First Aid Measures

Ingestion
If swallowed, wash out mouth with water provided person is conscious. Call a physician.
Inhalation
If inhaled, remove to fresh air. If not breathing give artificial respiration. If breathing is difficult, give oxygen.
Skin
In case of contact, immediately wash skin with soap and copious amounts of water. Remove contaminated clothing and shoes. Call a physician.
Eyes
In case of contact with eyes, flush with copious amounts of water for at least 15 minutes. Assure adequate flushing by separating the eyelids with fingers. Call a physician.

Exposure Controls/Personal Protection

Personal Protection
Compatible chemical-resistant gloves. Chemical safety goggles. Protective clothing.
Respirators
Use respirators and components tested and approved under appropriate government standards such as NIOSH (US) or CEN (EU). Where risk assessment shows air-purifying respirators are appropriate use a full-face particle respirator type N100 (US) or type P3 (EN 143) respirator cartridges as a backup to engineering controls. If the respirator is the sole means of protection, use a full-face supplied air respirator.
Exposure Effects
Some steroids show carcinogenic and teratogenic activity. Target organ: adrenal cortex.
