First Aid Measures

Emergency procedures for chemical exposure incidents

Inhalation

Move the affected person away from the contaminated area and into the fresh air.

Skin contact

No special first aid measures necessary.

Eye contact

Rinse with copious quantities of water and seek medical attention if irritation persists.

Ingestion

No first aid measure required.

05

Firefighting Measures

Extinguishing media, specific hazards, and firefighter protection

Suitable media

No specific extinguishing media is needed.

Unsuitable media

No restriction on the extinguishing media to be used.

Not combustible.

Firefighter Protection

No specific fire-fighting protection is required.

06

Accidental Release Measures

Spill cleanup procedures, containment, and environmental protection

Emergency procedures

Avoid airborne dust generation, wear respiratory personal protective equipment in compliance with national legislation, see EN 143: 2000.

Environmental

No special requirements.

Cleanup methods

Avoid dry sweeping and use water spraying or vacuum cleaning systems (with high-efficiency particulate air filter) to prevent airborne dust generation.

07

Handling and Storage

Safe handling precautions, storage conditions, and workplace requirements

Handling

Avoid airborne dust generation. Provide appropriate exhaust ventilation at places where airborne dust is generated. Other suitable controls may include enclosure, isolation, water suppression, respiratory protective equipment. Handle packaged products carefully to prevent accidental bursting.

Storage

Minimise airborne dust generation and prevent wind dispersal during loading and unloading. Keep containers closed and store packaged products so as to prevent accidental bursting.

Hygiene

Do not eat, drink and smoke in work areas; wash hands after use; remove contaminated clothing and protective equipment before entering eating areas.

08

Exposure Controls / PPE

Occupational exposure limits, engineering controls, and protective equipment

Engineering

Minimise airborne dust generation. Use process enclosures, local exhaust ventilation or other engineering controls to keep airborne levels below specified exposure limits. If user operations generate dust, fumes or mist, use ventilation to keep exposure to airborne particles below the exposure limit. Apply organisational measures, e.g. by isolating personnel from dusty areas.

Hands

Appropriate protection (e.g. gloves, barrier cream) is recommended for workers who suffer from dermatitis or sensitive skin. Wash hands at the end of each work session.

Eyes

Safety glasses. Wear safety glasses with side-shields in circumstances where there is a risk of penetrative eye injuries.

Respiratory

Dust formation: dust mask. In case of prolonged exposure to airborne dust concentrations, wear a respiratory protective equipment that complies with the requirements of European or national legislation. The use of half or full face masks with filters against particles of category 2 or 3 (FP2 - FP3) is recommended. See EN 143: 2000 - Respiratory protective devices. Particle filters

Skin/Body

No specific requirement. Appropriate protection (e.g. gloves, barrier cream) is recommended for workers who suffer from dermatitis or sensitive skin. Wash hands at the end of each work session.

Environmental

Avoid wind dispersal.
