First-aid measures

Take off contaminated clothes and shoes immediately. In case of accident or if you feel unwell, seek medical advice immediately (show the label where possible). In case of shortness of breath, give oxygen. Keep victim warm.
Inhalation:
Move to fresh air. For breathing difficulties, oxygen may be necessary. Induce artificial respiration with the aid of a pocket mask equipped with a one way valve or other proper respiratory medical device. Do not use mouth to mouth method if victim inhaled the substance. Get medical attention if symptoms occur.
Skin contact:
Remove and isolate contaminated clothing and shoes. Wash off with warm water and soap. For minor skin contact, avoid spreading material on unaffected skin. Get medical attention if irritation develops and persists.
Eye contact:
Immediately flush eyes with plenty of water for at least 15 minutes. Remove contact lenses, if present and easy to do. Get medical attention if symptoms occur. Continue rinsing.
Ingestion:
IF SWALLOWED: Immediately call a POISON CENTER or doctor/physician. Never give anything by mouth to a victim who is unconscious or is having convulsions. If swallowed, rinse mouth with water (only if the person is conscious). Do not induce vomiting without advice from poison control centre. If vomiting occurs, keep head low so that stomach content doesn't get into the lungs.
Most important symptoms and effects, both acute and delayed: Exposure to powder or dusts may be irritating to eyes, nose and throat.
Indication of any immediate medical attention and special treatment needed: In case of shortness of breath, give oxygen. Keep victim warm. Keep victim under observation. Provide general supportive measures and treat symptomatically. Symptoms may be delayed.

Fire-fighting measures

General fire hazards:
High concentration of airborne dust may form explosive mixture with air. Ensure that good housekeeping practices are followed as well as applicable guidelines such as the National Fire Protection Association [NFPA] 654, "Prevention of Fire and Dust Explosions from the Manufacturing, Processing, and Handling of Combustible Particulate Solids". The Minimum Ignition Energy for some organic solids as a dust may be as low as 3 mJ [millijoules]. The Minimum Explosive Concentration for some organic solids as a dust may be as low as 0.025 oz/ft3 or ~20 g/m3.
Extinguishing media:
Suitable extinguishing media: Water fog; Foam; Dry chemical powder; Carbon dioxide (CO2).
Unsuitable extinguishing media: Do not use water jet as an extinguisher, as this will spread the fire.
Special hazards arising from the substance or mixture: Fire may produce irritating, corrosive and/or toxic gases.
Advice for fire-fighters: Special protective equipment for fire-fighters
Fire-fighters must use standard protective equipment including flame retardant coat, helmet with face shield, gloves, rubber boots, and in enclosed spaces, SCBA. Structural fire-fighters protective clothing will only provide limited protection.
Special firefighting procedures: Cool containers exposed to heat with water spray and remove container, if no risk is involved. High concentration of airborne dust may form explosive mixture with air. Ensure that good housekeeping practices are followed as well as applicable guidelines such as the National Fire Protection Association [NFPA] 654, "Prevention of Fire and Dust Explosions from the Manufacturing, Processing, and Handling of Combustible Particulate Solids". Vapours are heavier than air and may travel along the ground to some distant source of ignition and flash back.

Accidental release measures

Personal precautions, protective equipment and emergency procedures:
For non emergency personnel: Keep people away from and upwind of spill/leak. Avoid inhalation of vapours and spray mists. Remove all sources of ignition. Keep out of low areas. Do not touch damaged containers or spilled material unless wearing appropriate protective clothing.
For emergency responders: Do not touch damaged containers or spilled material unless wearing appropriate protective clothing. Keep upwind. Keep out of low areas. Avoid inhalation of vapours and spray mists. Wear appropriate protective equipment and clothing during clean up. Remove all sources of ignition. Ventilate closed spaces before entering them.
Environmental precautions: Prevent further leakage or spillage if safe to do so. Eliminate sources of ignition. Ventilate the contaminated area. Prevent spreading over a wide area (e.g. by containment or oil barriers). Prevent entry into waterways, sewer, basements or confined areas. In the event of a spill or accidental release, notify relevant authorities in accordance with all applicable regulations.
Methods and material for containment and cleaning up: Eliminate ignition sources including sources of electrical, static or frictional sparks. Ventilate the contaminated area. Avoid dust formation. Wear appropriate protective equipment and clothing during clean up.
Large Spills: Dike the spilled material, where this is possible. Cover with plastic sheet to prevent spreading. Clean surface thoroughly to remove residual contamination.
Small Spills: Sweep up or vacuum up spillage and collect in suitable container for disposal. Clean surface thoroughly to remove residual contamination.

Handling and storage

Precautions for safe handling: Do not handle, store or open near an open flame, sources of heat or sources of ignition. Protect material from direct sunlight. Use good personal hygiene practices Guard against dust accumulation of this material. Avoid breathing dust/fume/gas/mist/vapours/spray. Wear personal protective equipment. Do not use in areas without adequate ventilation. Avoid prolonged exposure. Wash thoroughly after handling. "Empty" containers retain product residue (liquid or vapour) and can be dangerous. Do not reuse empty containers.
Conditions for safe storage, including any incompatibilities: Guard against dust accumulation of this material. Keep away from heat, sparks and open flame. Keep containers tightly closed in a dry, cool and well ventilated place. Store in a closed container away from incompatible materials. Prevent electrostatic charge build up by using common bonding and grounding techniques. Use care in handling/storage.

Exposure controls / personal protection

- Containment as appropriate;
- Minimise number of staff exposed;
- Segregation of the emitting process;
- Effective contaminant extraction;
- Good standard of general ventilation;
- Minimisation of manual phases;
- Avoidance of contact with contaminated tools and objects;
- Regular cleaning of equipment and work area;
- Management/supervision in place to check that the RMMs in place are being used correctly and OCs followed;
- Training for staff on good practice;
- Good standard of personal hygiene.
The following personal protective equipments (PPE) are recommended for substances of moderate hazard (due to skin sensitization properties):
- Substance/task appropriate gloves;
- Skin coverage with appropriate barrier material based on potential for contact with the chemicals;
- Substance/task appropriate respirator;
- Optional face shield.

No local eye hazard is identified for biphenyl-4,4'-diol

Stability and reactivity

Stable under the reccomended condition of storage.

Disposal considerations
