Hoses inspection

Are hoses inspected and renewed periodically to avoid breakage ... 

Monitor performance and documentation of the appropriate HAZMAT inspections and tests, including hose inspections and emergency remote checks. 

Preventive maintenance on vital equipment, such as tractor units, tanks, pumps, hoses, hard arms, pipelines, and mooring facilities, should be properly scheduled, carried out and documented. This program should be separate from the regulatory inspection. Verify from records. 

Insulating flanges to be inspected and tested at intervals not exceeding one month to ensure the insulation is clean and in good condition. Resistance should be measured between the metal pipe on shore side of flange and the end of the hose or metal arm when freely suspended. The measured value should be at least 1000 ohms. 

Before first use hoses to be inspected visually internally and externally and tested at proof pressure. Repeat at least annually and include check on electrical resistance. The resistance of the complete assembly should be not more than 15 ohms, unless the hose is intended to be non-conducting when resistance should be at least 25 000 ohms. Inspect hose daily when in use. Hoses used at monobuoys should also be hydraulically tested. 

All hoses should be inspected and tested regularly and marked to show that they have been approved for use. A good practice is to change the color of the label every 6 or 12 months. This incident is a good illustration of the way both operators and managers become so used to the hazards of process materials that they fail to establish and maintain proper precautions. How often had the wrong...

The design pressure of the test heads and piping, and the rated pressure of hoses and valves in the test manifold, shall be no less than the anticipated test pressure. All equipment should be inspected prior to the test to determine that it is in satisfactory condition. 

Conduct an inspection of petroleum refinery systems for leaks. For example, check hoses, pipes, valves, pumps, and seals. Make necessary repairs where appropriate. 

Placement of detectors should consider the need for protection from physical damage, weather effects (snow, icing, wind-driven rain, or dust), or direct water hose spray during an area wash down. Detector placement should also allow safe access to perform required periodic testing and inspection. Typical approaches to flammable gas detection layout are ...

Every five years, all hoses should be tested to 1 times the container pressure at 130°F (54.4°C). Also, every five years the cylinders should be inspected per DOT requirements. For containers in continuous service, a visual inspection per CCA C-6, Standard for Visual Inspection of Steel Compressed Gas Cylinders may be conducted. The cylinder does not need to be emptied and cylinder should not be stamped. 

Inspect hoses. Tighten all hose connections, including those to the expansion tank, to protect against coolant loss. 

Because of the chemical activity of Metraxt, the equipment used for application and vacuuming requires routine inspection and maintenance. Hoses and gaskets will have to be periodically inspected. Washing the foamer, its hoses and gaskets with soap and water and rinsing with water is recommended after each use to extend hfetime. 

The equipment used for chemical application and sampling is inspected. This is usually a casual inspection. If the equipment is clean, the hoses and belts appear to be in good condition, and equipment is stored properly, the investigator probably takes proper care of his equipment. The maintenance records of the equipment are checked. 

During this inspection the contractor recognized that additional fiberglass work was required. These repairs would require grinding to properly finish one of the field made joints within this header. The contractor generally used a pneumatic grinder for these type of repairs and this chemical plant was equipped with many compressed air utility stations which could be connected to nominal 3/4-inch (1.9 cm) hoses. 

Any hose used to transfer a liquid, including refrigerants, that has an agency-reportable quantity listed for a spill. It does not include normal utility hoses such as steam, water, nitrogen, and air. It does not include hoses that are supplied by a contract carrier. It does not include hydraulic hoses or other such hoses that are permanently mounted as a part of equipment that has its own inspection schedule. Fire hoses are not included, but do have testing procedures for that particular service. NOTE that good judgment should be exercised with the use of all hoses, and any obvious defects should be addressed. 

A visual inspection of the hose must be made before each use for loose or defective fittings, cracking, bulges, ruptures, and contamination in the hose that could result in a problem with the material intended to be moved through the hose. Defects are to be repaired or the hose disposed of to prevent inappropriate use later. 

Braided hoses are to be tested every six months due to the lower reliability. Braiding should also be visually inspected before each use. 

The atomic orbitak suitable for comlwation into hybrid orbitals in a given molecule or ion will he (hose that meet certain symmetry enteria. The relevant symmetry pn rties of orbitals can be extracted from character tables by simple inspection. We have already pointed out (page 60) that the p. orbital transforms in a particular point group in the same manner as an x vector. In other words, a Pj, oitntal can serve as a basis function for any irreducible representation that has V listed among its basis functions in a character table. Likewise, the p, and P orbitab transform as y and z vectors. The d orbitals—d, d dy., and d,—transform as the binary... 

If hoses are used to make sterile transfers, frequent inspection and replacements must be made. 

While it is important to take proper precautions (see Appendix 2), properly built equipment offers few hazards if relatively small quantities of liquids are used under pressure. The energy stored in a compressed liquid is of the order of 0.2-0.5 kJ mor kbar" this is much less than in a gas. In the event of the catastrophic failure of a vessel, only around 10 per cent of the liquid would need to escape to reduce the pressure to the atmospheric value, and double-walled vessels are unlikely to suffer a failure of both cylinders. The author has experienced the failure of a piston-cylinder apparatus which led to nothing more than a sudden depressurization. On the other hand, hazards may arise from the low-pressure side, which is likely to be carrying oil at 500 bar or more a pin-hole jet at this pressure can penetrate the human body. The valve threads may become worn and the stems may then be forcibly ejected. So hose connections should be inspected and renewed regularly and, where possible, they should be shielded from personnel, the valves should be mounted with the stems pointing away from the operator, and the guidelines set out in the code of practice (see Appendix 2) should be followed.
