SMOKE EMITTER CABIN PRESSURE LEAK TEST
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 pressurizer 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.
*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 – CABIN PRESSURISER
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 Breath Safe 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 Breath Safe 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:
The commissioning images required are
- ID plate / Machine Serial Number / Asset Number or Call Sign
- INPRESS TL Pressurizer location
- HEPA Return Air Filter Location Option: Powered Return Air Filter
