I will present the most common hazards, as they are perceived by workers (traditionally zoonoses, bites and scratches, allergies). Then I will present real data on accidents in research facilities including our facility. This will show that generally we are not focused on risks that are medically or numerically important. Finally I will talk about ‘emergent risks' (psychological and emotional risks) and will present the results of a Spanish study and the proposal for a ‘Spanish-speakers' global survey focused on these risks.
