2-ethyl-3-hydroxy-4-pyrone

Guidance on Safe Use

First-aid measures

- General advice:

Call a poison center or a doctor if you feel unwell.

- Following inhalation:

Remove person to fresh air and keep comfortable for breathing. Obtain medical advice.

- Following skin contact:

Remove contaminated clothes. Wash thoroughly with water (and soap). Contact physician if symptoms persist.

- Following eye contact:

Flush immediately with water for at least 15 minutes. Contact physician if symptoms persist.

- Following ingestion:

Rinse mouth. Call a poison center or a doctor if you feel unwell.

- Most important symptoms and effects:Harmful if swallowed.

Fire-fighting measures

- Suitable extinguishing media:

Dry powder. Foam. Carbon dioxide.

- Unsuitable extinguishing media:

Do not use a direct waterjet on burning material.

- Special hazards arising from the substance or mixture:

Fire hazard:Thermal decomposition may produce : Carbon oxides (CO, CO2).

Hazardous decomposition products in case of fire:Toxic fumes may be released.

- Advice for fire fighter:Do not attempt to take action without suitable protective equipment. Self-contained breathing apparatus. Complete protective clothing.

Accidental release measures

- Personal precautions, Protective equipment and emergency procedures:

Ventilate spillage area.

Avoid inhalation and contact with skin and eyes. A self-contained breathing apparatus is recommended in case of a major spill.

Do not attempt to take action without suitable protective equipment. For further information refer to section 8: "Exposure controls/personal protection".

- Environmental precautions:

Avoid release to the environment. Keep away from drains, surface- and groundwater and soil.

- Methods and material for containment and cleaning up:Clean up spillage promptly. Remove ignition sources. Provide adequate ventilation. Avoid excessive inhalation of vapours. Gross spillages should be contained by use of sand or inert powder and disposed of according to the local regulations;Dispose of materials or solid residues at an authorized site.

Handling and storage

- Precautions for safe handling:

Avoid excessive inhalation of concentrated vapors. Follow good manufacturing practices for housekeeping and personal hygiene. Wash any exposed skin immediately after any chemical contact, before breaks and meals, and at the end of each work period. Contaminated clothing and shoes should be thoroughly cleaned before re-use.

If appropriate, procedures used during the handling of this material should also be used when cleaning equipment or removing residual chemicals from tanks or other containers, especially when steam or hot water is used, as this may increase vapor concentrations in the workplace air. Where chemicals are openly handled, access should be restricted to properly trained employees.

Keep all heated processes at the lowest necessary temperature in order to minimize emissions of volatile chemicals into the air.

Advice on protection against fire and explosion : Keep away from ignition sources and naked flame.

- Hygiene measures: Do not eat, drink or smoke when using this product. Always wash hands after handling the product.

- Conditions for safe storage, including any incompatibilities:Store in a cool, dry, ventilated area away from heat sources. Keep containers upright and tightly closed when not in use .

Exposure controls / personal protection

1. Organisational protection measures:Ensure good ventilation of the work station. Where appropriate, use closed systems to transfer and process this material.

If appropriate, isolate mixing rooms and other areas where this material is used or openly handled. Maintain these areas under negative air pressure relative to the rest of the plant.

2. Hand protection:Avoid skin contact. Use chemically resistant gloves.

3. skin and Body protection:Wear suitable protective clothing

4. Eye protection:Use tight-fitting goggles, face shield or safety glasses with side shields if eye contact might occur.

5. Respiratory protection:Use local exhaust ventilation around open tanks and other open sources of potential exposures in order to avoid excessive inhalation, including places where this material is openly weighed or measured. In addition, use general dilution ventilation of the work area to eliminate or reduce possible worker exposures. No respiratory protection is required during normal operations in a workplace where engineering controls such as adequate ventilation, etc. are sufficient.

6. Hygiene measures:To the extent deemed appropriate, use an experienced air sampling expert to identify and measure volatile chemicals that could be present in the workplace air to determine potential exposures and to ensure the continuing effectiveness of engineering controls and operational practices to minimize exposure.

If engineering controls and safe work practices are not sufficient, an approved, properly fitted respirator with organic vapor cartridges or canisters and particulate filters should be used:

a) while engineering controls and appropriate safe work practices and/or procedures are being implemented; or

b) during short term maintenance procedures when engineering controls are not in normal operation or are not sufficient; or

c) if normal operational workplace vapor concentration in the air is increased due to heat ;

d) during emergencies; or

e) if engineering controls and operational practices are not sufficient to reduce airborne concentrations below an established occupational

exposure limit.

Stability and reactivity
