Engineering controls:

Ensure adequate ventilation. The workplace shall have safe place to shower, clean eyes and body, and place for safe care.

Personal protection equipment

Respiratory protection:

No respiratory protection should be needed.

Hand protection:

Use chemical resistant gloves classified under Standard EN374: Protective gloves against chemicals and micro-organisms. Examples of preferred glove barrier materials include: Butyl rubber. Polyethylene. Chlorinated polyethylene. Ethyl vinyl alcohol laminate ("EVAL"). Examples of acceptable glove barrier materials include: Viton. Natural rubber ("latex"). Polyvinyl chloride ("PVC" or "vinyl"). Nitrile/butadiene rubber ("nitrile" or "NBR"). When prolonged or frequently repeated contact may occur, a glove with a protection class of 4 or higher (breakthrough time greater than 120 minutes according to EN 374) is recommended. When only brief contact is expected, a glove with a protection class of 1 or higher (breakthrough time greater than 10 minutes according to EN 374) is recommended.

Eye protection:

Use chemical goggles. Chemical goggles should be consistent with EN 166 or equivalent.

Skin and body protection:

Use protective clothing chemically resistant to this material.

Hygiene measures:

Avoid contact with eyes. Wash hands after handling. Do not eat and drink in the workplace.
