Parker Safety Guide ! Parker Safety Guide for Selecting and Using Hose, Tubing, Fittings, and Related Accessories Parker Publication No. 4400-B.1 Revised: May 2002 WARNING: Failure or improper selection or improper use of hose, tubing, fittings, assemblies or related accessories ("Products") can cause death, personal injury and property damage. Possible consequences of failure or improper selection or improper use of these Products include but are not limited to: � Fittings thrown off at high speed. � High velocity fluid discharge. � Contact with conveyed fluids that may be hot, cold, toxic or oth- erwise injurious. � Explosion or burning of the conveyed fluid. � Sparking or explosion caused by static electricity buildup or � Electrocution from high voltage electric power lines. other sources of electricity. � Contact with suddenly moving or falling objects that are con- � Sparking or explosion while spraying paint or flammable liquids. trolled by the conveyed fluid. � Injuries resulting from inhalation, ingestion or exposure to flu- � Injections by high-pressure fluid discharge. ids. � Dangerously whipping Hose. Before selecting or using any of these Products, it is important that you read and follow the instructions below.
