2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

1. WHAT DO I NEED TO CONSIDER WHEN WEARING A RESPIRATORY PROTECTION
DEVICE FOR LONG PERIODS?
If you want to use the respiratory protection device at work for more than 30 minutes
every day then you first have to undergo the preventive medical examination required
under Convention 26 * (BGI 504-26) “Respiratory protection devices”. You also
have to comply with fixed recovery times.

2. HOW DO I USE AN SCBA?
Self-contained breathing apparatus (SCBA) are freely portable respiration devices.
They are worn either on the back or the hip with an appropriate harness.
Specific requirements for SCBAS as a safety device
in accordance with EN 137:
– Pressure gauge that can be read easily by the wearer (manometer)
– Warning device that gives an alarm at a residual pressure of 55 ± 5 bar
EN 137-1: applies to industrial applications
EN 137-2: contains additional requirements for fire fighting

How long can I use an SCBA at a stretch?
The duration of usage for breathing apparatus is between 10 minutes (short-term
SCBA) up to about 45 minutes (long-term SCBA). Depending on requirements, you
can use cylinder volume, pressure and thus the amount of compressed air specific
to your application. In addition, duration of usage depends on your personal air
consumption.
FOR EXAMPLE:
Compressed gas cylinder: Volume: 3 l
Pressure: 200 bar
Volume of air: approximately 600 l
Average air consumption: approximately 40 l/min
Usage time: approximately 15 min

3. HOW DO I USE A COMPRESSED AIRLINE SYSTEM?
A Compressed air hose unit is a type of non-freely portable breathing apparatus.
This means that by using a Compressed air delivery hose you can supply necessary
breathing air from the outside – either from an external air line or via breathing air
cylinders provided.
The requirements for compressed air hose units are governed by EN 14593.
There are three different types of compressed air hose units:
– With control valve
These devices provide a continuous stream of air.
➞ High air consumption
Use: with stationary air supply
– With normal-pressure regulator
The breathing air is used only for the inhalation cycle.
➞ Low air consumption
Use: for air supply from Compressed air cylinders
– With pressure regulator
The units generate an excess pressure of maximum 5 mbar in the respirator
(e.g. in the full-face mask). This is to prevent hazardous substances in the
ambient air from entering the mask.
Use: e.g. in atmospheres containing substances that exhibit acute toxicity

4. WHICH RESPIRATORY PROTECTION DEVICE FOR WHICH WORK?
Your choice of either a freely or non-freely portable breathing device depends on the
conditions of use and intended application. Self-contained breathing apparatus and
compressed air hose units are both open-circuit devices. They both offer the same
protection against airborne contaminants and oxygen deficiency.
The type of equipment you prefer to rely on at work depends on the conditions of use
and the intended application.
Self-contained breathing apparatus
Advantage: You can move around freely at work.
Disadvantage: Your breathing air supply is limited.
➞ Use, for example, in tight spaces or for temporary work, with respiratory
protection
Compressed air hose unit
Advantage: You have an unlimited supply of breathing air.
Disadvantage: You are severely limited in your range of motion.
➞ Long-term use, such as extended maintenance and cleaning work, or if the
chemical protective suit needs to be ventilated

5. WHAT TYPE OF CYLINDERS ARE THERE?
Compressed air cylinders are available with a filling pressure of 200 to 300 bar.
The pressure tank is made of steel, aluminium or carbon fibre composites (CFRP).
CFRP cylinders are the lightest and therefore offer the highest wearing comfort. The
pressure tank is fitted with a shut-off valve. The SCBA’s regulator is connected to
this valve.

IMPORTANT INSTRUCTIONS
In order to prevent the ingress of moisture and contaminants into the cylinder, you
should never lower the pressure below 2 bar. Compressed air cylinders must be
regularly maintained.
What information does the compressed air cylinder code give me?
What are the dangers of the cylinder? What does it contain? This information is given
to you in the clearly visible cylinder code, in accordance with EN 1089-3. A cylinder
with a black-and-white colour on its collar is a compressed air cylinder. The colour
coding only applies to the collar of the cylinder. You are free to choose the colour of
the shell, although yellow has become the norm in industry and fire fighting.
A label on the compressed air cylinder provides the following information:
– Composition of the gas mixture
– Risk and safety phrases
– UN number and gas name
– Name, address and telephone number of the gas manufacturer

6. THIS AIR IS PURE
If the concentration of hazardous substances at your workplace is too high and/or the
oxygen too low to protect your employees with filtering respiratory protection, then
you need to use self-contained respiratory protection.
External air can be provided in two different ways:
– from a compressed air supply: directly via a compressor or compressed air
network (pressure range 7 to 10 bar)
– from compressed air cylinders (nominal filling pressure maximum 300 bar)
How will the breathing air be extracted for self-contained respiratory
protection?
Using compressors (mobile or stationary), external air is compressed for the direct
compressed air supply or to fill the compressed air cylinder. Separators and filters in
the compressor ensure that the air is cleaned.

7. HOW CAN I GUARANTEE THE QUALITY OF EXTERNAL BREATHING AIR?
Whether it’s exhaust gases and water in the external air or lubricants from the
compressor, when creating breathing air you can never remove all impurities
completely. For the quality of the breathing air to comply with the requirements of
EN 12021, you must check it every six months in accordance with BGR 190. This
does not just depend on the accuracy of the methods, as the detection limits of the
methods must also be within the permitted values required.
How can I ensure that external breathing air is pure?
Compliance with limit values for carbon monoxide, carbon dioxide and water:
With Dräger’s proven tubes, you have a simple test system on hand – both for low
and high-pressure areas. This means you can check, quickly and comfortably on-site,
compliance with the limit values.
Compliance with lubricant limit values:
You can use the Dräger Impactor to check compliance with lubricant limit values. You
can also measure synthetic oils regardless of type and viscosity.
Limit values for impurities in external breathing air in accordance
with EN 12021:
– Lubricants (droplets or mist): 0.5 mg/m3
– Carbon dioxide content: (500 ppm)
– Carbon monoxide content: 15 ppm
– Water content*:
50 mg/m3
(at a nominal pressure of 40 to 200 bar) or
35 mg/m3
(at a nominal pressure of more than 200 bar)
(European reference condition: 1 bar absolute, 20 °C – published 2010)
* The current draft of EN 12021 (published July 2010) specifies various water content limit values for the low-
pressure range from 5 to 30 bar.

Dräger Aerotest 5000
The mobile Dräger Aerotest 5000 allows you to check the
purity of the breathing air supplied in a low-pressure system
(or, with accessories, in a high-pressure system), e.g. of
a compressor or compressed air cylinder. The reading is a
quantitative measurement of impurities in the stream of
compressed air. All components are immediately within reach
in a carrying case.
Dräger Air Guard
The Dräger Air Guard enables continuous, fully automatic
monitoring of the purity of compressed air for medical
applications. Dräger’s proven sensors also measure trace
gases. An automatic alarm sounds if pre-set limits are
exceeded – even in the event of short-term impurities. Alarms
can also be forwarded as potential-free contacts and used to
shut down e.g. the air compressor.
