Step 1: Inspection


Fiberglass tanks are an essential component in many industrial settings, but they can be susceptible to failure due to a variety of reasons, including chemical attack, nozzle failure, penetration failure from manufacturer's stock designs, and impact damage from falling equipment or tools. Regular inspection is crucial to ensure the integrity and longevity of these tanks.


Step 1A: Exterior Inspection

  • Begin by inspecting the entire tank exterior, including ladders, handrails, midrails, toe rails, flanges, nozzles, manway doors, pipes, pipe supports, and tank anchoring.

  • Look for any signs of damage or wear, such as corrosion, cracks, crazing, deformation, insulation failures, paint failures, and pitting.

  • Document any issues found and take note of their location for future reference.


Step 1B: Tank Supports

  • Inspect the tank supports/feet and tank support pad/floor supporting the tank for signs of corrosion and/or deformation.

  • Note the condition of the supports and any issues that may need attention.

Step 1C: Tank Identification

  • Inspect the tank identification signs and the NFPA Hazard Identification Sign.

  • Identify and document any damage or if a sign is no longer legible.

Step 1D: Interior Inspection

  • Inspect the tank interior for air bubbles, blisters, burned areas, chips, cracks, crazing, deformations, delamination, dry spots, edge delamination, foreign inclusions, pitting, scratches, surface pinholes, wrinkles.

  • Take note of any areas that appear damaged or worn and document their location for future reference.

Step 1E: Tank Tests

  • Perform additional scanning and tests to determine chemical permeations, degraded areas, thin coverage areas, tank thickness, or overlapping of corrosion barrier resin.

  • A Barcol hardness test should also be performed at random areas of the tank interior to evaluate the condition of the corrosion barrier.

Step 1F: Tank Manway Gaskets

  • As part of the inspection, it's essential to remove and replace the manway gasket after the Inspection or Repairs, and if Repairs are required, they should be authorized by the Owner.

  • New manway gaskets should be fabricated or repaired.

It is essential to keep in mind that the tank owner should authorize any and all repairs. A detailed report should be provided after the inspection and any necessary repairs outlining the tank's condition, any issues found, and the steps are taken to repair them. This report will also include any recommendations for future maintenance or repairs. Regular maintenance and inspection of Fiberglass tanks are crucial to ensure they remain in optimal condition and to prevent costly repairs in the future.


Step 2: Safety


When working on a fiberglass tank, it is essential to follow strict safety protocols to ensure the safety of all involved. It is important to be knowledgeable about reference materials published by organizations such as API, NFPA, NIOSH, and OSHA and to have a clear understanding of the potential hazards associated with the materials stored in the tank. This includes the potential for toxic fumes and lack of oxygen, as well as fire and explosion hazards.


To ensure the safety of all involved, it is crucial to take the following steps:


  1. Obtain and review the applicable Material Safety Data Sheets (MSDS) for any material stored in the tank before entering.

  2. Ensure that proper ventilation and oxygen levels are maintained at all times. Safe levels of oxygen range from 19.5% to 20.1%.

  3. Inspect the tank for any potential fire or explosion hazards and take the necessary precautions.

  4. Wear the appropriate personal protective equipment (PPE) such as respirators, goggles, and protective clothing.

  5. Develop an emergency response plan and ensure that all individuals involved are trained on it.

  6. Have the necessary safety equipment on hand, including fire extinguishers, gas detectors, and emergency exit routes.

  7. Regularly check and maintain all safety equipment to ensure it is in proper working order.

  8. Follow all OSHA standards and regulations pertaining to confined space entry.


By following these steps and adhering to the guidelines set forth by the relevant organizations, we can ensure the safety of all involved during the fiberglass tank inspection process. At PlasTech Services, Inc., we prioritize safety and take all necessary precautions to ensure the safety of our team and our clients.


Step 3: Report


After the inspection and necessary repairs, it is crucial to provide a detailed report to the plant owner outlining the condition of the tank, any issues found, and the steps taken to repair them. This report should be clear and easy to understand, with detailed descriptions and photos of any issues found. It should also include any recommendations for future maintenance or repairs.


To ensure that the report is accurate and complete, it is important to follow these steps:

  1. Take detailed notes and photos of any issues found during the inspection.

  2. Clearly document the location and extent of any damage or wear.

  3. Provide a summary of the steps taken to repair any issues found.

  4. Include any relevant test results, such as Barcol hardness test results.

  5. Provide recommendations for future maintenance or repairs, including a schedule for regular inspections.

  6. Make sure the report is written in plain language and easy to understand.

  7. Review and double-check the report before sending it to the plant owner.

By following these steps, the inspection report will be a valuable tool for the plant owner, helping them to understand the condition of the tank and any necessary repairs. It will also provide them with the information they need to make informed decisions about future maintenance and repairs. At PlasTech Services, Inc., we understand the importance of accurate and clear reporting, and we strive to provide our clients with the information they need to keep their tanks in optimal condition.


Step 4: Drain and Flush the Tank

Before the tank is put back into service, it is essential to drain and flush it thoroughly to remove any debris or residue that may have accumulated during the inspection process. This will help to ensure that the tank is clean and ready for use and to prevent any potential contamination of the materials stored in the tank.


To properly drain and flush the tank, it is essential to follow these steps:

  1. Drain the tank of any remaining materials or fluids.

  2. Flush the tank with water or a suitable cleaning solution to remove any debris or residue.

  3. Inspect the tank interior to ensure that it is clean and free of debris.

  4. Repeat the flushing process if necessary.

  5. Use appropriate cleaning methods for the type of material stored in the tank.

  6. Dispose of any materials or cleaning solutions in accordance with local regulations.

  7. Test the tank for any leaks or damage before putting it back into service.


It is important to note that not all tanks require draining and flushing as some tanks may be self-draining, but in the cases where it is needed, it is essential to follow proper procedures to ensure the safety of the workers and the quality of the materials stored in the tank. At PlasTech Services, Inc., we prioritize safety and the quality of our work and we will ensure that the tank is drained and flushed properly before putting it back into service.
