HEALTH & SAFETY CONSIDERATIONS

Handling Recommendations Use personal protective equipment (see MSDS)

Avoid all contact with skin and eyes

Do not inhale the vapors

Do not store in conditions outside of the recommended parameters

In case of a spill / leak, see MSDS.

For more information, please consult the MSDS

Application Safety While spraying, always work with adequate ventilation.

Protective gloves, overalls, eye protection, safety shoes, hard hats and a properly

fitting breathing apparatus supplying fresh air must be worn by the installers

(and others working within 25 feet of the installers) at all times while spraying.

Persons with known respiratory allergies must avoid exposure to the isocynanate

component.

If inhalation of the vapors occurs, remove the person from the working area to

 breathe fresh air and if breathing is still difficult, call a physician.

Avoid contact with eyes, skin and clothing.

In case of eye contact, immediately flush with large amounts of water for at least

15 minutes and call a physician immediately.

In case of skin contact, wash area with soap and water.

Wash any clothing that has come into contact with the isocyantate or resin before reuse.

inert gas. Application of large quantities of chemical spray is recommended for spill fires.

Personnel fighting the fire must be equipped with self-contained breathing apparatus.
