How to take care of safety during PUR foam application?
PUR foam spraying must be carried out by qualified workers who observe all safety measures. The greatest risk to health is observed when the components of which the polyurethane foamis made up are mixed. Harmfulness of components in liquid form results from high concentration of chemical substances, which may negatively affect health of workers during foam application. The toxicity of the PUR foam is then a threat, which the employee minimises by following strictly specified safety rules.
In order to maintain full occupational safety, during the foam application by the spraying method, the workers follow strict safety rules, which prevent poisoning, burns or damage to eyesight. Workers are equipped with goggles, work clothes, protective masks, gloves and ear plugs. The expert technician has adequate knowledge of how to operate and service thermal insulationequipment. They also know how to protect the surrounding space from being covered with foam.
PUR foam impact on the indoor air
The choice of thermal insulation material is not only limited to its insulation efficiency. Its lowest possible harmfulness to humans and animals, and its positive effect on the air inside the building are equally important. What effect does polyurethane have on the air? The harmfulness of this thermoinsulator is defined as zero - it is a completely safe insulation material for living organisms. It is worth noting that polyurethane is used in hundreds of forms every day, such as cushions, seats, shoes, coverings or even children's toys.
Toxicity of PUR foam is a myth - you do not have to be afraid of negative effects of the components from which it is made. Polyurethane foam is entirely harmless to health once it has dried. Tests carried out by PU Europe have not indicated the presence of harmful and toxic substances.
PUR foam and mould growth
Is polyurethane foam toxic? Not at all - it is 100% safe for household members and animals. It does not emit any odours or harmful substances. Its structure is physiologically inert. It does not react with steam or any chemicals. As part of the "battle" between PUR foam and moisture , polyurethane foam is the winner, in particular its closed-cell variant, e.g. Purios H.
Foam absorbability is only 2%, moreover - it does not lose its insulating properties in humid environment. This confirms the versatility of PUR foam as a thermal insulator. Decay of polyurethane covered wood is practically impossible. This property prevents formation of mould and fungi, creating an environment safe for health and life of household members. It is recommended especially for houses inhabited by people with reduced immunity, exposed to respiratory diseases.
