3. Water Supply and Wastewater Disposal

The quality of water used in the manufacturing process is a critical component of GMP standards. All water used in the production of cosmetics must be potable and free from contaminants. Moreover, proper measures must be in place for the disposal of wastewater to prevent any environmental hazards or health risks associated with the water used in production.

A well-organized drainage system should be established to handle wastewater disposal in compliance with environmental regulations. The factory must ensure that no harmful substances are released into the environment, and water used during production must be disposed of in a responsible manner to avoid contamination of surrounding areas.

4. Health and Sanitary Conditions of Staff

All workers in the cosmetic manufacturing facility must be free from contagious or infectious diseases, ensuring that the workforce does not pose a risk to the quality of the products being produced. Workers should be provided with uniforms, gloves, headgear, and masks to maintain hygiene during production processes. Furthermore, the facility should provide adequate washing facilities and cleanliness protocols for workers to ensure their personal hygiene is maintained.

The health and safety of the staff should be continuously monitored, with regular medical checkups and a designated space for first aid and emergency health services. This practice not only supports worker well-being but also contributes to the overall safety and quality of the cosmetics produced in the factory.
