4. First aid

 4.1 First aid description

For the finished material, no special measures are required, but there are some requirements for processing and preparation, as indicated below:

General recommendations: Have the label or safety data sheet to hand when you call the emergency number or consult a doctor. Move the affected person away from the source of the exposure. Give them fresh air and rest. Do not give the victim anything to drink if they are unconscious.

The symptoms of poisoning may appear after exposure, meaning that if there is any concern or if an illness persists, call a doctor and show them the SDS for this product.

 Inhalation: Do not inhale dust produced by material processing. If poisoning symptoms appear, move the affected person out of the exposure area and get them some fresh air. Use assisted respiration if the victim is having a serious reaction. Call for medical attention if the symptoms worsen or persist.

 Contact with skin: Wash thoroughly with soap and water.

Contact with eyes: Rinse eyes with plenty of room-temperature water for at least 15 minutes. Prevent the affected person from rubbing or closing their eyes. If the victim wears contact lenses, these should be removed unless stuck to the eyes, as failure to do so may cause additional injury. Call for medical attention if the symptoms worsen or persist.

4.2 Main symptoms; acute and delayed effects

Inhalation: During the mechanical processing of this product, particularly if the processing recommendations of using water and suitable air filtering and venting systems are not followed, a fraction of fine particles of mineral dust and crystalline silica may be suspended in the air. Prolonged contact and/or large-scale inhalation of this respirable dust can cause pneumoconiosis, pulmonary fibrosis (commonly known as silicosis), lung cancer, chronic obstructive pulmonary disease and kidney disease. The main symptoms of silicosis are a cough and difficulty breathing (see section 11).

4.3 Medical attention and special treatments that should be provided immediately

If uncertain or if symptoms persist, seek medical attention.

5. Fire suppression measures

 5.1 Extinguishers

Fire resistance: EN 13501-1 Category: A2, s2, d0

Suitable fire-fighting tools: Any suitable tool for fighting the type of fire at hand. Polyvalent powder extinguishers are recommended.

5.2 Hazards specific to the substance or mixture

Not flammable. No dangerous thermal decomposition.

5.3 Recommendations for fire-fighters

7. Handling and storage

7.1 Safe handling precautions

Manual handling

Handling Silestone® requires no special measures. The user should take responsibility for carrying out a risk evaluation in accordance with workplace risk prevention regulations.

It is advisable to take the precautions listed below:

  • Safe handling systems (crane, racks with safety bars, etc.) should be used. Slings should be durable and well protected, as this material has greater cutting capabilities than natural stone;
  • Personal Protective Equipment should be used. Wear a helmet, safety shoes, safety glasses and gloves while handling and storing Silestone®.

Processing and installation:

The employers of professionals who process the material should equip the workplace with the relevant occupational health and safety measures for limiting worker exposure to respirable crystalline silica and ensuring that the workplace complies with applicable local regulations on this subject.

It is very important that mechanical processing of the material during processing and installation be carried out using tools with integrated water delivery system, or with on-tool dust extraction system. Uncontrolled dry mechanical processing must be avoided, as the dust produced contain respirable crystalline silica (SiO2).

Dust exposure should be monitored and controlled using appropriate control measures, such as:

  • Machines and tools with water supply systems or the “wet method”, with an appropriate water treatment system.
  • Natural and/or forced-air ventilation systems that ensure air renewal in work areas.
  • Cleaning and maintenance. Use of vacuum and/or water cleaning systems; sweeping and using compressed air is to be avoided, as are other methods that may cause dust to be airborne. Put preventive maintenance programmes in place at facilities to ensure suitable tidiness, cleanliness and operational conditions for work equipment.

For working with the material, it is advisable to consult the “Good Practices Guide”, available via the website osh.cosentino.com or upon request from the supplier of this SDS.

However, in no case are these measures and guide exhaustive or substitutive of the legal obligations in regards of health and safety under the applicable local regulations.

7.2 Safe storage conditions, including possible incompatibilities

No specific conditions are needed for safe storage, save storage in an appropriately enclosed and covered area.

Avoid hard impacts that could break the material.

The product is not covered by Directive 2012/18/EU (SEVESO III).

7.3 Specific end uses

There are no specific recommendations for end uses.

11. Toxicity information

11.1 Toxicological effects

a) Acute toxicity: Does not meet classification criteria 

Acute toxicity estimate (ATE) of the mixture
Oral ATE >2000 mg/Kg
Dermal ATE >2000 mg/Kg
Inhalation ATE No information available
Crystalline silica (SiO2): Quartz, Cristobalite
Oral LD50 >2000mg/Kg weight (rat)
Dermal LD50 >2000 mg/Kg weight (rabbit)
Inhalation LC50 No specific data are available on acute toxicity that would permit a 100% categorical decision on the classification for acute toxicity by inhalation for any kind of crystalline silica. No acute toxicity by inhalation is expected based on extrapolations of OECD-compliant studies carried out with a substance containing 45% cristobalite with no sign of lethality. As a result, animal welfare concerns make further experiments unjustifiable.

 b) Dermal corrosion or irritation:

According to current information, the classification criteria are not met.

 c) Serious eye injury or eye irritation:

According to current information, the classification criteria are not met.

 d) Respiratory or dermal sensitivity:

According to current information, the classification criteria are not met.

e) Specific Target Organ Toxicity (STOT) – repeated exposure:

The respirable dust from the products Silestone Q10 are classified as STOT RE 2 with a crystalline silica content of 1-10%. The respirable dusts from Silestone Q40, Q50 and the rest of the products are classified as STOT RE 1, with a crystalline silica content > 10%.

The prolonged and/or large-scale inhalation of the respirable fraction of mineral dust and crystalline silica (< 10μm) can cause pneumoconiosis and pulmonary fibrosis such as silicosis, as well as worsening other respiratory conditions (bronchitis, emphysema, etc.). The main symptom of silicosis is a loss of lung capacity. Prolonged or large-scale exposure to dust containing respirable crystalline silica may increase the risk of other illnesses such as chronic obstructive pulmonary disease (COPD) autoinmune diseases, and kidney disease.

f) Specific Target Organ Toxicity (STOT) – single exposure:

This product is classified as STOT SE 3 according to the criteria set out in Regulation (EC) 1272/2008.

The dust generated by the mechanical processing of this material can cause respiratory irritation if appropriate protective measures are not taken.

g) Carcinogenicity: 

  • Quartz and cristobalite (SiO2): Prolonged or large-scale exposure to dust containing respirable crystalline silica may cause lung cancer.
Material classification Directive 2004/37/CE IARC NTP OSHA ACGIH WES HCIS
Crystalline silica (quartz and cristobalite) Carcinogenic. Category 1A. Group 1. Carcinogenic to humans Known to be carcinogenic Yes. Regulated as carcinogenic A2. Suspected to be carcinogenic to humans 6.7A Confirmed carcinogenic; (r) Carcinogenic Category 1A

Depending on the colour of the Silestone® material, small amounts of titanium oxide (<2.5%) may be present in the product. These may be released into the air along with dust during mechanical processing.

Titanium dioxide: Frequent inhalation of smoke/dust for a prolonged period may raise one’s risk of developing respiratory illnesses, even though epidemiological studies carried out on titanium dioxide production workers have not been able to demonstrate this.

Evicence of carcinogenicity was reported in rodents exposed to very high concentrations. Two large epidemiological studies carried out on titanium dioxide production workers in the USA and Europe were unable to demonstrate an increased risk of lung cancer. The IARC and the European Chemicals Agency classified TiO2 as carcinogenic category 2 via inhalation. The General Court of the European Union, in its judgment of 23/11/2022, decided to revoke the classification of titanium dioxide as a category 2 carcinogen by inhalation.This modification is pending inclusion in Regulation (EC) 1272/2008.

IARC has classified TIO2 as 2B (possibly carcinogenic to humans). However, the only evidence that it is carcinogenic comes from rodents exposed to very high concentrations. Two large epidemiological studies carried out on titanium dioxide production workers in the USA and Europe were unable to demonstrate an increased risk of lung cancer.
