Noise exposure in the workplace: Changes coming soon in Québec

Workers who are exposed to high noise levels for long periods of time will suffer irreversible hearing damage (tinnitus, deafness). Although noise exposure limits exist, Québec’s Commission des normes, de l’équité, de la santé et de la sécurité du travail (CNESST) estimates that hearing disorders related to working conditions are constantly increasing, which represents 86% of occupational diseases in 2021,1 compared to 70% in 2019. It’s crucial for all employers to inform their employees of the harmful, long-term effects of noise, to focus on prevention and to implement the necessary mechanisms to comply with the noise standards set out in the Regulation respecting occupational health and safety. But what target values must we apply? When and how must we assess the noise levels workers are exposed to? And is there a tracking record of previous assessments?

Tonnage control under maximum and instantaneous power constraints

This paper presents a control solution to optimize ore transportation on a transfer conveyor belt fed by variable speed feeders. The purpose of this advanced regulatory control is to always operate at mechanical and electric constraints rather than at a sub-optimal average throughput.
