Do not handle until MSDS & all safety precautions have been read and understood. Use personal protective equipment as required.
Before use, carefully read the product label. Safe work practices are advised to avoid eye or skin contact and inhalation. Observe good personal hygiene, including washing hands before eating. Prohibit eating, drinking, and smoking in contaminated areas. Avoid inhalation. Mechanical extraction ventilation is recommended when the removal of atmospheric contaminants is required. Maintain dust/fume levels below the recommended exposure standard. For small amounts, absorb with sand, vermiculite or similar and dispose of at an approved landfill site.

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 before entering cabin.

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.

COMMISSIONING PROCEDURES

COMMISSIONING PROCEDURES – CABIN PRESSURE

Commissioning Procedures

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 .
