Solution

48. A Material Safety Data Sheet (MSDS) is designed to provide both workers and emergency personnel with the proper procedures for handling or working with a particular substance.

49. Leather provides superior protection for welding or metal working application. Leather protective clothings include leather welding jacket, leather cape sleeve, leather bib overalls, leather bib apron etc.

50. Shears are mechanical metal cutting machines used in welding shops. They can be either hand operated or by powerful motors. Shears are preffered over thermal cutting because of the wide variety of metals it can cut and also the metal is not heated.

51. A grounded power tool has a three-prong plug on it with a ground pin which, when plugged into a properly grounded outlet, connects with a wire which is physically connected to the ground circuit. The grounding wire carries any current that leaks past the insulation of the tool.

A double insulated tool has an extra layer of insulation that eliminates the need of three-prong plug and grounded outlet. These tools have two-prong plug.
