First Aid Measures

Emergency procedures for chemical exposure incidents

Inhalation

After inhalation: fresh air. Call in physician.

Skin contact

In case of skin contact: Take off immediately all contaminated clothing. Rinse skin with water/ shower. Consult a physician.

Eye contact

After eye contact: rinse out with plenty of water. Call in ophthalmologist. Remove contact lenses.

Ingestion

After swallowing: caution if victim vomits. Risk of aspiration! Keep airways free. Pulmonary failure possible after aspiration of vomit. Call a physician immediately.

Immediate Medical Attention

Call a physician immediately.

Firefighting Measures

Extinguishing media, specific hazards, and firefighter protection

Suitable media

Carbon dioxide (CO2), Foam, Dry powder

Unsuitable media

For this substance/mixture no limitations of extinguishing agents are given.

Specific hazards

Flash back possible over considerable distance. Container explosion may occur under fire conditions. Combustible. Pay attention to flashback. Vapours are heavier than air and may spread along floors. Development of hazardous combustion gases or vapours possible in the event of fire. Forms explosive mixtures with air at ambient temperatures.

Instructions

Remove container from danger zone and cool with water.

Firefighter Protection

Stay in danger area only with self-contained breathing apparatus. Prevent skin contact by keeping a safe distance or by wearing suitable protective clothing.

06

Accidental Release Measures

Spill cleanup procedures, containment, and environmental protection

Emergency procedures

Do not breathe vapours, aerosols. Avoid substance contact. Ensure adequate ventilation. Keep away from heat and sources of ignition. Evacuate the danger area, observe emergency procedures, consult an expert.

Environmental

Do not let product enter drains. Risk of explosion.

Cleanup methods

Collect, bind, and pump off spills. Take up carefully with liquid-absorbent material (e.g. Chemizorb®). Clean up affected area.

Materials: liquid-absorbent material (e.g. Chemizorb®)

Handling and Storage

Safe handling precautions, storage conditions, and workplace requirements

Handling

Work under hood. Do not inhale substance/mixture. Avoid generation of vapours/aerosols.

Storage

Keep container tightly closed in a dry and well-ventilated place. Keep away from heat and sources of ignition. Keep locked up or in an area accessible only to qualified or authorised persons.

Hygiene

Immediately change contaminated clothing. Apply preventive skin protection. Wash hands and face after working with substance.

Fire prevention

Keep away from open flames, hot surfaces and sources of ignition. Take precautionary measures against static discharge.

08

Exposure Controls / PPE

Occupational exposure limits, engineering controls, and protective equipment

Hands

Material: Fluorinated rubber, Break through time: 480 min, Glove thickness: 0,7 mm, Manufacturer: Vitoject® (KCL 890 / Aldrich Z677698, Size M). The selected protective gloves have to satisfy the specifications of Regulation (EU) 2016/425 and the standard EN 374 derived from it.

Eyes

Use equipment for eye protection tested and approved under appropriate government standards such as NIOSH (US) or EN 166(EU). Safety glasses

Respiratory

Required when vapours/aerosols are generated. Recommendations on filtering respiratory protection are based on the following standards: DIN EN 143, DIN 14387 and other accompanying standards relating to the used respiratory protection system. Recommended Filter type: Filter A-(P3), Filter type ABEK.

Skin/Body

Flame retardant antistatic protective clothing.

Environmental

Do not let product enter drains. Risk of explosion.
