New smoking legislation could result in substantial fines for the unprepared.

The smoking ban which comes into effect on 1 July affects virtually all enclosed workspaces, along with public places. Nearly all premises are affected, apart from those which have openings that amount to more than 50% of the overall wall space. This does not include doors or windows.

Work vehicles which transport more than a single person also have to be smoke free. Private vehicles, or those hired for private use, are not included in the ban.

Designated smoking rooms are also prohibited under the new legislation. Outdoor smoking areas, however, are not affected, as long as any shelters that are provided follow the 50% rule.

Employers are required to be pro-active in banishing smoking on their premises. No smoking signs, featuring the internationally recognised symbol, must be displayed at every public entrance. They must also contain the text: ‘No smoking. It is against the law to smoke on these premises.’ In addition, the dimensions of the entrance signs should be no less than 148 mm x 210 mm.

Failure to display no-smoking signs can lead to a fixed penalty notice of £200, imposed on whoever manages or occupies the premises or vehicle.

Failing to prevent smoking in a smokefree place could result in a maximum fine of £2500 for management, although there is no fixed penalty notice for this offence. Employees who disregard the ban may face a £50 fine.

A telephone line (0800 587 1667) is in operation to enable people to report breaches of the law in confidence.
