Potosí: Overview

Travel Warning: Mine Tour Warning

Travelers planning a trip to the cooperative silver mines in Potosí should first be aware of the risks involved. These are working mines and conditions are harsh. At an altitude of over 4200m (13780ft) temperatures can range from below freezing outside to over 45°C (113°F) deep in the mines. Visitors may be exposed to a range of harmful substances including silica dust (the cause of silicosis), arsenic gas, acetylene vapors, asbestos fibers, the byproducts of acetylene combustion and explosives residues. Medical experts, including the NHS, note that limited exposure to these conditions is extremely unlikely to cause any lasting health damage. However, if you have any concerns about exposure to these potential risks, you should reconsider taking the tour. Anyone with medical conditions such as claustrophobia, asthma or other respiratory conditions should not enter the mines. Serious accidents can also occur and all tour operators should make you sign a disclaimer waiving any liability for death, injury or illness; if they don't, choose another. Visiting the mines is a serious decision. If you're undeterred, you'll have an eye-opening and unforgettable experience.
