Introductions

3. Agenda Dust Adequacy How RPE works
Protection factors and what they mean
Mask types
Suitability
Task & environment
Wearer
Fit testing
Agenda

4. Sources of Dust Found in the Workplace Settled dust
Brought into the Workplace
Powder for paints, flour for bakeries
Created by the work processes
Sawn wood, abrasion and polishing
Agenda

5. Substances Particulates Gases & Vapours Dusts Mists Fibres Fumes
Germs & bacteria
Gases & Vapours
Gases
Vapours
What are we protecting from, Particles, Gases and Vapours.
What is a particulate – ask for examples.
A dust may be silica dust off cutting
A mist may be a spray
Fibres great example for construction is asbestos
Fumes a good example is a burn from a weld
Germs and bacteria can be HIV, Hepatitis
Gases and vapours are not protected from the same type of filter. Gases and vapour filters are made up of impregnated carbon. This is not to be discussed today, however we can discuss questions later.

6. Health effects from dust exposure
Skin disorders
Obstruction in the nose
Nasal cancer
Stomach disorders
Sore eyes
Respiratory disorders
Asthma
Silicosis

7. How Does Dust Enter the Body?
Inhalation
Ingestion
Absorption (Through mucous membrane of the eyes)

8. Particle Sizes Inhalable dust Enters the nose (under 100 microns)
Thoracic dust
Enters trachea (under 10 microns)
Respirable dust
Enters the alveoli (under 7 microns)
Most harmful

9. Talk through the respiratory system, run through the difference of inhalable and respirable dusts
Inhalable dust being those that we breath in as we inhale, the hairs in the nose act as a barrier for these dusts, as do saliva, coughing and sneezing.
Respirable dusts capable of penetration deep in to the alveoli. .
Explain how RPE works, dusts are trapped by electrostatic filter materials, namely a filter stopping the respirable dusts reaching the deep lung.
***Tear up a mask and show the filter 3M 9000 series demonstrates this well. Use the balloon demonstration.

10. Dust Control Measures Elimination Substitution Enclosure LEV
General Ventilation
Reduced Exposure Time
P.P.E./ R.P.E.
Monitoring / Health Surveillance

11. Protection Factors & Markings
CE marking APF – assigned protection factor EN149:2001 P WELs
P1 – APF 4 NPF 4
P2 – APF 10 NPF 12
Run through what the letters codes mean on a respirator
CE – marking, the knowing that the product has passed for European standard
APF is the assigned protection factor
EN149:2001 – European standards the mask has to meet
P – Particulate factor being 1,2 or 3
We then need to explain what P and APF mean ????? How do we do this easily
P3 – APF 20 NPF 50

12. Types of respiratory
Talk through rpe being the last line of defence, eliminate, reduce, isolate, control, ppe
Run through the masks types
Disposable
Half mask
Full face masks
Powered
Demo on how to fit
Talk through the suitability
How long is the mask to be worn
What is the wearer doing
What other PPE has to be worn
Does the wearer have facial hair
Any pre-existing medical conditions
Does the wearer need to wear spectacles
Ensure the options of what is best to wear are discussed

13. Face fit testing Qualitative Taste test
P1, P2, P3, disposable and re-usable half mask
Quantative
Probe test
P2, P3, disposable, re-usable half mask and full face mask
Note Powered respirators do not require face fit testing
Discuss face fit testing
Discuss the 2 types qualitative and quantative, talk through the lack of protection if the mask does not fit correctly.
Discuss when the face fit testing is to be repeated.

14. Masks in use and maintenance
Training
Pre-use checks
Check fit
Management & supervision
Maintenance
Follow manufacturers instructions
Competent person
Records
Appropriate times (28 days)
Storage
Masks in use
Ensure training has been carried out, fitting and donning is understood, ensure pre-checks are understood what to look for and how to replace, carry out a face seal test before use to ensure the mask is comfortable and fitting correctly.
Supervisors and managers to manage and supervise, look out for tell tail signs of the masks not fitting, straps being crossed, glasses fogging up.
Maintenance
Ensure competent persons are trainged in record keeping and the checking of masks, if individuals are carrying out checks all must be trained, discuss record keeping and why, talk through the 28 day rule anything over 28 days classed as re-usable, anything under 28 days disposable show a 3M 4000 series.
Talk through the storage of masks, not on top of head worse place it can go as hair is electrically charged.
