, and should be
placed as far away as possible so it does not affect the
structural stability of the walls. Ideally, the excavated
material should be placed as far away from the edge of
the vertical excavation as the excavation's height.
11. Powered Mobile Equipment
Workers may be exposed to hazards when
powered mobile equipment is used near an
excavation site. Powered mobile equipment
includes backhoes, track hoes, concrete
trucks, trucks removing excavated material and
others.
12. COMMON HAZARDS OF PME
equipment placed close to the edge of an
excavation may cause the excavation walls to
become unstable. Powered mobile equipment can
be placed near the edge of the excavation if a
support structure, designed to consider the
overload from the equipment, is installed in the
excavation.
equipment vibration puts additional pressure on
excavation walls, affecting the structural stability.
13. COMMON HAZARDS OF PME
equipment operating on rough terrain, or too
close to the edge of an excavation, may roll over
and fall into the excavation. Ensure all equipment
is equipped with roll over protective structures
(ROPS).
workers riding on equipment without approved
seats may be injured
14. COMMON HAZARDS OF PME
workers getting on and off equipment are at risk
because balance can be affected by the vibration
of the equipment. A worker may not be as sure
footed getting off the equipment after operating
it for a period of time .
workers may be injured by equipment. A safe
distance must be maintained from moving
equipment at all times. Operators must be aware
of all workers near their work area.
15. Slips, Trips, and Falls
Slip, trip and fall hazards are common around
excavations. Examples include: excavation entrances
and exits. A safe means of entering and exiting an
excavation is required. Specifically, where an
excavation is more than 1.5 metres (five feet) deep, a
stairway, ramp or ladder is required. Workers must use
both hands when climbing up or down ladders. Tools
or equipment should not be carried up or down the
ladder.
16. Slips, Trips, and Falls
uneven ground surfaces around or inside an
excavation. It is important that a housekeeping
program is in place and every effort is made to
ensure walkways and pedestrian traffic areas are
maintained. excavation edges are a risk to people
working near them. employees working near the
edge of the excavation edge need to be protected
by a means of fall restraint or fall protection.
17. Slips, Trips, and Falls
walkways constructed for use over an excavation
must be built and maintained for safe use by
workers. Guardrails must also be in place so that a
worker cannot fall from the walkway into the
excavation. employees working around an
excavation site are at risk of falling into the
excavation. Adequate protection must be
provided for those workers as well as pedestrian
traffic that may come near the edge of the
excavation.
18. Hazardous Atmospheres
Hazardous atmospheres at excavation site may
come from soils that are moved or from pipes and
conduits disturbed during excavation. Where
there is a potential for a hazardous atmosphere, a
plan must be developed to ensure the workers in
or near the excavation are not at risk.
19. Hazardous Atmospheres
Pre-Work Testing – The atmosphere must be
tested before anyone enters the excavation to
ensure they won't be exposed to hazards.
Common atmospheric hazards include gasoline
vapours , methane or other explosive gases and a
lack of oxygen.
20. Hazardous Atmospheres
Controlling the Hazard – When an atmospheric
hazard is present, the first priorities must be to
eliminate or control both the hazard and entry to the
excavation. Ventilation must be installed, operated
and maintained to ensure worker protection. If
ventilation is not practical, the worker must be
provided with personal protective equipment suitable
to protect against the hazard. For
example, when there is a lack of oxygen, the worker
must be provided with an approved self-contained
breathing apparatus (SCBA) that provides adequate
oxygen.
21. Flooding/Water Hazards
Flooding – An excavation may flood if the work is
below the water table, near a watercourse bank or
exposed to adverse weather conditions. When
there is a risk of flooding, an emergency
evacuation plan must be developed. The plan will
include a full body harness with a lifeline to be
worn by workers in the excavation. Workers must
also have direct communication with the person
located at the surface of the excavation.
22. Flooding/Water Hazards
Water Accumulation – This may be caused by an
excavation near a ground water source, in wet
conditions or because of equipment that uses
water for operation near the excavation site.
Water accumulation must be kept to a minimum
to reduce risks such as slipping or tripping
hazards, electrical hazards, equipment
malfunctions or others.
23. Underground Facilities
Common underground facilities include:
electrical lines
oil and gas lines
telecommunication lines (phone, cable, computer)
water and sewer lines
traffic signal lines
steam lines
24. Underground Facilities
Special attention must be given to the hazards
associated with underground facilities. Before
beginning excavation work, proper planning must
identify the location of underground facilities
and any precautions needed to avoid contact with
these facilities.
25. Underground Facilities
To ensure that all hazards are identified, owners of
underground facilities must be notified prior to
starting excavation work. The owners of the
underground facilities must issue clearances or
specific instructions to the contractor. These
clearances. and instructions must be available on site
for further reference. If any pipe, conduit or cable that
is not supposed to be worked on is contacted during
excavation work, the workers must be immediately
evacuated from the excavation until all hazards or
unsafe conditions are identified and corrected. The
owner of the facility must also be notified. Special
consideration must also be given to prevent contact
with overhead electrical lines.
26. BEFORE YOU EXCAVATE
registered as an excavation contractor with the
Workplace Safety and Health Division
notified the Workplace Safety and Health
Division of your excavation and obtained a serial
number for your excavation
obtained clearances from underground facilities
obtained engineering approvals where required
provided appropriate training for all workers
involved in the excavation work
27. Requirement for Engineering
Approvals
the open excavation exceeds three metres (10 feet)
in depth, or the trench exceeds 4.5 metres (15 feet)
in depth.
a safety and health officer is of the opinion that a
temporary support structure may create a risk to
the safety and health of a worker, or there is a
change in the ground stability for which the
support structure was originally installed.
28. Requirement for Engineering
Approvals
the excavation may affect the structural integrity of a
nearby building, foundation, utility pole or other
structure.
an employer installs re-shoring.
where a worker is required to enter any deep
foundation excavation, including caissons and piles, a
professional engineer must provide approval on the
methods of entry and exit as well as the equipment
and methods to be used for hoisting.
29. Training for Workers
Employers must provide workers with information
and training on:
workplace hazards that they may encounter
safe work procedures developed to address those
hazards
devices or personal protective equipment required and
provided for their use
30. Training needs to take place
before workers perform work at the workplace
before workers perform a different work activity than
they were originally trained to perform
before workers are moved to another area of the
workplace or a different workplace that has different
facilities, procedures or hazards
