What Are the Working Conditions?

Insulation workers generally work indoors. They spend most of the workday on their feet, either standing, bending or kneeling. Sometimes, they will be required to work in confined spaces; such as: tunnels, lifts, ladders and other high places. The work is not strenuous and requires more coordination than strength. Insulation work is often dusty and dirty. The minute particles from insulation materials, especially when blown, can irritate the eyes, skin and respiratory system. Removing cancer-causing asbestos insulation is a hazardous task and is done by specially trained workers. To protect themselves from the dangers of asbestos and irritants, workers follow strict safety guidelines, take decontamination showers, keep work areas well ventilated and wear protective suits, masks and respirators. Insulation workers must be able to climb and able to work at heights. Insulation workers must be able to travel. Some of these locations will be 80 or more miles from home. These workers will be expected to provide own transportation to get to these sites.
