Graco 313289s important safety instructions Overview, Isocyanate Hazard, Material Self-Ignition

Overview

XM sprayers are not approved for use in hazardous locations unless the base model, all accessories, all kits, and all wiring meet local, state, and national codes. See Models, page 7, to determine the appro- priate location for your particular model.

Isocyanate Hazard

Spraying materials containing isocyanates creates potentially harmful mists, vapors, and atomized partic- ulates.

Read material manufacturer’s warnings and material MSDS to know specific hazards and precautions related to isocyanates.

Prevent inhalation of isocyanate mists, vapors, and atomized particulates by providing sufficient ventila- tion in the work area. If sufficient ventilation is not available, a supplied-air respirator is required for everyone in the work area.

To prevent contact with isocyanates, appropriate per- sonal protective equipment, including chemically impermeable gloves, boots, aprons, and goggles, is also required for everyone in the work area.

Material Self-Ignition

Some materials may become self-igniting if applied too thick. Read material manufacturer’s warnings and material MSDS.

Overview

Moisture Sensitivity of

Isocyanates

Isocyanates (ISO) are catalysts used in two component foam and polyurea coatings. ISO will react with moisture (such as humidity) to form small, hard, abrasive crystals, which become suspended in the fluid. Eventually a film will form on the surface and the ISO will begin to gel, increasing in viscosity. If used, this partially cured ISO will reduce performance and the life of all wetted parts.

NOTE:

The amount of film formation and rate of crystallization varies depending on the blend of ISO, the humidity, and the temperature.

To prevent exposing ISO to moisture:

•Always use a sealed container with a desiccant dryer in the vent, or a nitrogen atmosphere. Never store ISO in an open container.

•Keep the ISO lube pump reservoir filled with Graco Throat Seal Liquid (TSL), Part 206995. The lubri- cant creates a barrier between the ISO and the atmosphere.

•Use moisture-proof hoses specifically designed for ISO, such as those supplied with your system.

•Never use reclaimed solvents, which may contain moisture. Always keep solvent containers closed when not in use.

•Never use solvent on one side if it has been con- taminated from the other side.

•Always park pumps when you shutdown.

•Always lubricate threaded parts with Part 217374 ISO pump oil or grease when reassembling.
