Seek medical attention immediately. Skin Contact Flush area with warm, running water for several minutes. Seek medical attention if irritation occurs. Inhalation Obtain fresh air. Seek medical attention immediately. Ingestion If conscious only: Rinse mouth with water. Do not induce vomiting. Contact a Poison Control Center or physician for instructions. Other Recommendations Wash clothing after reuse. 4.2 MOST IMPORTANT ACUTE AND CHRONIC EXPOSURE SYMPTOMS ACUTE: The following sections describe acute symptoms by route of exposure. o Inhalation - Over-exposure to mists or sprays of this product by inhalation may cause irritation of the nose, throat and respiratory tract. Inhalation over-exposures to this product can also be harmful. o Skin and Eyes – Based on pH levels, this product can cause skin irritation and serious eye irritation. Additionally, due to the presence of cyanide compounds, skin or eye contact can be harmful. o Ingestion - Though not anticipated to be a significant route of occupational exposure, ingestion of this product, even in small quantities, can be harmful. o All Routes of Exposure - Symptoms of cyanide exposure include sleepiness, dizziness, confusion, headache, nausea and vomiting. CHRONIC: Based on pH, chronic over-exposures to this solution can cause dermatitis (inflammation of the skin) after prolonged or repeated skin contact. TARGET ORGANS: Skin, eyes, respiratory system, blood and metabolic enzymes. 4.3 INDICATION OF IMMEDIATE MEDICAL ATTENTION AND SPECIAL TREATMENT NEEDED RECOMMENDATIONS TO PHYSICIANS: Treat symptoms and eliminate exposure. CYANIDE EXPOSURE PREPAREDNESS: All persons working with this product should be aware of the potential for cyanide sickness and trained to provide First-Aid using oxygen and amyl nitrite. Always have on-hand the materials needed. Actions to be taken in case of cyanide sickness should be planned and practiced before beginning work with cyanides. Identification of community hospital resources and emergency medical assistance in order that they be equipped and trained on the handling of cyanide emergencies is essential. ANTIDOTE: If the victim has difficulty breathing, is becoming confused and/or is losing consciousness, administer amyl nitrite. The following procedure is recommended: o Crush one pearl of amyl nitrite onto a cloth and hold to the victim’s nose for 15 seconds, then take away for 15 seconds. Repeat 5-6 times, using a new pearl every 5 minutes (0.3 mg size) or every 3 minutes (0.18 mg size), until patient regains consciousness. o While amyl nitrite is being used, monitor the victim’s blood pressure. If it drops below 80/60, stop the amyl nitrite and obtain the opinion of physician immediately. o If breathing has stopped, trained personnel should begin artificial respiration or, if the heart has stopped, begin cardiopulmonary resuscitation (CPR) immediately (avoid mouth to mouth contact). If breathing is difficult, oxygen (preferably 100 percent) may be helpful. o Quickly transport victim to an emergency facility. o Physicians should refer to Section 11 (Toxicology Information) for additional information. MEDICAL CONDITIONS AGGRAVATED BY OVEREXPOSURE: Over-exposure to this product may aggravate pre-existing respiratory, blood, and skin conditions.
