The goal of maintaining adequate workplace hygiene is to protect the health and physical integrity of workers, thus preventing any harmful effects on health and occupational diseases that may result from exposure to chemical substances. To meet this goal, we must identify and evaluate risks as well as put into practice appropriate risk control methods.
The initial visit aims to identify any and all factors that could influence the variability of any future sampling so as to ensure representative conditions. The hygienist will observe the workstations to confirm, supplement or deny the theoretical conditions.
Sampling Strategy Development
The sampling strategy aims to assemble a sample of measurements representing the variability of the concentrations and is defined according to the objectives and constraints of the study.
Observations will be recorded on tasks, work organization, processes, environmental mapping, safety measures and procedures, emission sources, ventilation and other means of pollution control at the source as well as exposure times.
Statistical tools are used to compare each measured substance to the regulatory values (Regulation Respecting Occupational Health and Safety in Quebec, OSHA, NIOSH, ACGIH).
Compliance or non-compliance with the regulations is then determined followed by an action plan including implementation of corrective measures, additional preliminary assessments, and periodic checks.
