1,2-Naphtoquinonediazide-5-sulfonylchloride (or sulfonic acid) esters with 4,6-bis(1-(4-hydroxyphenyl)-1-methylethyl)-1,3-dihydroxybenzene

Guidance on Safe Use

First-aid measures

- General advice: Get medical advice/attention
- Following inhalation: Allow victim to breathe fresh air. Allow the victim to rest. Obtain medical attention if breathing difficulty persists.
- Following skin contact: Remove affected clothing and wash all exposed skin area with mild soap and water, followed by water rinse.
- Following eye contact: In case of contact with eyes, rinse immediately with plenty of water and seek medical advice.
- Following ingestion: If swallowed, immediately administer water (1/2 liter) only if victim is completely conscious/alert. Do not induce vomiting.
- Most important symptoms and effects:

Fire-fighting measures

- Suitable extinguishing media: Foam. Dry chemical. Carbon dioxide. Use extinguishing media appropriate for surrounding fire.
- Unsuitable extinguishing media:
- Special hazards arising from the substance or mixture:
- Advice for fire fighter: Do not enter fire area without proper protective equipment, including respiratory protection. Pressure demand self-contained breathing apparatus should be provided to fire fighters in building or confined area where the material is stored. Avoid fire-fighting water to enter environment. Exercise caution when fighting any chemical fire.
Water should be used to keep exposed containers cool.

Accidental release measures

- Personal precautions: Supply fresh air. Equip cleanup crew with proper protection.
- Protective equipment and emergency procedures: Respiratory protection equipment may be necessary.
- Environmental precautions: Avoid release to the environment. Prevent entry to sewers and public waters.
- Methods and material for containment and cleaning up: Minimize generation of dust. Use suitable disposal containers.

Handling and storage

- Precautions for safe handling: Minimize generation of dust. Local exhaust and general ventilation must be adequate to meet exposure standards. Close container tightly after use.
- Conditions for safe storage, including any incompatibilities: Maintain the storage temperature below 40°C. This storage temperature is intended to cover HSE-purposes and is valid within the period: shelflife + 3 months. Store in a well-ventilated place. Keep container tightly closed.
