Rinse mouth. Refer for medical attention .
Most important symptoms/effects, acute and delayed
Excerpt from ERG Guide 171 [Substances (Low to Moderate Hazard)]: Inhalation of material may be harmful. Contact may cause burns to skin and eyes. Inhalation of Asbestos dust may have a damaging effect on the lungs. Fire may produce irritating, corrosive and/or toxic gases. Some liquids produce vapors that may cause dizziness or suffocation. Runoff from fire control may cause pollution. (ERG, 2016)
Indication of immediate medical attention and special treatment needed, if necessary
Immediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand-valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR as necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention. Aromatic hydrocarbons and related compounds

Persistence and degradability
Chlorinated benzenes (including pentachlorobenzene) were stable under both aerobic and anaerobic conditions. (36)C-labeled chlorinated hydrocarbons were prepared and incubated with mixed microbial cultures obtained aerobically or anaerobically from arable soil or sewage sludge. Pentachlorobenzene showed slight dechlorination (3-4%) during anaerobic incubation with Clostridia and with aerobic Pseudomonas species.
Bioaccumulative potential
BCF values of 1,400 to 6,800 were measured in carp exposed to 10 ug/L of pentachlorobenzene during an 8 week incubation period and BCF values of 1,100 to 5,100 were measured in carp exposed to 1 ug/L of pentachlorobenzene during an 8 week incubation period(1). BCF values in trout were reported as 13,000-20,000(2). An experimental pentachlorobenzene BCF of approximately 5,000 was reported (fish species not reported)(3). An experimental BCF of 4790 was reported for guppy(4). In 56-day exposure studies using carp, pentachlorobenzene BCFs ranged from 4967 to 5656 in the presence or absence of various dispersants(5). In 10-day exposure studies using fathead minnow (Pimephales promelas), pentachlorobenzene BCFs ranged from 1085 to 1773(6). According to a classification scheme(7), these BCF values suggest that bioconcentration in aquatic organisms is very high, provided the compound is not metabolized by the organism(SRC).
Mobility in soil
Pentachlorobenzene has measured log Koc value of 3.5 (Koc of 3162) reported for soils(1). A log Koc value of 5.1 (Koc of 1.26X10+5) was reported for pentachlorobenzene in a freshwater river sediment(2). A log Koc value of 4.6 (Koc of 3.98X10+4) was reported for pentachlorobenzene in sediment obtained from the Ise Bay, Japan(3). A Koc of 4.0X10+4 was determined for adsorption on to whole bottom sediments from a stream(4). Log Koc values of 6.72 and 6.25 (Koc values of 5.24X10+6 and 1.78X10+6) were determined for two sediment layers from a lake(5). Pentachlorobenzene was found to desorb very slowly from sediment in water(6). According to a classification scheme(2), these measured Koc values suggest that pentachlorobenzene is expected to have slight to no mobility in soil.
Other adverse effects
no data available
SECTION 13: Disposal considerations
Disposal methods
The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.
Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
