WARNING!
 
Risk of explosion caused by grinding dust or carbon fibres!
Enriched sanding/grinding dust can lead to dust explosions in the presence of ignition sources.
Sanding /grinding dust can be electrostatically charged when evacuated with extraction systems and poses an ignition hazard.
Always wear fine dust filter masks, safety glasses and protective gloves when handling carbon reinforced plastic materials.
The extraction systems must be grounded to prevent a dust explosion.
Avoid stirring up dust, immediately extract all dust caused by sanding/grinding with approved vacuum cleaners when processing carbon reinforced plastic materials.
Use only tools that have connections for extractor units.
Wipe away remaining dust residues with a moist, lint-free rag.
 

WARNING!
 
Risk of explosion and injury when handling polyester and epoxy resins!
When processing polyester and epoxy resins with their hardeners, vapours result which are generally combustible.
The vapours from liquid polyester and epoxy resins with hardeners and their mixtures are a health hazard. Direct contact with skin or eyes result in irritation.
No smoking!
No open flames!
Always use skin protection cream, protective gloves and safety glasses.
Provide for good ventilation at workplace.
Do not eat or drink at workplace.
Keep storage containers closed wherever possible or close immediately after use.
 

WARNING!
 
Risk of explosion caused by handling organic peroxide hardeners!
When processing organic peroxide hardeners, vapours are produced and can explode when ignited.
Keep storage containers wherever possible or close immediatley after use.
No smoking!
No open flames!
Provide for good ventilation at workplace.
Always use skin protection cream, protective gloves and safety glasses.
 

WARNING!
 
Sharp vehicle parts.
Caused by scraping or cutting.
Always wear protective gloves when working on or near sharp and burred vehicle parts.
Repair panels must be deburred.
 

WARNING!
 
Inhaling, or skin and eye contact with carbon fibres.
This dust or fibres irritate the bronchial tubes and may cause damage to the lungs.
Fibres that get stuck in the lungs can cause damage to the lungs.
Wear respiratory protection, protective gloves and safety glasses.
 

WARNING!
 
Contact with polyester and epoxy resins.
The vapours from liquid polyester and epoxy resins with hardeners and their mixtures are a health hazard.
Direct contact with skin or eyes result in irritation.
Always use skin protection cream.
Wear protective gloves and safety glasses.
Ensure that the area is well ventilated.
 

WARNING!
 
Contact with organic peroxide hardeners.
Direct contact with skin or eyes result in irritation.
Always use skin protection cream.
Wear protective gloves and safety glasses.
