My organisation handles bulk waste solvents.
I am of the opinion that operators should not wear contact lenses as a spill/splash involving solvent in the eye may result in the solvent attacking the lens and damaging the eye.
I am seeking guidance that either supports or opposes my opinion.

contact lenses should be avoided while working in chemical plants.As there are safety goggles are available which can fit over the glasses.

Agree- remember even if the contact lense is not damaged, irrigation of the eyeball may be hindered by the contact lense.

Surely if someone is wearing safety goggles then they aren't going to get splashed in the eyes - so why can't they wear contact lenses?

Try leaving some plastic things near the fumes from various nasties and see what happens? Fumes will penetrate under face masks, ventilated goggles etc, etc.

I would suggest that if vapour from chemicals are entering peoples eyes and affecting contact lenses then they would most likely also cause irritation to people not wearing contact lenses - the control measures would not be adequate.

I agree with Simon. If you are not protecting adequately to prevent irritation/splashes to contact lens wearers you are not protecting properly.
Having a lens in won't prevent proper irrigation, generally the lens will just fall out as soon as water etc goes into the eye if it hasn't already been taken out. Having a lens in can also provide protection as the substance will fall on the lens not the iris

The contact lens issue has been discussed previously.
Refer my contribution to :-
http://www.iosh.co.uk/in...iew&forum=1&thread=28005
The "myth" concerning the dangers associated with wearing contact lenses in a chemical environment has been largely countered by several professional bodies, including the American Chemical Society (ACS).
The ACS, because of the ever-increasing use of contact lenses and the benefits they provide, have studied and reviewed the issue.
The ACS is of the consensus that contact lenses can be worn in most work environments provided the same approved eye protection is worn as required of other workers in the area.
All details at:- (Please copy & paste the links to read both articles-It appears that I cannot reproduce extracts on this IOSH website as there is a blanket copyright restriction on the free access part of the ACS website, except for research etc!)

The main risk to contact lense warers in industrial settings is through welding. There have been cases where a microwave effect has occured between the lense and the eye on exposere to uv light. in one case the contact lense was welded to theeye which caused the cornea to be removed when the lense was taken out.

I am astonished and dismayed that any member of the Institution still believes the welding/cornea story. Apparently the legend has been around since 1967 and has been described as being false and impossible by nearly every reputable medical and scientific source - see http://www.snopes.com/horrors/techno/cornea.asp
We do have a responsibility not to repeat these urban legends.
