Minimize exposure in accordance with good hygiene practice. The OSHA PEL for MDI is 0.02 ppm, ceiling. These control limits do not apply to previously sensitized individuals or to individuals with existing respiratory disease, such as chronic bronchitis, emphysema, or asthma. Sensitized individuals should be removed from any further exposure. Exhaust air may need to be cleaned by scrubbers or filters to reduce environmental contamination.
Exceptions are when the material is sprayed or heated.
For emergencies, use a positive pressure self-contained breathing apparatus. Gloves determined to be impervious under the conditions of use. Depending on conditions of use, additional protection may be required such as apron, arm covers, or full body suit. Wash contaminated clothing before rewearing. Prevent skin and eye contact.
