Exposure Controls
At any detectable concentration: Any self-contained breathing apparatus with a full facepiece operated in a pressure-demand or other positive-pressure mode.
Any supplied-air respirator with a full facepiece operated in a pressure-demand or other positive-pressure mode or other positive-pressure mode with an auxiliary self-contained breathing apparatus operated in pressure-demand or other positive-pressure mode.
Escape – any air-purifying, full-facepiece respirator with a high-efficiency particulate filler.
Any appropriate escape-type, self-contained breathing apparatus.
Firefighting and Other Immediately Dangerous to Life or Health Conditions
Use any self-contained breathing apparatus with a full facepiece respirator and a high-efficiency particulate filter.
Use any supplied air respirator with a full facepiece operated in a pressure-demand or other positive-pressure mode or other positive-pressure modes with an auxiliary self-contained breathing apparatus operated in pressure-demand or other positive-pressure modes.
Appropriate engineering controls:
- Avoid contact with skin, eyes, and clothing.
- Wash hands before breaks and immediately after handling the product.
Personal Protective Equipment
Eye and face protection:
- Face shield and safety glasses.
- Use equipment for eye protection tested and approved under appropriate government standards such as NIOSH (US) or EN 166(EU).
Skin protection:
- Handle with gloves.
- Gloves must be inspected before use.

EN374
If used in solution, or mixed with other substances, and under conditions that differ from EN 374, contact the supplier of the CE-approved gloves. This recommendation is advisory only and must be evaluated by an industrial hygienist and safety officer familiar with the specific situation of anticipated use by our customers. It should not be construed as offering approval for any specific use scenario.
Body protection:
- Complete suit protecting against chemicals.
- The type of protective equipment must be selected according to the concentration and number of dangerous substances at the specific workplace.
Respiratory protection:
Where risk assessment shows air-purifying respirators are appropriate use a full-face particle respirator type N100 (US) or type P3 (EN 143) respirator cartridges as a backup to engineering controls. If the respirator is the sole means of protection, use a full-face supplied air respirator. Use respirators and components tested and approved under appropriate government standards such as NIOSH (US) or CEN (EU).
