4. First-Aid Measures
If Inhaled If the high concentration of dust is inhaled or respiratory symptoms (coughs, gasping,shortness of breath, etc.) are experienced, move to fresh air and take a rest with postureeasy to breathe. If breathing difficulties occur, administer oxygen inhalation. If breathinghas stopped, immediately administer artificial respiration and get medical
advice/attention.
 If irritation or rash persists, get medical advice and attention.
If on Skin If dust is contacted with skin, take off contaminated clothing and rinse the affected areawith soapy water thoroughly. If irritation or rash persists, get medical advice/attention.
