As there are many different types of release agents, the health hazards vary. Some are toxic if swallowed, moderately toxic if inhaled and slightly toxic to the skin. Older types of release agents contained hazardous air pollutants. Most release agents are flammable.
The various mould release agents are often dissolved in a solvent (e.g naptha) to make them easy to apply. However, these solvents can be hazardous. Solvents evaporate easily and this vapour can then be inhaled. Some solvents can dissolve the fat in human tissue. This means that prolonged or repeated exposure of the skin removes natural oils, resulting in dryness or cracking. Other components of mould release agents can cause irritation of the eyes, skin and throat.
Special Protection Information
Respiratory Protection: Adequate ventilation must be provided if solvent based release agents are being used. If above the NOHSC exposure standard, use SA approved respiratory protective equipment.
Eye Protection: Use SA approved chemical splash goggles.
Protective Clothing: Wear chemical resistant gloves such as butyl rubber or neoprene rubber gloves. Apply barrier creams to un-covered skin. Wear full length trousers and long sleeved shirts and safety boots.
CONSULT SAFETY EQUIPMENT SUPPLIERS FOR RECOMMENDATIONS.
Effects of Exposure
Eyes: May cause irritation and redness.
Inhalation: May cause irritation of the respiratory tract. Frequent and prolonged exposure to high concentrations of solvent vapours may result in loss of coordination, dizziness, headaches, nausea, vomiting and possible unconsciousness.
Skin: Prolonged and/or frequent contact with solvent-based agents can result in defatting of the skin, possibly leading to other dermatitic effects.
Swallowing: May cause gastrointestinal irritation.
First Aid Procedures
Eyes: Flush with water for at least 15 minutes.
Inhalation: Remove to fresh air. If breathing is difficult, seek immediate medical assistance.
Skin: Remove contaminated clothing for laundering. Wash with soap and water. Do NOT use solvents.
Swallowing: Do NOT induce vomiting. If person is conscious, they should drink large quantities of water. Seek medical advice immediately.
Spill or Leak Procedures
If solvent-based, eliminate all sources of ignition and ventilate area. Wearing protective equipment, stop spill at source, dam area and if possible pump liquid into salvage tank. Alternatively, absorb residue with vermiculite or sand. Scoop up using nonsparking tools into labelled waste container. Flush area with water, but prevent it from entering waterways. Dispose of waste in accordance with local, state and federal regulations. Reporting of spills/leaks may be required under EPA and Dangerous Goods regulations.
Fire Extinguishing Procedures
Wear protective clothing and equipment including self-contained breathing equipment. In general, use foam or carbon dioxide to put out fires (Refer to MSDS). Cool fire-exposed containers with water spray.
Storage and Handling Procedures
Store in properly closed, labelled containers in a cool area, fitted with floor level and breathing zone ventilation to remove vapours which collect at these levels. Ensure all sources of ignition are eliminated. Keep away from strong oxidizing agents. Do not transfer to unmarked containers. Do not transfer to unapproved plastic containers. Open containers outside to allow venting of any vapours, especially if warmed. Earth containers when pouring to prevent the discharge of static electricity.
