5.1.2 use, adjustment and maintenance Bending should be identified in the use, adjustment and maintenance work predictability hazards, such as.

--- Raw materials and work roll bite between points;

--- Mold mounting/replacement;

--- Programming errors or failing to change Bending original function or performance;

--- Clean coiling machine;

--- In automatic operation function usage job site observation;

--- On the rolling machine to detect the workpiece;

--- Remove the workpiece from the rolling machine;

--- Not firmly angle bolt stress test under the conditions.

5.1.3 Run Predictability should recognize the danger associated with coiling during operation. These hazards include.

--- Non-normal operation; coiling as overload, failure to use the procedures specified in the instructions rolling machine;

--- Normal operation; bite-point between the plate and the work roll, staff error information exchange, thermal radiation (warm or hot roll volumes);

--- System errors and abnormal conditions; control system information loss/interference, non-normal information transfer;

5.1.9 Other

--- Coiling around the work environment;

5.2 hazard control

5.2.1 eliminate dangerous Bending should be consistent with the principle of inherently safe design, the design by eliminating the danger. Intrinsically safe design should be consistent with GB/T 15706.1, GB/T 15706.2 requirements.

5.2.2 Security guards Can not be designed to eliminate the danger, it should be through the use of security guards to control hazards, and shall comply with the provisions of Chapter 8.

5.2.3 safe work practices Not suitable for safety guards to prevent danger, should develop safe work practices to prevent danger generation.

5.2.4 Warning
