SECTION 6: ACCIDENTAL RELEASE MEASURES

Emergency measures: Keep away from sources of ignition. Rapid evacuation personnel which divulged in the pollution area to the safety zone, and carries on the isolation, strictly limits the in/out. Advised the personnel who emergency processing should be wear self-sufficient respirator, put on anti-poison clothing, shuts off as far as possible the divulged source.

Large Spill and Leak: Dike if needed. Use water spray curtain to divert vapor drift. Use water spray to reduce vapors. Protection filed personnel .With explosion-proof Pumps shift to the tank car or the special-purpose collector, then recycling or transports to waste scene processing. 

SECTION 7 : HANDLING AND STORAGE

Handling: The operator must pass through the specialized training, strictly observes the working instruction. Suggestion operator wears mouthpiece or self-absorption filter gas mask, wear chemistry security safekeeping eyeglasses, put on anti-poison seepage work clothes, wear rubber resistant oil glove. Keep away from heat, sparks and flame, prohibiting smoking in the work area. Use defending explosion-proof ventilation system and equipment. Prevent the steam divulges to the operational site air. Avoid contact with the oxidant. Should pay attention to the speed of flow (not to surpass 5m/s) when canned, and have grounding equipment, prevent the static electricity accumulation. When transporting must lightly unload and light packs, prevents package or vessel damage, and provides the variety corresponding fire-fighting equipment and handling emergency divulged. The vessel Dumped possibly remains harmfully.

Storage: Keep container in a cool, well ventilated area. Keep away from heat, sparks and flame. The warehouse temperature do not surpass 30℃, keep the vessel seal. Should separate with the oxidant, food chemical, prohibit stores together. The illumination and ventilates equipment should be explosion-proof. Prohibited using easily produces the spark mechanical device and the tool. The store area should to have divulges emergency and appropriate accepts the material.

SECTION 11: TOXICOLOGICAL INFORMATION

(On account of unsaturated polyester resin’s molecular weight of number average is over 1,500 and it has lower solubility. It can’t be absorbed through skin absorption and permeate organism cell. So it cann’t display toxicity. Because of unsaturated polyester resin’s low fluidity, it has litter damage to the environment. According to American FDA and EPA research, Australian EPA think non-ionic polymer which average molecular weight is over 1,000 concerns degree should be lower. But unsaturated polyer resin’s diluent is styrene, its toxictity and Ecological information is relevant to styrene.)

Acute toxicity: Acute oral toxicity (LD50)  265mg/kg [Mouse]

Acute toxicity of the vapor (LC50)  12mg/m3/4h [Mouse]

Acute Poisoning: In case of high concentration contact, may lead to eye and upper respiratory tract irritant. May cause ophthalmalgia, lacrimation, rhinorrhea, sneezing, pharyngodynia and cough. Continues the headache, dizziness,nausea, vomits, the whole body feels weak and so on; Serious may have the dizziness, staggering gait. When the eye is polluted by styrene, it may send burns.

Chronic Poisoning: At times the symptoms of tiredness,response slowing and memory decreasing emerged in long-term exposure in the surrounding of 100ppm.Red and white blood cell population varied,as well as peripheral nerve and sense organ.Other changes of liver was caused by nutritional marasmus and the marasmus induced by total metabolism changing,other biocatalysts also varied.

Biodegradation: It has 2.3 – 4.3% to degeneration in the earth’s surface of each week, and has 2.8-12.0% to degeneration in the soil, Styrene has a 93% to be possible to degrade in 16 weeks and degradation product is carbon dioxide and water

Non- biodegradation: Styrene can very quickly react with the OH free radical and O3 in the air, the reaction half-life is 5h, the soil migration ratio is slightly, KOC is 270-550.

The biology concentrates the nature: BCF, 13.5 goldfishes, because of relative high water-solubility, it can not accumulate in the biological tissue.
