Stop, drop, and roll

Emergency procedure to extinguish flames on a person by stopping, dropping to the ground, and rolling.

Glass tubing insertion into stopper

Inserting glass tubing into a stopper using matched hole size and lubrication to ease fit.

Stopper hole

The hole in a stopper into which glass tubing is inserted.

Lubrication for insertion

Twist insertion

Insert glass tubing by twisting; never push to avoid breakage.

Hand protection during insertion

Use towels or protection to guard hands when handling glass tubing.

Check labels and instructions

Verify that the correct chemicals and equipment are used and according to procedures.

Hazardous chemicals awareness

Know which chemicals are hazardous and understand safety implications.

MSDS (Material Safety Data Sheet)

A document with hazard information and handling instructions for chemicals.

Do not return reagents / exchange stoppers

Never pour reagents back into bottles, exchange stoppers, or leave stoppers on the table.

Acid dilution rule

When diluting acids, always pour acid into water, not the reverse.

Hands away from face

Keep hands away from face, eyes, and clothes while handling solutions or materials.

Acid/alkali burn treatment
