Laboratory Safety

It is important that everything you do in laboratories is done safely. If you

are unsure about any safety matter, ask the appropriate laboratory

supervisor for instruction.

Except when otherwise directed by the lecturer in charge, no experimental

circuit is to be made live until the lecturer, or one of the demonstrators, has

checked the circuit and ensured that all earth connections have been made.

If any faults with equipment are suspected, the laboratory supervisor

should be notified immediately.

No live experimental circuit is to be left unattended.

No student is to do any practical work using live equipment, or power and

machine tools, whilst alone in a laboratory or workshop.

It is highly desirable that shoes with insulating and non-slip soles and heels

are worn. Bare feet, jandals or loose sandals, will not be permitted in

laboratories.

Smoking, eating or drinking in the laboratories is forbidden.

After completion of an experiment students must tidy up and stow away.

Machines and Power Electronics Laboratories

When taking part in experiments on rotating machines, ensure loose

clothing or long hair that might entangle with equipment are restrained.

The main switchboard is not to be operated by students, except under the

direct supervision of a staff member.

Be aware of the location of the emergency “stop” and “trip” buttons.

After wiring the bench equipment, the supervisor must check the circuit

before the supply is switched on.

No leads are to be removed until the supply has been disconnected and any

associated machinery has stopped rotating.

Beware of energy storage devices, e.g. capacitors.

All equipments have a label affixed. Anyone found removing or tampering

the labels will be reported to the lecturer and head of department.
