FIRST AID MEASURES4.1 Description of First Aid Measures
General Advice
If medical attention is required, show this safety data sheet to the doctor.
If Inhaled
If inhaled, move person to fresh air. If not breathing, give artificial respiration and consult a physician.
In Case of Skin Contact
Wash affected area with soap and water. Consult a physician if any exposure symptoms are observed.
In Case of Eye Contact
Immediately rinse eyes with plenty of water for at least 15 minutes. Consult a physician.
If Swallowed
Never give anything by mouth to an unconscious person. Rinse mouth with water. Do NOT induce vomiting unless advised to do so
by a physician or Poison Control Center. Seek medical attention.
4.2 Most Important Symptoms and Effects, Both Acute and Delayed
The most important known symptoms and effects are described in the labeling (see section 2.2) and/or section 11.
4.3 Indication of any Immediate Medical Attention and Special Treatment Needed
No data available
FIRE-FIGHTING MEASURES5.1 Extinguishing Media
Use water spray, alcohol-resistant foam, dry chemical or carbon dioxide
5.2 Special Hazards Arising from the Substance or Mixture
Carbon oxides, Nitrogen oxides, Sulfur oxides, Hydrogen fluoride
5.3 Advice for Firefighters
Wear self contained breathing apparatus for fire fighting if necessary. Use personal protection equipment.
5.4 Further Information No data available
ACCIDENTAL RELEASE MEASURESPersonal precautions
Wear respiratory protection. Avoid dust formation. Avoid breathing vapours, mist or gas. Ensure adequate ventilation. Evacuate
personnel to safe areas. Avoid breathing dust. Avoid contact with skin, eyes or clothing.
Environmental precautions
Prevent further leakage or spillage if safe to do so. Do not let product enter drains.
Method and materials for containment and cleaning up
Pick up and arrange disposal without creating dust. Sweep up and shovel. Keep in suitable, closed containers for disposal
HANDLING AND STORAGE7.1 Precautions for safe handling
Avoid contact with skin and eyes. Avoid formation of dust and aerosols.
Provide appropriate exhaust ventilation at places where dust is formed.
7.2 Conditions for safe storage
Keep container tightly closed in a dry and well-ventilated place.
Keep in a dry place.
Storage conditions: -20°C Freezer
7.3 Specific End Uses
For scientific research and development only. Not for use in humans or animals.
EXPOSURE CONTROLS/PERSONAL PROTECTION8.1 Control Parameters
Contains no components with established occupational exposure limits.
8.2 Exposure Controls
Appropriate Engineering Controls
A laboratory fumehood or other appropriate form of local exhaust ventilation should be used to avoid exposure.
Personal Protective Equipment
All recommendations below are advisory in nature and a risk assessment should be performed by the employer/end user prior to use
of this product. The type of protective equipment must be selected based on the amount and concentration of the dangerous
material being used in the workplace.
Eye/Face Protection
Safety goggles or face shield. All equipment should have been tested and approved under appropriate standards, such as NIOSH
(US), CSA (Canada), or EN 166 (EU).
Skin Protection
Gloves should be used when handling this material. Gloves are to be inspected prior to use. Contaminated gloves are to be
removed using proper glove removal technique so that the outer surface of the glove does not contact bare skin. Dispose of
contaminated gloves after use in compliance with good laboratory practices and local requirements.
Gloves used for incidental exposures (splash protection) should be designated as “chemical resistant” by EU standard EN 374 with
the resistance codes corresponding to the anticipated use of the material. Unrated gloves are not recommended.
Suggested gloves: AnsellPro Sol-Vex nitrile gloves style 37-175, 15 mil thickness.
Penetration time has not been determined.
Gloves used for prolonged direct exposure (immersion) should be designated “chemical resistant” as per EN 734 with the resistance
codes corresponding to the anticipated use of the material.
Suggested gloves: AnsellPro Viton/Butyl gloves style 38-612, 4/8 mil thickness.
Penetration time has not been determined.
These recommendations may not apply if the material is mixed with any other chemical, or dissolved into a solution. A risk
assessment must be performed to ensure the gloves will still offer acceptable protection.
Body Protection
Fire resistant (Nomex) lab coat or coveralls.
Respiratory Protection
Recommended respirators are NIOSH-approved N100 or CEN-approved FFP3 particulate respirators. These are to be only used as
a backup to local exhaust ventilation or other engineering controls. If the respirator is the only means of protection, a full-face
supplied air respirator must be used.
