Fibre is the building material for cement plants, and is often treated as though it’s a hazardous material.
That’s because the plant must be heated to a temperature of more than 1,000C before the cement can be poured.
But that heat can increase the chance of the concrete cracking or leaking, leading to fires and other damage.
In a statement, the company said it is working to reduce the risk to its employees and contractors.
However, it also said that it is monitoring the impact on the environment and ensuring it can respond quickly to the risks.
The Irish company said that if there is an increase in the amount of concrete used, the risk of fire and damage will increase.
The company added that the amount that has been poured has been carefully monitored.
However in some instances, the amount has been too low to be considered a risk, according to the company.
