Many of employees wearing some accessories and don’t think twice about it.  However, there are risks to your safety when working.  The following are tips to help protect you on the job so fashion does not mix with danger.

1. When operating equipment that have rollers or that are designed to feed objects, be aware of ties and long necklaces.  These items can easily get caught and pull you toward the machine resulting in everything from bruising to strangulation.

2. If working in field operations or around equipment, be aware of any rings you wear and consider taking them off prior to work.  Rings can easily get caught and fingers and/or hands can be bruised, cut, scared or worse, severed.

3. Be sure to wear properly fitted pants.  If worn low for trendy purposes, it is possible to trip and fall causing injuries to many parts of your body.

4. When wearing high heels, be sure to watch your step.  Cracks in pavement, frays in area rugs, holes in carpet and uneven surfaces can be great traps for pointed shoes and could cause you to trip and fall.

‘Personal Clothing and Accessories’ mandates that “dangling neckwear, bracelets, wristwatches, rings or similar articles must not be worn. 

A simple reminder: Jewelry really doesn’t have a place in the workplace. Dressing appropriately for your job could save you from a fatal injury or even save your life!

Anyone wearing a ring is at risk for a ring avulsion injury, especially if you wear a ring while operating industrial machinery.

Ring can create several safety hazards for those working around chemicals. A spilled or splashed caustic chemical can get under a ring or watchband, burning or irritating the skin.

In short, no. Your hands come in contact with plenty of surfaces and substances every day, which can potentially harm your engagement ring. While it's safe to keep it on for most activities, take it off when you know you'll be working heavily with your hands or if you could potentially expose it to harsh chemicals.

The damage can also cause blood clots and bone fractures in your damaged finger. Ring avulsions can damage any part of your finger including your: Skin and surrounding soft tissue (like muscles and fat).
