SECTION 4: First aid measures
Description of necessary first-aid measures
Move the victim into fresh air. If breathing is difficult, give oxygen. If not breathing, give artificial respiration and consult a doctor immediately. Do not use mouth to mouth resuscitation if the victim ingested or inhaled the chemical.
Take off contaminated clothing immediately. Wash off with soap and plenty of water. Consult a doctor.
Rinse with pure water for at least 15 minutes. Consult a doctor.
Rinse mouth with water. Do not induce vomiting. Never give anything by mouth to an unconscious person. Call a doctor or Poison Control Center immediately.
Most important symptoms/effects, acute and delayed
SYMPTOMS: Symptoms of exposure to this compound may include eye, skin, upper respiratory and mucous membrane irritation. ACUTE/CHRONIC HAZARDS: This compound is harmful by inhalation, ingestion or skin absorption. It may cause eye, skin, mucous membrane and upper respiratory tract irritation. When heated to decomposition it may emit toxic fumes of carbon monoxide and carbon dioxide. (NTP, 1992)
Indication of immediate medical attention and special treatment needed, if necessary
The bioelimination and organ retention of (14)C benzanthrone, an anthraquinone dye intermediate, were determined in rats, mice and guinea pigs. Urinary excretion of benzanthrone during 96 hours was higher in guinea pigs (28%) compared with rats and mice (19%). However, fecal elimination during 96 hours was higher in rats (39%) and mice (42%) than in guinea pigs (25%). Urinary elimination of benzanthrone in rats and mice was highest between 12 and 24 hours. The maximum amount of radiolabelled benzanthrone was eliminated through feces at 24-48 hours in all the three animal species. The retention of (14)C benzanthrone in the liver was comparable in rats (11.2%) and mice (11.9%), while in guinea pigs it was substantially higher (21.9%). The testes of rats and mice were devoid of radioactivity, whereas those of guinea pigs showed a marginal retention (1.25%) of (14)C. The present study suggests that guinea pigs are more prone to benzanthrone toxicity than are rats and mice since the bioelimination of this compound is slower and its organ retention is higher in this species.
SECTION 5: Firefighting measures
Suitable extinguishing media
Fires involving this material can be controlled with water spray, a dry chemical, carbon dioxide or Halon extinguisher. (NTP, 1992)
Specific hazards arising from the chemical
Flash point data for this chemical are not available; however, it is probably combustible. (NTP, 1992)
Special protective actions for fire-fighters
Wear self-contained breathing apparatus for firefighting if necessary.
SECTION 6: Accidental release measures
Personal precautions, protective equipment and emergency procedures
Avoid dust formation. Avoid breathing mist, gas or vapours.Avoid contacting with skin and eye. Use personal protective equipment.Wear chemical impermeable gloves. Ensure adequate ventilation.Remove all sources of ignition. Evacuate personnel to safe areas.Keep people away from and upwind of spill/leak.
Environmental precautions
Prevent further spillage or leakage if it is safe to do so. Do not let the chemical enter drains. Discharge into the environment must be avoided.
Methods and materials for containment and cleaning up
Collect and arrange disposal. Keep the chemical in suitable and closed containers for disposal. Remove all sources of ignition. Use spark-proof tools and explosion-proof equipment. Adhered or collected material should be promptly disposed of, in accordance with appropriate laws and regulations.
SECTION 7: Handling and storage
Precautions for safe handling
Handling in a well ventilated place. Wear suitable protective clothing. Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Use non-sparking tools. Prevent fire caused by electrostatic discharge steam.
Conditions for safe storage, including any incompatibilities
Store the container tightly closed in a dry, cool and well-ventilated place. Store apart from foodstuff containers or incompatible materials.
SECTION 8: Exposure controls/personal protection
Control parameters
no data available
no data available
Appropriate engineering controls
Ensure adequate ventilation. Handle in accordance with good industrial hygiene and safety practice. Set up emergency exits and the risk-elimination area.
Individual protection measures, such as personal protective equipment (PPE)
Wear tightly fitting safety goggles with side-shields conforming to EN 166(EU) or NIOSH (US).
Wear fire/flame resistant and impervious clothing. Handle with gloves. Gloves must be inspected prior to use. Wash and dry hands. The selected protective gloves have to satisfy the specifications of EU Directive 89/686/EEC and the standard EN 374 derived from it.
If the exposure limits are exceeded, irritation or other symptoms are experienced, use a full-face respirator.

Persistence and degradability
Benzanthrone at 100 ppm degraded 0% using 30 ppm sludge after 4 weeks of incubation(1). Benzanthrone was not present the first week in soil treated with diesel oil then incubated, but appeared after the second week and persisted through the ninth week(2). After the thirteenth week, no benzanthrone could be detected. The authors suggested that benzanthrone was possibly a degradation product that was subsequently also degraded.
Bioaccumulative potential
A range of experimental BCF values of 61-181 was reported for benzanthrone in carp(1). According to a recommended classification scheme(2), this BCF value suggests that bioconcentration in aquatic organisms will be an important fate process(SRC).
Mobility in soil
The Koc of benzanthrone is estimated as approximately 1.22X10+4(SRC), using an experimental log Kow of 4.81(1) and a regression-derived equation(2,SRC). According to a recommended classification scheme(3), this estimated Koc value suggests that benzanthrone is immobile in soil(SRC).
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.
