Featured Safety Guides

Personal Protective Equipment (PPE)

Minimum Required PPE

👁️ Eye Protection:

• Safety goggles - Stop chemical splash and debris
• Face shield - Extra protection when applying chemicals
• Never: Regular glasses (they don’t protect enough)

🧤 Gloves:

• Nitrile or rubber - Won’t break down from chemicals
• Long cuffs - Protect your forearms too
• Waterproof - Keep hands from being wet all day
• Never: Cotton or leather (they soak up chemicals)

👟 Footwear:

• Closed-toe boots - Chemicals won’t touch your feet
• Slip-resistant - Wet decks and concrete are slippery
• Waterproof - Dry feet make for longer work days
• Steel toe - Extra protection if something falls

👕 Clothing:

• Long sleeves - Protects from sun and chemical splash
• Long pants - Same deal for your legs
• Rain or chemical suit - If you’re applying chemicals all day
• Hat - Saves you from sunburn

Additional PPE (Situational)

🎧 Hearing Protection:

• When: Gas engines and loud electric motors are running
• What: Earplugs or earmuffs (both work)
• Why: Your hearing doesn’t come back

😷 Respirator:

• When: Indoors, enclosed spaces, or heavy chemical application
• What: N95 minimum, or a half-face respirator for chemicals
• Why: You need your lungs working

⛑️ Fall Protection:

• When: On roofs or working high up
• What: Harness, rope, anchor point (rated properly)
• Why: Falls kill. Use it every time.

Equipment Safety

High-Pressure Water Hazards

⚠️ WATER INJECTION INJURY

What it is:

• High-pressure water goes through your skin
• Looks like a tiny wound
• Actually damages tissue deep inside
• Needs emergency medical care right now

Prevention:

• Never point the wand at anyone, any animal, or yourself
• Never put your hand in front of the nozzle
• Lock the trigger when you’re not spraying
• Keep distance from the surface you’re cleaning

If injection occurs:

• Go to the ER. Now.
• Don’t try to treat it yourself
• Tell the doctor it’s a high-pressure injection injury
• The wound looks small but the damage is deep

Safe Operation Practices

Starting/stopping:

• Lock the trigger before the engine starts
• Use both hands on the wand when it’s pressurized
• Point the nozzle somewhere safe
• Bleed pressure before you put it down

During operation:

• Plant your feet where you won’t slip
• Know what’s around you at all times
• No kids or pets in the work area
• Take breaks before you get tired (tired mistakes are the worst)

Refueling:

• Engine off and cooled down
• Refuel outside, never in a shed or garage
• Wipe up any spilled fuel
• Hot equipment + fuel = fire

Nozzle Safety

Red nozzle (0°) WARNING:

• This nozzle injures people
• This nozzle destroys surfaces
• Use it only if you know exactly what you’re doing
• Never: On houses, vehicles, pets, or people

Nozzle changes:

• Machine off
• Trigger pulled to bleed all pressure
• Let the machine fully stop
• Then change the nozzle

Chemical Safety

Handling Sodium Hypochlorite (SH)

PPE required:

• Goggles (chemical splash protection)
• Gloves (chemical resistant)
• Long sleeves and pants
• Respirator if indoors or poor ventilation

Safe handling:

• Add chemical to water (backwards is dangerous)
• Mix where air can flow
• Label everything clearly
• Never mix different chemicals together

Storage:

• Cool, dry, with air flowing
• Out of direct sun and heat
• In the original containers
• Never near acids (creates poison gas)

Spill response:

• If it’s big, get people out of there
• Get air moving through the space
• Wear your PPE
• Soak it up with something inert
• Follow local rules for disposal

Chemical Application Safety

Before application:

• Look at what plants are nearby
• Cover them or rinse them first
• Close up the house
• Protect anything that can’t handle the chemical

During application:

• Know which way the wind is blowing
• Don’t spray too much
• Work on one section at a time
• Step away for fresh air sometimes

After application:

• Rinse the plants you covered
• Get air moving
• Clean your equipment
• Put chemicals back safely

Working at Heights

Ladder Safety

Before climbing:

• Check the ladder for cracks or damage
• Set it on flat, solid ground
• Extend it 3 feet past the roof edge
• Tie it off at the top

On ladder:

• Keep 3 contact points (two hands, one foot, or two feet, one hand)
• Don’t lean too far sideways
• Never stand on the top rung
• Hang tools from a belt, or use a rope for buckets

Roof work:

• ⚠️ SERIOUS: Roof cleaning kills people
• Think hard about hiring a pro instead
• Use real fall protection every time
• Never work on a roof alone
• Skip steep roofs entirely

Fall Prevention

Best practices:

• Use a harness and anchor point
• Use the ladder instead of climbing
• Use long wands so you don’t have to get high
• Think through the risk before you start

Fall protection basics:

• Harness that fits your weight
• Anchor rated for at least 5,000 lbs
• Know how to use the equipment
• Check it before every use

Electrical Safety

Water + Electricity = DEADLY

Never:

• Pressure wash near power lines
• Spray electrical outlets or switches
• Put extension cords in water
• Touch electrical stuff with wet hands

Outlet safety:

• Use GFCI outlets (they cut power if something goes wrong)
• Cover outlets when not in use
• Never use damaged cords
• Use outdoor cords for outdoor work

Extension cord safety:

• Use the right wire thickness (12 gauge is safer than 14)
• Keep connections dry
• Don’t run cords through water
• Uncoil it fully so it doesn’t overheat

Equipment electrical safety

Electric pressure washers:

• GFCI outlet every time
• Check the cord before you start
• Don’t use if it’s frayed or damaged
• Keep connections dry and off wet ground

Gas pressure washers:

• Never indoors (carbon monoxide kills)
• Keep away from flames
• Let it cool before fueling
• Make sure exhaust can escape

Job Site Safety

Site Assessment

Before starting:

• Look for hazards (power lines, drop-offs, slippery surfaces)
• Plan what you’ll do and when
• Set up zones so nobody wanders into the spray
• Tell the owner what you’re doing

During work:

• Pick up trash and debris
• Watch for things people can trip on
• Route hoses so they’re not in the way
• Keep people out of the work area

Protecting Property

Surfaces:

• Test on a hidden spot first
• Use the right pressure for the material
• Protect anything delicate
• Don’t spray windows (they break)

Landscaping:

• Rinse plants with water first
• Cover anything sensitive with plastic
• Rinse again after you’re done
• Never spray directly at plants

Fixtures and features:

• Cover any outlets
• Move or cover furniture
• Protect decorative stuff
• Don’t aim at lights or cameras

Weather-Related Safety
