Protective glasses, protective gloves (PVC/Rubber/Butyl rubber/Neoprene/Nitrile/ clothing to minimise exposure.
If workplace exposure limit(s) of product or any component is exceeded (see exposure guidelines), a NIOSH/MSHA approved air supplied respirator is advised in absence of proper environmental control. OSHA regulations also permit other NIOSH/MSHA respirators (negative pressure type) under specified conditions see your industrial hygienist). Engineering or administrative controls should be implemented to reduce exposure.
Avoid dust formation. Sources of ignition should be kept clear. Clean-up personnel should wear suitable clothing with protective goggles, gloves and approved dust mask. Do not flush away spills or spill area residues. Sweep oe shovel up spills together with dust binding agent or use a vacuum cleaner. Place waste in labelled drums for disposal.

Contact a physician, medical facility, or poison control center for advice about whether to induce vomiting. If possible, do not leave individual unattended.
Move patient to fresh air. Monitor for respiratory distress. If cough or difficulty breathing develops, evaluate for respiratory tract irritation, bronchitis, or pneumonitis. Administer oxygen and assist ventilation as required. Treat bronchospasm with beta2 agonist and corticosteroid aerosols.
Remove contaminated clothing and wash exposed area thoroughly with soap and water. A physician should examine the area if irritation or pain persists.
Irrigate exposed eyes with copious amounts of tepid water for at least 15 minutes. If irritation, pain, swelling, lacrimation, or photophobia persist, the patient should be seen in a health care facility.
