An operator suffered amputation of part of his thumb when the paper-cutting guillotine he was using overran. He was retrieving a cut stack and was injured when the blade failed to halt on the upstroke and descended part way. This was caused by a failure to maintain the brake, and a fault which occurred on the overrun detection switch. The solenoid-operated safety bolt for the knife carrier was also defective. The brake defect, overrun switch fault, and safety bolt were all rectified when the machine was subsequently serviced.

A paper-cutting guillotine operator suffered a crushed finger when it was trapped between the clamp and table. The operator was gauging and placed a block of paper on the table. The backgauge was too far back, he leaned forward to pull work out, intending to adjust the backgauge, and accidentally depressed the foot pedal, operating the clamp. The gauging force was excessive and as a result the operator was off work for four weeks.

Types of safeguard

Front guard29Because in the majority of circumstances operators have to place their hands beneath the knife when positioning the work, a combination of a high-integrity method of safeguarding and a two-hand control device is needed. The various options are described in paragraphs 30-47.

Appendix 6 Extract from the Health and Safety publication Electro-sensitive safety devices for friction-clutch press brakes eighth report of the joint standing committtee on safety in the use of power pressesThe following extract describes a full-function monitoring system applied to a press brake. The equipment used on a guillotine will differ, but the general principle of overrun protection is the same. Full-function monitoring is applicable only to guillotines manufactured and in use before 1985 - see paragraph 129.
