It will suffice to compare the potential impacts OBJECTIVES: 3-(Bromomethyl)-2-chloro-4-(methylsulfonyl)-benzoic acid (BCMBA) has not previously been identified as a respiratory sensitiser. We detected two cases who presented respiratory and urticaria symptoms related to BCMBA and had positive skin prick tests to the agent. In Canada, the Controlled Products Regulations (CPR) define a pure substance or tested mixture as a respiratory tract sensitizer—if there is evidence that shows that it causes respiratory tract sensitization in persons following exposure to it in the work place. Sensitizers are chemical substances that can cause sensitization in the lungs (respiratory sensitizers) or to the skin (skin sensitizers) after exposure. Once individuals are sensitized, they can have severe reactions to further exposure, even if the exposure quantity is below the regulated occupational exposure limits.

A chemical is classified as a skin sensitizer if there is evidence in humans that the substance can lead to sensitization by skin contact in a substantial number of persons, or if there are positive results from an appropriate animal test.

irritant, though some substances, such as chrome salts, can act as both irritants and sensitisers. Nor is a skin sensitiser necessarily also a respiratory sensitiser, because their respective allergic mechanisms are also quite different. However, a few substances, such as rosin, are capable of this double allergenic role.
