Surgical masks are only any use against the surgeons dribbling or sneezing snot into wounds...
dont take offence as the respiratory protective equipment market is rather unregulated and many traders play on peoples naivety and people been uneducated in whats what as regards to RPE and PPE in general and buying cheap as its "only a small job" without understanding what does what.. Same goes for safety eye wear and gloves
Remember hearing of a builder working on a old petrol stating clearing the petrolum sludge from underground tanks with a shovel and bucket with a basic paper mask as shown below and having to be rescued when overcome by fumes...
I don't even bother buying a dust mask for basic DIY unless its approved to EN standards certified to P3 (highest filtration quality for particulate matter for negative pressure masks be it a dust mask a rubber half or full face respirator
even decent paper masks only offer protection if they fit right it wont be the first time ive seen people take masks off to see the black streaks of where muck has leaked in round the nose seal.. In the work place you should be face fit tested before commencement of work.....
(and clean shaved)
(i know this as i have been done in the past)
and if dealing with say Asbestos that leak can be lethal in the long run
Walk into any DIY store and you will find several "useless" masks

I wouldnt fancy rubbing old paint down with those masks above let alone rely on them offering any form of protection against any Pathogens be it a common cold to avian flu. to toxic dust such as asbestos or lead dust from old paint....
