See Toxicological Information (Section11)

Potential environmental effects

See Ecological Information (Section 12)

Section 4: First Aid Measures
If accidental overexposure is suspected

Eye(s) Contact: Check for and remove any contact lenses. In case of contact, immediately flush eye with plenty of water for at least 15 minutes. Cold water may be used. Get medical attention immediately.

Skin Contact: In case of contact, immediately flush skin with plenty of water for at least 15 minutes. Cold water may be used. Remove contaminated clothing and shoes and wash before reuse. Get medical attention immediately
Inhalation: If inhaled, remove to fresh air. If not breathing, give artificial respiration. Get medical attention immediately.

Ingestion: If swallowed, do not induce vomiting unless directed to do so by medical personnel. Never give anything by mouth to and unconscious person. Loosen tight clothing such as a collar, tie, belt or waistband. Get medical attention immediately.

Note to physician

Treatment: NIF

Medical Conditions generally Aggravated by Exposure: Repeated exposure of the eyes to a low level of dust can produce eye irritation. Repeated skin exposure can produce local skin destruction, or dermatitis. Repeated inhalation of dust can produce varying degree of respiratory irritation or lung damage. Repeated exposure to a highly toxic material may produce general deterioration of health by an accumulation in one or many human organs.

Section 6: Accidental Release Measures
Steps to be Taken in Case Material is Released or Spilled: Evacuate the area of all unnecessary personnel. Wear suitable protective equipment.  Eliminate any ignition sources until the area is determined to be free from explosion or fire hazards. Contain the release and eliminate its source, if this can be done without risk. Take up and containerize for proper disposal.  Comply with local, state and Federal regulations on reporting releases.  Refer to regulatory information for reportable quantity and other regulatory data.
Waste Disposal Methods: Dispose of waste according to Federal, State and Local Regulations.

Section 7: Handling and Storage

Section 8: Exposure Controls / Personal Protection
Engineering Controls

Ventilation required:  Material should be handled or transferred in an approved fume hood or with adequate ventilation.

Personal Protection Equipment

Respiratory protection: If workplace exposure limit(s) of product or any component is exceeded (see TLV/PEL), a NIOSH/MSHA approved air supplied respirator is advised in absence of proper environmental control. OSHA regulations also permit other NIOSH/MSHA respirator (negative pressure type) under specified conditions (see your safety equipment supplier). Engineering and/or administrative controls should be implemented to reduce exposure.

Protective gloves: Nitrile or equivalent.
Skin protection: Impervious, protective clothing.
Eye protection: Safety glasses with side shields must be worn at all times.
Additional clothing and/or equipment: Eyewash and safety equipment should be readily available.
