During renovation, it’s not unusual to remove stone or concrete. For example, in the case of water leakage, a concrete floor in the basement may have to be partially removed to repair pipes. Or kitchen counters made of quartz or granite may be removed by sledgehammer. These are examples of instances where a property owner can unknowingly be exposed to silica. Particles of silica that become airborne during work activities can severely affect the health of the occupants. As a property owner, you should be aware of the dangers of silica and how avoid health hazards.
