Protective Glasses for Working with Chemicals

Protective glasses are meant to protect the eyes of the user, not to please the manager or salesmen, nor to decrease the work of eye surgeons.

Which protective glasses to choose shall be clear once the tasks, procedures and the working environment which could jeopardize the employees are thought through. To guarantee sufficient protection, the eye protection equipment must correspond to the standard EN 166.

Choice

If the work involves abrasive substances and liquids (e.g. sand and natron blaster works, gunite device, filler or gun works; work with construction foams, etc.), acids, alkali, disinfectants, rust removals or plant protection, tight protection glasses must be worn which fit tightly against the face and do not allow any volatile substances to reach the eyes. These are goggles which have the best protective properties and a good design. They offer a wide and open field of view; the plastic rubber edge increases the comfort of usability and keeps the goggles tight against the face. Goggles have the perfect size and fit over the regular prescription glasses without making the user feel clumsy or uncomfortable.

It is sensible to use similar protective glasses also during concrete work (also see the section “Protective Glasses”) as it involves chemicals. The so-called concrete milk is alkaline and has a corrosive effect when in contact with the eye. Concrete work is hazardous – when pumping concrete and the hose gets jammed, it will break and concrete components (incl. stones and sand) burst from the over 75-bar pressure and could hit the unprotected eye and damage it permanently.

When looking at the pictures and think about your works and activities, first choices can be made about the protective equipment. Illustrations clearly show the efficiency of different eye protection equipment. In all cases, the paint was sprayed from a distance of 0.5 metres and for 4-5 seconds. Images show – from left to right: prescription glasses, most popular protection glasses and goggles. Results range from eyes that were protected from the worst up to completely shielded visual organs.

Use

If wearing the protective glasses is not mandatory during the entire workday, glasses must still be worn during such tasks which involve chemicals; or if there is a risk that something could hit the eye and damage it.

When glasses become dirty, choose a safe place for removing and cleaning them. Follow the manufacturer’s instructions when cleaning the glasses. Depending on the extent of soiling, use either warm water or a special cleaning agent and a cleaning cloth. Even though the cleaning process does not take much time, the workplace hazards could injure the eyes.

Protective glasses do not last forever. If glasses get scratched or damaged, or if the frames get damaged, the protective glasses should be replaced.
