Fibre Optic safety wrt wavelength

Afternoon,

We have lots of fibre links on our local sites using 850nm and 1300/1310nm and they've always been deemed as 'safe', i.e. won't be blinded/damaged if accidentally shone in an eye. Is this assumption correct? Would this be the same if we jumped up to using longer wavelengths e.g. 1550nm. Common sense and basic training says don't stare down fibres anyway but are there special requirements needed when using longer wavelength/long distance SFPs? e.g. PPE, locking cabinets/fibre trays, signage etc.

When googling for this, I get info about the hazards of splicing, which isn't what I'm after.

Regards,

Kris.
