Q:Do you know how you can avoid these hazards?


A:Wearing protective gear is one way to avoid many hazards in science. For example, to avoid being burned by hot
objects, use hot mitts to protect your hands. To avoid eye hazards, such as harsh liquids splashed into the eyes, wear
safety goggles. You can learn more about these and other lab hazards and how to avoid them at this URL: http://w

Safety Rules


Following basic safety rules is another important way to stay safe in science. Safe practices help prevent accidents.
Several lab safety rules are listed below. Different rules may apply when you work in the field. But in all cases, you
should always follow your teacher’s instructions.


Lab Safety Rules



  • Wear long sleeves and shoes that completely cover your feet.

  • If your hair is long, tie it back or cover it with a hair net.

  • Protect your eyes, skin, and clothing by wearing safety goggles, an apron, and gloves.

  • Use hot mitts to handle hot objects.

  • Never work in the lab alone.

  • Never engage in horseplay in the lab.

  • Never eat or drink in the lab.

  • Never do experiments without your teacher’s approval.

  • Always add acid to water, never the other way around, and add the acid slowly to avoid splashing.

  • Take care to avoid knocking over Bunsen burners, and keep them away from flammable materials such as
    paper.
