of Radiation Protection (Non-Ionising Radiation) Regulations
Regulation 22
Requirements for sunlamps
Subregulation 1
Every sunlamp shall be designed and constructed in such a manner that, under the conditions of use specified by the manufacturer —
the sunlamp functions in accordance with paragraphs (10), (11) and (12) for as long as the sunlamp has its original components or replacement components recommended by the manufacturer; and
no individual who uses the sunlamp will be exposed to ultraviolet radiation in excess of the exposure limits specified in Table 3 in the Third Schedule.
Subregulation 2
Every sunlamp shall be designed and constructed in such a manner that —
all marks, labels and signs in accordance with regulation 23 are permanently affixed to and clearly visible on the external surface when the sunlamp is assembled for use; and
all controls, meters, lights or other indicators are readily discernible and clearly labelled to indicate their function.
Subregulation 3
Every sunlamp shall be designed and constructed to include the following safety features:
a control by which the sunlamp may be easily turned off by the person being exposed at any time without disconnecting the electrical plug or removing the ultraviolet lamp or lamps; and
a timer that satisfies paragraph (11).
Subregulation 4
Every ultraviolet lamp intended for use in a sunlamp shall be designed and constructed in such a manner that it can only be inserted and operated in a sunlamp apparatus.
Subregulation 5
Every sunlamp shall be designed and constructed in such a manner that failure or malfunction of any component of the sunlamp does not result in the sunlamp not complying with paragraphs (10), (11) and (12).
Subregulation 6
Every sunlamp shall be accompanied by sufficient sets of protective eyewear that meet the requirements of paragraph (12) to at least equal the maximum number of persons who may, at the same time, be exposed to ultraviolet radiation from the sunlamp, as recommended by the manufacturer of the sunlamp.
Subregulation 7
Every ultraviolet lamp intended for use in a sunlamp or any packing uniquely associated with an ultraviolet lamp shall have a label that contains —
the words “DANGER — Ultraviolet radiation. Follow instructions. Use only in fixture equipped with a timer”; and
the model designation.
Subregulation 8
Paragraph (7) shall not apply to an ultraviolet lamp that is designed and manufactured for use in a sunlamp that is maintained and serviced by the same manufacturer.
Subregulation 9
Every sunlamp shall be equipped with —
instructions for the operation and safe use of the sunlamp that include a statement stating the maximum number of persons who may, at the same time, be exposed to ultraviolet radiation from the sunlamp, as recommended by the manufacturer of the sunlamp;
instructions for obtaining repairs and recommended replacement components and accessories that are compatible with the sunlamp, including protective eyewear, ultraviolet lamps, timers, reflectors and filters, in order that, if installed or used as directed the sunlamp continues to comply with the provisions of this Part; and
a warning that the instructions accompanying the sunlamp shall always be followed to avoid or minimise potential injury.
Subregulation 10
Every ultraviolet lamp intended for use in a sunlamp shall function in such a manner that, at any distance in any direction from the sunlamp, the irradiance within the wavelength range from 200 nm to not more than 260 nm does not exceed 0.3% of the irradiance within the wavelength range from 260 nm to not more than 320 nm.
Subregulation 11
The timer required by paragraph (3)(b) shall be designed so as to —
be adjustable to preset times and have maximum timer interval not exceeding the maximum exposure time;
have an error not greater than 10% of the maximum timer interval of the sunlamp;
not automatically reset and therefore cause radiation emission to resume when the sunlamp emissions have been terminated by the timer; and
not preclude a user of a sunlamp from resetting the timer before the end of the preset timer interval.
Subregulation 12
The protective eyewear required by paragraph (6) shall have a spectral transmittance not exceeding a value of 0.1% over the wavelength range from 200 nm to not more than 320 nm and a value of 1% over the wavelength range from 320 nm to not more than 400 nm and shall be sufficient over wavelengths greater than 400 nm to enable the user to see clearly enough to read the labels and reset the timer.
