Claims2
A method of fireproofing and insulating a tank car, comprising:
- providing a multi-layer fireproof insulation roll, comprising:
- a first layer having a first length, the first length substantially equal to a circumference of the tank car, the first layer being fire retardant,
- a second layer positioned on the first layer and bonded thereto, the second layer having a second length, the second length being equal to the first length of the first layer, the second layer being thermally insulating, and
- a first strap positioned between the first layer and the second layer, the first strap having a third length greater than the first length and the second length;
- positioning the multi-layer fireproof insulation roll on a top surface of the tank car;
- unrolling the multi-layer fireproof insulation roll, thereby wrapping the multi-layer fireproof insulation roll around the circumference of the tank car;
- and
- securing the multi-layer fireproof insulation roll by pulling the first strap towards a bottom of the tank car.
