A hazard is defined as a chance; a chance of being injured or harmed by a possible source of danger. Jobsites are filled with many different hazards- whether it's the task you are performing, task others are performing around you, equipment, chemicals, heat sources, or weather conditions. Hazards should be recognized and eliminated through engineering controls, administrative controls, and as a last resort, personal protective equipment.
According to OSHA, caught-on or -between hazards collectively is one of the four deadliest dangers found on a construction site, and one of the biggest hazards for workers in industrial processing as far as unguarded machines and equipment. Workers' fingers, arms, hair, and other body parts as well as protective clothing can be caught or entangled in unguarded machine parts or equipment, which is known as a caught-in or -between hazard.
So, safety glasses, hard hats, safety footwear. What does this all mean and what is PPE or personal protective equipment? In today's world of new gadgets, tools and machinery, which tend to make life easier, there is always the ever increasing risk of injury. For example, 20 years ago if you opened your garage you probably had a weed whacker, leaf blower, chain saw and hedge trimmer. All separate tools, each for a specific job. In 2017, there is now one tool available for all 4 applications! Amazing, awesome and yet still as potentially dangerous as the tools of 20 years ago. This applies to the same thought that when exposed to any hazard, we should never rely on PPE alone. I mean let's face it, just because a hard hat is worn doesn't mean the hazard miraculously disappears, does it?
