Specific hazards arising from the chemical
1. Liquid and vapor are flammable.
2. Moderate fire hazard when exposed to heat or flame.
3. Vapor forms an explosive mixture with air.
4. Moderate explosion hazard when exposed to heat or flame.
5. Vapor may travel a considerable distance to source of ignition.
6. Heating may cause expansion or decomposition leading to violent rupture of containers.
7. On combustion, may emit toxic fumes of carbon monoxide (CO).
Special protective equipment and precautions for fire-fighters
1. Must wear MSHA/NOISH approved positive self-contained breathing apparatus(SCBA)and protective clothing.
2. Withdrawing and isolation the possible dangerous sources, fire fighting at safe distance and suitable protection area.
Keep toxic vapors and decompositions away from inhalation, when standing at upper-wind area as well. 3. Stop leakage before fire extinguishing, otherwise it may explode again because of vapors above leakage. However, it’s not well extinguishment at nondangerous circumstance, preferring to burning up. 4. Water spray may not work effectively in terms of lower flash point. Better fire fighting performed by experienced people. 5. In huge fire at larger area, automatic water spray system should be recommended. If extinguishing is not available, evacuating people back as soon as possible. 6. Out off the space immediately, if vessel collapsed or pressure relief valve went pop.

Precautions for safe handling
1. Wash thoroughly after handling.
2. Use only in well ventilated area.
3. Ground and bond containers when transferring.
4. Use spark-free tools and explosion proof equipment.
5. Empty containers retain product residue (liquid/vapor), and can be dangerous.
6. Do not pressurize, cut, weld, braze, solder, drill, or expose empty containers to heat, sparks or open flames.
Conditions for safe storage, including any incompatibilities
1. An inhibitor is added to the monomer for protection during shipment and subsequent storage. The monomer must be
checked at regular intervals to determine inhibitor and polymer content if the material is being stored for any period of time in excess of thirty days at 32℃(90℃). The shipper should be consulted for the methods of making these determinations and their significance. 2. Iron, galvanized iron, and steel are suitable metals for tanks. 3. Storage should be located away from any area subject to fire hazards. Storage tanks located in the open or underground minimize the danger of fire, vapor and health problems. 4. Vents and flame arrestors can be easily plugged with formation of polymer. These must be periodically inspected and 5. All openings in the system should terminate outdoors and be protected by flash screen. 6. Electrical installation should conform to the National Electrical Code. 7.Storage tanks should be electrically bonded and grounded to prevent dangerous accumulations of static electricity. (see 8. Natural ventilation is all that is needed for outdoor storage installation. 9. For indoor storage : Good natural ventilation may be sufficient. The generally considered maximum allowable concentration is 50 ppm by volume in air for an eight-hour working exposure. A concentration of 5640 ppm may be fatal in 4 hours. If other than natural ventilation is required, the ventilation equipment should be designed to handle the heavy styrene monomer vapor. Since styrene monomer vapor is heavier than air, a down draft mechanical exhaust is indicated in those operation in which general ventilation should be to ensure a substantial air flow away from the work area. All ventilating systems require periodic inspection.

Safety Data Sheets (SDS)
Engineering control
1. Process should be located at least 17 meter (50 feet) away from open flames and all high temperature operations likely
to cause ignition of the styrene monomer vapor. 2. In venting styrene monomer vapors, consideration should be given to possible halogenation of the vapors by low concentrations of free chlorine and bromine with the resultant formation of lacrimations. 3. Process should be designed so that the operator is not exposed to direct contact with styrene monomer or the vapor. The technical problems of designing equipment, providing adequate ventilation and operating procedures which promise maximum security and economy, can best be handled by competent engineers. Due to the tendency of styrene monomer to form polymers which may plug equipment, all piping, valves, gauges, vents, tank openings, pressure relief devices, and engineering controls should be so designed and located that may be readily and periodically inspected and cleaned. 4. It is essential for safety that equipment be used and maintained as recommended by the manufacturer. 5. Tanks used to store or process styrene monomer should be closed vessels vented to a safe point of discharge in the outside atmosphere away from operating stations, roadways, and at least 17 meter (50 feet) from possible sources of ignitions. All sparks, flames, heated surface, or other sources ofignition should be kept away from all vents. It is advisable, to provide suction on vessels when inspection or observation openings are made, to minimize or eliminate escape of vapors. Personal protective equipment
Personal respirators (NIOSH Approved):
If the exposure limit is exceeded, a half-face organic vapor respirator may be worn for up to ten times the exposure limit or the maximum use concentration specified by the appropriate regulatory agency or respirator supplier, whichever is lowest. A full-face piece organic vapor respirator may be worn up to 50 times the exposure limit or the maximum use concentration specified by the appropriate regulatory agency or respirator supplier, whichever is lowest. For emergencies or instances where the exposure levels are not known, use a full-face piece positive-pressure, air-supplied respirator. (Warning: Air-purifying respirators do not protect workers in oxygen-deficient atmospheres.) Wear impervious protective clothing, including boots, gloves, lab coat, apron or coveralls, as appropriate, to prevent skin contact. Use chemical safety goggles and/or a full face shield where splashing is possible. Maintain eye wash fountain and quick-drench facilities in work area.

Vapor is explosive when exposed to heat or flame; reacts with oxygen above 40℃ (104℃) to form a heat-sensitive
explosive peroxide. On exposure to light and air, styrene slowly undergoes polymerization and oxidation with formation
of peroxides. Violent polymerization may be initiated by alkali metal-graphite composites,butyllithium, dibenzoyl
peroxide, azoisobutyronitrile or di-tert-butyl peroxide. Violent reaction with chlorosulfonic acid, oleum, sulfuric acid and
