EVALUATION grid OF The SUSPENDED CEILINGS

The decree of January 15, 1998 defines the evaluation method of asbestos containing suspended ceilings.
The evaluation varies from 1 to 3:
- 1: periodic control of the state of conservation of the product,
- 2: monitoring of the level of dust contamination,
- 3: removal.

The result is obtained by filling from left right the columns of the following grid:
