LEARNING THE LANGUAGE OF SAFETY: SIGNS,

SYMBOLS, AND LABELS

(2)

 Hazard recognition, an essential skill

needed by every laboratory worker, is

presented through the basics of

understanding labels, signs, symbols,

terms, and other sources of information.

A hazard is a possible source of danger, and our world holds many hazards.

The point is that many things, including chemicals, that we use everyday have not only very substantial benefits but very real hazards.

The positive side of these hazardous materials is that we can learn how to maximize the benefits while at the same time minimizing the hazards of these things by taking certain steps.

When working in the laboratory, as in any other workplace, you will encounter chemicals or other materials or processes that just like the rest of the world have both benefits and hazards. Your safety and the safety of others depend on your developing the skill to recognize hazards and to manage, control,or minimize the risks of those hazards.

This section introduces some basics of recognizing hazards in the laboratory—the language of hazards.

A laboratory is usually a very safe place to work.

However, if you work in a laboratory, you are

likely to encounter chemical, biologic,

radiation, or physical hazards. This section

focuses on recognizing chemical hazards,

while other sections deal with other kinds of

hazards.

Look at the Label!

You should always examine the label to look

for hazard information, and this information

often comes in specific terms or symbols

denoting the hazard or hazards of a

chemical.
