§ Mr. DobsonTo ask the Secretary of State for the Home Department, pursuant to his answer to the hon. Member for Holborn and St. Pancras of 3 December, whether the practical tests on the Heathrow underground loop referred to involved staff wearing breathing equipment; and whether the tests included simulated smoke and other hazards.
§ Mr. Douglas HoggThe London fire brigade has informed us that two firefighters paced the distance wearing breathing apparatus in darkness using hand-held torches. Simulated smoke was not used, but account was taken in the test of its likely effect on progress.
