Industrial tank cleaning services provided by McRae’s Environmental is one of many services that we provide to various industries in the lower mainland. These services ensure the proper functioning, maintenance, and safety of tanks used for storing liquids, chemicals, or other materials. Over time these tanks can accumulate residues, sediments, and contaminants leading to potential corrosion, reduced efficiency, and potential safety hazards. Cleaning these tanks is essential to maintain operational integrity, prevent contamination, and comply with regulatory provincial standards. Below are the key aspects of industrial tank cleaning:

Tank Assessment:

  • Before cleaning, we assess the type of tank, the material it contains, and the extent of contamination. This information helps our team choose the right type of vacuum tanker, the right equipment, and the cleaning method.

Safety Precautions:

  • Prioritize safety during the cleaning process. Tanks may contain hazardous materials or fluids, so it’s essential to follow proper safety protocols and provide our workers with the appropriate PPE.

Isolation and Draining:

  • Isolate the tank from the process to prevent any unwanted flow of materials or liquids. Drain the tank completely to prepare for the cleaning process.


  • Ensure proper ventilation to disperse any fumes or vapors that may be released during the cleaning process. This is crucial especially when dealing with potentially harmful substances.

Cleaning Methods:

  • Manual Cleaning: This involves physically entering the tank with a confined space entrant to scrub and remove debris before washing. However, this method is labor-intensive and requires proper safety measures.
  • Mechanical Cleaning: Use of tools such as pressure washers, brushes, or scrapers to remove deposits without the need for confined space entrants.
  • Chemical Cleaning: Involves using specialized cleaning agents to break down and remove contaminants before vacuuming.
  • Automated Cleaning Systems: Robotic or remotely operated systems can be used for cleaning tanks without human entry, reducing safety risks.

Waste Disposal:

  • Properly manage and dispose of the waste generated during the cleaning process. Follow environmental regulations and guidelines set out by both federal and provincial governments for the disposal of contaminated waste.

Tank Inspection:

  • After cleaning, inspect the tank to ensure that all residues have been removed, and the tank is in good condition. This may involve using inspection tools such as cameras, or other technology.


  • Maintain detailed records of the cleaning process, including the methods used, any issues identified, and the personnel involved. This documentation is essential for regulatory compliance and future reference.

Regulatory Compliance:

  • Adhere to industry standards and regulatory requirements governing tank cleaning processes. Compliance ensures the safety of all workers, environmental protection, and overall operational integrity.

Regular Maintenance:

Implement a regular tank maintenance schedule to prevent excessive build-up of contaminants and ensure the continued efficiency of the tank or tanks. In summary, industrial tank cleaning is a specialized field that requires expertise in handling various substances, understanding safety protocols, and complying with relevant regulations. Professional tank cleaning services or specialized equipment may be employed to ensure thorough and safe cleaning processes.
