Concrete does not burn – it cannot be set on fire and it does not emit any toxic fumes when affected by fire. Concrete is proven to have a high degree of fire resistance and, in the majority of applications, can be described as virtually fireproof. This excellent performance is due, in the main, to concrete''s constituent materials (cement and aggregates) which, when chemically combined ...

The actual application of the fireproofing is not a high silica producer. Mainly due to the "wet" product as it''s applied. It''s messy but keeping it wet keeps the silica from becoming airborne. However, someone has to mix the dry product and make the slurry. This individual has an exhaust ventilation above (see picture). He/she opens the bag into the mixing hopper, adds water and then ...
