1,3-xylene;p-xylene

5. Environmental standards :
China (TJ36-79) Workshop harmful substances in the air that the maximum allowable concentration 100mg/m3 (xylene)
China (TJ36-79) Residential District of harmful substances in the atmosphere qualitative 0.30mg/m3 maximum allowable concentration (one value, xylene)
Chinese (GB16297-1996) Air Pollutant Discharge Standards (xylene) ?maximum allowable emission concentrations (mg/m3) : ?maximum allowable emission rate (kg / h) : 1.0
2 ~ 10 (Table 2); 1.2 ~ 12 (Table 1)
~ 15 3 1.5 (Table 2); 1.8 to 18 (Table 1)
?unorganized emissions monitoring the concentration limits :
1.2mg/m3 (Table 2); 1. 5mg/m3 (Table 1)
China (to be issued), the source of drinking water of harmful substances in the maximum allowable concentration of 0.5 mg / L (xylene)
China (GHZB1-1999), surface water quality standard (I , II, Class III waters of particular value) 0.5 mg / L (xylene)
China (GB8978-1996) sewage discharge standard one : 0.4mg/L
2 : 0.6mg/L
3 : 1.0 mg / L



6. Emergency treatment and disposal methods :
a leakage contingency


rapid withdrawal from air leakage personnel to a safe area, and isolation and strict restrictions on access. Cut off the fire source. Recommended emergency personnel wearing respirators-positive pressure self-sufficiency, wearing fire protective clothing. As far as possible, cut off the source of leakage, prevent access to sewers, flood discharge trench so restrictive space. A small leak : activated carbon or other inert materials to absorb. We could also use non-flammable dispersant made of latex, wash, lotion diluted Add to the wastewater system. Large leak : to build a causeway or trenching asylum; Foam coverage, inhibiting evaporation. Ex pump used to transfer tankers or exclusive collector, recycling or shipped to the disposal of waste disposal sites. Rapid will be xylene contaminated soil collected and transferred to safe areas. Right pollution zone along the ground to enhance the ventilation and evaporation residue, remove steam. Rapid dam, cutting off water body pollution by the movement, and limitations of the fence surface xylene proliferation.


two protective measures


respiratory protection : higher concentration in air, filtered wearing gas masks (half-mask). Emergency rescue or evacuation, it is recommended to wear air respirators.
eye protection : Wear protective chemical safety glasses.
physical protection : wear protective overalls on infiltration.
hand protection : Wear rubber gloves.
other : work site prohibit smoking, eating and drinking. Work to complete, take a shower. Pay attention to personal hygiene.


three, and emergency measures


contact with the skin : stripped of contaminated clothing, use soap and water thoroughly washed skin.
eye contact : Did eyelid, mobile or saline irrigation water. Medical treatment.
Inhalation : rapidly from the scene to fresh air. To keep the airway patency. If breathing is difficult, give oxygen. If breathing stop immediately mouth. Medical treatment. Fresh into
: drink enough water, the symptoms. Medical treatment.


fire fighting methods : water cooling containers, if possible to move containers from the scene empty Department. . Extinguishant : foam, carbon dioxide, dry, sandy soil.
