Regulation 4 Hazardous equipment and materials
This regulation applies in relation to the use of—
any radioactive material which has a specific activity in excess of 100 becquerels per gram, or
any equipment in which electrons are accelerated by a potential difference of at least 5 kilovolts other than—
a television receiving set, or
equipment designed primarily to produce visual images derived from video recordings, closed circuit television equipment or the output of a computer.
The governing body of a further education institution shall prevent the use in the institution of such equipment or materials unless that use is for the time being approved by the Secretary of State.
The Secretary of State shall withdraw an approval if at any time he is of the opinion that arrangements made in relation to the equipment or materials to which the approval applies for the health and safety of persons at the institution are inadequate.
An approval for the purposes of this regulation may apply generally (subject to such exceptions, if any, as are specified therein) or only in a particular case.
