Although a total solar eclipse is not a once-in-a-lifetime phenomenon, it is still relatively uncommon, and rarer still for it to occur precisely in your region. However, even if you are fortunate enough to witness such an event, you may not necessarily want to watch it. The reason is simple: solar eclipses can be hazardous to your eyes, especially if you don&#;t take adequate precautions.

Regular sunglasses or even many specialized lenses may not provide sufficient protection, leaving you vulnerable to eye damage. It&#;s essential to purchase the proper safety equipment well in advance of the event. During the lead-up to the solar eclipse that traversed the United States, supplies of specialized eclipse glasses ran out at many stores, including big-box retailers and eyeglass shops, leaving some people scrambling for less-effective alternatives. These included faulty solar eclipse glasses, unverified solar viewers, and even welding helmets.
If you&#;re planning to observe the next significant solar event in your region, be sure to order your safety equipment early and don&#;t settle for partial protection. This article will provide guidance on how to select the appropriate glasses and explain why getting it right is crucial for safeguarding your vision.
Welders understand that the fumes and gases produced from their work can lead to serious illness. The danger and amount of exposure to the welders depend on the type of work being done, the rod, filler metals, base metals, coatings, contaminants, as well as the amount of ventilation and respiration protection.
We simply don't know everything there is to know about protecting workers from welding fumes. However, there are some common precautions that can be taken to protect workers from injury and illness.
Welding fumes are basically a mixture of metallic oxides, fluorides, and silicates. Not so wonderful to be breathing into your lungs by themselves, but since we have to live and work in the real world, there are other considerations such as the paint, rust inhibitors, solvents, and other coatings on the welded metal which can create additional dangers.
With proper precaution, the amount of gas and vapor can be eliminated, or at least reduced to a high degree. Ventilation is always an essential control option. Whether you are ventilating the entire area or can drill down to a very specific confined space, replacing dirty air with clean is often the first go-to procedure. Many shops require ventilation that meets UL specifications such as the RamFan UB20 with ducting.
Another option is respiratory protection. Fumes produced by basic welding of iron or steel can often be blocked by wearing a simple N95 mask such as the 3M N95 Welding Particulate Respirator or as a step up, an N99 mask such as the Moldex Premium Disposable Welding Respirator. Both of these have exhalation valves to keep the mask cool. However, these types of disposable masks are only good for simple welding. The n100 mask is for those who want the highest rated by NIOSH filter efficiency in a mask. It is approved for lead abatement, metal fumes produced from welding, certain radioactive particulate material, and non-oil containing mists.
Once you start arc welding, the ozone created by the electrical arc produces fumes that require a more robust system of respiratory protection. Since the face shields worn to protect from infrared restrict the type of respirator and cartridge or filter that can be used, many welders prefer soft P100 filters like the 3M Particulate Mold Filter P100 because they have a layer of charcoal to absorb fumes and organic vapors and also can block far more of the particles carried on the air. The s can be worn on the 3M Series half-face masks or the 3M Series which is made of soft silicon and is more comfortable when worn for long periods of time.
Even more sophisticated breathing systems exist. The Pureflo Welding Helmet is a powered air respirator with Shade 10 or Auto-darkening features, face, eyes, and head protection. But at a cost. Airline Respirators are also an option, but may not be appropriate for all worksites.
Beyond basic protection, like the N95 masks for simple iron or steel welding, it's crucial to up the ante for more hazardous materials. A study by Rafiee et al. () underlines this, showing that respirators beyond the N95 standard significantly reduce metal particle inhalation. This reveals the crucial need for selecting the right respirator for the job, as it can make a substantial difference in your protection level.
Especially for intense tasks like arc welding, which generates more harmful fumes, opting for advanced respirators such as the 3M Particulate Mold Filter P100 becomes essential. These not only absorb more fumes and organic vapors but also ensure that you're filtering out the smallest of harmful particles. Remember, the right fit and the right filter are key to keeping those welding fumes at bay.
