Study Notes
Red Seal Occupational Standards (RSOS)
- Red Seal Occupational Standards set the standard for a Red Seal trade
- They replaced National Occupational Analyses (NOA) in 2015
- They support consistency in learning resources, assessments, and increased industry involvement
- They focus on apprenticeship training and skills assessment with industry-defined learning objectives, outcomes, and performance criteria
- NOAs are still used for trades without RSOS developed
- There are clear benefits to understanding the RSOS for your trade
Red Seal Occupational Standard Requirements
- Each RSOS or NOA outlines trade requirements for a Red Seal trade
- They include:
- Trade activities (tasks and sub-tasks)
- Skills and knowledge requirements
- Summary of essential skills
- Safety information
- Trends affecting the trade
- Technical terms
- Names of tools and equipment
- Acronyms
RSOS Specific Requirements
- RSOS include:
- Learning objectives and outcomes
- Industry expected performance
- Red Seal examinations are based on the RSOS or NOA
- Provincial and territorial apprenticeship systems use Red Seal Standards to design training programs
Task 1 - Performs safety-related functions
- When a coworker is not wearing proper PPE, the most appropriate action is to approach them and remind them of the importance of PPE.
- Reporting the incident to the supervisor without speaking to the coworker is not the most effective solution and may not address the immediate safety concern.
Task 2 - Performs routine work practices
- Attending team meetings is typically a routine work practice.
- The first step in creating a new filing system for digital documents is to assess the current system and identify its strengths and weaknesses.
Task 3 - Organizes work
- When faced with more urgent tasks than time allows, prioritize the most critical tasks and communicate with stakeholders about the ones that cannot be completed.
Task 4 - Uses and maintains tools and equipment
- Regular maintenance on tools and equipment aims to extend their lifespan and ensure safe, efficient operation.
- When a piece of equipment is making an unusual noise but seems to be functioning normally, it should be immediately taken out of service and reported to maintenance.
Task 6 - Diagnoses engine and engine support systems
- A failing fuel pump is not typically associated with worn connecting rod bearings, loose or worn timing chains, or faulty hydraulic lifters.
- Intermittent stalling while driving, with the check engine light on but no codes stored in the ECU, could be caused by a faulty crankshaft position sensor, clogged fuel filter, worn spark plugs, or a combination of these factors.
- Excessive oil consumption without visible leaks can be caused by worn piston rings.
Task 7 - Repairs engine and engine support system
- When replacing a timing belt, it is crucial to align the timing marks on the crankshaft and camshaft(s) to ensure proper engine timing.
Task 8 - Diagnoses drive trains
- The differential allows different wheel speeds during turns.
- The clutch in a manual transmission system engages and disengages power from the engine to the transmission.
- The first step in diagnosing a vibration in the drive train is to perform a visual inspection of all drive train components.
- When diagnosing a problem with the differential, the most appropriate starting point is to perform a road test to listen for unusual noises.
- When diagnosing a slipping transmission, checking the transmission fluid level and condition is an important step.
- A clicking noise during sharp turns, more pronounced during sharp turns, typically indicates a worn CV joint.
- Difficulty shifting into certain gears with a functioning clutch could be caused by worn synchronizers in the transmission.
- In a four-wheel-drive vehicle where the front wheels are not receiving power, the transfer case should be investigated first.
Task 9 - Repairs drive trains
- Automatic transmissions typically use Automatic Transmission Fluid (ATF).
- When replacing a clutch, the clutch disc, pressure plate, and pilot bearing should always be replaced.
- A crucial step when replacing a drive shaft is to ensure it is balanced.
- When replacing differential gears, the backlash needs to be adjusted, and the gear pattern checked.
- When rebuilding a manual transmission, ensuring correct synchronizer end play is crucial for smooth gear changes.
- A clutch that does not disengage properly after replacement could be due to the clutch disc being installed backwards, pressure plate bolts not tightened to the correct torque, or improper adjustment of the clutch cable or hydraulic system.
- A new vibration increasing with speed after a drive train repair could be caused by an unbalanced drive shaft.
Task 10 - Diagnoses hydraulic, hydrostatic and pneumatic systems
- Hydraulic systems use liquids, while pneumatic systems use gases.
- A pump converts mechanical energy into fluid energy in a hydraulic system.
- The accumulator stores energy and dampens pressure fluctuations in a hydraulic system.
- In a pneumatic system, the Filter-Regulator-Lubricator (FRL) unit cleans, controls pressure, and adds oil to the air supply.
- Hydrostatic systems use an incompressible fluid to transmit power.
- When diagnosing a hydraulic system with slow cylinder movement, the condition of the seals in the cylinder should be checked first.
- Operating the system and observing for foaming or bubbles in the reservoir is an appropriate step when suspecting air in a hydraulic system.
- When diagnosing a pneumatic system with low pressure, leaking air lines and connections should be checked.
- In a hydrostatic transmission system, pressure testing and flow testing can help determine the condition of the pump and motor.
- Erratic movement in hydraulic actuators, after checking for air in the system and proper fluid levels, could be caused by a worn pump, contaminated hydraulic fluid, or a faulty pressure relief valve.
- Slow operating speed of pneumatic tools, despite a functioning compressor, may be caused by a clogged air filter in the FRL unit, leaking seals in the tools, or undersized air lines.
- In a hydrostatic drive system losing power under load, the cause could be a worn pump or motor, sticking check valves, or improperly adjusted compensator.
- Overheating in a hydraulic system, with correct fluid level and functioning cooler, could be caused by a partially clogged filter, improper valve timing, or internal leakage in components.
Task 11 - Repairs hydraulic, hydrostatic and pneumatic systems
