Had some watered down ratio 1 to 2 hypo in a 1 litre spray thing which leaked into a flexitub in bank of van. Knew something was leaking when driving along, now chest hurts a bit not massively. washed out tub and know the correct mask filter to use when putting it on patio. The swimming pool shop i bought it from said all their metal shelf brackets had rusted because of the chlorine tablets in the shop and maybe the hypo in the shop as well. Want to store, transport and use this stuff safely, anyone know anything?
