Inspection and Technical Services - Steam and Pressure Plants

The Steam and Pressure Plants Act and The Power Engineers Act together to establish a safety partnership among those who use, design, construct, install, repair, and inspect pressure equipment. The Office of the Fire Commissioner works with equipment owners, manufacturers, installers, licenced power engineers and pressure welders to ensure that all are meeting their obligation to safety.

All repairs and alterations to boilers and pressure vessels must be reported Inspection and Technical Services using the following form.

There are several Pressure Equipment Programs including:

  • Pressure Equipment Inspections Program
  • Certificate of Authorization Program (Quality Control Certification)
  • Design Registration Program
  • Power Engineer Training, Examinations and Licencing Program
  • Welding Testing Program

Guarded Status information and Requirements for Owners and Operators of Steam Plants

Guarded Status Information and Requirements for Owners and Operators of Refrigeration Plants


Periodic government inspection and certification is the keystone of the province's pressure equipment safety program. Under the Act:

  • No boiler or pressure vessel may be operated without a valid inspection certificate issued by Inspection and Technical Services. Certain refrigeration plants also require certification, depending on type, size and refrigerant.
  • A valid inspection certificate is issued only after a Inspection and Technical Services Inspector has conducted an inspection of the plant or equipment and found it to be in satisfactory condition.
  • Inspection certificates for most boilers are issued for one year; annual inspection is required to renew the certificate each year.
  • Inspection certificates for most unfired pressure vessels are issued for two years; inspection is required once every two years to renew the certificate.

Scope of the Manitoba Steam and Pressure Plants Act

Boilers that develop less than 3 boiler horsepower (126,000 BTU input), those used for heating single family or duplex homes, and unfired pressure vessels under 10 cubic feet volume are exempt from inspection and certification requirements.

A Certificate of Authorization is required to install all boilers, pressure vessels and pressure piping systems regardless of size. The following application with all required documents must be submitted to Inspection and Technical Services.

Systems Exceeding 17 cubic feet

  • If the system exceeds 17 cubic feet in volume, determined by using Chart to Determine if Pressure Piping Installation Exceeds 17 cubic feet, you must also obtain a Canadian Registration Number for the system. You must submit installation design drawings and specifications for approval, along with your traveler, before beginning work. For information about registering piping designs, please consult the Design Registration Program of Pressure Equipment Programs.


The Steam and Pressure Plants Act and Regulation governs the design, fabrication, installation, operation, repair and inspection of pressure equipment in Manitoba. The legislation adopts various codes, standards and specifications as minimum requirements. The minimum requirements described in these codes, standards and specifications, are the rules that Inspection and Technical Services design engineers and field inspectors adhere to and enforce.

Requirements for pressure equipment Design Review are contained within the Canadian Standards Association standards:
(a) B51-Boiler, Pressure Vessel, and Pressure Piping Code;
(b) B52-Mechanical Refrigeration Code.

What Designs Must Be Registered?

The two CSA standards, B51 and B52, contain administrative requirements for registering drawings, specifications and Data Reports with the jurisdictional authority. Manitoba has fully adopted the design registration requirements described by these codes for the following processes:

  • Registration of design for Boiler and other pressure equipment
  • Registration of design for pressure piping of a volume 17 cubic feet and larger
  • Registration of pressure fittings
  • Registration of welding and brazing procedures
  • Welding and brazing qualifications
  • Submission of Manufacturer's Data Report
  • In-Service Repairs and Alterations
  • Fabrication Inspection (Including Imported Equipment)
  • Registration of refrigeration system designs

The Steam and Pressure Plants Act imposes additional requirements for registering:

  • propane storage tank locations and
  • ammonia storage tank locations.

How to Register Designs in Manitoba

Drawings, specifications and calculations relating to the design of each boiler, pressure vessel, fitting, fired-heater pressure coil, and pressure piping intended for use in Manitoba shall be submitted for registration to the Office of the Fire Commissioner

Once accepted and registered, a Canadian Registration Number for that design will be issued. Any number of pieces of equipment may be made from the registered design, and each shall carry the CRN with the appropriate suffix (.4) to show registration in Manitoba.

Registration Submissions must include:

  1. The company's valid Manitoba Certificate of Authorization licence number, or evidence of Quality Control certification from the ASME (American Society of Mechanical Engineers), or certification by another recognized pressure equipment quality audit certification agency.
  2. Completed application form for each design
  3. Two copies of drawings and calculations
  4. Evidence of registration by the original registering province (if applicable)
    Registration fee in cheque or money order, payable to the Manitoba Minister of Finance.

The following applications and forms are available to register designs in Manitoba:

General Requirements for Design and Fabrication of Pressure Piping Systems

All pressure piping systems for use in Manitoba shall be designed and constructed in accordance with the applicable ANSI/ASME Piping Codes and the Manitoba Labour and Immigration, Steam and Pressure Plants Act.
