EFFECTIVE December 15, 2016


The National Joint Rules and Standards Committee has amended Article 5, Registration, of the Uniform Referral Standards and Joint Referral Rules, effective December 15, 2016. These amendments apply to the Domicile requirements.


These amendments may be viewed by going to the login page of the MBDS and clicking on the link provided. You may also obtain a copy of the amendments by calling the hall.

Congratulations to Local Lodge #11 for being the 2015 recipient of the Charles W. Jones Award. What a great honor! The link below is the press release which is displayed on the MOST website and has been distributed to local (East Helena/Colstrip) media and to the construction trades media.


After being released from a job in our jurisdiction, call the hall to be released from the BDS. 

You must contact the hall that you were dispatched from when you are laid off to get back on the out-of-work list.

You are responsible for your own Common Arc Certification and updates! When working, let your steward know to update your Common Arc while still on the job.

You must contact the hall within two (2) business days of actual start of work if you obtain employment with an NTD employer.

Annual Drug Testing

The MOST Board of Trustees have amended the Drug Policy to include annual testing. The new policy will take effect on August 31, 2015. Anyone eligible for referral on the MBDS who does not comply with the new policy by the date will move to the ineligible list until a negative drug screen has been completed and received by the MOST office.

Please note that from this date forward any applicant that wishes to update their MOST drug screen can contact the MOST office directly for their chain of custody. MOST is also sending renewal cards to anyone who hasn't tested from February 1, 2013 to present so they know they need to test.

Contact MOST at 1-800-395-1089 if you have any questions or concerns.


Did you work at a Department of Energy site?

If so, you may be eligible for a FREE MEDICAL EXAM.
The Building Trades National Medical Screening Program (BTMed) provides a free medical screening for former construction/subcontractor workers who worked on a Department of Energy (DOE/AEC) site. This program is coordinated by CPWR - The Center for Construction Research and Training and is supported by the Building and Construction Trades Department, AFL-CIO with support from state and local BCTC.

Anyone who works in the boiler construction or repair trade.


A member of the International Brotherhood of Boilermakers, Iron Ship Builders, Blacksmiths, Forgers and Helpers.



Boilermakers and boilermaker mechanics make, install, and repair boilers, vats, and other large vessels that hold liquids and gases.  Boilers supply steam to drive huge turbines in electric power plants and to provide heat and power inbuildings, factories, and ships.  Tanks and vats are used to process and store chemicals, oil, beer, and hundreds of other products. Boilermaker mechanics maintain and repair boilers and similar vessels.  They inspect tubes, fittings, valves, controls, and auxiliary machinery and clean or supervise the cleaning of boilers using scrapers, wire brushes, and cleaning solvents.  They repair or replace defective parts, using hand and power tools, gas torches, and welding equipment, and may operate metalworking machinery to repair or make parts.  They also dismantle leaky boilers, patch weak spots with metal stock, replace defective sections, and strengthen joints.  Boilermakers regularly maintain and update components, such as burners and boiler tubes, to increase efficiency.



Boilermakers often use potentially dangerous equipment, such as acetylenetorches and power grinders, handle heavy parts, and work on ladders or on top of large vessels. The work is physically demanding and may be done in cramped quarters inside boilers, vats, or tanks that are often damp and poorly ventilated.  In some instances, work may be done at high elevations for an extended period.  To reduce the chance of injuries, boilermakers may wear hardhats, harnesses, protective clothing, safety glasses, shoes, and respirators.  Boilermakers may experience extended periods of overtime when equipment is shut down for maintenance.  Overtime work may also be necessary to meet construction or production deadlines.  At other times there may be periods of unemployment between jobs.



Apprenticeship programs usually consist of 4 years of on-the-job-training, supplemented by a minimum of 144 hours of classroom instruction each year in subjects such as set-up and assembly rigging, welding of all types, blueprint reading, and layout.  Those with welding training or a welding certification will have priority in applying for apprenticeship programs.  Experienced boilermakers often attend apprenticeship classes or seminars to learn about new equipment, procedures, and technology.  When an apprenticeship becomes available, the local union publicizes the opportunity by notifying local vocational schools andhigh school vocational programs.
