Most important symptoms and effects, both acute and delayed

Excerpt from ERG Guide 133 [Flammable Solids]: Fire may produce irritating and/or toxic gases. Contact may cause burns to skin and eyes. Contact with molten substance may cause severe burns to skin and eyes. Runoff from fire control may cause pollution. (ERG, 2016)

Within 5 to 90 minutes after swallowing, the following may be noted: nausea and vomiting; feeling of warmth; headache; confusion, vertigo, excitement, restlessness, delirium, and hallucinations; increased muscular excitability, tremors, and jerky movements; epileptiform convulsions, followed by depression (convulsions sometimes occur early in the syndrome and may be severe, but they do not have the grave prognosis of strychnine convulsions); coma; central nervous depression may at times be the primary clinical response; death results from respiratory failure or from status epilepticus; slow convalescence (days or weeks), often with persistent gastric distress. (USCG, 1999)

SYMPTOMS: Ingestion of this compound may cause nausea, vomiting, vertigo, mental confusion, delirium, convulsions, coma, respiratory failure or death. It may also cause a burning sensation, coughing, wheezing, laryngitis, shortness of breath, headache, severe irritation and possible destruction to the tissues of the mucous membranes, upper respiratory tract, eyes and skin. Other symptoms may include congestion and edematous changes in the gastrointestinal tract, kidneys and brain. Ingestion may result in burning in the mouth and throat, epigastric pain, thirst, feeling of tension, dizziness, irrational behavior, unconsciousness, rigidity, rapid pulse, slow respiration, twitching of the facial muscles and muscular spasms. Other symptoms may include flickering, darkening or veiling of vision, noises in the ears and weakness. Exposure to this compound may also result in a feeling of warmth, depression of the central nervous system, difficult breathing, a characteristic breath odor and anuria. Colic may also be a symptom of exposure. Other symptoms may include eye irritation, sore throat, excitement, fever, bluish lips, pale face, loss of sense of smell and agitation. ACUTE/CHRONIC HAZARDS: When heated to decomposition this compound emits toxic fumes of carbon monoxide and carbon dioxide. It is harmful if swallowed, inhaled or absorbed through the skin. It can be absorbed through mucous membranes. (NTP, 1992)

Indication of any immediate medical attention and special treatment needed

Treatment of camphor intoxication is primarily supportive with a focus on airway management and seizure control. No antidotes are available. Activated charcoal should be administered for gastrointestinal decontamination, although its efficacy is doubtful. Due to prominent CNS effects, the induction of emesis is contraindicated. If liquid camphor is ingested, a nasogastric tube can be used to aspirate gastric contents before instillation of activated charcoal. Alcohols and oil solutions should be avoided because they have been reported to enhance absorption of camphor. Although not readily available, lipid hemodialysis and resin hemoperfusion have been reported to lower blood camphor concentrations in severely poisoned patients. Benzodiazepines such as lorazepam or diazepam are indicated for symptoms of CNS hyperactivity, such as agitation, tremors, and seizures. Phenobarbital can be used for recurrent or prolonged seizures.

SECTION 5: Firefighting measures

Extinguishing media

To fight fire, use foam, carbon dioxide, dry chemical

Specific Hazards Arising from the Chemical

Excerpt from ERG Guide 133 [Flammable Solids]: Flammable/combustible material. May be ignited by friction, heat, sparks or flames. Some may burn rapidly with flare-burning effect. Powders, dusts, shavings, borings, turnings or cuttings may explode or burn with explosive violence. Substance may be transported in a molten form at a temperature that may be above its flash point. May re-ignite after fire is extinguished. (ERG, 2016)

Behavior in Fire: The solid often evaporates without first melting. (USCG, 1999)

This chemical is flammable. (NTP, 1992)

Advice for firefighters

Wear self-contained breathing apparatus for firefighting if necessary.

NFPA 704

FIRE 2 Must be moderately heated or exposed to relatively high ambient temperature before ignition can occur and multiple finely divided suspended solids that do not require heating before ignition can occur. Flash point between 37.8 and 93.3 °C (100 and 200 °F). (e.g. diesel fuel, sulfur)
REACT 0 Normally stable, even under fire exposure conditions, and is not reactive with water (e.g. helium,N2)

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

Personal protection: filter respirator for organic gases and particulates adapted to the airborne concentration of the substance. Ventilation. Remove all ignition sources. Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting.

Methods and materials for containment and cleaning up

Methods and materials for containment and cleaning up: sweep up and shovel. Contain spillage, and then collect with an electrically protected vacuum cleaner or by wet-brushing and place in container for disposal according to local regulation... Keep in suitable, closed containers for disposal...

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

Persistence and degradability

AEROBIC: Camphor, at an influent concentration of 4.08 mg/L, was degraded to below detection limits (not specified) during a 20 hour aeration period in an aerobic activated sludge system(1). Camphor did not concentrate in the activated sludge solids. However, the loss of camphor in this process cannot be definitely attributed to biodegradation since there may have been loss due to volatilization(1). Monoterpine ketones were more resistant to biodegradation in aerated lagoon samples than monoterpine hydrocarbons or alcohols(2). The concentration of camphor actually increased in some of the samples which suggests that camphor was being produced in the lagoon. Camphor was on the list of very difficult to biodegrade compounds in a study of organic chemicals found in effluents(3). Camphor, present at 100 mg/L, reached 94% of its theoretical BOD in 4 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test which classified the compound as readily biodegradable(4).

Bioaccumulative potential

An estimated BCF of 17 was calculated in fish for camphor(SRC), using a measured log Kow of 2.38(1) and a regression-derived equation(2). According to a classification scheme(2), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).

Mobility in soil

Using a structure estimation method based on molecular connectivity indices(1), the Koc of camphor can be estimated to be 117(SRC). According to a classification scheme(2), this estimated Koc value suggests that camphor is expected to have high 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.

Contaminated packaging

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.
