Canon PowerShot A430 Advanced User's Manual page 11

Do not trigger the flash in close proximity to human or
animal eyes. Exposure to the intense light produced by the
flash may damage eyesight.
In particular, remain at least one meter (39 inches) away from
infants when using the flash.
Keep objects that are sensitive to magnetic fields (such as
credit cards) away from the speaker of the camera
(PowerShot A430 only).
Such items may lose data or stop working.
