* V-Gard propionate visors provide impact protection, and are good for those applications where chemical splash hazards also exist * They offer increased impact protection and superior optical quality over acetate visors. * Being moulded makes them optically correct, and helps ensure they maintain good visibility and reduced eye fatigue.* Their chemical and heat resistance is better as they are thicker and not as stressedas flat visors. * MSA10115855 can be worn in combination with helmet mounted ear defenders and easily fit to the V-Gard Browguard, MSA10127061, but is not compatible with MSA chingards. * The visor dimensions are 203 x 432 with a thickness of 2.5mm* The visor conforms to the following:EN166:2001 Personal Eye Protection (1B 3)1 Optical class 1 for permanent usageB Medium energy impact protection (B = 120 m/s)3 Protection against droplets and splashes of liquids
