GENERAL INSTRUCTIONS

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

3oc

minimum product temperature.

Measure product temperature from the centre of every bin

pallet

assure that the

product achieves a minimum temperature of 3oc.

Pre-heat the PPO chamber

49-51°C.

Load the conditioned product into the pre-heated PPO chamber and close all doors and

vents.

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

completely sealed.

Turn

PPO vaporiser

achieve a temperature

at least 60°C, but not

excess

53c.

Inject a sufficient amount

through the vaporiser

assure that

vapour

the chamber reaches at least 0.5 kg/m3. (The absolute amount

PPO will depend

upon the chamber size.) The vacuum

the chamber will decrease slightly upon

addition of the

PPO.

Inject

inert gas to decrease chamber vacuum to between

kPa.

Treat product for 4 hours. (The pasteurisation time begins after completion

inert gas

injection.)

After 4 hours

exposure, increase the vacuum

between

kPa.

To ensure effective off-gassing, a minimum of two (2) carbon dioxide purges, followed

by a minimum

four (4) air purges must

completed. The purge cycle

purge back to

kPa (x2), followed

Vacuum

(-96

kPa); air

held under vacuum for

15-20

minutes

The number of cycles varies with chamber size and should allow air surrounding the

product being transferred from the chamber

contain

more than 5 mg/kg (12

mg/m3) PPO.

After completion of aeration cycles, transfer the product to a room for post-ventilation

treatment. The temperature recommended for post-ventilation

38-43°C for at least two

days

at ambient temperature above

15'C

for five days. A higher temperature speeds

dissipation of PPO.

Release the product after 15 days.

Record all measurements and document all recordings for each PPO pasteurisation

treatment.

Good manufacturing practices must

assure that recontamination

ofthe

treated almonds does not occur.

Individual treatment facilities must

validated and equipment calibrated

demonstrate they are

operating within the established parameters.

Operating Precautions:

Plant:

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

static

electricity (ignition source). Feed lines/pipes are to be regularly cleaned/maintained.

Personal Protective Equipment (PPE):

case

emergency sufficient PPE (full-body suit, face shields and respirators) for each operator

must be

strategically placed throughout the plant.

Placarding:

All entrances to the fumigated area must be placarded with the statement "DANGER, area under

fumigation. DO

ENTER, unless wearing appropriate personal protective equipment." The

placard should also carry the skull and crossbones pictogram.

Monitoring:

The control system must be continuously monitored to ensure that the process is maintained

under

negative pressure (between

kPa as per standard operating procedure).

The plant is

be equipped with a suitable system for monitoring air levels

propylene oxide

'high

risk' work areas (e.g. gas chromatograph with a remote automatic air sampler). Operators must

check

detector readings before entering 'high risk' areas. On-line detectors (sensors) are to have an alarm

response preset to 5 mg/kg (12 mg/m

propylene oxide. Alarms should be located around chamber

doors,

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').

Ventilation:

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

propylene oxide

below 5 mg/kg) with the vacuum pump turned

(to draw air through the chamber

before unloading into the aeration (off-gassing) room.

Aeration:

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

(-96

kPa);

purge back

10 kPa (x2), followed

Vacuum

(-96

kPa); air to atmospheric pressure (x4). Each air-wash should

be held under vacuum for

15-20

minutes

facilitate desorption

gases.

Off-Gassing:

Fumigated goods must be stored

a well-ventilated area

a temperature above

25'C

for a sufficient

period

time

ensure that propylene oxide residues/emissions are below 2 mg/kg (4.8 mg/m

before being released for off-site transportation. This area should be maintained under negative

pressure (using

extraction system) and sealed

from other areas

the plant. The seal must be

sufficiently robust to prevent leaks during power/fan failures.

Handling Precautions:

This product is an extreme fire hazard. Keep away from heat, sparks, open flame and heated

surfaces.

Drums may

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

air exhaust

indoors. If a hissing sound

heard do not further open the small

bung until the hissing sound stops. Only when the small bung

completely opened

the pressure

be considered as relieved.

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

displace the

contents with

inert gas. Care must be taken

ensure that no appreciable pressure is exerted on

the drum. A pressure relief device set

several inches of water should be installed

the inert gas

line.

not allow foreign material to get into the drum especially acidic

alkaline materials as hazardous

polymerisation may occur.

PRECAUTIONS

DO

NOT

enter the chamber, where full fumigation concentrations are present.

cases

extreme emergency, self-contained breathing apparatus (SCBA) or ambient air breathing

apparatus must

employed.

DO

NOT

open chamber door until measured levels

propylene oxide are below 5 mg/kg (12 mg/m3).

RE- HANDLING PERIOD

DO NOT

allow handling

the fumigated goods for off-site transportation until propylene oxide

residues /emissions are below 2 mg/kg

SAFETY DIRECTIONS

Can kill

inhaled or swallowed. Harmful if absorbed

skin contact. Will irritate the skin. Will damage

the eyes. Repeated exposure may cause allergic disorders.

Avoid contact with eyes and skin.

not inhale vapour.

When handling propylene oxide drums/cylinders, and when entering areas where exposure to

propylene oxide vapour above 1 ppm is likely, wear chemical resistant clothing buttoned

the neck

and wrist and washable hat, elbow-length butyl rubber gloves, impervious footwear (not steel capped)

and full-face respirator with organic vapour cartridge.

Wash hands after use. After each day's use wash gloves, goggles, respirator and

rubber wash with

detergent and warm water and contaminated clothing.

FIRST AID

poisoning occurs, contact a doctor or Poisons Information Centre. Phone Australia 13
