Back 14

Ingestion requires vomiting to be induced and

If the victim is unconscious artificial respiration should be applied (not mouth to mouth).

Skin contact should be washed off with cold water. Clothes should be removed from the victim and disposed of via the OTTO fuel HAZMAT clean up routines and bins provided.

Seek immediate medical advice.

Back 29

8. In situations where not all of the required keys or machinery tallies can be returned however the OOD feels that the initiator can safely conduct the desired task, possibly with emitter restrictions (reduced power, sector blanking etc), the RRO is to be approached to approve a HAZARD departure. If the RRO or his formally delegated representative is not available, no departure is to be granted.

Front 31

Danger Due to Arcing Replacement of Fuses

1. If a fuse is removed from a high voltage circuit which is supplying a load, arcing can occur which may cause ionisation of the surrounding air creating a self sustaining arc and resulting in a short circuit, fire and possible personal injury. The following precautions are therefore always to be observed on 440V AC circuits.

Back 31

a. Never remove a fuse unless the load circuit is switched OFF.

b. Never replace fuses in a circuit with the load switched ON.

c. When removing or replacing fuses do not look directly at the fuse in case of arcing.

d. Fuse carriers should be replaced smartly and tightened to assure a sound contact.

e. Always check that a fuse of the correct capacity is fitted.
