4 Hazards The accidental release of a load, or release of a load due to failure of a component puts at risk, either directly or indirectly, the safety or health of those persons within the danger zone. In order to provide the necessary strength and durability of lifting accessories this Part of EN 1492 specifies requirements for the design, manufacture and testing to ensure the specified levels of performance are met. Endurance has not been identified as a hazard when flat woven webbing slings having the specified levels of performance given in this Part of EN 1492 are used in general lifting service. Since failure can be caused by the incorrect choice of WLL and specification of lifting accessory this Part of EN 1492 also gives the requirements for marking and the manufacturer’s certificate. Aspects of safe use associated with good practice are given in annex B (normative) and annex D (informative). Table 1 lists those hazards in so far as they are dealt with in this standard that require action to reduce those risks identified by risk assessment as being specific and significant for flat woven webbing slings made of polyamide, polyester and polypropylene .
