Under the Transport of Dangerous Goods (Safety Advisers) Regulations 1999, a Dangerous Goods Safety Adviser (DGSA) must ensure that an annual report to the employer is prepared on the activities of the employer regarding the transport of dangerous goods. As DGSA's were legally required for businesses transporting dangerous goods (above certain thresholds) from 01 January 2000, the first annual report needs to cover the year 1 January 2000 - 31 December 2000. The employer must keep this report for a minimum period of 5 years.
