Chemical Waste Guidelines

It is the responsibility of the chemical storage facility to ensure that all chemical waste has been properly packaged, labeled, inventoried and to arrange pickup by the chemical waste company.

All chemical waste to be disposed of should be sent to the chemical storage facility. Chemical waste must be examined before being placed in the chemical storage facility and can not be simply left at the entrance.

It is the responsibility of people who generate chemical waste to ensure that all chemical waste is in a sealed container and properly labeled.

Partially filled containers will not be accepted. Much of the chemical waste is generated annually and thus should be bulked in large containers until full.
 

Labeling:

All chemical waste containers should contain a label stating that it is "Hazardous Waste", ingredients or contents and its general classification.

Hazardous waste can be classified as follows:

1) flammable

2) oxidizers

3) toxic

4) corrosive: acid or base

Organic wastes must be separated into either non-chlorinated or chlorinated organic waste and labelled accordingly. Small amounts of non-chlorinated waste can be placed in a chlorinated waste container but chlorinated waste can not be added to a non-chlorinated waste container.
 

Organic – Chlorinated and Non-chlorinated:

Organic wastes must be separated into either non-chlorinated or chlorinated organic waste and labelled accordingly. Small amounts of non-chlorinated waste can be placed in a chlorinated waste container but chlorinated waste can not be added to non-chlorinated waste.

Individuals wishing to waste small amounts(less than 1 L) of organic non-chlorinated and organic chlorinated waste are asked to contact me. Waste containers have been set up in the chemistry labs so that these waste chemicals can be bulked for waste disposal. This reduces costs associated with the storage and disposal of chemical waste. Large amounts of chlorinated and/or non-chlorinated chemical waste must be placed in a properly sealed container, labelled hazardous organic chlorinated or non-chlorinated waste. When full the CSF should be contacted to arrange a time for that chemical waste to be be properly inventoried and placed in the CSF.
