| Risk of accident
from vehicle starting off by itself when engine running. Risk of injury (bruises and burns) resulting from working on the engine while it is being started or when it is running. |
Secure vehicle to prevent it from starting off by itself. Wear closed and snug-fitting work clothes. Do not touch hot or rotating parts. | AS00.00-Z-0005-01A | |
| Risk of poisoning
from swallowing brake fluid. Risk of injury from skin and eye contact with brake fluid |
Only pour brake fluid into suitable and appropriately marked containers. Wear protective clothing and eye protection when handling brake fluid. | AS42.50-Z-0001-01A | |
