HSE Working Well Together Dust – Respiratory Protective Equipment Use as an opening slide

Sean Churchill Jennifer Turnbull Introductions

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

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

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.

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

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

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

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.

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

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

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

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.

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.
