1. Purpose:
The purpose of this SOP (Standard Operating Procedure) is to ensure proper and safe disposal of raw materials by setting guidelines and procedures for the staff handling these materials. This SOP will also minimize the environmental impact of the disposal activity.
2. Scope:
This SOP covers the disposal of all types of raw materials, including but not limited to unused chemicals, expired reagents, contaminated solutions, and broken glassware.
3. Responsibilities:
It is the responsibility of the person handling the raw material to dispose of it properly following the procedures outlined below.
4. Procedure:
4.1. Identification of the Raw Material:
Before disposal, all raw materials should be identified and categorized according to their chemical and physical properties. This information will assist in determining the appropriate method for disposing of the raw material.
4.2. Labeling of Raw Material:
All raw materials must be properly labeled with the contents, date received, and expiration date if applicable. This label should be present throughout the lifespan of the material and will ensure accurate and appropriate disposal.
4.3. Segregation of Raw Material:
Raw materials should be segregated as per their nature i.e., physical, chemical, and biological to determine their appropriate disposal method.
4.4. Segregation of Broken Glassware:
Broken glassware should never be disposed of in regular waste containers as it can injure the staff and cause environmental pollution. Broken glassware should be collected in a sturdy and labeled container for further recycling or disposal.
4.5. Packaging of Raw Materials:
It is recommended to store all raw materials in the original container. If this is not feasible, secure and labelled packaging should be used. Furthermore, if necessary, secondary packaging should be used to reduce the risk of any spillage or contamination during transportation.
4.6. Transport of Raw Materials:
During transportation, raw materials should be kept in sealed containers and must not be mixed. The vehicle used during transportation should be labelled according to the materials transported to minimize the risk of spillage or accidents. Additionally, it is discouraged to transport raw materials outside of regular business hours and with precautions in situations such as extreme heat, fire hazard areas, and contaminated areas.
5. Disposal of Raw Materials:
The following methods should be followed to dispose of raw materials:
5.1. Hazardous Waste Disposal:
Hazardous waste should be disposed of in agreement with local or federal regulations. The staff handling this category of waste should be thoroughly trained in handling and disposing of this material.
5.2. Chemical Disposal:
Chemical disposal should follow all applicable rules and regulations on chemical waste disposal and should be carried out in agreement with your local authority. It is recommended that chemical disposal is outsourced to a professional and licensed hazardous waste provider.
5.3. Broken Glass Disposal:
Broken glassware should be placed in puncture-proof containers wrapped in reinforced packaging, marked, and then disposed of according to local regulations.
5.4. Recycling:
If raw materials are recyclable, it is advised to do so through a professional and qualified recycling company to avoid negative environmental impact.
6. Documentation:
All material disposal procedures should be documented to ensure compliance with local regulations. The documentation should consist of information such as the type and quantity of materials disposed of, the date and location of disposal, and the method and location of disposal. Records of these documents should be maintained for a reasonable period.
7. Training:
Training on the procedures outlined above should be provided to all staff dealing with raw materials disposal. The training should be documented, and refresher courses should be provided regularly.
8. Reference:
Relevant local, federal, and international laws and regulations concerning the disposal of raw materials should be consulted when creating and revising this SOP.
