Will Not Occur

Conditions to Avoid – Elevated temperatures, direct sunlight, sources of ignition, low oxygen environments. Hazardous exothermic polymerization can occur if exposed to elevated temperatures for periods of time. Air space oxygen above the product is vital to keep fomulatory inhibitors active.

Incompatibility (Materials to Avoid) – Oxidizing agents, free-radical initiators, reducing metal oxides. Do not allow to contact or store in aluminum, mild steel, rusty steel, copper or alloys of tin vessels.

Hazardous Decomposition or Byproducts – Combustion/exothermic polymerization will generate oxides of carbon, arid smoke and irritating fumes.

Signs and Symptoms of Exposure: Eyes— Causes eye irritation. Skin—may cause skin irritation, may cause allergic skin reaction. Inhalation— May cause respiratory tract irritation.

Medical Conditions Generally Aggravated –

Emergency and First Aid Procedures. Eyes— Flush with copious amounts of water, preferably, luke warm water for at least 15 minutes, holding eyelids open all the time. Get medical attention. Skin— Remove contaminated clothing and shoes. Rinse immediately with plenty of water and then wash with soap. Get medical attention if symptoms occur. Inhalation— Remove to fresh air. If symptoms develop and persist, get medical attention. Ingestion— Do not induce vomiting. Give plenty of water to drink.

Section VII – Precautions For Safe Handling and Use

Steps to be Taken in Case Material is Released or Spilled. Exposure Controls: Ventilate area. Evacuate all personnel. Use barriers to prevent unauthorized entry into contaminate areas. Do not allow spill to enter drains and watercourses. Personal Protection: Wear suitable respiratory protection for large spillages and in confined spaces, e.g. EN405 FFA2 or EN140 A2. Wear polythene gloves. Wear chemically resistant overalls and boots. Use eye protection such as goggles to BS EN 166 Chemical Grade.

Disposal Considerations – Absorb in inert material such as sand are absorbent granules. Scoop up and place in plastic container to await transfer. Dispose in accordance with local regulations.

Precautions to be Taken in Handling and Storing – Handling- Avoid contact with eyes, skin, and clothing. Avoid breathing vapor and mist. Wash thoroughly after handling. Ensure adequate ventilation and/or use local extraction. Storage – For safe storage, store at or below 38°C (100°F). Keep in a cool, dry well-ventilated area out of direct sunlight. Keep away from sources of ignition. Store in tightly closed, labeled containers. Can be stored in LDPE containers. Do not allow to contact or store in aluminum, mild steel, rusty steel, copper or (alloys of) pr tom vessels.

Section VIII – Control Measures

Respiratory Protection (Specify Type) – If excessive inhalation in a poorly ventilated area is likely then use a respirator with filter type A.

Ventilation

Use in well ventilated areas. Use local exhaust ventilation if exposed for long periods.

Protective Gloves – Wear gloves-polythene, neoprene or nitrile. Do not use PVC or latex.

Eye Protection – Wear eye goggles, such as rated to BS EN 166.

Other protective Clothing or Equipment –If handling large quantities, wear suitable protective clothing. Ensure eye-wash facilities/station are close to hand.

Work/Hygienic Practices – Observe good hygiene. Wash hands thoroughly after eating, drinking, and using restrooms, etc. Do not smoke while using.
