First-aid measures

INHALATION

If inhaled, move to fresh air. Rinse nose and mouth with water. Get medical attention if symptoms (repeated sneezing) develop.

SKIN CONTACT

Remove contaminated clothing. Wash exposed skin with soap and water for at least 15 minutes. Seek medical attention if symptoms develop.

EYE CONTACT

Rinse eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. If easy to do, remove contact lenses if worn, continue rinsing. Seek medical attention if symptoms develop.

INGESTION

If swallowed, wash out mouth with water. Seek medical attention if larger quantities have been ingested.

MOST IMPORTANT SYMPTOMS AND EFFECTS, BOTH ACUTE AND DELAYED

To the best of our knowledge the toxicity of this substance has not been fully investigated, thus symptoms and effects are not fully known. Irritation effects such as skin and eye irritation and to upper respiratory tract are expected. Other adverse effects cannot be excluded.

INDICATION OF ANY IMMEDIATE MEDICAL ATTENTION AND SPECIAL TREATMENT NEEDED

Treat symptomatically and supportively.

Fire-fighting measures

EXTINGUISHING MEDIA

- Suitable extinguishing media:

Use water spray, foam, dry powder or carbon dioxide as appropriate for surrounding fire and materials.

- Unsuitable extinguishing media:

No limitations given for this substance.

SPECIAL HAZARDS ARISING FROM THE SUBSTANCE OR MIXTURE

Combustible, but not flammable. In case of fire toxic fumes of carbon monoxide (CO) and hydrogen chloride (HCl) may be formed.

No explosivity or flammability data identified. High concentrations of finely divided airborne organic particles can potentially explode if ignited.

ADVICE FOR FIREFIGHTERS

Wear self-contained breathing apparatus and protective clothing to prevent contact with skin and eyes. Prevent fire-extinguishing water from contaminating the watercourses.

Accidental release measures

PERSONAL PRECAUTIONS, PROTECTIVE EQUIPMENT AND EMERGENCY PROCEDURES

If product is released or spilled, take proper precautions to minimize exposure by using appropriate personal protective equipment (see Section Exposure controls / personal protection). Avoid raising dust. Area should be adequately ventilated.

ENVIRONMENTAL PRECAUTIONS

Collect spillage and place in specific bins and send for destruction. Avoid release to drains. End with flushing the spillage area with water.

METHODS AND MATERIAL FOR CONTAINMENT AND CLEANING UP

A small spill may be handled with water moistened disposable cloth and placed in container for chemical waste. A larger spill should be collected and placed in container for disposal. Use recommended personal protective equipment. Wash spill site with water after completed pick up.

Handling and storage

PRECAUTIONS FOR SAFE HANDLING

Avoid dust generation and inhalation of dust. Avoid contact with eyes and skin. Ensure good ventilation. The material may form flammable dust clouds in air. Dust clouds may be extremely sensitive to ignition by electrostatic discharge and other ignition sources. Ensure good earthing of equipment and personnel.

CONDITONS FOR SAFE STORAGE, INCLUDING ANY INCOMPATIBILITIES

Store at ambient conditions, generally 15 to 25C, and keep the container tightly closed.

Exposure controls / personal protection

CONTROL PARAMETERS

To the best of our knowledge, established occupational exposure limit value is not available.

Recommended Occupational Exposure Limit Value:

Substance                               Value                    Control Parameters           Comments

4-(Chloroacetyl)catechol        100 µg/m3               LTEL 8h                               In-house limit

LTEL: Long-term exposure limit (8h TWA / time-weighted average)

EXPOSURE CONTROL

Appropriate engineering controls

Use appropriate controls (eg. containment, local exhaust ventilation) as specified in a workplace risk assessment. Technical measures and appropriate operations should be given priority over the use of personal protective equipment. Handle in accordance with good industrial hygiene and safety practice.

Personal protective equipment

Eye face protection: Wear safety glasses with side shields. An emergency eye wash station should be available.

Skin protection: Handle with gloves. The selected gloves must comply with the specifications in EC Directive 89/686/EEC and the related standard EN374 or applicable federal, state and national legislation.

Protective clothing: Use impervious, disposable clothing to prevent skin contact. The type should be selected according to concentrations, quantities and duration of handling at the specific workplace.

Respiratory protection: Required when dusts are generated. Where risk assessment shows that an air-purifying respirator is appropriate, use filter of type P3 (EN143) or N100 (NIOSH) or types recommended in applicable federal, state and national legislation.

Environmental exposure controls: Avoid release to the environment.

Stability and reactivity

REACTIVITY

No known reactivity hazards under normal conditions.

CHEMICAL STABILITY

The substance is chemically stable at standard room temperature conditions, generally 15 to 25C.

POSSIBILITY OF HAZARDOUS REACTIONS AND CONDITIONS TO AVOID

Not expected to occur

INCOMPATIBLE MATERIALS

Strong oxidants; strong acids or bases.

HAZARDOUS DECOMPOSITION PRODUCTS

Carbon oxides (COx) and hydrogen chloride (HCl) may be formed.

Disposal considerations

WASTE TREATMENT METHODS

Dispose waste at authorized plant, in accordance with Directive 2008/98/EC and/or applicable federal, state, national or local legislation.

INFORMATION ON RECYCLING AND METHODS OF DISPOSAL FOR INDUSTRY

Avoid dust generation and inhalation of dust. Avoid contact with eyes, skin and other mucous membranes. Wear all recommended personal protective equipment. Wash thoroughly after handling. Dispose waste at authorized plant, in accordance with applicable national, federal, state or local legislation. Disposal should be sent to external waste handling company for incineration. Do not empty into drains or watercourses.

INFORMATION ON RECYCLING AND METHODS DISPOSAL FOR THE PUBLIC

This substance is not for public use. It is an on-site isolated intermediate used for internal processing and therefore this entry is not applicable.
