An Occupational Disease Cluster Investigation
Dryden Weyerhaeuser Recovery
Boiler #4 (RB4)
The Dryden Weyerhaeuser Recovery Boiler #4 project seeks to further investigate the RB4 exposures and related health issues.
If you have information to contribute to this project, see our questionnaire below.
• Mercury • Hydrogen sulfide • Methyl mercaptan • Carbon monoxide
among multiple other chemical exposures
The following issues have been reported by workers and are being investigated by OHCOW:
• Neurological* • Stomach • Intestinal • Heart Conditions
* especially memory issues
OHCOW was brought in to determine if there was a correlation between the job and the symptoms most workers were experiencing.
In late 2004, OHCOW held an intake clinic to gather information regarding health issues experienced by workers.
OHCOW is now in the process of outreach to follow up with workers regarding the outcomes of their claims and their current health status.
As the cluster investigation is still ongoing, OHCOW is seeking input from workers who worked at the Air Emissions Recovery Boiler #4 Project at Weyerhaeuser Pulp and Paper Mill in Dryden, Ontario between 2002 – 2004.
If you, or one of your family members*, has been affected by this situation, we would appreciate you taking the time to complete our questionnaire.
This questionnaire is the first step in our investigation and is an important mechanism to not only help us, but to sign up for updates.
*For deceased workers, the questionnaire can be completed by their next-of-kin.
