Gas Pressure Washers: Primary unique hazards include carbon monoxide poisoning (never use indoors), fuel handling and storage, engine heat, and generally louder operation requiring hearing protection. They often provide higher PSI and GPM for heavy-duty tasks.

Electric Pressure Washers: Primary unique hazards involve electrical shock (requires GFCI outlets, keeping cords dry, avoiding standing water). They are typically quieter, lighter, and more convenient for smaller, residential tasks.

E. How close is too close when pressure washing a surface? (Definitional/Boolean Question)

Generally, holding the pressure washer nozzle closer than 6 inches (15 centimeters) to a surface is considered too close. Getting too near can cause damage to the surface itself (e.g., etching concrete, splintering wood, stripping paint), and it significantly increases the risk of projectiles and kickback. Always start further away and gradually move closer if more cleaning power is needed, while observing the surface's reaction.

F. What are the signs of an injection injury, and what should I do? (Definitional/Actionable Question)

An injection injury might appear as a small, seemingly insignificant puncture wound, often with little pain initially. However, beneath the surface, there can be significant tissue damage, swelling, and internal bleeding. The area might become numb, tingle, or develop a throbbing pain hours later. If you suspect an injection injury, do not delay. Seek immediate emergency medical attention. Inform the medical staff that the injury was caused by a high-pressure stream, as these require specific and often immediate surgical intervention to prevent severe complications, including infection, tissue necrosis, or amputation.

G. Why is wearing closed-toe, slip-resistant shoes important? (Definitional Question)

Wearing closed-toe, slip-resistant shoes is crucial for multiple safety reasons. Firstly, they protect your feet from the powerful pressure stream itself, which can cause severe injury if it impacts exposed skin. Secondly, they guard against flying debris, such as rocks, dirt, or paint chips dislodged by the spray. Thirdly, and perhaps most commonly, they provide essential traction on wet and often slippery surfaces, drastically reducing the risk of slips, trips, and falls during operation.

H. Can pressure washers be used indoors? (Boolean Question)

Generally, pressure washers should not be used indoors. Gas-powered pressure washers must never be used indoors or in poorly ventilated areas due to the lethal risk of carbon monoxide poisoning. Electric pressure washers might be used indoors in very specific, well-ventilated situations where there is absolutely no standing water and appropriate electrical safety measures (like GFCI outlets) are strictly adhered to. However, it is highly discouraged due to the inherent risks of water spray near indoor electrical components, creating extremely slippery surfaces, and the potential for water damage.
