It is interesting to note that the answers below reflect different responses to the same question. - Ralph Date: Thu, 11 Sep 2003 08:03:45 -0400 From: richard rydzaEvaluate the hazard and then select the correct PPE. if chemicals are used and there is a potential for splash, yes then a goggle with seal is appropriate. now if there is general work where the splashing hazards do not exist, i would recommend high or low impact eye wear Low or high impact depends on the hazard on the possible flying object.

Safety glasses even with side shields do not afford equal protection as goggles do. I am a Chemist and remember, at school, being required to wear the goggles which sometimes steamed up. At my current position I often use a shield between me and any dangerous mixing. Bill Jackson Manager, Laboratory Philadelphia Gas Works 215 787-4839 === Date: Thu, 11 Sep 2003 08:25:04 -0400 From: "Sheets, M. Pamela" Goggles should be worn when there is any chance of splashing corrosive liquids. ANSIZ87.1a-1991 is the standard to reference. Your chemistry professor answered his/her own question when he/she acknowledged goggles are better than safety glasses due to the seal. === Date: Thu, 11 Sep 2003 08:29:48 -0400 From: "Peart, Charlyn M" Subject: RE: [DCHAS-L] Laboratory eye protection We require safety glasses at all time and require goggles and/or face shield depending on the task that is being performed - splash or vapor hazard. === Date: Thu, 11 Sep 2003 08:57:10 -0400 From: ILPI >It is true that the goggles provide the best protection because they >form a seal around the entire eye, That's the answer as far as I am concerned. Let's assume that you get a splash on your face. Thanks to gravity, that material is going to dribble down into the eyes whereas properly worn goggles will generally prevent that. Further, in the event of an explosion, goggles will do a better job stopping a glass fragment that is coming in at a vulnerable angle. Finally, even good safety glasses can occasionally slide down the bridge of the nose, leaving a vulnerable gap for splash particles. I never allowed undergraduates to use safety glasses in lieu of goggles. I remember a classmate from my third year of college who decided to pour concentrated nitric acid from a large bottle directly into a 10 ml graduate cylinder. He put it the cylinder on a bench and then bent down with his head sideways to read the meniscus as he poured, "balancing" the lip of the bottle on the top of the cylinder as he did so. He was easy to spot in class for the next few weeks - big yellow stains on his face. Luckily, his goggles saved his eyes. With safety glasses he almost definitely would have been worse off. I have never had much problem with grad students or faculty wearing safety glasses over goggles as their experience usually (but not always) tends to minimize the danger of accidents like that. Goggles are, in my opinion, definitely safer for all parties, of course, and faculty wearing them just like the students is teaching/leading by example. A final reason is that it makes it easy to spot who is a student and who is an instructor (wink) and goggles give you that great geek hairstyle after lab... Rob Toreki == Date: Thu, 11 Sep 2003 08:58:45 -0400 From: "William Munsey" This may be part of it: Safety goggles provide splash protection from the direction splashes are most likely to come: below the eyes. If there are glasses which provide protection from below as well as from the sides and above, I am not aware of them. Wiliiam Munsey Professor of Chemistry Blue Ridge (VA) Community College munseyw (at) br (dot) vccs (dot) edu == Date: Thu, 11 Sep 2003 08:52:03 -0400 From: "Novodoff, Jack" Linda, Tell you faculty member that the indirectly vented goggles provide the best eye protection for the student whereas safety glasses do not prevent liquid from running down into the eyes if there is a full face splash. In addition, if there is an accident and the student has eye injures, the university and the faculty member become legally liable for not providing the best personal protection for the student. The students now are very litegation aware and will sue the university and the faculty member. If you university is like the UM, the faculty member, by not enforcing the official safety policies of the department, will not have the legal protection of the university. He will be on his own. I hope he has several million dollares in personal liability insurance.

Safety goggles provide a seal around the eyes which serves to protect against splashing liquids or organic vapors. Safety glasses with side shields protect against flying objects, but will allow liquids to run down into the eyes should it be splashed on someone's forehead, etc. === From: "Shields, Jefry (JE)" Date: Thu, 11 Sep 2003 09:56:01 -0400 It's the splash protection that goggles provide that glasses don't. If a splash of chemical solution strikes a person in the face, goggles will prevent access of the solution to the eyes whereas safety glasses will not. This is not the direct splash as both will provide this protection, it's the flowing of the solution once it's on your face that goggles will better protect against. Jefry === Date: Thu, 11 Sep 2003 09:59:37 -0400 From: Dan Crowl Linda, I would recommend against requiring safety goggles in the lab. They are uncomfortable and result in interesting rings around your eyes. I suspect that if you require goggles, students and faculty will decide that the policy is "stupid" and not wear them all the time. Since you already received an inquiry, I suspect this process is already underway. In our labs, we require regular safety glasses at all times in the lab, but also require goggles for any operation involving chemical transfers or other operations where liquids or other material might be airborn. Of course, the person has to use their judgement on when to use goggles. The goggles can fit right over the safety glasses. Just my opinion.... Dan Crowl Michigan Tech == From: "Diane Amell" Date: Thu, 11 Sep 2003 09:32:01 -0500 The reason is splashing. Even with the extra shields, splashing can still occur. (And, let's face it - safety glasses can slip out of position, whereas goggles have the headstrap that keeps them in place.) ANSI Z87.1, which covers both occupational and educational use of eye and face protection, requires goggles and does not recommend the use of safety glasses when working with acids and other chemicals. - Diane Amell, MNOSHA === From: "Vernon, Russell" Date: Thu, 11 Sep 2003 07:33:29 -0700 Dear Linda, As a good friend once told me... "The best form of eye protection is that which is worn." When I worked at UC San Diego in the Chemistry & Biochemistry undergraduate labs we noticed how well the foreheads of the students were being protected with their goggles. We began allowing safety glasses and amazingly enough even the Instructors and TAs began wearing them! Our 'rule of thumb' was "whenever a splash hazard existed" goggles were required (sometimes with a face shield). It all depended on the hazard of the substance, the volume and the procedure (sometimes the technique too!). So, I recommend allowing safety glasses. However, evaluate different glasses and specify the students & other obtain only the ones you have determined are the most suitable. My 2 cents...

Splash goggles are required in all teaching laboratories. I've had some nasty accidents in which the student would have suffered significant injury had they not been wearing goggles. B.C. Hinshaw === Date: Thu, 11 Sep 2003 11:39:51 -0400 From: "George H. Wahl, Jr" Chemistry labs are notorious for being the home of dangerous spills and splashes. Only approved Chemical Splash Goggles provide adequate protection. "Safety Glasses" are probably OK in machine shops, woodworking areas, etc. where the source of a flying fragment is usually directly in front of you. However, in CH labs, splashes may come from many different doirections. You might consider keeping ALL faculty teaching students who attend your labs informed of lab safety policies. George H.

OSHA requires safety glasses for most lab situations. Our rational is two-fold. First, will the users switch from the safety glasses to goggles when the situation requires them? Will they perform a procedure which does not require goggles but has a significant opportunity for a splash to bypass the glasses? Second, are we willing to take the liability risk of someone not wearing goggles? If your answers are generally no, yes, no then goggles are in everyone's best interest. This might be called a "best practice" rather than a regulation. On the personal experience side, after splashing toluene into my eye when in industry, I would not want anyone to get anything into their eyes. Paul Weller Science Laboratory Manager-Chemistry Elon University === Date: Thu, 11 Sep 2003 12:16:13 -0400 From: "Mary M. Cavanaugh" We just dealt with exactly the same issue. Goggles are required if there is a chance of liquids or dusts splashing into the eyes and the liquid/dust is something that would cause harm to the eyes. In my experience, that means virtually any lab where wet chemistry will take place requires goggles. Safety glasses, whether they fit close to the face or not, are ONLY FOR IMPACTS. If impacts are the only hazard in a particular lab (for example many of our physics labs), then by all means safety glasses are appropriate. I can provide you with citations from the regs, the preamble, and the applicable ANSI standard if you need that level of justification. Just give me a call. On a related note - there's a very good chance that the resistance to goggles is because the cheap ones everyone issues in academic labs fog up like crazy. Spend the extra dollar for anti-fog coating and a lot of your resistance will melt away. -- Mary M.

The safety glasses are good to protect against projectile contact. However, they do not provide adequate protection against liquid splash. Sean Riley, CHMM HSE Manager Polaroid ==== From: "Rebecca Schafer" Date: Thu, 11 Sep 2003 13:16:57 -0500 Safety glasses do not provide adequate splash protection for the eyes regardless of the length of the shields or other protective devices. Chemical splash goggles, (indriectly vented) are the best protection for splash hazards because they seal against the users face, preventing chemicals from reaching the eye. If you are concerned with the students not wearing them because they fog, UVEX makes the Stealth Goggle. We use that at our company and it is comfortable and the lenses are replaceable so they can be used for long periods of time. They also don't fog as much as your traditional goggle. There is a video from the 1980's that demonstrates the differences in eye protection. Its a very useful tool for an educator as well as for the students because it provides real examples of what can happen when not using the proper eyewear. "Eye and Face Protection in the Chemical Laboratories" was produced by the National Society for the Prevention of Blindness. You can purchase this video from the Laboratory Safety Institute for $59. Or if you are a member, you can borrow it from the lending library. Rebecca Schafer Environmental Health and Safety Coordinator Cerilliant Corporation 512-310-5185 === From: I can only speak for research labs in industry. Using goggles is appropriate for specific hazardous conditions. I suspect because the target group is students that the desire is to be "extra safe." Safety glasses (with shields) are appropriate for persons not running hazardous experiments in a lab. The definition of "hazardous" becomes one issue and the judgment of students/TAs as to what level of PPE is appropriate becomes another. Goggles have their own issues that have to be considered when deciding when to use and replace them. In hot, high humidity environments, they can be very uncomfortable. The "age" and must be replaced and are more costly than Safety Glasses. PPE vs level of hazard Visitors glasses - low hazard areas - lab walk throughs where length of stay is low ANSI Safety Glasses (w/shields) - low to medium hazard areas in labs including in lab lectures or demos by an instructor. Goggles - medium hazard areas where the hazard of eye contact with chemicals is elevated. Student run experiments are an appropriate use. Face shield over Goggles or Safety Glasses - medium to high hazard where risk of explosion/implosion is elevated Safety glasses (with shields) need to be ANSI approved for persons that work in labs. "Visitors safety glasses" may not be so rated depending on the model. We have chosen to only use ANSI glasses for this function to avoid the confusion of 2 types of glasses. This is my opinion. --Bill --------------------------Mr.------------------------------------------- L.
