Kulkoni, Inc. v921 WARNING: NEVER EXCEED WORKING LOAD LIMIT Page 86 DEFINITIONS Design (Safety) Factor: An industry term denoting a product's theoretical reserve capability; usually computed by divid- ing the catalog Ultimate Load by the Working Load Limit. Generally expressed for blocks as a ratio of 4 to 1. Proof Load: The average force applied in the performance of a proof test; the average force which a product may be subjected before deformation occurs. Proof Test: A test applied to a product solely to determine non-conforming material or manufacturing defects. Shock Load: A force that results from the rapid application of a force (such as impacting and/or jerking) or rapid move- ment of a static load. A shock load significantly adds to the static load. Snatch Block: An assembly consisting of a sheave(s), side plates, and generally an end fitting (hook, shackle, etc.) that is used for lifting, lowering, or applying tension. Static Load: The load resulting from a constantly applied force or load. Working Load: The maximum mass or force which the product is authorized to support in a particular service. Working Load Limit: The Working Load Limit is the maximum load which should ever be applied to a product, even when the product is new and when the load is uniformly applied - straight line pull only. Avoid side loading. All catalog ratings are based upon usual environmental conditions, and consideration must be given to unusual conditions such as extreme high or low temperatures, chemical solutions or vapors, prolonged immersion in salt water, etc. Such conditions or high-risk applications may necessitate reducing the Working Load Limit. This term is used interchangeably with the following terms: WLL, SWL, Safe Working Load, Rated Load Value, Resulting Safe Working Load, and Rated Capacity. Never exceed the Working Load Limit. Ultimate Load: The average load or force at which the product fails, or no longer supports the load. SNATCH BLOCKS - WARNINGS AND INFO. READ THE FOLLOWING WARNINGS AND SAFETY INFORMATION CAREFULLY. EVEN EXPERIENCED PERSONNEL NEED TO UNDERSTAND THIS INFORMATION. Failure to follow warnings and instructions can result in serious injury or death. To avoid serious injury, death, or property damage -  Always design and rig snatch block systems so that the load will not slip or fall.  Always design the lifting system with appropriate sheave assembly material to prevent premature sheave, bearing or wire rope wear and failure.  Always have a qualified person (as defined by ANSI/ASME B.30) rig the snatch block system.  Instruct workers to keep hands and body away from the block sheaves, swivels, and "pinch points" where wire rope makes contact with block parts or loads.  Do not side load snatch blocks - side loading exerts additional force or loading which the snatch block is not de- signed to accommodate.  Instruct workers to be alert and to wear appropriate safety gear in areas where loads are moved or supported with snatch block systems.  Always make sure the hook (and not the latch) supports the load.  Do not weld snatch blocks or load supporting parts.  Keep out from under a raised load and stay out of the line of force.  Never lift personnel with a hook snatch block.  Remove from service any snatch block that is cracked or deformed.  Always regularly inspect, lubricate, and maintain snatch blocks.
