Fly ashes and exhaust gas dust


Study the safety instructions before starting to overhaul the exhaust gas system, or engine components that have been in contact with exhaust gases.

Precautions for handling fly ashes and exhaust gas dust

When handling fly ashes, exhaust gas dust or any contaminated components, observe the following requirements and precautions:
Avoid inhaling and swallowing fly ashes and dusts. Prevent eye and skin contacts.
Avoid spreading and spilling the fly ashes and dusts to the environment.
Take measures to avoid spreading the dust in the surrounding area when opening the manholes of the exhaust gas system, especially the Selective Catalytic Reduction (SCR) system (if included). Avoid spreading dust when handling exhaust gas system components.
Take care that the ventilation is suitable when collecting dust arisen during the machining and cleaning of the components.
Apply appropriate disposal instructions for flue gas dust spillage. The dust collected from the exhaust gas system must be considered as hazardous waste. It must be treated according to the local regulations and legislation.

Personal protection equipment for fly ashes and exhaust gas dust

Respiratory organ protection: Use P3 filter respirator against toxic particles.
For work inside the SCR or other places in the exhaust gas system, where the dust concentration is high, a respiration mask with fresh filtered compressed air supply is recommended.
Hand protection: Use gloves.
Eye protection: Wear goggles.
Skin and body protection: Wear covering clothes.
Use proper protection also when machining or cleaning engine components that have been in contact with exhaust gases.

First aid measures for fly ash and exhaust gas accidents

Inhalation of ashes: Move the victim to fresh air.
Keep the victim warm and lying still.
Give oxygen or mouth to mouth resuscitation if needed.
Seek medical advice after a significant exposure.
Skin contact: If the ash is hot, cool the skin immediately with plenty of cold water.
Wash immediately with plenty of water and soap.
Do not use solvents as it disperses the
ash and may cause skin absorption.
Remove contaminated clothing.
Seek medical advice if irritation develops.
Eye contact: Rinse immediately with plenty of water for at least 15 minutes and seek medical advice.
If possible, keep rinsing until eye specialist has been reached.
Ingestion: Rinse the mouth with water.
