Eye protection safety glasses

Eye protection — safety glasses or goggles - is mandatory whenever any pyrotechnic composition is being prepared or tested. Necessary equipment includes a mortar and pestle, a laboratory balance, a soft bristle brush, several 2-3 inch lengths of fireworks-type safety fuse (available from many hobby stores), and a fireproof stone or composite slab on which to conduct burning tests.

Eye protection Safety glasses with side shields or chemical goggles must be worn. 

Protective equipment and clothing can include eye protection (safety glasses or face shields), skin protection (clothing, gloves, shoe covers), self-contained breathing equipment, and/or forced-air ventilation (fume hoods). 

Eye protection Safety glasses, goggles, face shields, etc., used to protect against physical, chemical, and nonionizing radiation hazards. 

Eye wash fountains and safety showers for emergency use must be installed in all work areas where chemicals are handled. The locations, types, and operation of these safety devices are controlled by OSHA regulations. Immersion of the eye or full body in water for a full 15 min is critical when a chemical splash on the individual occurs. Treatment by a physician for any residual effects of the chemical is then necessary. The protection of the eyes with safety glasses equipped with side shields or better chemical worker goggles is very important for all workers around or handling any chemical. Protective clothing as recommended by the MSDS is important for the worker exposed to large quantities of the solvent. 

Tertiary Amine Catalysts. The Hquid tertiary aHphatic amines used as catalysts in the manufacture of polyurethanes can cause contact dermatitis and severe damage to the eye. Inhalation can produce moderate to severe irritation of the upper respiratory tracts and the lungs. Ventilation, protective clothing, and safety glasses are mandatory when handling these chemicals. 

Lachrymator A lachrymator is an irritant that causes tearing (watering of the eyes). Examples include onions, tear gas, and pepper spray (capsaicin). Some typical lachrymating chemicals are thionyl chloride (SOClj) and acrolein (CHj=CH-CHO). Certain chemicals may say lachrymator on the label so treat these with respect. Use these only in a fume hood. Goggles or safety glasses are not adequate protection for lachrymators, because the fumes can still reach your eyes directly or through inhalation.

Lenses for safety glasses are made from highly impact resistant plastics such as modified acrylics and polycarbonate. They will resist puncture from flying objects and offer the exceptional eye protection. They can be molded to prescription requirements. 

Eye protection is mandatory for almost all types of laboratory work. A wide selection of safety glasses and goggles is available from suppliers of safety equipment, many especially designed for specific purposes. There are official specifications for such glasses, and it is unwise to buy any w hich are claimed to be as good as the ones guaranteed to meet those specifications. 

It was found, when an attempt was made to conduct ship trials that the paint applier would be required to wear long sleeves, gloves, safety glasses, and a protective face shield. It is also a requirement that an eyewash fountain be nearby. These requirements were imposed because acrylates are skin, eye and respiratory tract irritants, but the problem lies mostly with the acrylated reactive diluent rather than with the acrylated resin (2,3). To avoid these problems, tests have been performed with use of trimethylolpropane trimethacrylate (TMPTMA) as a replacement for TMPTA. TMPTMA has been shown to be much less of an irritant than TMPTA, and is used in dental restorations.
