Firefighting Measures

Extinguishing media, specific hazards, and firefighter protection

Suitable media

Foam Carbon dioxide (CO2) Dry powder

Unsuitable media

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

Specific hazards

Combustible. Pay attention to flashback. Vapors 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

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

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

08

Exposure Controls / PPE

Occupational exposure limits, engineering controls, and protective equipment

Hands

Full contact: Material: Nitrile rubber, Minimum layer thickness: 0,4 mm, Break through time: 480 min, Material tested: Camatril® (KCL 730 / Aldrich Z677442, Size M). Splash contact: Material: Nitrile rubber, Minimum layer thickness: 0,11 mm, Break through time: 30 min, Material tested: KCL 741 Dermatril® L. This recommendation applies only to the product stated in the safety data sheet, supplied by us and for the designated use. When dissolving in or mixing with other substances and under conditions deviating from those stated in EN 16523-1 please contact the supplier of CE-approved gloves (e.g. KCL GmbH, D-36124 Eichenzell, Internet: www.kcl.de).

Eyes

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

Respiratory

Recommended Filter type: Filter A (acc. to DIN 3181) for vapours of organic compounds. The entrepreneur has to ensure that maintenance, cleaning and testing of respiratory protective devices are carried out according to the instructions of the producer. These measures have to be properly documented.

Skin/Body

Flame retardant antistatic protective clothing.

Environmental

Do not let product enter drains. Risk of explosion.
