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.

Symptoms: Cough, Dyspnoea

Skin contact

Rinse skin with water/shower. In case of skin irritation, consult a physician.

Eye contact

In case of contact with eyes flush immediately with plenty of flowing water for 10 to 15 minutes holding eyelids apart and consult an ophthalmologist.

Symptoms: Risk of blindness, Risk of serious damage to eyes

Ingestion

Rinse mouth. Call a doctor if you feel unwell.

05

Firefighting Measures

Extinguishing media, specific hazards, and firefighter protection

Suitable media

co-ordinate firefighting measures to the fire surroundings! dry extinguishing powder, D-powder, dry sand

Unsuitable media

water

Specific hazards

Water-reactive (in contact with water releases flammable gases). Non-combustible.

Instructions

Fight fire with normal precautions from a reasonable distance.

Firefighter Protection

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 dust.

Environmental

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

07

Handling and Storage

Safe handling precautions, storage conditions, and workplace requirements

Handling

Provision of sufficient ventilation. Avoid dust formation.

Storage

Store in a dry place. Keep container tightly closed. Keep under inert gas.

Hygiene

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

Fire prevention

When using do not smoke.

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. For special purposes, it is recommended to check the resistance to chemicals of the protective gloves mentioned above together with the supplier of these gloves. The times are approximate values from measurements at 22 °C and permanent contact. Increased temperatures due to heated substances, body heat etc. and a reduction of the effective layer thickness by stretching can lead to a considerable reduction of the breakthrough time. If in doubt, contact manufacturer. At an approx. 1.5 times larger / smaller layer thickness, the respective breakthrough time is doubled / halved. The data apply only to the pure substance. When transferred to substance mixtures, they may only be considered as a guide. Type of material: NBR (Nitrile rubber). Material thickness: >0,11 mm. Breakthrough times of the glove material: >480 minutes (permeation: level 6).

Eyes

Use safety goggle with side protection.

Respiratory

Respiratory protection necessary at: Dust formation. Particulate filter device (EN 143). P2 (filters at least 94 % of airborne particles, colour code: White).

Skin/Body

Take recovery periods for skin regeneration. Preventive skin protection (barrier creams/ointments) is recommended.

Environmental

Keep away from drains, surface and ground water.
