SAFTEY OF STUDENTS

The Biochemistry laboratory can be a place of discovery and learning.

It can be a place of danger if proper common-sense precautions aren't taken

  Notify the teacher immediately of any unsafe conditions you observe.

PROPER HANDLING OF CHEMICALS AND EQUIPMENT

 Labels and equipment instructions must be read carefully before use. 

Set up and use the equipment as directed by your teacher.

PROPER HANDLING OF CHEMICALS AND EQUIPMENT

Many common reagents, for example, alcohols and acetone, are highly flammable. 

Do not use them anywhere near open flames.

PROPER HANDLING OF CHEMICALS AND EQUIPMENT

Always pour acids into water. If you pour water into acid, the heat of reaction will cause the water to explode into steam, sometimes violently, and the acid will splatter.

PROPER HANDLING OF CHEMICALS AND EQUIPMENT

Never point a test tube or any vessel that you are heating at yourself or your neighbor--it may erupt like a geyser.

PROPER HANDLING OF CHEMICALS AND EQUIPMENT

Beware of hot glass--it looks exactly like cold glass.

LABORATORY HYGIENE

Never eat, drink or smoke in a laboratory

Never apply cosmetics

Never touch your face, mouth or eyes
