Final answer:
Appropriate clothing for the lab includes cowboy boots with closed toes & no holes and rubber "duck" boots for foot protection, and a long-sleeved jacket under a lab coat for arm protection. Sandals, neckties, and dangling jewelry are unsafe for lab environments.
Step-by-step explanation:
In a science lab, it is important to wear clothing that ensures safety. The appropriate clothing items from your list are cowboy boots with closed toes & no holes and rubber "duck" boots because they provide adequate protection for your feet in case of spills or dropped materials. Additionally, a long-sleeved jacket worn under your lab coat can protect your arms from potential hazards.
Sandals or flip-flops, neckties, and dangling jewelry are not considered safe because they expose your feet to spills, can get caught in equipment, or come into contact with chemicals, which creates safety risks. It's also beneficial to tie back long hair and avoid loose clothing that could catch on equipment or flames. Safety gear that you would normally not wear outside of a science lab includes lab coats, safety glasses or goggles, and gloves when handling hazardous materials.
