A safety gadget is a system of restraints that prevent the wearer from falling from a height. By wearing the belt or harness, the risk of injury from a fall is greatly reduced. The gadget allows the user to attach themselves to a stationary object, therefore ensuring they will not hit the ground in the event of a fall. Falling from a height is one of the most common causes of personal injury in the workplace, so it is very important to make sure you are properly equipped when working up high.
An emulsified thixotropic bitumen protective coating is known as a polycoat. When the coating dries, it forms a black, flexible protective film. The finished film creates a tough barrier to vapor transmission.
A specialized, often hand-held, power tool used for cutting hard materials, ceramic tile, metal, concrete, and stone is known as a disc cutter. This tool is very similar to an angle grinder, chop saw, or even a die grinder, with the main difference being the cutting disc itself (a circular diamond blade, or resin-bonded abrasive cutting wheel for a disc cutter vs. an abrasive grinding wheel for an angle grinder). This tool is very effective in cutting very hard materials, especially when compared to hand tools.
