Safety

WARNING

The pressurisation system described in this manual has areas that may be dangerous if not treated with great care.

Qualified staff must wear correct personal protective equipment (PPE) when cleaning and servicing the unit due to dust and fibres that may be caught by air filtration stages during normal operation.

The electrical power system is supplied by 12V DC or 24V DC. No work should be carried out on the pressuriser system without correct safe work procedures, electrical safety measures, and relevant circuit breakers opened to isolate the circuit.

The air filtration system may contain high-speed rotating equipment with sharp edges. Ensure all safety guards are in place while the system is running.

Note: HEPA filters cannot be cleaned and must be replaced at the end of their lifecycle or if filter media is damaged.

Particulate Behaviour

This section illustrates the time it takes for particles of different sizes to drop from a height of 1.5m in still air:

• 20μm (3.6 mins)
• 10μm (8.3 mins)
• 5μm (35.7 mins)
• 2μm (2.8 hrs)
• 1μm (12 hrs)
• 0.5μm (41.7 hrs)

Diagram Description: A series of coloured spheres representing particles of decreasing size, with the time taken to fall 1.5m indicated below each.

Warehouses and workshops do not have still air, so hazardous airborne particulates may remain suspended longer, increasing the chance for workers to breathe them in. Ensure PPE is worn when installing this system.

WARNING

For Professional Use Only - keep out of reach of children. Do not ignite near or around flammable materials. Use only in well-ventilated areas, outdoors, and/or with proper respiratory protection. Persons with respiratory sensitivity should avoid exposure to any smoke. Concentrated smoke may cause severe burns to the skin, eyes, or respiratory system. Improper use may result in sufficient inhalation of smoke to cause respiratory tract irritation and lung damage. Harmful if swallowed.

DANGER

Use only as directed. Do not handle until all safety precautions, including Safety Data Sheet, have been read and understood. The product contains hexachloroethane. Wear protective clothing. If exposed or concerned, get medical advice. Store in a cool, dry, secure location. KEEP OUT OF REACH OF CHILDREN. Dispose of contents/container per location regulations. When used as directed, exposure should be limited and usually poses no hazard because the hexachloroethane is consumed inside the tube as smoke is produced.

Directions: (Smoke Bomb)

1. Ensure other workers in close proximity are informed of use. Place on a non-combustible container, away from flammable materials.
2. Place at Blower intake, or upwind of target area, or near centre of space.
3. Orient "Smoke Issues Here" toward air stream, away from surfaces. Place candle on a flame / heat resistance plate - if not it will melt into the plastic surface.
4. Ensure smoke will not create any hazard where it is anticipated to go.
5. Ignite emitter inside the cabin using site approved device i.e., solder torch or 'lighter' and conduct smoke test.
6. Do not touch or hold smoke generator after ignition - item becomes very hot & remains hot after use.

Smoke Emitter Cabin Pressure Leak Test

1. The pressuriser system is switched on (TEST MODE).
2. Hold the smoke emitter angled down.
3. Ignite emitter using site approved ignitor i.e., solder torch or 'lighter'.
4. When the product ignites, remove the lighter.
5. If the product flames up, blow out the flame.
6. Place the emitter in a non-flammable container and place it inside the cabin at floor level and close the door/windows.
7. Observe smoke leaks to indicate worn-out or broken seal locations. Check leakage points outside the cabin.
8. Do not come into contact with or inhale smoke haze.
9. Wait until the smoke haze completely disperses before re-entering the cabin. Open door to allow sufficient ventilation of smoke prior to entering cabin.

Cabin Sealing Test Procedure

Cabin Sealing Efficiency Test Procedure

1. Start Engine - Pressuriser System is ON
2. Ensure all windows & door(s) are CLOSED correctly (no cabin pressure leaks). NOTE: For a new cabin with effective seals, you may need to open a window slightly before closing the door to bleed the static cabin air pressure outwards. Once door is fully closed then close windows to begin testing.
3. Enter the Settings menu via the touch screen button.
4. Select and press the System Check button to go to System Test – Max Fan.
5. Record / photograph the maximum cabin pressure achieved.

Diagram Description: Two screenshots of the INPRESS TS display. The first shows 'BACK', 'Settings', 'Cabin Pressure: 50 Pa', 'CO2 Concentration: 561 ppm', and buttons for 'SYSTEM CHECK SET MAX', 'VIEW GRAPH', 'EVENT LOG', 'SITE ACCESS MENU'. The second shows 'System Test - Max Fan', 'Cabin Pressure: 425 Pascals'. Instructions indicate to 'Press Settings' and then 'Press "System Check – Set Max" box' and 'Record / Photograph the cabin pressure result (Max Fan Speed)'.

Commissioning Procedures

COMMISSIONING PROCEDURES – CABIN PRESSURISER

Follow each step of the installation guide that was supplied with the BreatheSafe kit. Cabin sealing is an integral part of RS20 & ISO 23875; ensure cabin seals are adequate for maintaining positive pressure. The site (end- user) must have correct procedures for servicing OPERATOR enclosure seals proactively rather than reactively. Items such as door and window seals must be in good working order or new seals FITTED before the BreatheSafe system installation.

Touch-screen cabin pressure display/controller Part# 200027:

*System Check Function: enter the Settings menu option and select "System Check - Set Max." The minimum BreatheSafe requirement for cabin sealing efficiency is 250 pascals; if this result is not met, it is essential to re-examine and find pressure leaks of the enclosure and apply new sealing measures.

Submission for commissioning procedure as per the diagram below:

Diagram Description: A flowchart showing the commissioning submission process. It starts with 'Kit Installed', then 'Cabin Display Enter: "System Check"'. A decision point asks 'Does enclosure exceed 250?'. If 'Yes', it leads to 'Record & photograph results' and then 'Proceed to online commissioning: Commissioning - BreatheSafe (breathe-safe.com.au)'. If 'No', it leads to 'Further enclosure sealing required.'

The commissioning images required are:

• ID plate / Machine Serial Number / Asset Number or Call Sign
• INPRESS TL Pressuriser location
• HEPA Return Air Filter Location Option: Powered Return Air Filter
