Safety - Weld-On


All Weld-On solvents cements and primers can successfully be used to solvent weld plastic piping systems when correct application and safety procedures are followed. Always read directions on our product labels and following these safety guidelines.

  • Do not use or store Weld-On products near sparks, heat, flame or other sources of ignition. Ensure that all equipment in the work area is electrically grounded to prevent sparks.
  • Do not smoke, eat, or drink when using Weld-On products. Ensure that the work area is well ventilated and avoid breathing the solvent vapors.
  • Wear NIOSH approved respirators when solvent welding piping systems in enclosed areas, or any area with inadequate ventilation.
  • Wear proper protective equipment (safety glasses and gloves).

NOTE: PVC and CPVC piping systems should not be used, or tested, with compressed air or gases. Compressed air or gas may contain stored energy that can result in catastrophic failure (including bodily injury, death, and/or property damage) if the piping system is breached. Use hydrostatic (water) pressure test only.

CAUTION: If Weld-On solvent cements and primer are used to install potable water piping system, do not use dry granular calcium hypochlorite, a water treatment chemical, to disinfect the piping system. Mixing the two may cause a volatile chemical reaction. Instead, use non-volatile chlorinated water to purify the piping system.
