AVON GAS MASK SIZING MANUAL
See the user manual for component replacement intervals. If any deterioration or damage is suspected to any component, replace immediately. Once in use, components subject to ageing (especially valves) must be routinely replaced to maximise useful life. Only use a mask if a fit check is satisfactorily completed.Ī: The S10 mask has a 20 year shelf life based on the mask being correctly stored prior to use (instructions on storage are provided upon purchase). Also wearers are advised to conduct a quantitative fit test, at least annually, to confirm the correct face mask size has been selected. Wearers must always conduct a negative pressure fit check prior to use to make sure the mask will seal to the face. Also, as a rule of thumb, your eyes should be at, or just above, the centre line of the eye lenses. Avon can provide you with a sizing tool which helps to assign the right size of mask. Q: How do I make sure I have the right size of S10?Ī. The mask had two different types of canisters a metal one used for riot control and training and a heavier plastic type that can cope with NBC agents: These are supplied in silver vacuum packed units, a spare one being carried in the haversack: The back of this canister has a label indicating it was made in 2005: The following information about fitting comes from the manufacturer’s website:Ī: There are four sizes available with a six buckle fit allowing quick donning: One innovative feature of this mask was a tube that allowed the soldier to drink whilst wearing the mask: This is wrapped around the diaphragm when not in use and could be uncurled and attached to the waterbottle as required: A second speech diaphragm is provided on the opposite side to the canister: This mask was made by Avon in 2004, the details being moulded into the facepiece: The canister uses a standard 40mm thread, allowing any NATO respirator filter with a 40mm standard thread to be fitted to the mask: A set of rubber straps are fitted to secure the mask to the head, with adjustors allowing a ‘comfortable’ fit to be achieved: The lenses on the mask are flat and secure to the face of the mask with a plastic ring: These can be swapped out for prescription lenses or black/red tinted lenses as required. The front of the mask is dominated by a large exhale valve which combines a speech diaphragm: Note the red fibre disc secured to the front with a split ring, this would have the owners details written on. The S10 is similar to its predecessor in general form, having a side mounted canister, but is a far more sophisticated design and made of a harder rubber than the earlier model: The rubber is extremely durable and has a service life of twenty years.
