FEWER than half of heating and ventilating operatives are being asked to show CSCS cards to gain site entry.
A survey by the Heating and Ventilating Contractors Association showed that 43 per cent of site workers were asked to show their cards while 90 per cent of managers claimed to carry out the checks on subcontractors.
The HVCA has 40,000 holders of its CSCS-affiliated SKILLcard working in the industry but it is worried about the low rates of card-checking revealed in the survey.
The Major Contractors Group pledged that every worker on its sites should hold a CSCS card by 2004.
HVCA technical and safety manager Bob Towse said: 'We expect the MGG to do what it promised and restrict access to card holders only.'
