![]() ![]() Restraining hoses and piping Hazards associated with hoses or piping and their connections operating under pressure are mainly the result of failures caused by leaks, pulsation, vibration, and excessive pressure. Government Agencies in Canada have standards and use of whip checks base upon A false sense of security may result in injury or death when persons reduce their level of caution as they believe they have effective safeguards. Similar to all types of controls for worker safety, using the wrong type of equipment can be just as dangerous as if no controls were applied. polypropylene) to stainless steel cables. Are they the proper fittings for the application and hose selected? Whip checks come in a variety of materials ranging from natural fiber and synthetic materials (i.e. Of course it is imperative to know the coupling system for the hose connections. What is the maximum pressure including surges (or, maximum vacuum) that this hose assembly will be subjected to? Always rate the maximum working pressure of your hose assembly by the lowest rated component in the system. Check for: Abrasive materials, chemical compatibility, etc. Is it a pressure application? Is it a vacuum (suction) application? Is it a gravity flow application? Are there any special requirements that the hose assembly is expected to perform? Is the hose being used in a horizontal or vertical position? Are there any pulsations or vibrations acting on the hose assembly? Is the system a hose-to-hose connection or a hose-to-tool end configuration? What is the media/material that is flowing through the hose assembly? Being specific is critical. It is important to know how is the hose assembly is actually being used. What is the temperature range of the media (product) that is flowing through the hose assembly? It is also useful to having an understanding of the temperature range of the environment that surrounds the outside of the hose assembly. Also it is important to know the overall length of the assembly required. Know the specific size requirements: Typically, this means knowing the inside hose diameter (I.D.) as well as the outside diameter (O.D.) of both ends of the hose. ![]()
