First aid

General first aid measures. Get medical advice if you feel unwell

If inhaled

IMMEDIATELY leave the contaminated area, take deep breaths of fresh air. If symptoms (such as wheezing, coughing, shortness of breath, or burning in the mouth, throat, or chest) develop, call a physician and be prepared to transport the victim to a hospital. Provide proper respiratory protection to rescuers entering an unknown atmosphere. Whenever possible, Self-Contained Breathing Apparatus (SCBA) should be used, if not available, use a level of protection greater than or equal to that advised under Protective Clothing.

Skin contact

IMMEDIATELY flood affected skin with water while removing and isolating all contaminated clothing. Gently wash all affected skin areas thoroughly with soap and water. IMMEDIATELY call a hospital or poison control center even if no symptoms (such as redness or irritation) develop. IMMEDIATELY transport the victim to a hospital for treatment after washing the affected areas.

Eye contact

First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.

If swallowed

DO NOT INDUCE VOMITING. Corrosive chemicals will destroy the membranes of the mouth, throat, and esophagus and, in addition, have a high risk of being aspirated into the victim's lungs during vomiting which increases the medical problems. If the victim is conscious and not convulsing, give 1 or 2 glasses of water to dilute the chemical and IMMEDIATELY call a hospital or poison control center. IMMEDIATELY transport the victim to a hospital. If the victim is convulsing or unconscious, do not give anything by mouth, ensure that the victim's airway is open and lay the victim on his/her side with the head lower than the body. DO NOT INDUCE VOMITING. Transport the victim IMMEDIATELY to a hospital.

Handling, storage and disposal

Summaries only, follow the supplier SDS for your grade

Safe handling

Fire: NO open flames, NO sparks and NO smoking. Above 44 °C use a closed system, ventilation and explosion-proof electrical equipment. Prevent build-up of electrostatic charges (e.g., by grounding).

Inhalation: Use ventilation, local exhaust or breathing protection.

Skin: Protective gloves. Protective clothing.

Eyes: Wear safety goggles or eye protection in combination with breathing protection.

Ingestion: Do not eat, drink, or smoke during work.

Storage

Fireproof. Separated from strong oxidants.

Disposal

Generators of waste (equal to or greater than 100 kg/mo) containing this contaminant, EPA hazardous waste number U057, F003, must conform with USEPA regulations in storage,transportation, treatment and disposal of waste. Cyclohexanone is a waste chemical stream constituent which may be subjected to ultimate disposal by controlled incineration.
