EMERGENCY PROCEDURES
MINOR SPILLS
Remove all ignition sources.
Clean up all spills immediately.
Avoid contact with skin and eyes.
Control personal contact by using protective equipment.
Use dry clean up procedures and avoid generating dust.
Place in a suitable,labelled container fOr waste disposal.
Environmental hazard - contain spillage.
MAJOR SPILLS
Moderate hazard.
CAUTION: Advise personnel in area.
Alert Emergency Services and tell them location and nature of hazard.
Control personal contact by wearing protective clothing.
Prevent, by any means available, spillage from entering drains or waler courses.
Recover product wherever possible.

AlWAYS: Wash area down with large amounts of water and prevent runoff into drains.
If contamination of drains or waterways occurs, advise Emergency Services.
PROTECTIVE ACTIONS FOR SPILL
FOOTNOTES
PROTECTIVE ACTION ZONE is defined as the area in which people are at risk of harmful exposure. This zone assumes that random changes in wind direction confines the vapour plume to an area within degrees on either side of the predominant wind direction, resulting in a crosswind protective action distance equal to the downwind protective action distance.
PROTECTIVE ACTION should be initiated to the extent possible, beginning with those closest to the spill and working away from the site in the downwind direction, Within the protective action zone a level of vapour concentration may exist resulting in nearly all unprotected persons becoming incapaciated and unable to take protective action and/or incurring serious of irreversible health effects.
INITIAL ISOLATION ZONE is determined as an area, including upwind of the incident, within which a high probability of localised wind reversal may expose nearly all persons without appropriate protection to life-threatening concentrations of the material.
SMALL SPILLS involve a leaking package of litres (55 US gallons) or less, such as a drum (jerrican or box with inner containers). Larger packages leaking less than 200 litres and compressed gas leaking from a small cylinder are also considered "small spills". LARGE SPILLS involve many small leaking packages or a leaking package of greater than 200 litres, such as a cargo tank, portable tank or a "one-tonne" compressed gas cylinder.
