Standard Operating Procedure
Pasteurisation Using Propylene Oxide:
Pre-warm product to at least 30°C at the coldest point
the container. The product
temperature should not exceed 40°C during this step due to product quality concerns.
The pre-warm temperature area can
the range of 38 - 49°C to achieve the
minimum product temperature.
Measure product temperature from the centre of every bin
assure that the
product achieves a minimum temperature of 3oc.
Pre-heat the PPO chamber
Load the conditioned product into the pre-heated PPO chamber and close all doors and
Maintain a chamber temperature of 49-51°C throughout.
Apply a vacuum until the chamber reaches a minimum
kPa. Check that vacuum
holds steady to ensure that the chamber
achieve a temperature
at least 60°C, but not
Inject a sufficient amount

upon the chamber size.) The vacuum

Release the product after 15 days.
Record all measurements and document all recordings for each PPO pasteurisation
Good manufacturing practices must
assure that recontamination

38-43°C for 2 days
This procedure is only applicable for pasteurisation
Individual treatment facilities must

operating within the established parameters.
Progas should only be used
fumigation chambers fitted with scrubbers and mist eliminators to
ensure environmental release
the exhaust gas is negligible.
All equipment including feed drums is to be earthed as a precaution against build
electricity (ignition source). Feed lines/pipes are to be regularly cleaned/maintained.
Personal Protective Equipment (PPE):
emergency sufficient PPE (full-body suit, face shields and respirators) for each operator
strategically placed throughout the plant.
All entrances to the fumigated area must be placarded with the statement "DANGER, area under
ENTER, unless wearing appropriate personal protective equipment." The
placard should also carry the skull and crossbones pictogram.
The control system must be continuously monitored to ensure that the process is maintained

kPa as per standard operating procedure).
The plant is

the off-gassing room,
the storage room and
the control room. Should alarms
triggered, the working area should be evacuated until airborne levels
propylene oxide are below 2
mg/kg (4.8 mg/m'). Workers may re-enter the area provided they are equipped with the PPE specified
above until airborne levels are below 2 mg/kg (4.8 mg/m').
Mechanical ventilation to an external exhaust system is to be installed
all potential leak areas with a
scavenger air extractor system set up at floor level under the chamber doors. Backup extraction
systems must also be installed. The chamber must have an automated door locking system to
prevent manual opening
the chamber at levels
propylene oxide higher than 5 mg/kg (12 mg/m3).
Alternatively, the PPE described above must be worn when the chamber is opened.
Following purging, the chamber door should be opened (only where chamber concentration
below 5 mg/kg) with the vacuum pump turned
(to draw air through the chamber
before unloading into the aeration (off-gassing) room.
Following treatment the chamber should be evacuated through
acid scrubber and mist eliminator.
To ensure effective off-gassing, a minimum
two (2) carbon dioxide purges, followed by a minimum
four (4) air purges must be completed. The purge cycle is: Vacuum

This product is an extreme fire hazard. Keep away from heat, sparks, open flame and heated
under pressure when opened. Relieve pressure by slowly opening the small bung in a
safe, well ventilated area, standing upwind
outdoors and with the drum between the operator and
the nearest point
indoors. If a hissing sound
heard do not further open the small
bung until the hissing sound stops. Only when the small bung

When emptying drums, first electrically ground the drum. The best procedure is

the drum. A pressure relief device set
