On dangerous or risky job sites, and within certain environments, personal protective equipment (PPE) must be worn at all times. It makes perfect sense, because the gear is designed specifically to mitigate severe or fatal accidents. Helmets, for example, protect the head from falling objects, overhead fixtures, and much more.
Some other notable PPE items include eyewear, steel-toed or reinforced boots, gloves, face shields, respiratory equipment, and high-visibility vests. While some of these may not necessarily expire, all protective gear must remain in top-notch and safe working condition.
