Licensed Asbestos Supervisor Refresher Training

Course Prerequisites

The aim of refresher training is to identify good and bad practice and to ensure that the good practice is shared and that bad practices are stopped. Training Needs Analysis will help to make the annual courses more relevant to delegates. Refresher training should aim to achieve the following objectives:

• fulfil identified training needs;
• impart new information, eg changes in legislation and work practices (such as use of new equipment or wetting techniques);
• remind employees of the risks they face working with asbestos;
• reinforce procedures such as the use of hygiene facilities, use and maintenance of RPE and how to use controlled removal techniques;
• share good practice and eliminate bad practice.
