| Abstract |
Cracks in concrete buildings are stopped by injection of sealants containing epoxy resins or polyurethanes as the main component. The hazards posed by this type of work are caused by the high-pressure pumps needed for application of the sealant and by the toxic substances contained in the sealant. The epoxy resins and hardeners are flammable and can cause skin and respiratory diseases. The polyurethanes contain toxic isocyanates and amines. Both groups of substances can cause skin diseases. Outlined protective measures include: the supply of overalls, safety gloves, safety spectacles and respirators, the avoidance of smoking and other ignition sources, periodic inspections of the equipment and efficient ventilation. |
