Synthetic wollastonite

Guidance on Safe Use

First-aid measures

- General advice: No acute and delayed symptoms and effects are observed.

- Following inhalation: Move affected person to fresh air and keep warm and at rest in a position comfortable for breathing. Get medical attention if any discomfort continues.

- Following skin contact: Wash skin thoroughly with soap and water. Use suitable lotion to moisturise skin.

- Following eye contact: Do not rub eye. Rinse with copious quantities of water and seek medical attention if irritation persists.

- Following ingestion: Give plenty of water to drink. Never give anything by mouth to an unconscious person.

- Most important symptoms and effects: The severity of the symptoms described will vary dependent on the concentration and the length of exposure.

Fire-fighting measures

- Suitable extinguishing media: This product is non-combustible. No specific extinguishing media is needed.

- Unsuitable extinguishing media: None specified

- Special hazards arising from the substance or mixture: Non combustible. No hazardous thermal decomposition.

- Advice for fire fighter: No specific fire-fighting protection is required. Use an extinguishing agent suitable for the surrounding fire.

Accidental release measures

- Personal precautions: Avoid airborne dust generation, wear personal protective equipment in compliance with national legislation.

- Environmental precautions: Do not discharge into drains or watercourses or onto the ground.

- Methods and material for containment and cleaning up: Remove spillage with vacuum cleaner. If not possible, collect spillage with shovel, broom or the like. This product should be handled with care to avoid dust generation.

Handling and storage

- Precautions for safe handling:

Usage precautions:

Avoid airborne dust generation. Provide appropriate exhaust ventilation at places where airborne dust is generated. In case of insufficient ventilation, wear suitable respiratory protective equipment. Handle packaged products carefully to prevent accidental bursting. If you require advice on safe handling techniques, please contact your supplier. Do not eat, drink and smoke in work areas; wash hands after use; remove contaminated clothing and

protective equipment before entering eating areas.

Advice on general occupational hygiene:

Keep dust levels to a minimum. Minimize dust generation. General occupational hygiene

measures are required. These include good personal and housekeeping practices (i.e. regular

cleaning with suitable cleaning devices). Shower and change clothes at end of work shift.

Change work clothing daily before leaving workplace.

- Conditions for safe storage, including any incompatibilities: Store in a dry covered area. 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.

Exposure controls / personal protection

1. Technical protection measures

Control parameters

Occupational exposure limits

A European Binding OEL (Occupational Exposure Limit) for respirable crystalline silica dust is set at 0.1 mg/m³ in the Directive (EU) 2017/2398, measured as an 8-hour TWA (Time Weighted Average).

Quartz

Long-term exposure limit (8-hour TWA): WEL 0,1 mg/m³ respirable dust

Inorganic dust

Long-term exposure limit (8-hour TWA): WEL 4 mg/m³ respirable dust

Long-term exposure limit (8-hour TWA): WEL 10 mg/m³ inhalable dust

WEL = Workplace Exposure Limit

2. Organisational protection measures

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. Remove and wash soiled clothing.

3. Hand protection

Chemical-resistant, impervious gloves complying with an approved standard should be worn if

a risk assessment indicates skin contact is possible. It is recommended that gloves are made

of the following material: Polyvinyl chloride (PVC). Rubber (natural, latex).

4. Body protection

For skin, normal work clothes are appropriate.

5. Eye protection

Eyewear complying with an approved standard should be worn if a risk assessment indicates

eye contact is possible. The following protection should be worn: Chemical splash goggles or

face shield. Contact lenses should not be worn when working with this product.

6. Respiratory protection

Local ventilation to control airborne dust levels below occupational exposure limits is

recommended. In case of exposure, where engineering controls are insufficient, the use of

Respiratory Protective Equipment (RPE) is recommended. A risk assessment process must

be followed to ensure adequate protection from the airborne dust. The type of RPE must suit

the work situation and the specific requirements of the wearer. Other environmental conditions should also be considered. The minimum “Assigned Protection Factor” (APF) required will depend on the measured or predicted occupational exposure levels divided by the OEL detailed above. Filters specified as FFP2 and P2 have an APF of 10. Correctly fitted, these would reduce the exposure to the wearer down to one tenth of the working atmosphere. Depending on the assessment of the exposure, a lesser or higher efficiency of filter may be required. The manufacturer’s instructions and regulatory guidance regarding duration of use and correct fitting should be followed. The wearer of the selected RPE should receive training before use.

7. Hygiene measures

When using do not eat, drink or smoke. Wash at the end of each work shift and before eating,

smoking and using the toilet. Use appropriate skin cream to prevent drying of skin.

8. Environmental exposure controls

All ventilation systems should be filtered before discharge to atmosphere.
