Question

when are you issued a tdg certificate?
once you have passed a written and practical test
once your employer determines you are adequately trained
once you have completed 10 hours of hands - on training

Explanation:

TDG (Transportation of Dangerous Goods) certification is typically issued when an employer determines that an individual is adequately trained. This is because the employer has the responsibility to ensure that employees handling dangerous goods have the necessary knowledge and skills, which may not be solely determined by a written and practical test (as the employer's assessment of overall training adequacy is key) and 10 hours of hands - on training is too arbitrary a measure compared to the employer's comprehensive determination.

Answer:

Once your employer determines you are adequately trained
