And guess what's under that veneer layer: urea formaldehyde, more than likely.
Do what you want.
People who do woodworking on a regular basis actually do know enough about safety precautions to be wearing a respirator or at least a dust mask and use dust collection as they work. You have to give people who do a lot of woodworking some credit for knowing the basics. He is obviously not a beginner at it.
Gordon you do not want to take me on head to head with who is the more educated on safety when using chemicals. But you seem determined to do that so....
Not only am I a woodworker when I was at Boeing my job as a working lead included the responsibility for the hazardous waste and hazardous chemical program for a 600 employee work group. In addition to my own work group I was on corporate teams focused on those issues.
I had to be able to read and understand information from MSDS data as well as be able to obtain from those documents the knowledge of all of the required safety precautions for its use such as respirators, gloves, ventilation, toxic sentization prevention measures, etc. I also had to know to how to safely store and dispose of the over the over 1,000 different paints, adhesives, epoxy, solvents, etc, etc that were used in our production area.
I myself actually developed and wrote the current Boeing corporate policy on how to effectively reduce the amount of hazardous material waste in workshop areas without spending a lot of money.
In the inspections done by corporate health and safety and the EPA the very large building for which I oversaw everything related to chemicals used within it was the only one in the Everett facility with zero violations for health and safety as well as EPA and fire department regulations. So just maybe I actually do know what I am talking about because it was a profession for which I received more than a fair amount of education and training versus people who just find stuff on the internet. I neither over react or under react given the materials I am working with.
As to the formaldehyde issue. They don't typically use that class of adhesives in high quality marine plywoods, they are using other types of adhesives that are more reliably waterproof for preventing delamination in wet conditions. Part of the reason the cost of those plywoods is so high is because of those special adhesives versus inexpensive formaldehyde containing adhesives. I have been buying and using those types of marine plywoods purchased from specialty marine wood suppliers for the last 20 years so of course I had a vested interest in knowing what kinds of adhesives they were put together with.
In the last decade the lumber industry as a whole has moved away from those formulas of adhesives that have formaldehyde due to litigation and also because of strong consumer demand for more eco
friendly products. Even the stores prefer not to have it in their warehouse spaces since the off gassing is strongest when the product is newly made and they have to take care because of legal obligations for the health and safety of their employees.
I am wearing my 3M brand, properly fitted to my size of face, cartridge respirator today because I am removing an area of the old plywood floor in my Campster
. I also have long sleeves on my shirt, long pants and am wearing leather shoes. I will take a shower when I finish and wash my clothes separately from other laundry
