Wet Cleaning Wetting parts or jobs before starting work helps to keep fibres and dust from becoming airborne. A common practice is spraying parts or jobs with water and a wetting agent such as detergent. Hand or pump sprays are widely used to clean parts or whole jobs. This method is only effective if a fine mist is used. A fine mist wets the fibres and dust so that they cannot become airborne.
Large droplets can cause fibres and dust to be thrown into the air.
Collect any run-off in a tray or container placed under the job. Disposal of this waste must be in a manner that avoids future contamination once it dries out. Well designed and maintained ventilation systems in the workplace help lower the risk of breathing in harmful dust and fibres. These systems are important in workplaces which remove, re-line and bond frictional surfaces to vehicle parts. Machines such as sanders and grinders used in the brake bonding process should be fitted with properly designed and filtered extraction systems to remove and trap any dust that is created.
