J. Chemical Surplus Removal Request Form

Each container must bear an unique identification number. The unique container number consists of the 2 to 4-letter departmental code, the 6-digit date, and the sequential numerical numbering starting with the number "001".

Example of a container identification number:

CHEM-010391-001

All materials picked up from departments by OSU HAZMAT must be accompanied by a completed Chemical Surplus Removal Request Form. This form and Hazardous Chemical Surplus Tags are available from OSU HAZMAT. Photocopies of this form are acceptable if the form is still legible.

The instructions for completing the Chemical Surplus Removal Request Form are as follows (See Appendix K for example):

1. Request made by:
   Name of the person responsible for making the request for chemical removal.

2. Phone:
   Phone or extension number of person responsible for making the request for chemical removal.

3. Department:
   Name of department generating the hazardous substance(s).

4. Date of Request:
   Today's date. This date should correspond to the 6-digit date on the container ID labels.

5. Name:
   Name of departmental contact person responsible for coordination of hazardous substances waste and surplus pickup operations (DCHO).

6. Phone:
   The telephone number or extension at which the listed contact person may be reached.

7. Building and Room #:
   Building and room number where the DCHO can be found.

8. Is it necessary to call...?
   Self-explanatory.

9. Chemicals for pick-up are located:
   Where the chemicals are being stored for removal.

10. Department Head Signature:
    Signature of department head (or administrative equivalent) or their authorized representative who can attest that all items are properly classified, described, packaged, marked, and labeled, and are in proper condition for transportation according to the applicable requirements of the OSU Environmental Health Services Hazardous Materials Section as described in this document or other information provided to the generating department concerning hazardous chemicals and chemical waste disposal. Only one signature is needed per request/pick-up (not every page).

11. 6-Digit Date:
    Use the 6-digit date of the day you start listing chemicals on the Request. Example: July 15, 1990, would be 071590 (do not use hyphens). Continue to use the same 6-digit date as long as container numbering is consecutive or until the manifesting is completed. Do not change the 6-digit date because you are continuing to add chemicals to the list over a period of several days. When the 6-digit date is changed, container numbering starts over with "001".

12. Departmental Code:
    List the departmental code on each container. (See Appendix H for departmental code assignments).

13. Container Number:
    Each container must be assigned a consecutive number starting with the number "001". Any time the 6-digit date category is changed, container numbering starts with "001" again.

14. Description of Contents:
    Provide the following information on each container, using as many manifest lines as necessary:

    • Common name of the substance(s) or chemical abstract name.
    • Strength (concentration) of individual substance, where applicable.
    • Percentages of mixed chemicals in container (by volume).

    • Other information for transporting personnel, as deemed important by the generating department.

15. Physical State:
    List the physical state of the material at the time of the manifest utilizing one of the following codes listed on the form.

16. Volume of Material in Each Container:
    List the approximate volume of material in each container, not the original container volume.

17. Hazard Code(s):
    Check the appropriate hazard code for the material (See "Hazard Identification"). The Hazard codes are listed as on the form.

K. Hazard Identification

Each material shall be identified with a "Hazard Code" abbreviation to be used as a general description to provide information on handling hazards and responsive action in the event of an accident.

Each material shall be identified on the form by the hazard that most closely indicates the greatest hazard presented by the material. The following is a list of hazards and their definitions. The codes are listed on the form.:

• Flammable: Any compressed gas, liquid, or any solid material (other than an explosive, heat sensitive or shock sensitive material) that is liable to cause fires through friction, absorption of moisture, spontaneous chemical changes, retained heat from processing, or which can be ignited readily, and when ignited burns so vigorously and persistently as to create a serious transportation hazard.
  
  Examples: Acetone, methyl alcohol, dimethylamine, propane, sodium dithionite, nitrocellulose.
• Corrosive: Any gas, liquid, or solid that causes destruction of human tissue or a liquid that has a severe corrosion rate on steel or aluminum. Aqueous solutions that have a pH equal to or less than 2 or equal to or greater than 12.5 are corrosive. Other liquids are defined as corrosive if they corrode SAE 1020 steel at a rate greater than 6.35 mm/year at 55oC.
  
  Examples: Hydrochloric acid, sulfuric acid, acetic acid, sodium hydroxide.
• Oxidizer: A substance such as chlorate, permanganate, inorganic peroxide, nitrocarbonitrate, or a nitrate that yields oxygen readily to stimulate the combustion of organic matter. (Organic peroxides are to be listed under "OTHER", and the hazard listed on the bottom of the form.)
  
  Examples: Sodium nitrate, potassium permanganate, manganese dioxide.
• Toxic: Substances such as carcinogens, irritants, or poisonous gases, liquids, and solids which are irritating to or affect the health of humans.
  
  Examples: Phosgene, phenol, 1-naphthylamine, arsenic compounds, mercury.
• Water Reactive: Substances that react violently when in contact with water. They can be either be flammable solids or corrosives. (Mark the label with both Water Reactive and flammable or corrosive).
  
  Note: In many cases the water reactive material can be chemically treated, thereby removing the reaction characteristic. The material may still contain other hazardous constituents. Please contact OSU HAZMAT for further information and guidance.
  
  Examples: Lithium, potassium or sodium metal, antimony pentachloride, acetic anhydride, calcium carbide.
• Carcinogens: Any substance that causes the development of cancerous growths in living tissue, either those that are known to induce cancer in man or animals or experimental carcinogens that have been found to cause cancer in animals under experimental conditions.
  
  Examples: 1-Naphthylamine, benzidine, dimethyl sulfate.
• Teratogens/Mutagens: Teratogens are agents that cause growth abnormalities in embryos, genetic modifications in cells, etc. Mutagens are substances that are able to induce mutations in DNA and in living cells.
  
  Examples: Diethylstilbestrol (DES), diethyl sulfate.
• Other: Special hazards such shock or heat sensitive, organic peroxides, pyrophorics (reacts with air), peroxide formers.
  
  Examples: Picric acid, urea nitrate, 2,4-dinitrophenylhydrazine, benzoyl peroxide, phosphorus, isopropyl ether.
