IDENTIFICATION OF THE PREPARATION AND COMPANY
Magtoxin tablets, Magtoxin roundtablets
Detia Degesch GmbHDr.-Werner-Freyberg-Str. 11D-69514 LaudenbachGermany COMPOSITION / INFORMATION ON HAZARDOUS INGREDIENTS
Preparation with ignition inhibiting additives Chem. Characterization / Concentration / Symbol / R-phrases / CAS-No.
Magnesium phosphide 66% F, T+, N R 15/29-28-50 CAS-No. 12057-74-8 Chem. Characterization / Concentration / TLV (Germany)Hydrogen phosphide 0.1 ml/m3 (ppm), 0.14 mg/m3 Odour threshold for hydrogen phosphide: from 0.02 up to 3 ppm depending on the sensitivity1b) POSSIBLE HAZARDS
On contact with water or acids the product develops the extremely flammable and toxic hydrogen phosphide(phosphine) FIRST AID MEASURES
Inhalation: in case of headache, dizziness, fealing of constriction, difficult breathing and nausea immediately leavethe danger zone and seek fresh air; consult a physician; inhale products for acute treatment following exposition ofsmoke gas (eg a beclometasone (Ventolair®) spray, a dexamethasone (Auxiloson®) spray). Eye contact: remove rests of preparation with fluff-free cloth; rinse with plenty of water and apply eye drops only afterno more powdery residues are visible.
Skin contact: remove any rests by brushing; only then use water for cleansing Special aids required for First Aid measures: have methylprednisolon (application by physician) and products foracute treatment following exposition of smoke gas (eg a beclometasone (Ventolair®) spray, a dexamethasone(Auxiloson®) spray) available FIRE-FIGHTING MEASURES
Suitable extinguishing media: the product itself does not burn; extinguish fires in the vicinity with dry sand or powderand than with CO Extinguishing media that must not be used for safety reasons: water, extinguishers containing water Special hazards from the substance itself, its combustion products or from its vapours: in case of fires hazardouscombustion gases are formed: caustic phosphoric acid aerosols (phosphoric pentoxide) Special protective equipment for firefighting: respiratory equipment, see No. 8.1 below ACCIDENTAL RELEASE MEASURES
Person-related precaution measures: leave danger zone immediately; see No. 8 below Environment protection measures: n.a.
Methods for cleaning up / taking up: n.a.
HANDLING AND STORAGE
Advice on safe handling: adhere to regulations for the handling of dangerous goods Demands upon storerooms and containers: see No. 7.1.1 Further information on storage conditions: Obviate contact with water, acids and ambient humidity EXPOSURE CONTROLS / PERSONAL PROTECTION
Respiratory protection: respiratory equipment suitable for hydrogen phosphide, filter B, colour grey Body protection: suitable protective clothing 9. * PHYSICAL AND CHEMICAL PROPERTIES
Form: under the influence of ambient air the solid products develop gaseous phosphine Colour: powder greyish-green; paper (Plates/Strips) orange, tyvek (Gas-Ex-B forte) white Melting point / range (in /C): magnesium phosphide > 500 /C 11) Inflammability (solid, gaseous): in contact with water/humidity, acids an extremely flammable gas is developed Selfignition: contains additives to prevent self ignition Lower explosion limit: hydrogen phosphide: 1.8 1a) (1.79-1.89) Vapour pressure: hydrogen phosphide: 34.6 bar (20/C) 9) Solubility in water: not applicable due to decomposition Distribution coefficient (n-octanol/water): n.a.
STABILITY AND REACTIVITY
Conditions to be avoided: see No. 7 above Substances to be avoided: water and acids cause magnesium phosphide to decompose in a violent reaction into extremely flammable and toxic hydrogen phosphide Hazardous decomposition products: hydrogen phosphide, phosphoric pentoxide, phosphoric acid, see No. 5.3 Change of aggregation condition:Influence on safety: uncontrolled development of hydrogen phosphide can cause fires TOXICOLOGICAL DATA
Swallowing, LD rat oral (mg/kg): magnesium phosphide: 11.2 2), Magtoxin: 9.12 3) Inhalation, LC rat inhalative (4hrs.): hydrogen phosphide: 11 ppm = 0.015 mg/l 4) Skin contact, LD rat dermal (mg/kg): n.v.
Sensitizing effect: Magphos: no skin sensitization 10) Other information: inhalation and ingestion of large quantities may lead to very serious poisoning. Highly dangerousafter 1/2 to 1 hour are already 400-600 mg/m3 =290-430 ppm phosphine 1c)IDLH (Immediately Dangerous to Life and Health) = 282 mg/m3 = 200 ppm (US EPA,1985) phosphine 5) ECOLOGICAL INFORMATION
LC (rainbow trout, 96 hrs.) = 9.7 x 10-3 ppm 6) EC (daphnia magna, 24 hrs.) = 0.2 mg/l 7) Ecotoxicity: phosphine decomposes in the atmosphere within 5 - 28 hours 8) DISPOSAL CONSIDERATIONS
For substance / preparation / residues: product: waste code #: 061301 Recommendation: degassed material should be disposed of under observation of the prevailing regulations (waste code #: 060316) TRANSPORT INFORMATION
