First Aid Measures

Emergency procedures for chemical exposure incidents

Inhalation

Provide fresh air. In all cases of doubt, or when symptoms persist, seek medical advice.

Skin contact

Rinse skin with water/shower.

Eye contact

Irrigate copiously with clean, fresh water for at least 10 minutes, holding the eyelids apart. In case of eye irritation consult an ophthalmologist.

Ingestion

In case of accident or unwellness, seek medical advice immediately (show directions for use or safety data sheet if possible).

05

Firefighting Measures

Extinguishing media, specific hazards, and firefighter protection

Suitable media

water spray, dry extinguishing powder, BC-powder, carbon dioxide (CO₂)

Unsuitable media

water jet

Specific hazards

Combustible. In case of insufficient ventilation and/or in use, may form flammable/explosive vapour-air mixture. Solvent vapours are heavier than air and may spread along floors. Places which are not ventilated, e.g. unventilated below ground level areas such as trenches, conduits and shafts, are particularly prone to the presence of flammable substances or mixtures. Vapours are heavier than air, spread along floors and form explosive mixtures with air. Vapours may form explosive mixtures with air.

Instructions

Fight fire with normal precautions from a reasonable distance.

Firefighter Protection

In case of fire and/or explosion do not breathe fumes. Wear self-contained breathing apparatus.

06

Accidental Release Measures

Spill cleanup procedures, containment, and environmental protection

Emergency procedures

Use personal protective equipment as required. Avoid contact with skin, eyes and clothes. Do not breathe vapour/spray. Avoidance of ignition sources.

Environmental

Keep away from drains, surface and ground water. Retain contaminated washing water and dispose of it.

Cleanup methods

Absorb with liquid-binding material (sand, diatomaceous earth, acid- or universal binding agents).

Materials: sand, diatomaceous earth, acid- or universal binding agents

07

Handling and Storage

Safe handling precautions, storage conditions, and workplace requirements

Handling

Provision of sufficient ventilation. Avoid exposure.

Storage

Keep container tightly closed.

Hygiene

Wash hands before breaks and after work. Keep away from food, drink and animal feedingstuffs. When using do not smoke.

Fire prevention

Keep away from sources of ignition - No smoking. Take precautionary measures against static discharge.

08

Exposure Controls / PPE

Occupational exposure limits, engineering controls, and protective equipment

Hands

Wear suitable gloves. Chemical protection gloves are suitable, which are tested according to EN 374. Type of material: Butyl caoutchouc (butyl rubber). Material thickness: 0,7 mm. Breakthrough times of the glove material: >480 minutes (permeation: level 6).

Eyes

Use safety goggle with side protection.

Respiratory

Respiratory protection necessary at: Aerosol or mist formation. Type: A (against organic gases and vapours with a boiling point of > 65 °C, colour code: Brown). Observe the wear time limits according GefStoffV in combination with the rules for using respiratory protection apparatus (DGUV-Rule 112/190).

Skin/Body

Preventive skin protection (barrier creams/ointments) is recommended.

Environmental

Keep away from drains, surface and ground water.
