How can you reduce hazardous chemical use in sample preparation?

2 Choose safer alternatives

The second step to reduce hazardous chemical use is to choose safer alternatives whenever possible. You should look for chemicals that have lower toxicity, flammability, corrosivity, reactivity, or volatility than the ones you currently use. You should also consider using non-chemical methods, such as mechanical, physical, or biological techniques, to achieve the same results. For example, you could use ultrasonic or microwave-assisted extraction instead of organic solvents, or enzymatic digestion instead of strong acids or bases.

3 Optimize your processes

The third step to reduce hazardous chemical use is to optimize your processes and improve your efficiency. You should follow the best practices and guidelines for sample preparation and avoid unnecessary or redundant steps. You should also use the appropriate equipment, tools, and techniques to reduce the amount of chemicals required and to prevent spills, leaks, or losses. For example, you could use microscale or nanoscale methods, closed systems, or automated devices to reduce the volume of chemicals and samples.

4 Store and handle with care

The fourth step to reduce hazardous chemical use is to store and handle your chemicals with care and respect. You should follow the storage and handling instructions for each chemical and ensure that they are properly labeled, sealed, and organized. You should also use the appropriate personal protective equipment, such as gloves, goggles, and masks, and follow the safety rules and regulations in your laboratory. Moreover, you should dispose of your chemicals and waste in a responsible and compliant manner and avoid mixing or dumping them.

5 Monitor and evaluate your performance

The fifth step to reduce hazardous chemical use is to monitor and evaluate your performance and progress. You should keep track of the types, amounts, and costs of chemicals you use and compare them with your baseline or goals. You should also measure the quality and integrity of your samples and ensure that they meet the standards and specifications of your analysis. Furthermore, you should solicit feedback from your colleagues, supervisors, and customers and identify the areas for improvement or recognition.

6 Educate and motivate yourself and others

The sixth and final step to reduce hazardous chemical use is to educate and motivate yourself and others about the benefits and challenges of this practice. You should learn about the latest trends, innovations, and solutions in sample preparation and share your knowledge and experience with your peers and stakeholders. You should also celebrate your achievements and rewards and acknowledge your difficulties and limitations. Most importantly, you should foster a culture of safety, sustainability, and quality in your laboratory and inspire others to follow your example.
