Specific hazards arising from the chemical
Excerpt from ERG Guide 128 [Flammable Liquids (Water-Immiscible)]: HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. Those substances designated with a (P) may polymerize explosively when heated or involved in a fire. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water. Substance may be transported hot. For hybrid vehicles, ERG Guide 147 (lithium ion batteries) or ERG Guide 138 (sodium batteries) should also be consulted. If molten aluminum is involved, refer to ERG Guide 169. (ERG, 2016)
Special protective actions for fire-fighters
Use water spray, powder, foam, carbon dioxide. In case of fire: keep drums, etc., cool by spraying with water.

SECTION 10: Stability and reactivity
Reactivity
The substance can form explosive peroxides. Decomposes on heating. This produces irritating fumes. Reacts vigorously with oxidants.
Chemical stability
Prolonged, intimate contact with air may cause the formation of tetralin peroxide; volatile with steam
Possibility of hazardous reactions
MODERATE, WHEN EXPOSED TO HEAT OR FLAME; CAN REACT WITH OXIDIZING MATERIALS. SPONTANEOUS HEATING: NO.As a result of flow, agitation, etc., electrostatic charges can be generated.TETRAHYDRONAPHTHALENE may react vigorously with strong oxidizing agents. May react exothermically with reducing agents to release hydrogen gas. Oxidizes readily in air to form unstable peroxides that may explode spontaneously [Bretherick 1979 p.151-154].
Conditions to avoid
no data available
Incompatible materials
Prolonged, close contact with air may cause an explosion.
Hazardous decomposition products
Under ... pyrolysis at 700 deg c, tetralin ... yields tars that contain appreciable quantities of 3,4-benzopyrene.

Repeated or prolonged contact with skin may cause dermatitis. The substance may have effects on the kidneys.
Aspiration hazard
A harmful contamination of the air will not or will only very slowly be reached on evaporation of this substance at 20°C; on spraying or dispersing, however, much faster.
SECTION 12: Ecological information
Toxicity
- Toxicity to fish: LC50 - Danio rerio (previous name: Brachydanio rerio) - 3.2 mg/L - 96 h.
- Toxicity to daphnia and other aquatic invertebrates: EC50 - Daphnia magna - 9.5 mg/L - 48 h.
- Toxicity to algae: EC50 - Desmodesmus subspicatus (previous name: Scenedesmus subspicatus) - 7 mg/L - 72 h.
- Toxicity to microorganisms: EC10 - Pseudomonas putida - 16 mg/L - 5 h.
Persistence and degradability
Degradation in sea water by oil oxidizing microorganisms: 31% breakdown after 21 days at 22 deg c in stoppered bottles containing a 1000 ppm mixtures of alkanes, cycloalkanes, and aromatics.
Bioaccumulative potential
A measured BCF in fish was reported to be about 200(1); this experimental BCF suggests that bioconcentration in aquatic organisms will be important environmentally(SRC).
Mobility in soil
A Koc for tetralin of about 1,800 can be estimated using a structure activity relationship(1). Based on a suggested classification scheme(2), this Koc value suggests that tetralin has low 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.
