Elastomeric respirators may be used to protect against welding fumes. [45] [5]: Box2-1 Different welding processes may produce different fumes, both particles and gasses such as carbon monoxide. Oxygen displacement by otherwise-harmless shielding gasses is also a risk. [46] [47] A self-contained breathing apparatus may be needed. [45]
Photokeratitis or ultraviolet keratitis is a painful eye condition caused by exposure of insufficiently protected eyes to the ultraviolet (UV) rays from either natural (e.g. intense direct or reflected sunlight) or artificial (e.g. the electric arc during welding) sources. Photokeratitis is akin to a sunburn of the cornea and conjunctiva.
In 1984 it trialled the British Mk. 6, the American PASGT and the Israeli OR402 composite helmets to determine the best characteristics of form, fit and ballistic protection. A concept design was developed and the Barrday Co. of Cambridge, Ontario , received a contract to produce over 2,000 Spectra helmets between 1988 and 1990 for ballistic ...
The MannGlas "Digital Eye Glass" welding helmet uses cameras and high-dynamic-range imaging to augment the user's view in dark areas and diminish it in bright areas. Art installation illustrating the mediated reality concept. First we display what's really there, and then this allows a computer to be inserted into the "reality stream" to modify it.
By 1956, helmet sales were far above projections. This resulted in the formation of the Bell Helmet Company as a subsidiary of Bell Auto Parts.
