HAZARD DATA - READ THIS BEFORE GOING ANY FURTHER!!!!

LITHIUM ALUMINIUM HYDRIDE:
CONTACT WITH WATER LIBERATES EXTREMELY FLAMMABLE GASES

A white microcrystalline powder and lumps; decomposes above 125ºC; reacts rapidly with water with evolution of hydrogen. Prevent skin, eye and clothing contact.

Toxic effects:Reaction with water produces LiOH which is corrosive to skin and eyes. Fire hazard:Arises from contact with small quantities of water. Extinguish with sand, notCO₂. Hazardous reactions:May ignite when ground with a pestle. Reacts vigorously on solution if solvents not
rigorously dried.See special warningbelow.
Spillage disposal:Clear area, shut off all sources of ignition. Wear face shield goggles and gloves. If
contained, destroy cautiously with isopropanol. If scattered, cover with solid sodium
carbonate, shovel into buckets and remove to safe place for destruction with
isopropanol.

CINNAMALDEHYDE:
HARMFUL BY INGESTION, INHALATION, AND SKIN CONTACT

Colourless/ pale yellow liquid with characterisitic odour; b.p. 125ºC (11 mmHg), m.p. -4ºC.

Toxic effects:Harmful by ingestion and inhalation. Harmful by skin contact Hazardous reactions:May react with oxidising agents
Spillage disposal:Clear area, shut off all sources of ignition. Wear face shield goggles and gloves.
Absorb onto sand and place in container for disposal

TETRAHYDROFURAN:
IRRITATING TO EYES AND RESPIRATORY TRACT
MAY FORM EXPLOSIVE PEROXIDES
HIGHLY FLAMMABLE
Colourless volatile liquid with ethereal odour; b.p. 66ºC; miscible with water. Liable to form explosive peroxides on exposure to light/air. Peroxides removed by treatment with aqueous sodium metabisulfite. Avoid breathing vapour, eye and skin contact. OEL 295 mgm^-3.

Toxic effects:The vapour irritates eyes and respiratory system; high concentrations have narcotic
effect. Absorption or ingestion may cause liver damage.
Hazardous reactions:Explosive peroxides formed on exposure to air/light. NaOH/KOH can cause explosion
with peroxided material.
Fire hazard:Flash point -17ºC; ignition temp. 321ºC; extinguish fire with CO₂. Spillage & disposal:Clear area, shut off all sources of ignition. Wear goggles, gloves, and laboratory coat.
Mop up with plenty of water and run to waste. Organise effective ventilation and
evaporate remaining liquid.
