PPE (Personal Protective Equipment) is not a modern concept. Human beings have been making equipment to protect themselves for hundreds of millennia. There are numerous examples from across history – many related to warfare. Even in this field there are examples of provision for a more diverse group, including women. Perhaps one of the most famous example is the suit of armour provided by Charles VII of France for Joan of Arc. And yet, the provision of PPE that genuinely takes into account the needs of a truly diverse workforce remains poor. Diversity in PPE is about much more than just making smaller versions of protective equipment for women.
