The integrated materials handling prevention strategy combines training and intervention and is based on the understanding, observation and analysis of five principles of action. These principles are common to all handling techniques used by workers. 

This video illustrates Principle 1: Reducing the initial load.

Opportunities for the worker to reduce the intensity of the initial load by performing manoeuvres before lifting (pre-manoeuvre). The purpose of these manoeuvres is to reduce the distance between the load and the worker's body and to limit the bending of the worker's trunk, which have an influence on the amount of initial load.

Cette vidéo illustre le Principe 1: Réduction du chargement initial.

Possibilités qu’a le travailleur de réduire l’intensité du chargement initial en effectuant des manoeuvres avant de la soulever (prémanoeuvre). Ces manoeuvres ont pour but de diminuer la distance entre la charge et son corps, ainsi que de limiter la flexion de son tronc, qui ont une influence sur la quantité de chargement initial.
