Health Hazards Information - Recommended Personal Protective Equipment: Full rubber protective
clothing, inc. gloves and boots; chemical worker’s goggles; face shield where contact with face is
likely. If necessary to enter closed area for H hr or less with mist, wear full-faced gas mask with
canister approved by Bureau of Standards for use with ammonia; Symptoms Following Exposure: High
concentration of vapor burns eyes and irritates the nose and throat. Liquid burns eyes and skin; General
Treatment for Exposure: Get medical help immediately! INGESTION: drink large amounts of water
or milk quickly, induce vomiting only if instructed by physician. EYES: flush immediately and
thoroughly with flowing water for at least 15 min. SKIN: remove clothing and flush affected area with
copious amounts of water, then wash with soap and water; severe Exposure may require showering;
