I agree that we shouldn't adopt a false sense of security and think that a face shield makes us somehow invincible. It would be a good idea for a class or program on safety to stress the fact that no piece of safety gear gives us license to ignore good judgement. In my opinion, a good "rule" to always follow is that we should assume an attitude at the lathe as though we are wearing no protective gear rather than an attitude of, "I am armored up and ready for battle". Hopefully, we will then also use protective gear that is appropriate for the task at hand. The one area where I am unclear of your meaning would be in your statement, ".... recommend we should take preventative measures first. I feel the face shield is the last resort, after all other measures have failed it's the only thing between you and bodily harm." My first reading led to to interpret this as something like. "faceshields are not very effective and therefore unnecessary unless we expect something to happen". After mulling it over a bit, maybe you are saying that we should take all prudent measures to assure that we are doing things safely including wearing a faceshield just in case our other precautions weren't enough. I'll have to agree with George that we can't ever prove that wearing a faceshield reduced the severity of an injury, but we can be sure that it didn't make things worse. Since there have been a number of comments regarding AAW safety guidelines, I will share my opinion -- would it be likely or reasonable or prudent for the AAW to issue a guideline to the effect that, "faceshields are really over rated and practically useless and, therefore, we see no point in using them". Since the AAW lacks the technical wherewithal to make such a statement, it ain't gonna' happen. I have also occasionally read misinformed comments on the forums or talked to woodturners who "blame the government" for safety regulations. First of all, the safety standards for eye protection as well as other protection come from ANSI safety standards which are industry developed standards. It just happens that OSHA and their counterparts in other countries adopt these standards. Before we go blaming some entity for having unwanted restrictions placed upon us (or even the mere suggestion that we ought to use certain safety gear), these safety standards are required to be followed in industry, but we woodturners are completely free to make our own choice. More about faceshields -- not all are created equal, but if we go to the local woodworking emporium or big box home improvement store, we will find a wide assortment of faceshields at varying prices and not much to help us decide which one is better. Most of us already know that those faceshields that meet ANSI industry standards will be marked with "Z87" on the polycarbonate shield. If you have done much searching, you may have also found that some of the polycarbonate shields are only about 1/32" thick and others as thick as 3/32". It turns out that faceshields qualified to Z87 standards have different requirements depending on the application. I was too cheap to fork out $57.00 to download the ANSI standard, but I found information on various sites that addresses some questions that we might have. Here is a simple summary of what ANSI Z87 does:The ANSI Z87.1 standard sets forth requirements for the design, construction, testing, and use of eye protection devices, including standards for impact and penetration resistance. All safety glasses, goggles, and face shields used by employees under OSHA jurisdiction must meet the ANSI Z87.1 standard. The eyewear standard includes the following minimum requirements: Provide adequate protection against the hazards for which they are designed Be reasonably comfortable Fit securely, without interfering with movement or vision Be capable of being disinfected if necessary, and be easy to clean Be durable Fit over, or incorporate, prescription eyewear Many manufacturers of sports eyewear and other protective eyewear not used in a work environment also comply with the ANSI Z87.1 standard. If you need protective eyewear of any kind, look for products that comply with the ANSI standard or consult with an optometrist, ophthalmologist, or optician before purchasing. I found a very good FAQ pdf document on the MSA site that explains some of the various categories for eye protection equipment: MSA Frequently Asked Questions about Z87.1 - 20120 Additionally, I found the following pdf on the 3M site: 3M Information on Z87.1 - 2010 Finally, I found the following pdf on the Uvex site. It pertains mainly to eye wear, but there is some useful information that can be extrapolated to faceshields: Uvex Information on Z87.1 What can be gathered from the above information is firstly that there is no specific category that correlates directly to woodturning. Additionally, the standard is for eye protection for a variety of work environments, but does not specifically address things like "crash test dummy" type of impacts. Some faceshields are rated only for protection against dust and small particles. The most stringent requirement uses a .25 inch steel ball being fired at 150 feet per second into the shield. There is also a heavy mass low velocity impact test that meets a somewhat lower level requirement for impact. Faceshields are not like air bags -- they are not kinetic energy absorbing devices. If a bowling ball size piece of wood whacks you in the head at 50 MPH, the faceshield might help to lessen the trauma by spreading the impact over a wider area, but your head is still going to take the full brunt of the kinetic energy. Before the days of seat belts and air bags, a lot of people died as a result of windshield impact head injuries in 35 MPH accidents. Moral of the story: make absolutely certain that what you are doing is safe because there is no safety gear that is going to save you from a major blow to the head. Pilots go through detailed preflight checklists before every single flight -- is there anything wrong with woodturners doing the same?
