1 Know your samples

Before you start preparing your samples, you should know what they are, what they contain, and how they react. Some samples may be flammable, explosive, corrosive, toxic, or reactive with other substances. You should check the safety data sheets (SDS) of your samples and reagents, and consult the relevant literature or experts if you have any doubts. You should also label your samples clearly and store them properly to avoid confusion and contamination.

2 Choose the right method

Depending on the type and purpose of your analysis, you may need to use different methods of sample preparation, such as digestion, extraction, dissolution, filtration, or homogenization. Each method has its own advantages and disadvantages, and may require specific equipment, reagents, and conditions. You should choose the method that is most suitable for your sample and analysis, and follow the standard operating procedures (SOPs) or instructions carefully. You should also avoid using incompatible or expired reagents, or excessive amounts of reagents that may cause overheating, pressure build-up, or violent reactions.

3 Use the appropriate equipment

The equipment you use for sample preparation should be designed and maintained for the specific method and sample you are using. You should check the equipment for any defects, leaks, cracks, or malfunctions before and after each use, and report any problems immediately. You should also use the equipment according to the manufacturer's guidelines and safety precautions, and never modify or improvise with the equipment without proper authorization. For example, if you are using a microwave digestion system, you should use the appropriate vessels, caps, and rotors, and follow the recommended temperature, pressure, and time settings.

4 Wear the necessary protection

Personal protective equipment (PPE) is essential for preventing injuries from fires and explosions during sample preparation. You should wear the appropriate PPE for the method and sample you are using, such as gloves, goggles, lab coat, apron, and face shield. You should also make sure that your PPE is clean, intact, and fits well. You should never wear loose or flammable clothing, jewelry, or accessories that may catch fire or interfere with your work. You should also tie back long hair and avoid contact lenses that may trap chemicals or vapors.

5 Follow the best practices

When preparing samples, there are some general best practices to prevent fires and explosions that should be followed. This includes working in a well-ventilated area or a fume hood to avoid inhaling or accumulating flammable or toxic vapors. Additionally, it is essential to keep a safe distance and use a shield or barrier when working with high temperatures, pressures, or explosive materials. Moreover, a spark-proof or explosion-proof device should be used when dealing with flammable or volatile substances. It is also important to keep a fire extinguisher, a fire blanket, and a first aid kit nearby and know how to use them in case of an emergency. Furthermore, any spills, residues, or waste should be cleaned up promptly and disposed of according to the regulations. Finally, all accidents, incidents, or near-misses should be reported to the supervisor or safety officer and lessons should be learned from them.
