GHS Precautionary Statement Codes for This Product

Statement Text
General P102 Keep out of reach of children
General P103 Read label before use
Prevention P262 Do not get in eyes, on skin, or on clothing
Response P301+330+331 IF SWALLOWED: Rinse mouth. Do NOT induce vomiting

Potential Health Effects

Eye Contact:Eye irritant.
Skin Contact:Prolonged exposure may cause skin irritation.
Skin Absorption:Prolonged skin contact is unlikely to result in absorption of harmful amounts.
Inhalation:Brief exposure (minutes) is not likely to cause adverse effects. Excessive exposure may cause irritation to upper respiratory tract (nose and throat).
Ingestion:Low toxicity if swallowed. Small amounts swallowed incidentally as a result of normal handling operations are not likely to cause injury; however, swallowing larger amounts may cause injury.

Section 4 - First Aid Measures

Eye Contact: Check for and remove any contact lenses. In case of contact, immediately flush eyes with plenty of water for at least 15 minutes. Cold water may be used. Get medical attention if irritation occurs.
Skin Contact: Flush with plenty of soap and water for 15 minutes.
Inhalation: Remove to fresh air immediately. Give CPR/Oxygen if necessary.
Ingestion: Give patient several glasses of water, but do not induce vomiting; seek immediate medical attention.

Section 5 - Firefighting Measures

Extinguishing Media: Carbon dioxide, dry chemical, foam
Fire Fighting Procedures: Fight like a fuel oil fire. Cool fire exposed containers with water spray. Fire fighter should wear OSHA/NIOSH approved self-contained breathing apparatus. For large quantities, fight fire from a distance.
Special Protective Equipment for Firefighters: Firefighting personnel should be equipped with insulated, autonomous respiratory protection equipment.
Unusual Fire and Explosion Hazards: Closed containers exposed to high temperatures, such as fire conditions may rupture.

Section 6 - Accidental Release Measures

Steps to be Taken if Material is Released or Spilled: Wash and clean up small spills with water and detergent. Pick up large spills with inert absorbent and place in container for disposal.
Personal Precautions: Ventilation: General ventilation is required during normal use. Protective gloves: Wear appropriate impervious gloves to prevent skin contact. Eye proctection: Wear protective safety glasses with side-shields or face shield. Other protection: Wear appropriate clothing to prevent skin contact.
Environmental Precautions:

Section 7 - Handling and Storage

General Handling: Avoid inhalation of dusts created during machining. Inform personnel of risks associated with the product, the precautions to be taken and procedures to follow where an accident occurs. Observe personal hygiene rules to avoid contact with eyes and skin. Avoid inhaling vapors produced by the material, especially when heated and/or sprayed. Install showers and eye baths. Ensure sufficient ventilation, including appropriate local air extraction, in order to comply with workplace exposure limits. Where vapors could escape into the air, local specific means of ventilation will be necessary. Wash hands thoroughly at beginning of every work break and at the end of the working day. Work stations and the general working area must be kept perfectly clean. Avoid exposure to the material of person having suffered from eczema or any other skin condition.
Other Precautions:
Storage: Do not store the product above 100F (38C). Keep product away from heat, open flame, and other sources of ignition. Avoid contact with strong acids, alkali's and oxidizers. Do not freeze- separation may occur upon thawing. Cream hardener has an 18 month shelf life.

Section 8 - Precautions to Control Exposure / Personal Protection


Personal Protective Equipment (PPE):

Eye/Face Protection: Safety glasses or goggles with splash guards or rubber gloves.
Skin Protection: To prevent prolonged exposure, use rubber gloves.
Respiratory Protection: Does not require a respirator with general room ventilation. If room ventilation is lacking, use NIOSH/MSHA approved respirator to remove vapors. Use an air supplied respirator if necessary.
Hygenic Measures: Wash hands before smoking, eating or using washroom.
Other Protection Measures: Wear protective clothing as required to prevent skin contact.
Engineering Controls: Use adequate ventilation in volume and pattern to keep TLV/PEL below recommended levels. General mechanical ventilation is acceptable.
