Answer:

Loose clothing or long hair can be dragged through chemicals in beakers or open flames (such as on a Bunsen burner) or get caught in equipment. Long, loose sleeves on a shirt or sweater can even knock over items on the bench top.

When working in a lab, PPE is almost always necessary to protect workers from chemical exposures and other hazards. A lab coat or other protective clothing should be worn whenever chemicals or biological materials are handled. The lab coat will protect the wearer’s personal clothing and exposed skin (such as on arms) from contaminants. Lab coats should be buttoned closed for best protection. Gloves should also be worn whenever handling hazardous materials, even in small quantities. It is important to choose the appropriate type glove for the hazard present, such as chemical resistant gloves, heat resistant gloves, etc. Be aware that no chemical resistant glove protects against all chemical hazards. Read the Material Safety Data Sheet for guidance on the appropriate type of glove to wear, or consult with lab supply distributors for glove vs. chemical comparison charts when choosing chemically resistant gloves.
