[Occupational risks surveillance in informal vendors from Maputo: Experience of the use of direct observation for its monitoring].

Over 90% of employment in Mozambique is informal. Given scarce resources and difficulties with monitoring informal employment, little is known about exposure to occupational hazards among informal workers in this country. Direct observation is a simple, easy, economical and rapid method for monitoring and obtaining data. We describe our experience with the use of direct observation of occupational hazards among informal street vendors in Maputo. Results reveal a high percentage of vendors are exposed to occupational hazards without any form of protection. Direct observation is a good method for monitoring occupational risks in exploratory phases of research or as a complementary method to quantitative data collection.
