First Aid Measures
Emergency procedures for chemical exposure incidents
Move to fresh air. Get medical attention if symptoms occur. If not breathing, give artificial respiration.
Symptoms: Breathing difficulties. Inhalation of high vapor concentrations may cause symptoms like headache, dizziness, tiredness, nausea and vomiting
Wash off immediately with plenty of water for at least 15 minutes. Get medical attention if symptoms occur.
Rinse immediately with plenty of water, also under the eyelids, for at least 15 minutes. Obtain medical attention.
Do not induce vomiting. Obtain medical attention.
Symptoms: Symptoms of overexposure may be headache, dizziness, tiredness, nausea and vomiting
Immediate Medical Attention
Obtain medical attention for eye contact and ingestion. Get medical attention if symptoms occur for skin and inhalation. If not breathing, give artificial respiration for inhalation.
Medical Treatment
Treat symptomatically
Firefighting Measures
Extinguishing media, specific hazards, and firefighter protection
CO 2, dry chemical, dry sand, alcohol-resistant foam. Cool closed containers exposed to fire with water spray.
Water may be ineffective
Flammable. Risk of ignition. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Containers may explode when heated. Thermal decomposition can lead to release of irritating gases and vapors. Keep product and empty container away from heat and sources of ignition.
Cool closed containers exposed to fire with water spray.
Firefighter Protection
As in any fire, wear self-contained breathing apparatus pressure-demand, MSHA/NIOSH (approved or equivalent) and full protective gear.
Accidental Release Measures
Spill cleanup procedures, containment, and environmental protection
Use personal protective equipment. Remove all sources of ignition. Take precautionary measures against static discharges. Avoid contact with skin, eyes and clothing. Ensure adequate ventilation.
Avoid release to the environment. See Section 12 for additional ecological information.
Soak up with inert absorbent material. Keep in suitable, closed containers for disposal. Use spark-proof tools and explosion-proof equipment.
Materials: inert absorbent material
Related Substances
Similar chemicals with comparable safety profiles
Handling and Storage
Safe handling precautions, storage conditions, and workplace requirements
Wear personal protective equipment. Avoid contact with skin, eyes and clothing. Avoid ingestion and inhalation.
Keep containers tightly closed in a dry, cool and well-ventilated place. Keep away from heat and sources of ignition.
Keep away from open flames, hot surfaces and sources of ignition. Take precautionary measures against static discharges. Use only non-sparking tools. To avoid ignition of vapors by static electricity discharge, all metal parts of the equipment must be grounded. Keep away from heat and sources of ignition.
Exposure Controls / PPE
Occupational exposure limits, engineering controls, and protective equipment
Ensure adequate ventilation, especially in confined areas. Use explosion-proof electrical/ventilating/lighting/equipment. Ensure that eyewash stations and safety showers are close to the workstation location.
Wear appropriate protective gloves
Wear appropriate protective eyeglasses or chemical safety goggles as described by OSHA's eye and face protection regulations in 29 CFR 1910.133 or European Standard EN166.
Follow the OSHA respirator regulations found in 29 CFR 1910.134 or European Standard EN 149. Use a NIOSH/MSHA or European Standard EN 149 approved respirator if exposure limits are exceeded or if irritation or other symptoms are experienced.
Wear appropriate protective clothing to prevent skin exposure.

Ecological Information
Environmental toxicity, biodegradation, and bioaccumulation data
Ecotoxicity
Methyl ethyl ketone shows acute toxicity to fish (Lepomis macrochirus LC50=3.22 g/L 96h, EC50=3403 mg/L 30min), water fleas (Daphnia magna EC50 ranging from 4025-6440 mg/L 48h, 5091 mg/L 48h, and >520 mg/L 48h), and bacteria (Microtox EC50=3403 mg/L 30min, 3426 mg/L 5min). No data is listed for freshwater algae.
Persistence and Degradability
Persistence is unlikely based on available information.
Bioaccumulation/ Accumulation
No specific bioaccumulation information is available, but the log Pow for Methyl ethyl ketone is 0.29, suggesting low bioaccumulative potential.
Mobility
The substance is likely to be mobile in the environment due to its volatility.
