appropriate action
    12. What are the conclusions about risk? Only answer 'Yes' to one conclusion.
        *               Conclusion 1:   Risks are not significant
        *               Conclusion 2:   Risks are significant but effectively controlled
     If you answer Yes to conclusion 1 or 2, go to Q.14.
        *               Conclusion 3:   Risks are significant and not adequately controlled
        *               Conclusion 4:   Uncertain about risks
     If you answer 'Yes' to conclusion 3 or 4, go to Q.13.
    13. Have actions resulting from conclusion about risks been identified?
        *               Seek expert advice
        *               Requires appropriate control measure
        *               Requires induction training
        *               Requires on-going monitoring
        *               Requires health monitoring
        *               Requires emergency procedures and first aid
    14.   Has the assessment been recorded?                                                                                                                                 □    □

APPENDIX H – EXAMPLES OF COMMON FUEL AND OXYGEN SOURCES

Fuel type                          Examples*                                                                                                                                                                                                                                                                               Label elements

Flammable gases                    liquefied petroleum gas (LPG), natural gas, hydrogen, acetylene, hydrogen sulphide, carbon monoxide
Flammable and combustible liquids  petrol, mineral turpentine, lighter fluid or 'shellite', kerosene, methylated spirit, acetone, ether, ethanol, hexane, pentane, naphtha, some solvent based paints, diesel, including biodiesel, petroleum based oils, some oil based paints, cotton seed, linseed and eucalyptus oils  (flammable liquids categories 1-3 only).
Flammable and combustible solids   bitumen, asphalt, fats and greases, waxes, shellac, acetate and nitrocellulose films, timber and timber products, paper, cardboard, dry grasses, hay, straw, plastics, silk, granulated rubber, metal shavings, filings                                                                 (flammable solids only)
Other fire risk chemicals**        Pyrophoric substances like some barium and calcium alloys, iron sulphide and celluloid scrap
Dusts                              Any dusts that can are generated through other processes, such as metal grinding, filling, etc                                                                                                                                                                                          none
Chemical reactions***              Water reactive chemicals like calcium carbide, sodium hydride, and some aluminium, lithium, magnesium or zinc powders (which liberate flammable gases like hydrogen on contact with water or acids).

Notes:
* The form of the substance or material can significantly affect the risk.  In general, the smaller the particle size the greater the risk.  For example, fine shavings or powders of metals present a much greater risk than metals in the bulk or massive form.
** Pyrophoric substances can react spontaneously in contact with air.
*** Chemical reactions which generate gases can also cause explosions through an increase in the pressure in the container in which the chemical is stored if the gas cannot escape, even if that gas does not itself ignite.
 Examples of oxygen sources                                                                                                                                                                     Label elements

Oxygen and air cylinders in welding equipment, hospitals for treatment of patients, reticulated gas supplies in a laboratory, air tanks in self contained breathing apparatus (SCBA) equipment
Nitric acid, nitrates, nitrous oxide, sodium hypochlorite, chlorates, perchlorates, hydrogen peroxide and organic peroxides, potassium permanganate

Note: Oxygen gas is always present in the air so you should assume that it is present
