3. Hazard Identification

Base:
Base resin is flammable, harmful by inhalation and irritating to eyes and skin. Strongly exothermic polymerisation may be initiated by heat, peroxides or other free radical generators.
Hardener:
The hardener is an oxidising substance, may cause fire. Irritating to the eyes and may also cause sensitisation by skin contact.
4. First Aid Measures
Inhalation:
In case of drowsiness or sickness remove to fresh air, keep patient warm and at rest. If unconscious, turn to the recovery position. Seek medical assistance.
Skin Contact: Promptly remove contaminated clothing and wash the affected area with
plenty of soap and water to ensure all traces of product are removed, then rinse thoroughly. Any contaminated clothing must be thoroughly cleaned before re-using. Seek medical advice if irritation persists.
Eye Contact: Flush with copious amounts of clean water for at least 15 minutes, with the
eye lids held open. Seek medical attention.
Ingestion:
Wash out mouth with water. Keep patient at rest and obtain medical attention. DO NOT INDUCE VOMITING.
5. Fire Fighting Measures
Suitable Extinguisher Media:
Alcohol-resistant foam, dry powder, carbon dioxide or sand.
Unsuitable Extinguishing Media:
Ref: HSD/F6
Issue No: 7
Date of Issue: 18th November, 2005

Exposure Hazards:
May give off toxic fumes if heated or involved in a fire, including carbon monoxide, carbon dioxide, benzoic acid, benzene and phenyl benzoate.
Special Protective Equipment:
Full face, positive pressure, self-contained breathing apparatus and full protective clothing.
6. Accidental Release Measures
Personal Precautions:
Wear protective equipment as specified in Section 8. Do not eat, drink or smoke. Avoid contact with skin and eyes. Avoid breathing vapours and dust. Eliminate all ignition sources.
Environmental Precautions:
Eliminate all ignition sources. Keep people and animals away. Prevent entry into drains, sewers and watercourses. If spillage enters drains leading to sewerage works inform the local water company. If spillage enters rivers or watercourses inform the Environment Agency.
Spillages:
Cordon off area. Absorb/contain spillage using inert absorbent granules, sand or earth. Transfer collected material to heavy-duty plastic/steel drums and keep in a well ventilated place for subsequent safe disposal. See Section 13.
7. Handling and Storage
Handling:
No specific precautions required when handling unopened containers; follow any relevant manual handling guidance. Refer to Sections 6 and 8 if exposure to product is possible. Take precautionary measures against static discharges. Wash thoroughly with soap and water before eating, drinking or smoking, and after work
Storage:
Store in original containers in a well ventilated area away from heat, sunlight, ignition sources or open flame. Keep away from reducing agents (eg amines), acids, alkalis and heavy metal compounds (eg accelerators, driers, metal soaps).
8. Exposure Controls / Personal Protection
Occupational Exposure Standards:
Styrene - 8 hour TWA 100ppm, 15 min STEL 250ppm This exposure limit must not be exceeded at any time during the exposure period. Talc - 8 hour TWA 1mg/m3 (respirable) OES. General Dust - 8 hour TWA 10mg/m3 (total inhalable), 4mg/m3 (respirable) OES. While the base component contains talc and general dusts, which have an Occupational Exposure Standards assigned to them, these materials are not present in powder form and therefore do not present an inhalation hazard. Dibenzoyl Peroxide - 8 hour TWA 5mg/m3 OES. Diisobutyl Phthalate - 8 hour TWA 5mg/m3 OES. Ref: HSD/F6 Issue No: 7 Date of Issue: 18th November, 2005 While the hardener component contains dibenzoyl peroxide and diisobutyl phthalate, it is very unlikely that these Occupational Exposure Standards would be exceeded under foreseeable conditions of use.
Engineering Control Measures:
Refer to any applicable COSHH assessments. Engineering controls should be used where practicable in preference to personal protection and may include physical containment and good ventilation.
Respiratory Protection:
If levels of styrene exceed the above limits, or in the unlikely event that the limits for dibenzoyl peroxide or diisobutyl phthalate are exceeded, use an approved respirator fitted with an appropriate gas cartridge (organic substance). All items must conform to EN149 and should be suitable for the levels of contamination present in the workplace.
Hand Protection:
Wear Neoprene, Nitrile or PVC gloves or gauntlets. These must be manufactured to EN374. The material breakthrough time should be stated by the glove manufacturer, and must be observed at all times.
Eye Protection:
If eye contact with the product is likely chemical resistant goggles conforming to BS 2092 should be worn.
Body Protection:
Wear suitable impervious, chemical resistant overalls.
Foot Protection:
Wear chemical resistant safety footwear.
Hygiene Measures:
Handle in accordance with good industrial hygiene and safety practice.

10. Stability and Reactivity
Stability:
Stable under normal conditions (see Section 7). A dangerous self-accelerating decomposition reaction and, under certain circumstances, explosion or fire can be caused by direct contact with incompatible substances or by thermal decomposition at and above the SADT of 50oC.
Materials to Avoid: Base:
Acids, alkali, heavy metals and reducing agents. Avoid contact with rust, iron and copper. Do not mix with peroxide accelerators. Do not mix with reducing agents. Avoid temperatures above 25oC. Avoid shock and friction.
Hazardous Decomposition Products: Carbon monoxide, carbon dioxide, benzoic acid,

11. Toxicological Information
There is no data available on the product itself.

12. Ecological Information
There is no data available on the product itself.
The following data applies to un-mixed material only, as once the base and hardener are
combined the harmful constituents will react to form an inert product.
Both styrene and dibenzoyl peroxide are readily biodegradable.
Dibenzoyl peroxide (78%)
