The following are personal protective measures when using sodium hypochlorite spray guns:
1、 Basic protection four piece set
Rubber gloves
Thickened gloves (not suitable for household dishwashing gloves) must be used, with the sleeves wrapped around the outer sleeves to prevent the wrists from getting into the solution.
goggles
Anti fog full surround design, ordinary glasses have gaps, and fog can easily burn the eyes.
Splash proof mask
Ordinary medical masks are not suitable and cup type masks that require protection against liquid splashes (such as spray painted models) are needed.
Apron or hood
Choose waterproof material (PE or PVC) with a length over the knee. Cotton aprons will continue to come into contact with the skin after absorbing liquid.
2、 Additional protection for special scenarios
Work in confined spaces (such as bathrooms/storage rooms)
Upgrade to a full face gas mask with a filter box (labeled with chlorine gas prevention model), ordinary masks cannot prevent chlorine gas from evaporating.
High intensity disinfection in food workshops and other areas
Wear rubber boots: prevent solution dripping from corroding the shoe upper and seeping into the foot surface.
Wear a simple splash proof hat: to prevent hair from fading and breaking due to contact with bleach.
3、 Life saving details during operation
Taboos on holding the spray gun
Do not attempt to spray the gun towards yourself or others. Before starting the spray, empty spray away from the direction of the person.
Immediate treatment for accidental skin contact
If the solution splashes onto the skin: directly rinse with plenty of water for 10 minutes, do not wipe first (expand the contact surface).
Ventilation iron law
Even in winter, it is necessary to open windows and exhaust fans while standing at the upwind position.
4、 Don't slack off in post disaster protection
Take off the apron, rubber boots, gloves, goggles, and mask first, and wash your hands immediately after each step.
Equipment to remove residues
Rubber gloves and goggles should be rinsed with clean water and dried, and should not be exposed to sunlight (aging cracks).
Soak the cover in clean water for 10 minutes and then wash it normally.
| Protection Category | Essential Gear & Practices |
| 1. Core Protection | • Thick rubber gloves: Elbow-length preferred; sleeve cuffs must cover jacket wrists. • Sealed goggles: Full-seal anti-fog type (regular glasses leak). • Splash-proof respirator: Cup-style mask (like paint spray masks); surgical masks fail. • Waterproof apron: PVC/PE material covering knees (cotton absorbs liquid). |
| 2. High-Risk Scenes | • Enclosed spaces (bathrooms/storerooms): Upgrade to full-face gas mask with chlorine-rated cartridges. • Food processing areas: Add rubber boots + disposable hair cap (prevents bleach damage to hair/shoes). |
| 3. Critical Handling Rules | • Never test-spray toward people: Point nozzle away before triggering. • Skin contact: Immediately flood affected area with water for 10+ mins – do not wipe first. • Ventilation mandate: Always open windows + exhaust fans; position yourself upwind. |
| 4. Post-Use Safety | • Removal sequence: Apron → boots → gloves → goggles → mask → wash hands after each step. • Gear decontamination: Rinse gloves/goggles immediately; soak apron in water before washing. |
| Never Skip | Gloves + goggles + mask are absolute minimum. No exceptions – even for quick jobs. Full-face protection required in any confined space. |
