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.

Personal Protective Equipment (PPE)
Safety glasses must be worn at all times. Sturdy footwear with rubber soles must be worn. Respiratory protection devices may be required. Gloves may be worn.

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.

Pre-operational Safety Checks
Locate and ensure you are familiar with all machine operations and controls. Check work area and walkways to ensure no slip/trip hazards are present. Ensure the work area is clean and clear of any flammable material & fire extinguish device is present.
Operational Safety Checks
Ensure the machine is correctly isolated / immobilized. Ensure other persons do not inhale smoke haze. Take care and do not place a lit emitter close to a flammable surface.
Ending Operations and Cleaning Up
Leave the work area in a safe, clean, and tidy state.

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.

Falls Fumes Fire

Potential Hazards

May cause cancer
Exposure is highly unlikely when the product is used as directed. Direct contact with the product does not occur.

Don’t
Do not use if an open flame is forbidden.
Never leave the emitter [cabin test] unattended.

*This SWP does not necessarily cover all possible hazards associated with this equipment and should be used in conjunction with other references. It is designed as a guide to be used to compliment training and

as a reminder to users prior to equipment use.

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; you must ensure that cabin seals are adequate for maintaining positive pressure. In addition, the site (end- user) must have the correct procedure(s) for servicing OPERATOR enclosure seals in a proactive manner rather than reactive. 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:

“System Check”

Proceed to online commissioning:
