Chlorine Dioxide
Odour Bomb

Procedure

1. 1

   **SHARED PREP** — Don full PPE before any chemical handling: respirator on and seal-checked, sealed eyewear, nitrile gloves, long sleeves. Confirm gas/P2 cartridges in date.

   Hazards

   • ⚠Operator handling tablet without respirator — even tablet handling can release small ClO₂
   • •Loose-fitting respirator — seal failure

   Controls

   • ✓PPE on FIRST, before opening tablet pack — every time
   • ✓Positive/negative pressure seal-check on respirator before any chemical work
   • ✓Cartridges in date and gas-rated (not just P2) — check before use
2. 2

   **SHARED PREP** — Pre-treatment vehicle prep: confirm vehicle is empty (no people, no animals, no open food, no pressurised aerosols, no temperature-sensitive items). Remove gross debris per JSA 04. Close all windows. Turn HVAC to RECIRC if treating cabin air; FRESH if treating ducts.

   Hazards

   • ⚠Treating a vehicle with someone or an animal still inside
   • •Aerosol cans rupturing in heat
   • •HVAC setting wrong — treatment doesn't reach intended area

   Controls

   • ✓360° walk-around before sealing — every door, every footwell, boot, behind seats
   • ✓Confirm vehicle is gross-debris-free (per JSA 04) — odour treatment is the last step
   • •Note HVAC setting for the customer record
   • •Remove or check any temperature-sensitive items (chocolate, aerosols, pets' toys with batteries)
3. 3

   **SHARED PREP** — Activate the tablet. Add ~200 mL water to a clean plastic bottle (per product instructions; some products use specific containers). Drop one tablet into the water. Cap loosely or per product instructions (do NOT seal tightly — gas pressure builds).

   Hazards

   • ⚠Sealing the bottle tightly — pressure rupture
   • ⚠Splash of activated solution to skin / eyes
   • •Wrong water volume — incomplete reaction

   Controls

   • ✓Per product label — most ClO₂ tablets specify "do not seal" or use a vented cap
   • ✓Sealed eyewear and gloves on for the pour
   • •Use only the volume specified by the manufacturer (commonly ~200 mL)
   • •Solution is single-use — never store partially-activated solution
4. 4

   **METHOD A — AERATOR** — Place the bottle in the centre console / passenger footwell. Insert the aerator tube. Switch on the aerator. Confirm air bubbles are visibly passing through the solution. Set timer for 1–2 hr per the job spec.

   Hazards

   • ⚠Aerator battery dies mid-treatment — gas continues to release; treatment time becomes unpredictable
   • •Bottle tipping over inside vehicle — solution onto carpet
   • •Aerator tube falling out of the solution

   Controls

   • ✓Use a fresh / fully-charged battery EVERY time. Spare battery checked.
   • ✓If aerator fails mid-treatment: do NOT re-enter without re-donning full PPE
   • •Bottle in stable position (cup-holder if possible). Tube secured by cap.
   • •Set treatment timer + write end time on the door sign in marker
5. 5

   **METHOD B — STATIC** — Place the bottle in the centre console / passenger footwell. No aerator. Cap loosely per product instructions. Treatment runs 10–12 hr — typically scheduled overnight.

   Hazards

   • •Bottle tipping over during long unattended period
   • ⚠Vehicle accessed overnight by unauthorised person
   • •Treatment area unattended overnight — no immediate response if something goes wrong

   Controls

   • ✓Vehicle locked, doors confirmed shut, key with operator
   • ✓Door sign affixed and end time written: typically next-morning time
   • •Bottle in stable position — cup-holder or wedged in footwell
   • •Site security confirmed — gate locked, alarm armed if applicable
6. 6

   **SHARED — POST-TREATMENT** — At end of treatment time: from outside the vehicle, open one door (preferably remotely or with respirator on). Step back and let gas vent for at least 60 seconds before approaching. Then open all doors and windows.

   Hazards

   • ⚠Operator opening door without PPE on, getting a face full of accumulated ClO₂
   • •Gas drift to adjacent area as doors open

   Controls

   • ✓RE-DON full PPE before approaching the vehicle, including respirator and eyewear
   • ✓Open one door from a stride away (long-arm reach), step back, let it vent before opening more
   • •Position vehicle so prevailing wind carries vent gas AWAY from any other work area
   • •Notify any nearby workers before opening
7. 7

   **SHARED — POST-TREATMENT** — Remove the bottle. Pour residual solution into a labelled disposal container — NEVER tip onto ground or into stormwater. Dispose per SDS / wastewater system (NOT stormwater).

   Hazards

   • ⚠Residual solution to stormwater — environmental notifiable event
   • •Splash during pour

   Controls

   • ✓Dispose to wastewater (workshop trade-waste sink) ONLY — never to stormwater drain
   • ✓Sealed eyewear + gloves still on for the pour
   • •Rinse the bottle three times with water; rinse water also to wastewater
   • •Bin the empty bottle if single-use; clean and dry if reusable
8. 8

   **SHARED — POST-TREATMENT** — Ventilate the vehicle for a minimum of 2 hours with all doors and windows open before any handover. Sniff-check from outside before re-entering for any final detail work. Remove the door sign.

   Hazards

   • •Handing over a vehicle with residual ClO₂ in HVAC or upholstery
   • •Customer or next worker entering before vent time complete

   Controls

   • ✓Minimum 2-hour ventilation — set timer, do NOT skip
   • •Run HVAC on FRESH for last 15 min of vent if treating cabin air
   • •Sniff-check together with the customer at handover
   • •If any residual smell: extend ventilation, do not hand over
9. 9

   **SHARED — DOCUMENTATION** — Record method (A or B), duration, ventilation time, and result in the job notes. File any deviation or incident.

   Hazards

   • •Missed documentation — no record if a customer complaint follows

   Controls

   • •Method, duration, vent time, smell-check result captured in job notes
   • •Photo of door sign with start/end times preferred
   • •Any aerator failure / unauthorised entry / extended vent → Incident Report Form
