Medical Laboratory Professionals' Association of Ontario (MLPAO) Practice Exam

The correct choice, which indicates that the risk is not associated with the WHMIS symbol, focuses on the symbol's specific implications. WHMIS, or the Workplace Hazardous Materials Information System, uses distinct symbols to quickly communicate the hazards of various substances. Each symbol corresponds to certain risks based on the properties of the materials they represent.

The option stating "May cause environmental damage from fumes" does not align with the typical hazards indicated by most WHMIS symbols. While it's crucial to consider environmental impacts in a broader context, the primary symbols under WHMIS usually center on immediate health and safety risks in the workplace, such as flammability, toxicity, or reactivity, rather than environmental issues stemming from fumes.

In contrast, the other options all reflect common risks associated with hazardous materials. The possibility of a substance reacting with water, being chemically unstable, or unexpectedly burning are all critical concerns directly related to the properties and behavior of specific substances as indicated by their corresponding WHMIS symbols. This highlights the importance of understanding not just the symbols, but also their specific indications regarding risks to ensure a safe working environment.
