Description

SAFETY SYMBOLS In order to recognize the dangers some chemicals may have, scientists have developed two systems to help identify chemicals that may harm us.

HHPS (

Symbols)

This is a set of symbols that warn consumers (people who buy products) what dangers a product may contain. These symbols are simpler than the WHMIS symbols (see next page) because they are directed at the general public who may not have any scientific knowledge.

Symbol

Meaning

Description A substance that can cause immediate damage or harm to any living organism. A substance that can catch f

very easily.

Example:

.

A substance that can explode very easily if h

or d

Example:

.

.

A substance that can easily burn through other pieces of matter. Example:

.

The HHPS system not only uses these four symbols, but it also describes to us how severe the danger is. The shapes around the symbols and the colour of the symbol are used to communicate the severity.

WHMIS (

Materials

System)

WHMIS (pronounced wim-is) is another system developed by scientists that is mandatory in any employment setting, from f & chemical plants to h and s . It is a program that all employees must be made aware of. If you currently have a part-time job, you most likely will be taking a seminar in WHMIS. Similar to HHPS, WHMIS also uses safety symbols to let users know what dangers the chemical may possess.

Meaning

Description A gas is under very high p

container and therefore may explode easily. Example:

Same meaning as in HHPS.

Contains highly reactive o

(more dangerous

than the oxygen we breathe). Example:

Same meaning as in HHPS.

Can combine with almost any chemical around it and cause a potentially dangerous reaction (especially with w
