Working with electronic systems―even low-voltage circuit boards―requires strict safety measures. To properly protect yourself and your sensitive electronic components, practice proper lab safety and use the right tools. Here are five essential kinds of lab safety equipment that will protect you as you prototype and build your next project.
1. ESD Protection
Whether you're developing a new PCB prototype or building your DIY desktop, be sure to protect yourself and your electronic devices from unwanted electrostatic discharge (ESD). ESD antistatic tools drain static energy from ESD-sensitive products to help your devices work properly and reduce the risk of uncomfortable or dangerous electrostatic shocks. These tools include:
· ESD grounding mats. Mats are ideal for working on ESD-sensitive equipment, but you can also use them to ground yourself and prevent shocks from energized equipment or electrostatically charged electronics. DESCO's disposable ESD mat is great for on-the-go labs and tradeshows.
· Antistatic wrist strap cable. Tripp Lite's antistatic wrist strap comes with an integrated grounding wire that integrates with the ESD mat to protect the user.
ESD-friendly tools prevent the transfer of energy from the operator to the equipment, which is especially valuable when tools are made from highly conductive materials.
2. Non-leaded Solder
Soldering materials can present a safety risk, since some devices and components contain hazardous materials like lead. Leaded solder is banned in many countries, since soldering with lead creates fumes that can cause lead poisoning. Some flux and solder contains rosin, which―when heated―releases dangerous chemicals that can also be hazardous and cause respiratory problems. Instead of leaded solder, opt for lead-free solder, which is made from various non-lead metal alloys.
3. Proper Ventilation and Hazard Filtering Products
If you're soldering by hand or using a soldering paste, you may be releasing chemicals into the air that can cause respiratory issues. We recommend a desktop carbon filter for small-scale projects. These filters locally ventilate and filter the hazardous chemicals out of the air. However, these carbon filters will reach full absorption and require replacement, so be sure to grab a few replacement filters to ensure your lab stays protected. If you're looking for a larger solution to filter large amounts of solder and other airborne lab hazards, fume extractors like Weller's Zero Smog EL come with adjustable necks to create local extraction. The Zero Smog EL integrates seamlessly with an extraction hood to create safe working conditions over a larger area.
4. Fire Protection
Soldering involves temperatures of nearly 1000 degrees Fahrenheit. If you're not handing and protecting your soldering tools properly, you may be creating a fire hazard. Here are several fire safety tools to keep on hand in your lab:
· Fire extinguisher. Make sure your extinguisher is easily accessible and regularly inspected.
· Silicone Heat Resistant Mat. These mats minimize fire hazards from soldering irons. We recommend using a mat as your working surface for all soldering activity, as it will protect your benchtop surface from overheating and potentially catching fire.
· Soldering iron stand. Store your soldering iron safely to prevent the hot surface from making unwanted contact with a combustible surface.
5. General PPE
As in all hazardous environments, proper personal protection equipment (PPE) is critical. Electronics labs present various hazards―such as 'popping' solder―that can cause eye injuries, so always wear protective goggles in the lab. 3M makes a variety of protective eyewear, ranging from face shields and fully-enclosed goggles to protective shop goggles and shaded sunwear.
If you're one of those deeply curious engineers who wonders what will happen when you put 10A through an epoxy-coated LED, protective eyewear may save you from exploding plastic shards. Ask me how I know.
