![]() First, turn off all power to the air compressor. Step 2 - Get Readyīefore you can attach a new hose to your air compressor, you must take a few preliminary steps. These will help you attach and remove the hose quickly, making set up and storage more convenient. While you are shopping consider buying quick connect couplers. Once you have all of the necessary measurements it is time to buy the hose. Too long a hose, however, will cause the compressor to lose pressure, making it less efficient. ![]() A longer hose will help you reach across a work area and will help prevent electrical hazards caused by having a long electrical cord. You will also need to jot down the desired length of the hose. ![]() This will help you find hoses designed for your air compressor. Pneumatic power tools shall be secured to the hose or whip by some positive means to prevent the tool from becoming accidentally disconnected.Step 1 - Gather Preliminary Information and Shopīefore you can do anything, you need to jot down your air compressor’s brand name and model number. OSHA.603 paragraph (a)(10): Safety chains, or equivalent means, shall be provided for each hose connection to prevent the line from thrashing around in case the coupling becomes disconnected. Additionally 1926.302(b)(7) states: All hoses exceeding ½-inch inside diameter shall have a safety device at the source of supply or branch line to reduce pressure in case of hose failure.Įxcept where automatic shutoff valves are used, safety chains or other suitable locking devices shall be used at connections to machines of high-pressure hose lines of 3/4-inch inside diameter or larger, and between high-pressure hose lines of 3/4-inch inside diameter or larger, where a connection failure would create a hazard. 302(b)(1): Pneumatic power tools shall be secured to the hose or whip by some positive means to prevent the tool from becoming accidentally disconnected. Retire a hose from service before a blow out occurs. Education should include how to conduct a thorough inspection and what to do in the event that an issue is found. Ensure that all operators are aware of the purpose of the system’s safety components and how to properly install them. Learning that whip check or choker cables will not keep a hose in check if they are installed too close to the hose coupling could be the difference between injury and a quick repair. Understanding that coupling disconnection can be caused by vibration could increase the value of safety clips to the operator. If the hose coupling twists inside the hose or any of the hose shank is exposed, repair or replace the assembly.Įducation is equally important with a well designed hose system. Check that any field repairs have been done correctly and are holding up well. ![]() Ozone and jobsite abuse will wear down a hose over time. Inspect the condition of hose assemblies and all other items in the system regularly. Higher pressure and sleeve retractable coupling options are available. Chicago type couplings are rated at 150 PSI regardless of the higher pressure rating stated on most air hose. Make sure that the hose coupling is secured using safety clips, and rated for the peak pressure of the system. If they are installed at the hose coupling, the hose may slip out of its grasp rendering it useless.Ī properly selected hose coupling, and a well assembled brand name air hose round out a well designed safe pneumatic system. Correctly install the devices by pulling them fully extended down the hose line rather than around the hose coupling. Proper selection includes ensuring that the pressure rating of the cable is beyond the peak system pressure, and that the size range fits the hose properly. These devices, when selected and installed properly, will hold the hose in ‘check’ until all air escapes. Hose safety whip check cables, choker cables, or nylon safety restraints, should be installed at every hose connection, including at the air source and the hose to tool end. Once the air beyond the check valve escapes, the hose lays limp rather than hazardously flying around until it can be captured. ![]() A surge in air volume signals that a hose is severed. Luckily there are a number of safety products available to help to mitigate the risk from these hazards.Ī complete hose safety system includes a number of products as well as proper education and regular inspection.Īn OSHA compliant safety check valve at the air source (compressor, manifold, or air receiver) will sever the air flow if a surge is recognized. A hose coupling blow-out can become a deadly projectile. An unchecked out of control hose can be dangerous to the operator and to bystanders alike. Pneumatic tool supply hose, or Jackhammer Hose, can add risk of hazards and injury to the job site. ![]()
