tray at least a foot deep, and such receptacles shall be moved
at least 500 ft. distant from any place where work is being
carried on.

108. (1) No person shall commence repairs in an oil-tank or
     adjacent thereto, in a dock or on a slipway, which is required as
     hereinafter provided to have a certificate of test, until such
     certificate or a copy thereof has been delivered to the proprietor
     of such dock or slipway.

(2) Until the said certificate of test has been delivered as
aforesaid no person shall bring near, or take into, any oil-tank
any naked light, fire, or lamp other than a properly enclosed
electric lamp, or apparatus of any kind for producing a light or
spark, nor shall he enter any such tank, except for the purpose
of testing the atmosphere or undertaking the necessary cleaning.

(3) If the cargo last contained in the oil-tank was oil with
a flash-point below 73 degrees Fahrenheit (close test) a fresh
certificate of test shall be obtained daily before work is com-
menced therein; and if during the course of such work any
pipe or joint in the oil-tank is broken or any other risk of oil
or oil-vapour entering it arises, work therein shall be suspended
until a further certificate of test has been obtained.

(4) No naked lights, fires, or lamps other than properly
enclosed electric lamps and no apparatus of any kind which
might produce a light or spark shall be permitted in any part of
a ship or barge which has been carrying oil as cargo until a
certificate of test has been obtained in respect of that part:
Provided that until any oil-tank has been opened, this clause
shall not apply to any part of a ship or barge where naked lights
were allowed when the ship or barge was at sea.

(5) Every certificate of test shall be posted as soon as may be
in a conspicuous place where it can be easily read by all persons
concerned.

(6) The proprietor of a dock or slipway may at any time
prior to the commencement of such work demand from the
master of the ship a certificate giving the flash-point of the fuel
oil which is, or has been immediately prior to such commence-
ment, in any tank or space on the ship; and the master shall
forthwith supply such certificate.

(7) Clauses (2) and (4) of this regulation shall not apply to

quently been used for carrying oil.

vapour, and found the space or spaces to be free
therefrom.

(9) The provisions of paragraphs (1), (2), (4), (5), and (6) of
this regulation shall apply to tanks which have contained fuel-oil,
except that the certificate of test required shall be a certificate
given by the person responsible for the execution of any work
in the tank that he has carried out an adequate and suitable
test, with an apparatus approved by a competent authority as
accurate and reliable for determining the presence of any
inflammable vapour, and has found the tank free therefrom.

109. Before any oil-tank is tested—
     (a) All residual oil and any sludge or deposit therein shall be
     removed from any such tank which has contained petrol
     or petroleum, and where any person is employed in
     the cleaning of a tank which has contained oil with a
     flash-point below 73 degrees Fahrenheit (close test)
