Infographic: Nanomaterials


Nanotechnology refers to a wide range of technologies and materials that create, manipulate, or use particles that are extremely small and have dimensions roughly between 1 and 100 nanometres (nm). A nanometre is 1 billionth of a metre. Most research and studies have concentrated on nanomaterials with at least one dimension of less than 100 nm.

Nanotechnology is a field that is quickly changing both in terms of how we use it, and in our understanding of it. The best approach to take is the precautionary principle - the need to take prudent action in the face of potentially serious risk, without waiting for the completion of further scientific research.

Share this infographic with examples of how nanomaterials are used in the workplace and in the home, the potential health effects from exposure, and what employers can do to protect workers.

Mental Health Tips for Employers Fast Fact Card

10 Healthy Habits

There is no one-size-fits-all formula to create a mentally healthy workplace because every workplace is different - from the people doing the work, to the work that needs to be done, to the size of the organization, to the available resources at hand. However, commitment from leadership is essential for any organization to be successful.

Share this card which outlines 10 ways in which employers can support positive mental health, from encouraging employee participation in decision making to developing policies that take into account all mental and physical risk factors. By creating a culture of positive mental health, workplaces can become productive, safe and healthy spaces that foster worker growth, development and well-being.

These information cards are printed double-sided, with English on one side and French on the other, on sturdy card stock with a UV coating for added durability. Note that a minimum order of 10 cards is required.

We also offer a fast facts card with healthy habit tips for workers and a handout on steps to a mentally healthy workplace.
