Excavation Safety-PowerPoint

Evacuation and its Types

What is Construction Evacuation, and how many types of Excavations Are?

Excavation is the mechanism of moving earth, rock or other materials with hand tools, equipment, heavy machinery or explosives. It encompasses various earthwork, deep trenching, wall shafts, tunneling and underground. Excavation has various essential purposes including exploration (mines & natural), environmental restoration, construction. Among all of the above mentioned, construction is one of the most frequent functions for excavation. Excavation is utilized in construction field to create building foundations, reservoirs and roads structures.

  1. Topsoil excavation
  2. Earth excavation
  3. Rock excavation
  4. Muck excavation
  5. Unclassified excavation

Both excavation and trenching are among the most hazardous and fatal construction operations. As per Occupational Safety and Health Administration (OSHA) definition, an excavation is as man-made cut, cavity, trench, or depression in the earth's surface made by earth removal light and heavy machinery and tools.

The absolute excavation mechanism includes:

  1. Setting out corner benchmarks
  2. Surveying ground and top levels
  3. Excavation to the approved depth
  4. Dressing the loose soil
  5. Making up to cut off level
  6. The composition or construction of dewatering wells and interconnecting trenches
  7. Making boundaries of the building
  8. The construction of protection bunds and drains

Safe Rigging Practices

Authorized, Competent and Qualified worker or employee carries out rigging must always take care of attention to details very carefully and closely. Single Safety negligence, careless moment or act can result in serious injury or fatal death and huge financial destruction. Appropriate rigging is a skill and should never be left to the inexperienced personals. If you don’t know how to do it properly and safely, then don’t try it.

Definitions

Balanced – load equally distributed on each side of the point of support.

Breaking Strength – the comparative key point, when under the maximum quantity of load, the load handling device failure.

Bridle Sling – A sling combination of various legs reunited in a fitting that goes over the lifting hook.

Competent Person – Hired, appointed or assigned by the employer as being competent, skilled to perform a particular job.

The Factor of Safety – the ratio of breaking strength to the force to be practised. 

Hitch “Basket” – this term refers to the loading with the sling passed under the load and both ends on the hook or a single master link.

Hitch “Choker” – this essential term in rigging operation refers to the loading with the sling passed through one eye and suspended by the other.

Hitch “Vertical” – this term refers to - loaded with the load suspended vertically on a single part or leg of the sling.

Master link – a steel link or ring utilized to support and strengthens all legs of a chain or wire rope sling.

Mousing – This term in rigging operation is about lashing between the neck and the tip of a hook to prevent the load coming off.

Rated Capacity – the maximum amount of Allowable Working Load (AWL).

Rigging – This term in rigging refers to the connection of a load to a source of power so that it can be lifted and moved securely and predictably without any serious occurrences.

Safe Working Load (SWL) – the maximum PERMITABLE working load well established by the manufacturer.

Sheave – a wheel with an engraved circumference over which a rope is bent.

Wire Rope – consists of various individual wires INSTALLED or LAID into various strands which are in turn, laid around a centre core.

The Importance of Safety Signs and their Color Codes

Implementing each and every organization’s successful and positive workplace health and safety policies often depends on severe reading, instruction and learning on the part of employees, with the most dangerous professions requiring critical internal & external training programmes before the work can be accomplished safely. In this situation, the influence of health and safety signs lies in their capability to communicate the most integral and vital HSE messages in a way that’s visual, catchy, immediate and precisely targeted.

Health and Safety signs feature apparently pictographic illustrations of the hazard they’re pin pointing, followed by clear, simple text instructions, attractive, colorful and an eye-catching visual design. They are also appropriately colour-coded and shaped significantly to make it noticeable & access able at a glance when a worker is entering a high-risk area, or when there are actions, they require to take in order to make sure the safety of themselves, and other members of the society.

Generally, Health and Safety signs are not intended as a replacement for comprehensive safety training, but they are an integral portion in HSE policy, providing clear reminders of the most critical health and safety messages in the places they are most required. In most dangerous and high-risk workplaces where many staff members are from various nationalities and having difficulties in communication and may not speak English as a first language - or where the working environment is loud enough that verbal warnings might be missed - the importance of clear visual communication of this kind cannot be underestimated.

The Health and Safety Signs have the following importance if we look it in short:

  1. Instant visual communication of key safety messages
  2. Highlighting safe methods of work as well as hazards
  3. Legal requirements
  4. Protecting employees and the public alike
  5. Better safety benefits everyone

  • Workers

Instructions for Completing the JSA Form 

Job Safety Analysis is an essential incident prevention tool that is utilized by finding hazards and eliminating or minimizing them before the job is performed, and before they have a chance to become accidents. Use Job Safety Analysis for job scope, clarification, hazard awareness acknowledgement, as a guiding note in new worker’s HSE training & induction, for the specific duration of contacts and retraining of senior workers, as a refresher on jobs which run occasionally, as an incident investigation tool, and for informing employees of specific job hazards and protective measures.

Set priorities for doing Job Safety Analysis JSA’s: jobs tasks that have a history of many minor or fatal accidents, jobs that have caused disabling fatal injuries, jobs with the high potential ratio for disabling injury of death, and new jobs with no accident history.

Select a job to be analyzed. Before filling out this form, consider the following:

The Purpose of the Job-Activity Include:

  • What has to be done? 
  • Who has to do it? 

The Activities Involved: 

  • How is it done? 
  • When is it done? 
  • Where is it done?

In short, to accomplish this Job Safety Analysis form you should consider the purpose of the job, the activities it involves in that job, and the hazards its presents. If you are not familiar with that particular job, interview a worker who is. Besides, observing a worker’s performing the job, or “walking through” the operation step may give extra penetration into potential hazards. Here’s how to do each of the three parts of Job Safety Analysis (JSA)

  • Unauthorized entry
  • Damage hose
  • Overpressure
  • Personnel injury
  • Property damage
  • High-pressure leaks
  • Damaged test pressure gauges,
  • Test pump,
  • Blinds,
  • Flanges,
  • High-pressure hoses, gaskets & connections.
  • Leading to sudden failure and discharge of parts of the system
  • Filling & Dewatering from pipelines

Hydro Test Formula: (0.15) x (D) x (a) ^ 0.4 x (p) ^ 0.6

D: Internal diameter
A: Length/diameter of a piece (m)
P: Test pressure (Bar)

Knowledge Point:

  1. Hydro test periods: steel tank should be every 5 years, fiber
  2. wrapped every 3 or 5 years (depending on DOT-E regulatory if
  3. unsure shall be every 3 years)

Why is Nitrogen Used for Pressure Testing?

The two main areas of Nitrogen gas are used within Heating, ventilation, and air conditioning (HVAC) are for brazing and pressure testing copper coil. Nitrogen [N2] is used during the brazing process to purge oxygen O₂ from the brazed surface. Nitrogen [N2] also prevents the formation of moisture during the leak testing process, thereby eliminating oxidation of the metal

Heat Stress-Thermal Work Limit (TWL)

What Thermal Work Limit term mean?

TWL is explained as the limiting or maximizing renewable metabolic rate that well-hydrated, acclimatized individuals can maintain in a particular thermal environment, within a safe deep body bottom-line temperature (< 38.2 °C or 100.8 °F) and Sweat Rate (SR) (< 1.2 kilograms or 2.6 lb per hrs.) The index is made for self-paced employees and does not rely on the estimation of real-time metabolic rates, a process that is difficult and subject to considerable error. The index has been introduced into Australia, resulting in a considerable and consistent fall in the incidence of heat illness in the latter.

Thermal Work Limit (TWL):

  1. Enable safe management of work in the heat
  2. Measured in watts per square meter (w/m2)
  3. Calculated from environmental parameters
  4. Employee hydrated & acclimatized to the conditions

TWL Measured in / Readings:

  1. WBGT: Wet Bulb Globe Temperature
  2. TWL: Thermal work limit (w/m2) watts per minute
  3. WORLD Temperature: c’ (decisive by the Radiant Heat-RH) (in degrees °C)
  4. Dry Bulb Temperature (DBT): c’ (ambient air temperature) (in degrees °C)
  5. RELATIVE HUMIDITY (RH):  % WET Bulb Temperature: c’ (determined by the humidity/evaporation) (in degrees °C)
  6. WIND: m/s (in meters per second)

Knowledge Point:

  1. Headaches do happen with little fluid loss (1-2 litres).
  2. Sweat is 99.9% water so change it with water.
  3. Heat Exhaustion greater than 40.6 c’
  4. Sweat Rates (SR) can be up to 1.5 litres/hour

Symptoms of Heat Stress

  • Headache, Dizziness, Weakness, Nausea, Fainting, Colored urine, Inability to think straight, mantel confusion, upset stomach, Clammy skin, moist skin, Mood change such as irritability or confusion, hot dry skin, red skin
  • If you find these types of symptoms immediately take medical help otherwise it may be
  • Dangerous for individual life
  • Workers/employees/people can take precautionary measures to avoid heat stress.

Log Out-Tag Out (LOTO)

What is Lock Out?

Lock out is the process of preventing the flow of energy from a power source to a piece of equipment & keeping it from operating. Lock out is accomplished by installing a lock out device at the power source that equipment powered by that source can’t be operated. A lock out device is a lock, block or chain that keeps a switch, valve or lever in the off position. This is a special lock using for lock out only.

What is Tag Out?

Tag out is practiced by placing a tag on the power/energy source. The tag acts as a warning not restore energy. It is not a physical restriction tags must clearly state DO NOT OPERATE or the like & must be applied by hand.

What is Blinding?

The insert of a blind, spade or spectacle plate, the location of which is specified on an official blind list. Valve closed, isolating the system, put the blind

What is Isolation?

  1. To remove energy either mechanical or electrical e.g. blinding or disconnection
  2. To separate energy either electrical or mechanical 
  3. Positive isolation: means all energy sources to be identified all energy sources must be isolated and residual energy must be eliminated

Kinds of Blinds:

  1. Slip blind
  2. Ring blind 
  3. Spectacle blind,
  4. Flange blind

Safe Isolation:

Stoppage, draining down and blanking the systems during a shutdown assured by:

It is a decisive for the safety of maintenance staff that services are stopped, drained down, blanked etc. and remain in a safe status for the duration of the work

Knowledge Point:

  • Radiation energy, stored energy may be contained.
  • Cable steel/ car steel: flexible wire locks Red for closed and Green for open.
  • Pro lock. Universal system color red and green shall be used with conjunction with tag.
  • Residual stored energy: stored energy may be contained. Available some energy to harm.
  • Group lock out box: used to electrical breakers where can hold only one lock and others locks shall be in group lockout box which is available beside the panel.
  • Above 650 v Isolate and De-isolates done by SAEP (senior authorized electrical person).
