Question 55
Refer to the following paragraph: “Welding can be hazardous not only to the eyes but also to the lungs. Welders often breathe in gases which are harmful to the lungs. The National Institute of Occupational Safety (NIOS) has called for the use of safety helmets which not only protect the eyes and face but also filter the air which welders breathe in while they are at work. Michael Buckman has invented just such as protective gear called the WindMaker Helmet. A glass faceplate protects the face and eyes. At the same time, the helmet draws in fresh air from behind the welder. The air is filtered by the helmet and drawn to the front for breathing in. A fan near the chin helps expel, blowing away toxic smoke in the work zone. LED lights on each side of the faceplate illuminate the welding job while a thick shroud deflects sparks.” Based on the paragraph above, which of the following is a function of the WindMaker? I. To reduce the danger of eye injuries. II. To reduce the danger of lung infections. III. To give better illumination of the welder’s workspace. IV. To give more effective first-aid in case of workplace injury.
