Is 3000 PSI enough to clean concrete
1. Install Local Exhaust Ventilation with High Temperature Duct Hose
Set up LEV systems near welding stations to capture gas at the source. Use high temperature duct hose to channel fumes away. Position the duct hose’s intake nozzle 10–15 cm from the welding arc. Ensure high temperature duct hose is straight to avoid kinks that block airflow. Secure the hose firmly to prevent dislodging during operation.
2. Choose the Right High Temperature Duct Hose Material
Opt for heat resistant and flame retardant high temperature duct hose. Silicone or fiberglass duct hoses work best for welding fumes. Avoid PVC hoses because they melt under welding heat. Select a duct hose with smooth inner walls to reduce clogging from welding spatter. Match the hose diameter to LEV system capacity.
3. Implement General Ventilation for Whole-Workshop Airflow
Pair LEV with ceiling or wall-mounted exhaust fans. Open windows and doors to create cross-ventilation. Use high temperature duct hose to connect fans to external vents. Ensure fans run continuously during welding and 30 minutes post-work. Adjust fan speed to maintain 4–6 air changes per hour.
4. Maintain High Temperature Duct Hose and Ventilation Systems
Inspect high temperature duct hose weekly for cracks, burns, or blockages. Clean the hose with compressed air to remove spatter buildup. Replace damaged duct hoses immediately. Because leaks release toxic gas back into the workshop. Service LEV filters monthly to preserve suction power.
5. Supplement with Personal Protection and Safe Practices
Wear N95 or higher respirators when ventilation is limited. Avoid welding in confined spaces without portable LEV. Position high temperature duct hose to avoid directing fumes at coworkers. Train staff to check duct hose and ventilation before each shift. Keep a gas detector nearby to monitor toxic gas levels.
