Report:
- Rising of municipal castings = one of the most painful tasks of the cleaning operative, according to INRS research.
Cause:
- Excessive mass of the covers.
- Clogging of the covers → addition of effort (+ 50% minimum).
- Diversity of the types of manhole covers and the handling tools.
- Lack in training on the effective "postures".
Consequences:
- Onset or aggravation of lumbago.
- Intense cardiac solicitations.
- The prevention of these physiological disorders is conditioned by: - The opening convenience of the covers - The presence "help for the handling" - A "ergonomic" posture - Weights of castings "acceptable"
