SOIL SAMPLING TEST

JOB SAFETY ANALYSIS (JSA)

Definition of Job Safety Analysis :

1) To identify the existing or potential hazards of specific tasks in order to reduce the risk of injury to workers.

2) Job Safety Analysis simply means looking at the work task and considering what is the safest way to complete it. It is a way of becoming aware of the hazards involved in doing the job and taking action to prevent an injury.

Who conduct the assessment of soil sampling :

1) Safety manager

2) Safety and health officer

3) Safety and health committee

4) Human resource department

5) Engineers

6) Supervisors

JOB ASSESSMENT PROCESS

b. Entanglement in a belt drive

c. Being struck by an uncontrolled spinning crank that is used to raise or lower the auger

Procedure :

Mechanical Auger :

1. The rig will be maneuvered into place and will either drill through an existing trial hole or directly through the surface.

4

2. Auger’s engineer will have removed the existing surface to excavate the trial hole or if this has not been done then prior to drilling they will remove the ground surface, this will involve either lifting slabs/paving or breaking through concrete, tarmac or similar.

3. The drilling is achieved by a mechanism consisting of a hydraulic drive with a chain driven drop weight that repeatedly strikes an anvil, driving the rods and sample tubes into the ground.

4. The tubes are brought up to the surface and contain a profile of the ground which can then be extracted, identified and described, they are typically split into 500mm sections are labelled and bagged for laboratory analysis.

5. Upon completing the borehole the engineer will backfill the hole and either re-lay the surface or reinstate a patch repair with new concrete/tarmac. It is important to note that patch repairs will not match the existing.

ELIMINATE OR CORRECT HAZARDS

Controlling hazard :

Accept hazard and reduce the risk.

Accept hazard and reduce the risk :

Mechanical Auger :

1. The rig will be maneuvered into place and will either drill through an existing trial hole or directly through the surface.

Engineering management :

Check that all guards are in place, properly secured, and functional. The guard surrounding the auger intake is critically important.

Replace all safety signs that are worn, missing, or illegible. Inspect winch and cable (or other lifting system) for condition, security, and

operation. If tractor operated ensure the grain auger is attached according to

manufacturer’s specification and confirm that PTO and all driveline components are in good condition and properly guarded.

Faulty equipment must not be used. Report suspect machinery immediately.

Administrative management : Training employees to recognize hazard and employ safety practices.

TRAINING REQUIREMENT

1 The rig will be maneuvered into place and will either drill through an existing trial hole or directly through the surface.

Installation of auger systems poses mechanical hazards due to the use of large rotating augers. During the in-situ stabilization process, heavy equipment and materials, such as augers are periodically raised overhead and placed into position. Workers may be exposed to swinging equipment or crushing hazards if the equipment were to fall.

A work zone should be established and only those personnel required to perform the task should be allowed in the zone.

Equipment should be raised only as high as needed.

Operators should avoid contact with auger edges, cables, and pipe

Hearing protection

Body wear

Glove

Protective footwear

Lifting equipment should be inspected regularly and operated safely.


Training employees to familiar with the handling of the auger.

2 Auger’s engineer will have removed the existing surface to excavate the trial hole or if this has not been done then prior to drilling they will remove the ground surface, this will involve either lifting slabs/paving or breaking through concrete, tarmac or similar.

During excavation and mixing operations(in-situ or ex-situ), workers may be exposed to inhalation/ingestion/dermal hazards from airborne contaminated dusts, volatile organic compounds (VOCs) and waste materials.

Eye exposure to airborne dusts and chemicals may occur, resulting in irritating, scratch and scarring of eyes. High-pressure injection of stabilizing compounds can spray or splatter chemical agents which may also cause eye damage.

The generation of airborne contaminants may be reduced by the periodic application of water to the active excavation and mixing areas.

Injection equipment should have pressure-trip interlocks to prevent operation at excessive pressures.

Air-purifying respirator equipped with approved filter/cartridges.

Eye protection

Faulty equipment must not be used.

Ensure all the safety equipment is in good condition.

Ensure all the employees know the standard operation of machine.

3 The drilling is achieved by a mechanism consisting of a hydraulic drive with a chain driven drop weight that repeatedly strikes an anvil, driving the rods and sample tubes into the ground.

Fire and explosion hazards may exist when using augers or other drilling methods if the auger contacts and/or ruptures underground utilities such as electric or gas lines or underground tanks may result in worker exposure to chemicals.

Identify the location of all below- and above-ground utilities prior to drilling.

Once utilities are located, careful excavation by backhoe

4 The tubes are brought up to the surface and contain a profile of the ground which can then be extracted, identified and described, they are typically split into 500mm sections are labelled and bagged for laboratory analysis.

During site activities, workers may be exposed to direct and indirect sunlight and the corresponding ultraviolet (UV)

Minimize direct sun exposure by wearing long-sleeve shirts and full-length pants, and by applying UV barrier sunscreen.

Using appropriate attire

Use head cover.

Rotating employees to reduce time and save energy.

Ensure the work runs smoothly.

radiation. Even short-term exposure to sunlight can cause burns and dermal damage. Exposure to hot and humid conditions may also result in heat stress, which can manifest itself as heat exhaustion and heat stroke.

Work and break areas should be shaded

Exposure to heat stress conditions can be minimized by taking frequent breaks, drinking adequate fluids, and performing work during the early morning and late afternoon hours.

5 Upon completing the borehole the engineer will backfill the hole and either re-lay the surface or reinstate a patch repair with new concrete/tarmac. It is important to note that patch repairs will not match the existing.

The employees may forget about the hole and trip over it. Result in injuries.
