According to a new report from the Massachusetts Toxic Use Reduction Institute (TURI), entitled “Asthma-Related Chemicals in Massachusetts,” more than 300 substances are known or suspected to cause or exacerbate asthma, and that “[m]uch of the evidence (for identifying these substances) comes from workers exposed in the workplace.”
Asthma is an increasingly common chronic lung disease that kills more than 500 Canadians annually. The most common symptoms include shortness of breath, chest pain or tightness, coughing and wheezing.
Based on the report’s findings, workers in a range of occupations may be exposed to ammonia, chlorine, formaldehyde, diesel exhaust or any of the other 300-plus chemicals identified in this report as causing asthma symptoms. Lab workers, woodworkers, construction workers, plumbers, farmers, painters, and those in industries that produce metals, plastics, electronics, rubber and textiles are just a few examples of workers who are at risk. Asthma-causing substances are also commonly found in most cleaning products, including those found in most workplaces and homes.
The Canadian Lung Association reports that three million Canadians are suffering from asthma, and 25% of them have symptoms that are triggered or made worse by exposure in the work environment. That means hundreds of thousands of workers are affected. In addition, they report that up to 15% of new asthma cases are caused by workplace exposures.
There needs to be greater effort on the part of workplaces to either eliminate these substances or minimize worker exposure to them. The TURI report identifies more than 300 different chemicals, and that information should be used to develop strategies for replacing substances with those less harmful, and to isolate those that can’t be replaced, in order to reduce exposure.
In Ontario, occupational health and safety law requires that employers take steps to protect workers from harmful substances, and it gives workers the right to know about hazardous substances through the Workplace Hazardous Materials Information System (WHMIS). The province’s new Toxics Reduction Act (TRA) may also prove useful in safeguarding workers and the public from harmful substances including those linked with asthma.
The Ontario Ministry of Environment (MOE) is currently working to develop regulations that effectively implement of the Toxics Reduction Act, and those regulations should be completed this fall. In the meantime, it would be a good idea for supervisors to read . Slated for completion in the fall of 2009, the content and enforcement of these regulations will help determine how effective the legislation will be.
For our part, the Workers Health & Safety Centre has developed information resources and training programs to help workers, joint committee members and others better understand how to identify and eliminate exposure to harmful chemicals including asthma-causing substances.
Supervisors should read the Massachusetts report, as well as the Toxics Reduction Act, and the WHSC asthma fact sheet, in order to prepare for the new regulations coming down the pike. TURI also a database of potential cleaning solution alternatives that could be helpful.
Asthma is an increasingly common disease, and workplaces will have to prepare to stem the tide very soon. It’d be best to prepare now for the changes that are coming.
