A pair of goggles can save your eyesight from unexpected splashes or particles. Similarly, gloves protect your hands from chemicals or potential abrasions.
Maintain a safe distance from your cleaning surface. High-pressure streams can cause serious injuries if they come into contact with skin. I once witnessed a colleague accidentally hit his foot while trying to clean a stubborn stain, resulting in a painful injury that kept him off work for weeks. Keep the nozzle at least two feet away from the surface you’re treating, and adjust your stance to avoid any mishaps.
Check your equipment before each use. Ensure hoses and connections are secure and free from leaks. A small crack can lead to a sudden burst, resulting in a loss of control. I’ve had instances where a faulty hose led to unexpected spraying, making a simple job turn chaotic. Regular maintenance is key to preventing such situations.
Be mindful of your surroundings. Avoid using this equipment near electrical outlets or fixtures. I once had a close call when I was working near a power line, and a misdirected stream nearly caused a short circuit. Always be aware of potential hazards in your work area, including people, pets, and fragile items.

Use the correct cleaning agents. Not all detergents are suitable for high-pressure systems. Some can damage components or create harmful fumes. During a demonstration, I used an inappropriate cleaner, which not only clogged the machine but also produced a toxic cloud. Always read labels and choose products designed for your specific model.
Lastly, never point the nozzle at yourself or others. This seems obvious, but in a rush, it’s easy to forget. I once saw a newcomer accidentally spray his colleague while trying to clean a wall. It was a moment of panic that could have been avoided with a little caution. Always keep the nozzle directed away from people and animals.
