  • Face potentially hazardous job conditions (e.g., fly ash, asbestos, arsenic) that require a specific response. Boilermakers assess the situation to determine what action should be taken and then implement the solution (e.g., choose appropriate safety equipment, isolate the area, call insulators to strip asbestos). (2)
  • Work in situations where many tradespeople are required to complete a job at a worksite that can only safely accommodate a limited number of tradespeople at any given time. They sequence tasks within their own team to complete the work on schedule. They also coordinate with other trades (e.g., electricians), considering such factors as safety and the optimal use of person hours across trades. (3)

Job Task Planning and Organizing

Own Job Planning and Organizing

Boilermakers' job task planning and organizing responsibilities are dependent on their work setting (shop or construction). In some cases, boilermakers may be given a project to complete and a technical drawing to follow. They decide upon the production sequence and task allocations in conjunction with their supervisor. Time management is determined by the project timelines.

In other cases, boilermakers are given detailed instructions by their foreperson, which often include the daily production schedule and assigned tasks (although the former can be determined jointly at the pre-job planning meeting). The day-to-day organizational requirements of the job are very dependent upon the projects involved. In some situations, identical parts are being produced or identical tasks being performed, making each day repetitive and easy to plan. In other situations, different tasks are being performed or a variety of products being made or repaired which presents a number of planning challenges, including frequent interruptions. Sequencing, scheduling and coordinating are very important when several trades are involved in a project. Effective planning is especially important if the worksite cannot safely support several individuals working at the same time. (3)

Planning and Organizing for Others

Any boilermaker can be called upon to serve as a working foreperson if there are six or less boilermakers in a crew. A working foreperson has additional planning responsibilities such as organizing the tasks of the crew as well as other tradespeople involved in the job. A working foreperson determines daily production schedules, sequences tasks, coordinates work schedules across trades, and ensures timelines are met. When working forepersons plan and organize others, they consider the number of workers the site can safely accommodate at any one time, optimal use of person hours for all trades involved, job deadlines, task sequencing, the skill mix of crew members, and numbers of workers assigned to the crew. Planning and organizing others is not a primary responsibility of the occupation, but the position of working foreperson is important when assumed. (3)

Significant Use of Memory
  • Remember priorities and directives for the day (item, short term, several pieces of information).
  • Remember where they were in a task when they left off in terms of completing a task if they are called away to a higher priority situation. Often several hours can elapse before their return, resulting in a need to recall exactly what they were doing when they left (serial order, short term, several pieces of information).
  • Memorize parameters such as tolerances, and procedures such as the steps involved in acquiring permits (serial, short term, several pieces of information).
Finding Information
  • Obtain information on safe work practices from co-workers and supervisors during safety toolbox meetings. (1)
  • Locate information in a technical handbook regularly to review procedures, mathematical equations, specifications, symbols and equipment. (1)
  • Contact their supervisor to obtain information about procedures or technical problems. (1)
  • May refer to a catalogue to get a part number or the name of a piece of equipment. (1)
  • Consult peers to gain technical knowledge and assistance with problems. (1)
  • May refer to a collective agreement to verify pay rates and worker rights. (1)
  • Consult with quality control officers, engineers and/or draftspersons to get information about blueprints and design. (1)
Digital technology
  • May use digitized programmable equipment such as scientific calculators, digital levels and lasers. (1)
  • May use application equipment (robotics) and computer-controlled equipment such as welding overlays. (1)
  • May use computer-assisted training tools such as on-line programs or software packages for health and safety training. (1)
  • May use computer-assisted design (CAD) software to modify drawings. (2)

Working with Others

Boilermakers work with others at Complexity Level 4. Boilermakers are not allowed to work alone due to the potentially dangerous nature of their work; therefore, working with others is a critical skill. Often a welder is paired with a mechanic to form a skills team. Boilermakers may also work in larger team situations and with other tradespeople. They should be able to communicate effectively, complete the tasks assigned to them and integrate their work with that of the other trades. They must be self-disciplined, ensuring that work done independently is accurate and completed within prescribed time limits. It is advantageous if boilermakers demonstrate leadership abilities by helping the team to organize its work schedule and coordinate assignments. Boilermakers in an industrial/commercial setting must be able to get along with their co-workers because they will work closely with these individuals for years. Boilermakers are expected to respect their supervisors and to assist those workers with less experience and expertise. There are two types of forepersons in this occupation. The working foreperson (if there are six or less boilermakers) supervises the crew for the duration of the job and is also part of the working group. When there are more than six boilermakers, there is a designated foreperson. This person is in a defined position of authority and assumes more of a supervisory role, assigning tasks and responsibilities.

Continuous Learning

Technical upgrading is offered by companies when new products, procedures and equipment are introduced. The Trades Training Trust Fund provides comprehensive technical and theoretical training as well as refresher courses such as blueprint reading and basic trade math. The Fund also provides first aid and safety training (e.g., Workplace Hazardous Materials Information System, H2S Alive, confined space). Boilermakers may take courses at community colleges (supervisory skills, computer skills, first aid) or access on-line programs. One of the most practical ways for boilermakers to gain new expertise is to learn on the job from more experienced co-workers or supervisors. It is common for boilermakers to also have welding certification. These skills are pursued through apprenticeship training.
