A hand damaged by a burst hydraulic hoseFluid under pressure is a potential danger to both people and property. Serious injury or death can result from the failure of hydraulic pipes and hoses. The main dangers arise from components which are:

  • Worn or damaged
  • Incorrectly assembled or installed
  • Even as an apprentice fitter, you are considered a competent person. If any body is injured, or any property damaged as a result of your work, you are liable.
  • Do not attempt to select or assemble pipes, hoses and fittings unless trained to do so.
  • Always work to manufacturer’s specifications and recommendations.
  • Never use a mixture of products produced by different manufacturers.
  • Report all defects and never allow a potentially dangerous vehicle to be used.
  • Support any load and depressurise the system.
  • In the event of an accident or injury, or a risk that hydraulic fluid may have pierced the skin, seek medical help immediately. Report and record all serious incidents.

Precautions to take before dismantling a system:

Support any load and depressurise the system, then:

  • Mark everything before dismantling and tag all connections.
  • Blank hoses and ports to prevent contamination.
  • Contain spillage using oil dry or drain trays and clean area after completion of work.
  • Never expose yourself to the danger of a hydraulic rupture.
  • Work behind a guard, if necessary.
  • Avoid handling hydraulic fluids. Use suitable gloves.
  • Be careful when pressure testing hoses.
  • Do not smoke around, or expose hydraulic fluids to any naked flame.

During induction in Phase 2, you will be issued, free of charge, a pair of safety glasses.

Safety glassesThe purpose of the glasses is to protect your eyes during training. These glasses would normally be worn during activities such as battery testing, battery charging, drilling or grinding.

These glasses are an item of Personal Protective Equipment (PPE), and you get a free issue of this equipment.

Other items of PPE such as safety boots and overalls are your own responsibility.

It is entirely your own responsibility to present yourself each day for training, fully equipped and dressed.

Failure to do this can result in you being sent away to procure the necessary equipment.

The CP satellite unit in BaldoyleWhen the decision was made to close the Cabra Training Centre, the CP Fitters' Course, because of its size, presented a problem. None of the training centres around Dublin had sufficient space available to accomodate CP.

In order to get the course back up and running as quickly as possible, the decision was made to run two courses concurrently in a satellite unit in a Baldoyle industrial estate (view in Google Maps). 

It was decided that while the necessary extensive modifications were carried out in the FAS Training Centre in Baldoyle, the satellite unit would be used to run two courses concurrently from May to September, 2011. 

The satellite unit has been modified for CP with the addition of fume extraction for engine exhaust, hydraulic hose cutting, diesel injector testing and battery charging gasses. In addition, some extra electrical outlets and a local area network for our computers have been added. We have also added a wireless network to the workshops. You can check out some pictures of the move from Cabra to Baldoyle here.

The first two courses began on Monday, May 16th, and finished up on 30th September, 2011 (CP Fitters, May to September, 2011). Two further courses were run from January to May, 2012 (CP Fitters, January to May, 2012). As of August 2012, we are currently running another two courses in the satellite unit (CP Fitters, July to November, 2012). Once again, these courses are running concurrently. They began on July 9th and will finish up in 20 weeks later on November 23rd, 2012.

It now seems unlikely that the necessary building work to accomodate us in the Baldoyle Training Centre will be carried out. Areas of that centre that were to have been given to CP have now been allotted to other courses.

In addition, the breakup of FAS is imminent, so, for the moment, we have no further information on what will happen CP Fitters when these two courses finish. When we get this information, we will post it on these pages.

In the context of electricity and electronics, we come across this term in two contexts:

Magnetism:

Take the example of the rotor in an alternator. When we pass an electrical current through the rotor, we set up a magnetic field around the rotor.

We then move this magnetic field (spin the rotor) in close proximity to an electrical conductor (the stator) and we are now generating electricity.

The more electricity we pass through the rotor, the stronger the magnetic field becomes....up to a point.

More electricity means a more dense magnetic field (higher flux density). However, we will reach a point where we cannot make the magnetic field any stronger - the magnetic field is said to be saturated.

This explains why we do not need a current regulator in an alternator - we can only make the magnetic field so dense, and no denser, therefore we cannot produce 'too much' electricity. We only need to worry about a rise in voltage. The faster we spin the rotor, the higher the voltage rises, hence the need for a voltage regulator in an alternator.

Electronics

Transistors, as we know, can be used as switches and for amplification. As a transistor is used in a circuit, it operates in different states:

  • cutoff: When no current flows between the emitter and the collector in a bipolar transistor under no-signal conditions (nothing on the base), the transistor is said to be operating in a state of cutoff.
  • saturation: This is when a transistor is conducting as much as it can, given the difference in potential between the collector and the emitter.
    Initially, when we energise the base of a transistor with a low voltage and a small amount of current, we get a certain flow of electricity between the collector and the emitter.
    As we increase base current, we get a proportionally higher collector-emitter current (gain).
    We will reach a point where we continue to increase base current, and this will not produce more collector-emitter current, because of the fixed difference in potential between the collector and the emitter - the transistor is conducting as much electricity as it can, given the voltage difference between the collector and the emitter.
    At this point, the transistor is said to be saturated.

Standards Based Apprenticeship. Apprenticeship in Ireland is now standards based, as opposed to the old system of time served. This means that the apprentice must reach a pre-determined standard at each of the phases, before they can progress to the next phase.

VAG scannerElectronic tool used to access stored error codes. The tool can also be used to delete the stored error codes once repairs have been carried out. Shown here is one example.

CalculatorA calculator capable of carrying out the basic calculations involved in the maths and science related topics in Phase 2.

You are allowed to use a calculator in practical and theory examinations, but it is your own responsibility to have it with you on the day.

At the start of the course, you are issued with a basic calculator (at your own expense).
