Coronavirus protection for site workers. Any example or source for an effective JSA?
(OP)
Hi All,
Trust you are all well and safe. I manage a small team of site workers (mainly welding supervision and inspection, but I suspect that in this sub-forum there is the largest number of site workers).
With the current virus outbreak (Australia), I need to plan a JSA for the workers that go on site.
Their activities will be mainly welding supervision / inspection.
Do you have any idea / link / file that you can and want to share?
Thank you in advance.

HEPA is really only meaningful in the context of high densities of dry, solid particles, since they can "bounce" off walls and structure, but "wet" particles have a high probability of sticking to surfaces they contact. CoV is carried by some amount of spittle or mucus, and cough aerosols tend average 8 um. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC46155...
According to https://scholarcommons.usf.edu/cgi/viewcontent.cgi... even an unsealed surgical mask is at least 50% efficient for 1 um particles; the author didn't test anything higher than 2 um, but one can presume that the masks are better than nothing for 8 um average size particles, particularly if we consider that the particles are also wet.

The size of the Coronavirus itself is most likely moot, since it cannot leave the body in that form, but is actually carried from the body by droplets in an aerosol, generated by coughing or sneezing. These droplets average 8 um

This HEPA manufacturer says they help but it's not a silver bullet

This one says yes, but I'm a bit leery. However, the article agrees with the coronavirus size given by dik
