Advice for firefighters
Special protective equipment for fire-fighters:
- Wear an approved positive pressure self-contained breathing apparatus in addition to standard fire fighting gear.
Further information:
- Flammable liquid and vapour.
- Material will float and may ignite on surface of water.
- Use a water spray to cool fully closed containers.
Accidental release measures
Personal precautions, protective equipment and emergency procedures
Personal precautions:
- Wear appropriate personal protective equipment.
- Local authorities should be advised if significant spillages cannot be contained.
Environmental precautions
Environmental precautions:
- Avoid release to the environment.
Methods and material for containment and cleaning up
Methods for cleaning up:
- Contain spillage, soak up with non-combustible absorbent material, (e.g. sand, earth, diatomaceous earth, vermiculite)
and transfer to a container for disposal according to local / national regulations (see section 13).
- Eliminate all ignition sources if safe to do so.
- Prevent runoff from entering drains, sewers, or streams.
- After cleaning, flush away traces with water.
- Eliminate all ignition sources if safe to do so.
Handling and storage
Precautions for safe handling
Advice on safe handling:
- Keep away from heat, hot surfaces, sparks, open flames and other ignition sources. No smoking.
- Ground and bond container and receiving equipment.
- Use explosion-proof electrical equipment.
- Use non-sparking tools.
- Take precautionary measures against static discharges.
- Do not breathe vapors or spray mist.
- Use only with adequate ventilation.
- Avoid prolonged or repeated contact with skin.
- Wash thoroughly after handling.
- Minimize exposure to air.
- After opening, purge container with nitrogen before reclosing.
- Periodically test for peroxide formation on long-term storage.
Advice on protection against fire and explosion:
- None known.
Hygiene measures:
- Handle in accordance with good industrial hygiene and safety practice.
Conditions for safe storage, including any incompatibilities
Requirements for storage areas and containers:
- Keep container tightly closed and in a well-ventilated place.
- Keep away from heat and sources of ignition. Protect against light.

Exposure controls / personal protection
Country specific exposure limits have not been established or are not applicable unless listed below.
METHYL ISOAMYL KETONE
TLV-STEL: Threshold Limit Value-Short-Term Exposure Limit: 100 ppm / 475 mg/m³ (Basis: GB EH40)
Further information: Can be absorbed through the skin. The assigned substances are those for which there are concerns that dermal absorption will lead to systemic toxicity.
Time Weighted Average (TWA): 20 ppm / 95 mg/m³ (Basis: 2000/39/EC)
Further information: Indicative
Exposure controls
Engineering measures
Good general ventilation (typically 10 air changes per hour) should be used. Ventilation rates should be matched to conditions. If applicable, use process enclosures, local exhaust ventilation, or other engineering controls to maintain airborne levels below recommended exposure limits. If exposure limits have not been established, maintain airborne levels to an acceptable level.
Personal protective equipment
Eye protection :
- Wear safety glasses with side shields (or goggles).
Hand protection
Remarks:
- Wear suitable gloves.
Respiratory protection:
- If engineering controls do not maintain airborne concentrations below recommended exposure limits (where applicable)
or to an acceptable level (in countries where exposure limits have not been established), an approved respirator must be
worn.
Protective measures:
- Ensure that eye flushing systems and safety showers are located close to the working place.
- Remove respiratory and skin/eye protection only after vapors have been cleared from the area.
- Ensure that eye flushing systems and safety showers are located close to the working place.
- Use personal protective equipment as required.
