Q&A
Production Process
 Can occur in many places around premises &
elsewhere:
 Kitchen, laundry, bathroom, common rooms,
bedrooms
 Garages, sheds, backyard
 Bush blocks, vacant land, motel/hotels, vehicles
 Useful to have water, electricity, sinks/drainage,
ventilation, sealed working areas
Contamination Process
 Contamination arises from aerosol production,
spillage & waste disposal
 Spillage/waste is often obvious
 Aerosol deposition especially meth is often
inconspicuous & pervasive
 Even only a few small Nazi/birch reactions may
lead to surface contamination of well beyond
immediate area
 Meth contamination can continue for years
Range of Chemical Hazards
 Toxic gases produced that can cause death or
injury (phosphine is the most deadly)
 Flammable chemicals used in process
 Corrosive chemicals such as hydrochloric and
sulfuric acid used for extraction
 Chemicals may condense on surfaces
 Unknown hazards from meth by-products
The Nazi or Birch Reduction Method




Most common method in WA
Quick, inexpensive, simple & portable
Get everything from a hardware store
Utilises caustic soda, sulphate of ammonia, LPG,
solvents, lithium metal
 Generates anhydrous ammonia, hydrogen chloride
gas, toxic reaction waste
 30 minute process
Human Exposure
 Mainly concerned about house occupants, or
frequent visitors
 Toddlers particularly vulnerable due to hand-mouth
activity, ongoing presence & physiology
 Also other children, pregnant women, & infirm
 Exposure thru dust gas inhalation & inadvertent
ingestion
 Usually long term exposure the problem tho
occasionally acute eg operator burns, deaths

Trip hazards
Needles

Animals
Operators
Environmental Hazards
 Can be in backyard, vacant land, bush areas
 May be surface but leaching into soil, septics &
groundwater possible
 May affect environment or people directly tho
usually a lesser concern than residential
