all Laboratories.2. A set of simple Laboratory Rules to

be glued into student workbooks or booklet handouts

3

Safety Signs in Schools

All Laboratory doors should have warning signs to students.

All Preparation Rooms should have warning signs to students.

All Chemical Storage areas should be clearly labeled.

Refrigerators should be labeled if containing chemicals

4

Safety Training

Every school should have in place a Safety Training program for STAFF

and STUDENTS.This should occur as part of the first

week of the academic year for new staff and all students.

Inventories of all Equipment and Chemicals

All schools should have a hard copy of the Material Safety Data Sheets (

MSDS1), (MSDS2), (MSDS3) for every chemical held in the school.

These copies should be in one folder.

7

Chemical Disposal

You may have chemicals which are:

1. Out of Date2. Unlabelled (unknown)

3. Dangerous

8

Chemical Disposal

These chemicals will need to be disposed of in one of the following ways:

1. Down the sink with excess water2. Treated in some way first, then wash

to waste or other treatment3. Collected by a company and disposed

of safely (all J chemicals and unlabelled chemicals)

9

Chemical DisposalWhat you need to do.

1. Prepare a list of all chemicals which need to be disposed of including quantities.

2. Dispose of those chemicals that you can, using the “Aspects of Science Management

” pp. 50 – 613. Prepare a list of chemicals which need to be

disposed of by an outside agency. All J chemicals and unlabelled chemicals.

10

Chemical DisposalWhat you need to do.

Include on your list of chemicals to be disposed, any of the following that you have in your school:•Benzene•Carbon Tetrachloride•Potassium chlorate (potentially explosive with MnO2)•Mercury•Mercuric salts (eg. mercuric oxide, HgO)

11

Chemical DisposalFor the list of chemicals that need to be disposed of, by an outside agency (all J

chemicals that you are not going to keep):

1. Complete the table by downloading from http://csoscience.wordpress.com

2. Email this table to Greg Neave at g.neave@sec.gov.qa

3. Your school will need to contact a company to dispose of all chemicals.

Practice Examples

Explain what you would do now, if you find the following chemicals in your school

which are out of date:1. Ammonium metavanadate2. Acetamide3. Aluminium oxide4. Ammonium carbonate5. Ammonium dichromate

13

Practice Examples

1. Ammonium metavanadateDisposal Method J

Store safely for collection and disposal by an outside

agency

14

Practice Examples

2. AcetamideDisposal Method D

Wash to waste with running water.

15

Practice Examples

3. Aluminium oxide

Disposal method K

Dispose in normal waste bins.

16

Practice Examples

4. Ammonium carbonateDisposal Method C

Add a little at a time to a large quantity of water to dissolve. Wash

to waste with running water.

17

Practice Examples

5. Ammonium dichromateDisposal Method J

Store safely for collection and disposal by an outside agency.This is a powerful oxidizing substance

and should be stored away from all other chemicals especially organic substances.

18

In Summary:1. Complete a chemical and equipment

Inventory for your school (+MSDS’s).2. Prepare a list of chemicals which are:

• Out of Date• Unlabelled (unknown)• Dangerous (J chemicals)

3. Dispose of as many of these as you can safely.4. Email the final list to be disposed to Greg by
