ApprenticeshipApprenticeship is post-secondary education with a difference. Apprenticeship begins with finding an employer.Employers hire apprentices, pay their wages and provide on-the-job training and work experience. Approximately80 per cent of an apprentice’s time is spent on the job under the supervision of a certified journeyperson orqualified tradesperson. The other 20 per cent involves technical training provided at, or through, a postsecondary institution – usually a college or technical institute.To become certified journeypersons, apprentices must learn theory and skills, and they must pass examinations.Requirements for certification—including the content and delivery of technical training—are developed andupdated by the Alberta Apprenticeship and Industry Training Board on the recommendation of Refrigeration andAir Conditioning Mechanic Technician Provincial Apprenticeship Committee.The graduate of the Refrigeration and Air Conditioning Mechanic apprenticeship training is a journeyman who will:xxxxxxxxxxsupervise, train and coach apprenticesuse and maintain hand and power tools to the standards of competency and safety required in the tradehave a thorough knowledge of the principle components of refrigeration systems, heat/cool units and air conditioninghave a thorough knowledge of the electrical and automatic controls used in all aspects of the refrigeration and airconditioning industrybe capable of assembling, installing or over hauling all componentshave an intimate knowledge of other mechanical trades, which contribute to refrigeration and air conditioning systemsbe proficient in the use of test instrumentsexercise good judgment and resourcefulness in construction, maintenance and workplace health and safetyknow, and be able to apply their knowledge of the installation, and service of HVAC systems in accordance with local,provincial and national standards for the industrydo all Refrigeration and Air Conditioning Mechanic tasks expected of a journeyman.Apprenticeship and Industry Training SystemIndustry-DrivenAlberta’s apprenticeship and industry training system is an industry-driven system that ensures a highly skilled,internationally competitive workforce in more than 50 designated trades and occupations. This workforce supportsthe economic progress of Alberta and its competitive role in the global market. Industry (employers andemployees) establishes training and certification standards and provides direction to the system through anindustry committee network and the Alberta Apprenticeship and Industry Training Board. The Alberta governmentprovides the legislative framework and administrative support for the apprenticeship and industry training system.Alberta Apprenticeship and Industry Training BoardThe Alberta Apprenticeship and Industry Training Board provides a leadership role in developing Alberta’s highlyskilled and trained workforce. The board’s primary responsibility is to establish the standards and requirementsfor training and certification in programs under the Apprenticeship and Industry Training Act. The board alsoprovides advice to the Minister of Advanced Education and Technology on the needs of Alberta’s labour marketfor skilled and trained workers, and the designation of trades and occupations.The thirteen-member board consists of a chair, eight members representing trades and four membersrepresenting other industries. There are equal numbers of employer and employee representatives.Industry Committee NetworkAlberta’s apprenticeship and industry training system relies on a network of industry committees, including localand provincial apprenticeship committees in the designated trades, and occupational committees in thedesignated occupations. The network also includes other committees such as provisional committees that areestablished before the designation of a new trade or occupation comes into effect. All trade committees arecomposed of equal numbers of employer and employee representatives. The industry committee network is thefoundation of Alberta’s apprenticeship and industry training system.-2-
Local Apprenticeship Committees (LAC)Wherever there is activity in a trade, the board can set up a local apprenticeship committee. The board appointsequal numbers of employee and employer representatives for terms of up to three years. The committeeappoints a member as presiding officer. Local apprenticeship committees:x monitor apprenticeship programs and the progress of apprentices in their trade, at the local levelx make recommendations to their trade’s provincial apprenticeship committee (PAC) about apprenticeshipand certification in their tradex promote apprenticeship programs and training and the pursuit of careers in their tradex make recommendations to the board about the appointment of members to their trade’s PACx help settle certain kinds of disagreements between apprentices and their employersx carry out functions assigned by their trade’s PAC or the boardProvincial Apprenticeship Committees (PAC)The board establishes a provincial apprenticeship committee for each trade. It appoints an equal number ofemployer and employee representatives, and, on the PAC’s recommendation, a presiding officer - each for amaximum of two terms of up to three years. Most PACs have nine members but can have as many as twentyone. Provincial apprenticeship committees:x Make recommendations to the board about:xstandards and requirements for training and certification in their tradexcourses and examinations in their tradexapprenticeship and certificationxdesignation of trades and occupationsxregulations and orders under the Apprenticeship and Industry Training Actx monitor the activities of local apprenticeship committees in their tradex determine whether training of various kinds is equivalent to training provided in an apprenticeshipprogram in their tradex promote apprenticeship programs and training and the pursuit of careers in their tradex consult with other committees under the Apprenticeship and Industry Training Act about apprenticeshipprograms, training and certification and facilitate cooperation between different trades and occupationsx consult with organizations, associations and people who have an interest in their trade and withemployers and employees in their tradex may participate in resolving certain disagreements between employers and employeesx carry out functions assigned by the boardx.Refrigeration and Air Conditioning Mechanic PAC Members at the Time of PublicationMr. Art McMullen .

Technical Institutes and CollegesThe technical institutes and colleges are key participants in Alberta’s apprenticeship and industry training system.They work with the board, industry committees and Alberta Advanced Education and Technology to enhanceaccess and responsiveness to industry needs through the delivery of the technical training component ofapprenticeship programs. They develop lesson plans from the course outlines established by industry and providetechnical training to apprentices.Apprenticeship SafetySafe working procedures and conditions, incident/injury prevention, and the preservation of health are of primaryimportance in apprenticeship programs in Alberta. These responsibilities are shared and require the joint effortsof government, employers, employees, apprentices and the public. Therefore, it is imperative that all parties areaware of circumstances that may lead to injury or harm.Safe learning experiences and healthy environments can be created by controlling the variables and behavioursthat may contribute to or cause an incident or injury. By practicing a safe and healthy attitude, everyone canenjoy the benefit of an incident and injury free environment.Alberta Apprenticeship and Industry Training Board Safety PolicyThe Alberta Apprenticeship and Industry Training Board (board) fully supports safe learning and workingenvironments and emphasizes the importance of safety awareness and education throughout apprenticeshiptraining- in both on-the- job training and technical training. The board also recognizes that safety awareness andeducation begins on the first day of on-the-job training and thereby is the initial and ongoing responsibility of theemployer and the apprentice as required under workplace health and safety training. However the boardencourages that safe workplace behaviour is modeled not only during on-the-job training but also during allaspects of technical training, in particular, shop or lab instruction. Therefore the board recognizes that safetyawareness and training in apprenticeship technical training reinforces, but does not replace, employer safetytraining that is required under workplace health and safety legislation.The board has established a policy with respect to safety awareness and training:The board promotes and supports safe workplaces, which embody a culture of safety forall apprentices, employers and employees. Employer required safety training is theresponsibility of the employer and the apprentice, as required under legislation other thanthe Apprenticeship and Industry Training Act.The board’s complete document on its ‘Apprenticeship Safety Training Policy’ is available atwww.tradesecrets.gov.ab.ca; access the website and conduct a search for ‘safety training policy’.Implementation of the policy includes three common safety learning outcomes and objectives for all trade courseoutlines. These common learning outcomes ensure that each course outline utilizes common language consistentwith workplace health and safety terminology. Under the title of ‘Standard Workplace Safety’, this first section ofeach trade course outline enables the delivery of generic safety training; technical training providers will providetrade specific examples related to the content delivery of course outline safety training.-4-
AddendumAs immediate implementation of the board’s safety policy includes common safety learning outcomes andobjectives for all course outlines, this trade’s PAC will be inserting these safety outcomes into the main body oftheir course outline at a later date. In the meantime the addendum below immediately places the safety outcomesand their objectives into this course outline thereby enabling technical training providers to deliver the content ofthese safety outcomes.STANDARD WORKPLACE SAFETYA.Safety Legislation, Regulations & Industry Policy in the Trades .Outcome:B.1.Demonstrate the ability to apply the Occupational Health and Safety Act, Regulation and Code.2.Explain the role of the employer and employee in regard to Occupational Health and Safety(OH&S) regulations, Worksite Hazardous Materials Information Systems (WHMIS), fireregulations, Workers Compensation Board regulations, and related advisory bodies and agencies.3.Explain industry practices for hazard assessment and control procedures.4.Describe the responsibilities of workers and employers to apply emergency procedures.5.Describe positive tradesperson attitudes with respect to housekeeping, personal protectiveequipment and emergency procedures.6.Describe the roles and responsibilities of employers and employees with respect to the selectionand use of personal protective equipment (PPE).7.Select, use and maintain appropriate PPE for worksite applications.Climbing, Lifting, Rigging and Hoisting .Outcome:C.Describe legislation, regulations and practices intended to ensure a safe work place in thistrade.Describe the use of personal protective equipment (PPE) and safe practices for climbing,lifting, rigging and hoisting in this trade.1.Select, use and maintain specialized PPE for climbing, lifting and load moving equipment.2.Describe manual lifting procedures using correct body mechanics.3.Describe rigging hardware and the safety factor associated with each item.4.Select the correct equipment for rigging typical loads.5.Describe hoisting and load moving procedures.Hazardous Materials & Fire Protection .Outcome:Describe the safety practices for hazardous materials and fire protection in this trade.1.Describe the roles, responsibilities features and practices related to the workplace hazardousmaterials information system (WHMIS) program.2.Describe the three key elements of WHMIS.3.Describe handling, storing and transporting procedures when dealing with hazardous material.4.Describe safe venting procedures when working with hazardous materials.5.Describe fire hazards, classes, procedures and equipment related to fire protection.-5-
Workplace Health and SafetyA tradesperson is often exposed to more hazards than any other person in the work force and therefore should befamiliar with and apply the Occupational Health and Safety Act, Regulations and Code when dealing withpersonal safety and the special safety rules that apply to all daily tasks.Workplace Health and Safety (Alberta Employment, Immigration and Industry) conducts periodic inspections ofworkplaces to ensure that safety regulations for industry are being observed.Additional information is available at www.worksafely.orgTechnical TrainingApprenticeship technical training is delivered by the technical institutes and many colleges in the public postsecondary system throughout Alberta.
