THE security industry will face tighter licensing controls in 1995 when a series of stringent regulations come into force. The Government plans to introduce a two-tier licensing system under the Security and Guarding Services Bill which will require security companies to apply for licences and security guards to apply for permits. Detailed licensing criteria will be set by a security and guarding services authority, still to be established. A Security Branch spokesman said the aim of the bill was ''to promote higher standards of security and guarding services''. ''The administration has simply recognised a need for a comprehensive system of regulations,'' the spokesman said. ''Currently, there are insufficient provisions to regulate the industry and because the industry is growing, the Government wants to ensure the public is guaranteed a reliable and reasonable service.'' The Government estimated that the legislation would affect more than 100,000 watchmen and more than 200 security companies. The bill was gazetted yesterday after six years of consultation between the Advisory Committee on Regulating the Security Industry - which is a sub-committee of the Fight Crime Committee - and members of the industry. There will be a 12-month grace period for security companies to comply with licensing requirements after they are passed by Legco. The legislation is likely to be implemented in mid-1995. The Security Branch spokesman said the complexity of the industry warranted the length of time it took to gazette the new laws but added that the legislation was not inspired by serious government concerns about poor-quality security services. Under the Security and Guarding Services Bill it will be an offence for: A person to engage in security work without a valid permit. A company to supply security personnel who do not have valid permits. A person to require another who does not have a valid permit to do security work. A person to employ an individual to do security work without informing the Police Commissioner within 14 days of the start of employment. Security Systems managing director, Stewart Park, said the industry would support the bill because its purpose was to increase control of security companies and to ensure a set standard. ''And by raising the level of quality, the bill will discourage second-rate operators from offering security services. ''It should also prevent 'Mickey Mouse' alarm systems from being installed which will save police time they may have wasted answering false alarms,'' Mr Park said. He said the regulations might also discourage a number of smaller companies from operating. ''Basically, it will ensure quality based criteria are met which will lead to the public receiving a much improved security service,'' he said.
